FMD-310-001 Revision Date: 01/2024

Piston Accumulator (PA) The Fogmaker piston accumulator is a cylindrical container made of anodized aluminum that houses a floating piston which separates the cylinder into two sections. One end of the cylinder referred to as the bottom holds compressed nitrogen gas, the top end of the cylinder houses the compressed suppression liquid. The suppression is capped with a valve on the cylinder cover.

NOTE: The PA is pressurized to approximately 65 bar (945 psi) at 20°C (68°F).

The PA is mounted outside the protected area in an area that is not to exceed 65°C (150°F). On transit buses they are often located behind the light panel or in a compartment behind the rear seats. On school buses they are typically under the vehicle in a protection box. On off road vehicles it will typically be in some type of protection box on the body of the vehicle. Follow the hose from the protected area to locate the exact placement.

Production date / serial number / pressure / volume.

a) Note the production year and serial number of the piston accumulator, found on the service label on the outside of the cylinder. The serial number can be found on top expressed in numbers and the production date is punched in a table. If the serial number cannot be read, the chassis number stamped on the bottom of the piston accumulator can be given instead.

b) Read the pressure in the container on the gauge.

c) Note volume of suppressant on the checklist, stated on safety label.

The functionality of the piston accumulator The valve opens and closes the piston accumulator and the safety screw locks the valve mechanism.

The safety screw must always be installed in the release valve during transport, installation and service.

When the safety screw is removed, the suppressing agent in the Fogmaker® unit can be discharged. The release valve must not be removed when the system is pressurized. If the release valve or any of the nipples or connectors in the system are removed when the system is pressurized, the suppressing agent can be discharged unintentionally, resulting in serious personal injury.

On gen 1 valve bodies the safety screw is inserted through the face of the valve as shown in the following photos.

On gen 2 valve bodies have a hole on the side of the valve body that the screws are inserted into. The red screw prevents the system from discharging and must be fully threaded in to prevent discharge. The green screw is used in it place to prevent debris from entering the valve body and when a safety switch is used the green screw has a magnet that closes the circuit.

Safety switch - Micro switch Amicro switch may be mounted on the gen 1 valve that is held closed with the safety screw. Perform a functionality test of the micro switch by removing the safety screw and checking that alarm panel changes to the service system or system isolated mode depending on the panel style.

A safety switch may be mounted on the gen 2 valve that closes the circuit when the green screw with a magnet is inserted into the safety screw port on the side of the valve. Perform a functionality test by removing the green screw and checking that alarm panel changes to the service system or system isolated mode depending on the panel style.

Damage - Leaking Visual inspection of piston accumulator, brackets and mounts.

The body of the PA must be inspected for damage. If any damage exceeding the following guidelines is found the PA is to be scrapped.

No grooves deeper than 1/32" (.8mm) in the collar (area shaded yellow).

No grooves deeper than 1/16" (1.6mm) in the rest of the body (area shaded blue).

No dents deeper than 1/32" (.8mm) anywhere on the PA.

A depth gauge similar to the one shown can be used to determine the depth of the damage as long as the end is narrow enough to fit in the groove.

Check for leaks:

a) Remove the distribution hose / pipe connected to the fitting on the valve.

b) Check for signs of fluid inside the fitting.

c) Check for signs of seepage around the fitting and washer at the valve body.

The protection box Check protection box condition.

a) The protection box must be properly installed and not have any damage that might have damaged the contents or reduced the protection of the contents.

b) Check the mounting of the protection box and the mounting of piston accumulator in the protection box.

c) Check that labels are readable and fully visible, See Labels and Seals section.

Refilling - Resetting Only trained service personnel may perform refilling/resetting Contact your local service partner.

Detection Cylinder The detection cylinder contains a liquid that is pressurized by nitrogen to 24 bar (348 psi) before installation. The cylinder has a pressure switch to warn if the pressure drops below 14 bar (203 psi). The cylinder has either a ball valve (pre -2023) or collar valve (after 8/2-2022) that must be open prior to arming and anytime the system is active. Closing the valve does not deactivate the system and may over time cause the system to discharge.

In the fall of 2022 the detection cylinder transitioned from using a ball valve to turn it on and off to a rotating collar valve. This change the position of the pressure switch from before the valve to after it so that the pressure in the detection tubing is always being monitored.

Serial number and pressure.

a) Note the serial number found on the label of the detector bottle. If the number is not visible, note the chassis number that is stamped on the bottleneck.

b) Also check the condition of the rest of the labels.

c) The bottle pressure can be checked on the gauge on the top of the bottle and should be within the green area.

d) Verify the mounted position and that the valve is level with or above the center of the detection cylinder.

BALL VALVE COLLAR VALVE OFF (LOCKED) COLLAR VALVE ON (UNLOCKED)

Stamped DOT & Date code Inside the cylinder Mounting Positions

Alarm and Cabling A pressure switch on the piston accumulator gives a service warning if the pressure falls below 50 bar, a pressure switch on the detection cylinder gives a service warning if the pressure falls below 14 bar, and if equipped the safety switch gives a service warning if the screw is removed. The fire alarm is triggered only when both pressure switches send the alarm panel an open signal. The cable condition and functionality must be checked during the inspection.

General functionality Check that visible cables and/or accessible cables and cable protection are undamaged.

Perform systems test by pushing the test button on the alarm panel.

In order to test the alarm function, disconnect the connector to the pressure switch on the detection cylinder. Verify the panel has switched to show a service fault. Then also disconnect the connector to the PA and verify that the panel has switched to FIRE mode. Reconnect the detection cylinder connector and verify the panel returns to a service fault.

Reconnect the PA connector and verify the panel returns to a system okay status with a green light. If equipped with a safety switch, remove the safety screw (gen 1) or green magnetic screw (gen 2) and verify the panel has switched to a service fault.

For panel specific information please see the corresponding owners manual.

Distribution system The distribution system consists of distribution hoses, pipes and fittings, and spray nozzles. Their task is to distribute the suppressant from the piston accumulator out into the fire protected area.

Mounting All fittings must be properly in place, for pipes as well as clamps. Pipes must be fitted with steel rubber clamps. The distribution hose must be fixed with steel rubber clamps or cable ties. The minimum distance between two attachment points is 16" (400 mm), the maximum distance from the end part to the nearest attachment point is 4" (100 mm).

In the event of incorrect installation - contact an authorized service partner to remedy this.

Damage and leakage

a) Clamps that keep pipes and hoses in place must be tightened, but there should be no abrasions on distribution hoses or pipes, check that they still have the rubber protection intact.

b) Check that pipes and hoses are not exposed to a hot or sharp surface that could damage them.

c) Check distribution hoses for damage resulting from sunlight, age and similar. Pay extra attention to hoses on the exterior of machinery, which are exposed to the elements.

Distribution system leak test Only trained service personnel may perform leakage tests. Contact your local service partner.

System reset after deployment Only trained service personnel may perform system resets. Contact your local service partner.

IMPORTANT

REGARDLESS OF THE CAUSE OF A DISCHARGE

TO PROTECT THE COMPONENTS IN THE PROTECTED AREAS AGAINST CORROSION,

FULLY FLUSH THE AREA OF ALL SUPPRESSION FLUID AS SOON AS POSSIBLE AFTER DISCHARGE.

USE OF A HIGH PRESSURE WASHER IS RECOMMENDED

Hydro-pneumatic detection Hydro-pneumatic detection means automated mechanical activation of the fire suppression system in case of fire. The detector tube, filled with liquid and pressurized to between 20 and 24 bar, bursts at a temperature of 375°F (170°C). The detection tube is protected by a protective conduit/coil to avoid damage, Inspecting the system detector tubing.

All sections of detection tube outside of the protected area must be covered with the protective conduit. Check the condition of the conduit.

The tubing in the protected area must be covered by the protective coil. Check the coil for breaks and kinks. Are the ends bent or coiled such as not to damage the tubing?

Does the tubing show any signs of wear or swelling? A damaged detector tube will burst at a lower temperature than intended, which increases the risk of unintentional activation. Swelling may be an indicator of higher than designed temperatures and require that the tubing be rerouted.

Are tubing inserts visible? If so is there more than 1/8" (3mm) showing?

Signs of damage to the detection tube, protective coil or conduit would require replacement by trained service personnel.

Inspecting the system mounts.

Is the detection tubing secured in a way that prevents sagging?

Are the clamps in good condition? Replace clamps with damaged or missing isolators.

Are cable ties used? Are they at least 3/8" wide? If not is a section of protective conduit over the coil? Are the ties in good condition?

Electrical - hydro pneumatic activation The electrically activated actuator is used to create a manual activation option for the fire suppression system's hydro-pneumatic detection. This is complementary to the automatic function.

The electrically activated actuator (punch or metron) is mounted on the detector tube and connected to an activation button placed by the driver's seat. When the button is pressed, the detector tube is punctured and the fluid leaks causing the system to discharge.

Electrical activation inspection.

Verify to have a replacement Break Away Tie prior to testing the electrical activation.

Visually inspect all accessible sections of the harness for damage.

Verify the harness connection to the electric punch.

Disconnect the electric punch red harness from the main harness-. Plug the push button tester into the electric punch connector on the main harness. Verify that the connector on the red wires is NOT connected.

On vehicles using the Smart panel, the service required alarm should sound and the display a "Fault, Check Metron" fault.

Leave the punch disconnected through the inspection process.

Inspect the activation button for signs of damage or tampering.

The following "while seated" sections apply to on road vehicles.

Verify that the activation button is within reach of the operator while seated.

Verify the pull pin can be removed while seated.

Verify the tester is plugged in, then pull the pin and depress the button. You should hear the alarm buzz.

In the absence of a tester a test light or multimeter can be used to verify there is current when the button is pressed.

Replace the pull pin and replace the break away tie. NEVER use a standard cable tie.

Resetting an electrically activated system.

Only trained service personnel may perform resetting. Contact your local service partner.

Mechanical - hydro pneumatic activation The mechanical actuator is used to create a manual activation option for the fire suppression system's hydro-pneumatic detection. This is complementary to the automatic function.

The manual actuator is connected directly to the detection tubing. When the pin is pulled and the knob is depresses the pressure drops causing the system to discharge.

Mechanical activation inspection.

Verify that the manual activation assembly is free of damage and shows no signs of tampering.

Check the fittings for signs of damage or leaks.

Remove the cap from the discharge port and inspect the port for damage and debris.

Reinstall the discharge port cap.

Resetting a mechanically activated system.

Only trained service personnel may perform resetting. Contact your local service partner.

Finishing up Annual inspection and service is performed on the vehicles and other installations that have the Fogmaker fire suppression system installed. After each inspection, a Service Inspection checklist is filled in which lists all the points outlined in this manual. The checklist must include basic information such as work order, date, location, customer, vehicle type, Vehicle ID number, component serial numbers, signatures and contact details.

The inspection form is attached at the end of this manual and available from Fogmaker North America.

Verify the following if applicable:

That the electric activation button pin and breakable tie are in place. Only 1 tie should be used.

That the electrical activation punch is connected to the harness.

That the manual activation button pin and breakable tie are in place.

That and components removed during the inspection are reinstalled.

That the safety screw and green screw are in the correct position for the system to be active.

That the alarm panel is showing the system is Okay for service.

Service Control Plan Service Intervals Daily The operator must verify that the display panel's green System Okay light is illuminated.

For systems without a display panel, the pressure in the piston accumulator and detection cylinder pressure gauges must be checked to verify the indicator is in the green swept area and the valve body must be checked to ensure that the safety screw is not installed.

Monthly If the system does not have a display panel, these checks must be done weekly.

Verify that the pressure gauge indicators are in the green swept area. That there are no signs of leakage. That there are no signs of damage.

Quarterly If the protected equipment is used in a severe environment, the below annual inspection must be done quarterly.

Quarterly inspections can be based on the vehicle in service date as long as it does not exceed 12 months from the piston accumulator manufacture date.

Semi-Annually UL listed systems must have the below annual inspection every six months.

Semi-Annual inspections can be based on the vehicle in service date as long as it does not exceed 12 months from the piston accumulator manufacture date.

Annually An inspection by a trained and currently certified technician must be performed on intervals not to exceed 12 months. The specifics of the inspection are described in the Control Plan for Annual Service section below.

Annual inspections can be based on the vehicle in service date as long as it does not exceed 18 months from the piston accumulator manufacture date.

Five year In addition to the annual inspection:

The suppressant must be replaced and the release valve body serviced.

Detection cylinders must be hydro-tested or replaced.

The five year service is based on the piston accumulator manufacture date or the latest refill date.

Ten year In addition to the annual inspection:

The piston accumulator must be hydro-tested or replaced.

The detection cylinder must be hydro-tested or replaced.

If equipped, the electronic activator (metron) must be replaced.

The ten year service is based on the piston accumulator manufacturer date.

The 5 and 10 year services may only be performed by authorized personnel with additional training and certification.

The safety screw must always be installed in the release valve during transport, installation and service.

When the safety screw is removed, the suppressing agent in the Fogmaker® unit can be discharged. The release valve must not be removed when the system is pressurized. If the release valve or any of the nipples or connectors in the system are removed when the system is pressurized, the suppressing agent can be discharged unintentionally, resulting in serious personal injury.

Only FMNA components shall be used in the FMNA system. If other components are used, FMNA will not guarantee the system function.

Arming The System The Fogmaker North America fire suppression system features a safety screw to lock the release valve from opening during shipping and servicing. The piston accumulator is equipped with a safety switch which is to ensure that the piston accumulator is armed. Until the system is fully armed, the alarm module will display a "Service System", "Fault" or "FIRE" warning depending on the module being used.

Failure to follow arming procedure can result in accidental discharge of fire suppression system Check all detection line fittings. Ensure that only the tip of the support sleeve is visible.

Failure to correctly install FM-4249 support sleeve in detection line fittings may result in an accidental discharge of fire suppression system

Verify that the end of the detection line has a clean square cut using FM-1809 tubing cutter. Insert an FM-4249 support sleeve into the detection line end.

Install the detection line fitting. Verify that the fitting has been fully inserted by inspecting the length of the support sleeve that is still visible. Only the chamfered tip of the support sleeve shall be visible.

If the tubing is not fully inserted the fluid will seep out of the fitting and cause the system to discharge.

../ANSI Z535 SYMBOLS/NOTICE.jpg

Prior to arming the system, the suppressant pressure is in the valve body pushing the small piston into the latch arm. The red safety screw is keeping the system from discharging.

Up to September 1, 2022 the detection cylinder has had a 1/4 tun ball valve to pressurize the detection tubing circuit.

When the handle was perpendicular to the valve, it was off

When the handle is in line with the valve, it is on and the line is pressurized.

This is also the position when filling the cylinder.

The new valve is a ring around the collar with an arrow. When the arrow is pointing to the closed lock, it is off.

When the ring is rotated so the arrow is pointing to the open lock it is on and the line is pressurized.

The new collar has a pin that is inserted when the valve is locked (off)

The pin is stored in the flange of the collar when the valve is unlocked.

Turn the detection cylinder valve on to pressurize the detection line. You should hear the detection fluid entering the detection tubing typically followed by a metallic sound of the latch arm being pushed off the red safety screw and against the valve body.

Verify the gauge indicator stays in the green near the 24 bar mark. Check the detection circuit for any signs of leakage.

REMOVING THE RED SCREW BEFORE

PRESSURIZING AND CHECKING THE DETECTION CIRCUIT

WILL CAUSE THE SUPPRESSANT TO DISCHARGE!

If needed, use a 10mmwrench to loosen the red safety screw by turning it no more than 1/2 turn.

DO NOT FULLY REMOVE THE SCREWWITH THEWRENCHOR SOCKET!

The red screw should be able to be removed by hand. If the red screw cannot be removed by hand, re-check that the detection cylinder valve is open and has pressure.

Remove the green screw from the face of the safety switch and install it into the hole that the red screw was removed from. Install the red screw into the hole that the green screw was removed from. Tighten these only finger tight.

Once the screws have been swapped, the contacts within the safety switch should close and the alarm panel should display a green SYSTEM OKAY screen.

When capable, verify the pressure in both cylinders has not dropped after being armed for 24 hours.

Disarming The System Disarming is not typically recommended, but in the rare occasion it is deemed necessary it is accomplished as follows.

CLOSING THE BALL VALVE ON THE DETECTION CYLINDER DOES NOT DISARM THE SYSTEM AND OVER

TIME WILL LIKELY CAUSE AN UNWANTED DISCHARGE

To properly disarm the system the arming steps are done in reverse. The red and green screws on the PA valve need to be switched so that the red (longer) screw is moved from the face of the safety switch into the port on the side of the valve.

Make sure the red screw is fully installed so that it will prevent the hammer inside the valve from being able to move past it.

After the screws are swapped the valve on the detection cylinder can be closed.

The RED safety screw is the only thing that disarms the system. Turning off the detection cylinder valve is only done to prevent the detection cylinder from emptying if the detection tube is damaged or disconnected.

To prevent the detection cylinder from emptying, the valve needs to be turned off.

Depending on the style of valve, either close the ball valve.

OPEN CLOSED

Or rotate the collar from the unlock icon to the locked icon.
