Annunciator panel should be suitable to mount on a standard ‘old-work’ style two-gang back box.

Strobe lights shall not be provided for this purpose.

• Status Indicators: The Annunciator panel shall indicate the following conditions: “System Ready,” “Trouble” (to include water pressure insufficient, insufficient water flow, low water level in tank, low temperature in TPS closet, etc.), and “Pump Running.” Annunciation of the cause of the Trouble signal shall not be provided at the Annunciator panel, but it shall be clearly evident at the Control Panel.

• Audible Alarms: Annunciator panel shall have an audible alarm signal that alerts to the conditions listed below. The alarm is intended only to draw attention to the panel so that the occupants will become aware of a problem and call for maintenance. This is not intended to be a fire alarm; the smoke alarms in the home perform that function. The audible signal may be the same signal for each of the conditions that could initiate an alarm; a separate sound is not required to distinguish between a trouble alarm and a pump running alarm.

• Pump Running Alarm

• Trouble Alarm

• Visible Indicators: Annunciator panel shall have visible indicators to provide current system status. LED lamps or an LCD screen may be used (e.g., a digital thermostat or residential security system panel). The indicators shall be color-coded as listed below.

• A green System Ready indicator shall be illuminated to indicate all system components are ready for use and in their normal state. Indicator shall be suitable for 10 years constant ON use.

• Both the exterior alarm and the pump running alarm on the Annunciator Panel should alarm simultaneously when the pump is running.

B.6: PLUMBING

• Connection to Sprinkler Riser: Provide a connection between the INTERNAL TPS and the sprinkler riser. The connection shall have a flexible hose or tube, 1-inch inside diameter or larger. The hose shall be long enough that the weight of the filled hose will bear on the floor instead of on the sprinkler riser; the sprinkler riser shall not be required to bear the weight of the filled TPS hose.

Include a 1-inch female Cam Locking connection on the hose to connect the TPS plumbing to the sprinkler riser provided by the MHU manufacturer in the home. Sprinkler connection in the MHU is an aluminum 1-inch male Cam-Locking fitting.

• Sprinkler system, point of connection, is located on the left side of the TPS closet (when viewing from TPS closet door), 2 – 4 inches above the finished floor, 16-20 inches from the exterior wall of the INTERNAL TPS closet.

• Cam-Locking connectors shall comply with the most current edition of Commercial Item Description A-A-59326, General Specification for Coupling Halves, Quick Disconnect, Cam- Locking Type. Connections shall be Class A, Style 2.

• Provide two spare gaskets for the Cam-Locking connector with the TPS parts kit.

• Gaskets shall be suitable for potable water service.

• Test loop: The INTERNAL TPS shall have a pump test loop that flows not more than 14 GPM to simulate activation of a single sprinkler. The orifice size in the test loop shall be determined based on the water pressure produced at the TPS.

• Test Sequence: INTERNAL TPS test sequence shall be initiated by operating the button or switch on the TPS control panel. Test sequence shall test the TPS controls and alarms and shall operate the pump. Operation of the test loop shall activate both the exterior alarm and interior pump running alarm and allow the water to return to the storage tank.

• Strainers: Pressure gauges, pressure sensors, and other small-orifice devices shall be protected against clogging by a Y-strainer with a US 50 Mesh strainer to prevent clogging of the small passageways.

• Corrosion Prevention: In sections of pipe containing or leading to system control components, piping material and configuration shall be designed and fabricated to prevent corrosion inside the pipe during long periods of storage. The system shall be configured to permit complete drainage of the pipe by gravity when the drain valve(s) is open. The design basis shall include the presumption that some water remains inside the pipe after drainage and the design must preclude corrosion from this standing water.

• Horizontal runs of pipe in sections of pipe containing or leading to pressure sensors, gauges, solenoid valves, motor-operated valves, or other components intended to monitor or control the system are discouraged.

• The use of solenoid operated valves in the INTERNAL TPS system is prohibited.

• Tank Fill Connection/Valve: The tank fill connection and INTERNAL TPS piping shall be configured to permit pressurization of the MHU sprinkler system from a garden hose for low-pressure testing of the sprinkler system prior to INTERNAL TPS startup. The tank fill connection shall have a screw-in plug to prevent any leakage during operation; plug shall be attached to the TPS with a tether to lessen the chance of it being lost.

• Drain: The INTERNAL TPS shall be configured to permit removal of all water from the tank, pump, and piping by gravity flow without the need for electrical power to the unit. Drains shall be arranged to prevent water spilling inside the MHU.

The Drain and Vent Manifold provided by MHU manufacturer will have 1-inch diameter female NPT connections for tank drain. TPS manufacturer shall provide all fittings required to connect the INTERNAL TPS overflow to the manifold.

B.7: Pressure Sensors

• Either standard pressure switches or pressure transducers may be used in the TPS subject to the requirements below. Pressure sensors should have a fluid connection of not less than ¼ inch diameter.

• Replacement pressure sensors must be readily available. TPS manufacturer shall identify and successfully test not less than two commercially available sensors from different manufacturers that can be used in the TPS without the need to rewire or reprogram the PLC. These shall be listed in the parts breakdown in the O&M manual provided with the TPS, and the TPS manufacturer shall commit to maintaining in inventory of replacement sensors.

• Pressure sensors shall be installed in the TPS plumbing system in a position and location so that it is not possible for liquid water to pool inside the sensing port or opening of the sensor when the TPS is drained of water using the system drain valves and draining instructions provided in the operations and maintenance manual. The intent of this requirement is to reduce or eliminate the potential for damage to the sensor by either (1) microbial growth inside the sensing port or pipe leading to the port, or (2) the buildup of scale or mineral deposits inside the sensing port or pipe, or (3) freezing of trapped water.

FEMA has no control over the quality of water available at the installation sites, and experience has shown that each of these phenomena has occurred and resulted in failure of the sensor and/or the need for troublesome repairs.

• Where pressure transducers are used, the piping configuration shall be configured to reduce or eliminate direct pressure wave influx into the sensing port. One way to accomplish this, at the discretion of the TPS manufacturer, is to use a snubber fitting gauge protector to protect the pressure transducer from the hydrodynamic forces of pump startup. If snubber fittings are used, the TPS parts kit shall include not less than one spare snubber fitting for field replacement if the original snubber becomes clogged.

• If pressure transducers are used, the transducers shall not be installed into the TPS prior to shipment. New-in-box transducer(s) shall be shipped as part of the installation parts kit with each TPS unit, and the installation instructions for the transducers shall be integrated into the O&M manual.

o The pipe opening or port where the transducer is to be installed shall be shipped with a contrasting, brightly colored plug to seal the opening during storage and to make locating the proper opening easier during field installation.

o Pipe thread dope or tape that is required to ensure a leak-free transducer installation shall be pre-installed onto the transducer where the transducer has male threads.

Where a transducer has female threads, the dope or tape required for installation shall be packaged with the transducer.

o Recognizing the fact that the transducer can be easily damaged by over-torquing during installation, a brightly colored tag with appropriate cautionary statements and instructions shall be attached to the transducer by wire or plastic tie so that the installer must remove the tag before the transducer can be installed.

B.8: INTERNAL TPS Control Panel

• Control Panel: The INTERNAL TPS control panel shall be located inside the TPS closet and shall control all TPS functions and alarms. The control panel shall be positioned so that the operator’s controls face the door of the TPS closet.

All alarm and trouble conditions reported at the Annunciator Panel should also be reported at the Control Panel; different presentations are permissible. The information available at the Control Panel shall be more complete than that which is available at the Annunciator Panel, and that a maintenance technician shall be able to diagnose and troubleshoot the TPS from the Control Panel.

Audible alarms in the Control Panel are intended only for notification of the maintenance technician in the TPS Closet, not for MHU occupant notification.

• System Reset: The control system should automatically reset the INTERNAL TPS to normal operating mode following a test, activation, trouble alarm, pump running alarm, loss, and restoration of power (i.e., after a thunderstorm or maintenance activity), or other plausible system event. Provide a manual system reset switch on the Control Panel. Upon operation of the

TPS reset switch, the alarm silence feature shall be reset to normal status; any active alarm silence timer shall be cancelled unless the condition that triggered the alarm remains active after the reset.

• Startup: INTERNAL TPS shall not require any programming or adjustment at startup or reset.

Startup shall normally be accomplished by operation of main power switch on the Control Panel.

All system settings should be set at the factory. Time delays and other settings should be capable of being changed if field conditions required but shall require a manufacturer’s password that is not listed in the Operation and Maintenance manual. Pressure switches, water flow switches, thermostats, and any other device that can be adjusted shall be adjusted for proper operation at the factory. The startup instructions shall not require the installer to make any adjustments as a normal course of action. The troubleshooting section of the operation and maintenance manual should clearly describe when adjustments are necessary and how to perform them.

• Water Level Monitor: A Water Level monitor shall activate a Trouble Alarm when the water level falls below the INTERNAL TPS manufacturer’s recommended minimum tank level. (The visible and audible Trouble indicators shall both operate when the water level is low.)

• Diagnostics and Troubleshooting: A PLC based Control Panel shall provide trouble codes and other information that will be useful for diagnostic and troubleshooting. On analog panels, use LED lamps to indicate trouble conditions, in sufficient number, and with clear labels to aid in complete troubleshooting.

• Manual Test Feature: The Control Panel shall provide a system test feature that is manually activated via the appropriate switch. If the system fails the manual test, the Control Panel shall provide trouble code(s) or other means to identify the source of the failure.

• System Test Switch: Provide a System Test button or switch on the outside of the Control Panel.

System Test button shall activate the test loop to simulate the flow of one sprinkler, testing the pump start and the alarms. This switch does not require tamper protection. Automatic testing of the TPS unit is not desired. Test sequence program should permit the test sequence to continue if a non-fatal fault is discovered (i.e., system pressure low but greater than zero), and the system shall display the results of the test along with any fault codes.

• Alarm Silence Feature: An alarm silence feature shall be included that overrides the audible portion of both the Pump Running alarm and the Trouble alarm (at both the Annunciator Panel and at the External Alarm) but shall not override any of the Alarm visual indicators. Each activation of the Alarm Silence button shall silence the Alarm for 24 hours from the time of that activation. Multiple activations of the Alarm Silence button should not result in an increase in the period of time that the alarm is silenced, i.e., button presses are not additive. The Silence feature may be activated every 24 hours as needed. Provide alarm silence capability at both the Control Panel, and on the Annunciator Panel. The 24-hour clock shall be reset when the system reset button is activated (which may result in the alarm reactivating if the condition that tripped the alarm has not been remediated). Activation of the alarm silence button from the TPS control panel only shall silence both audible alarms for a period od 7 days or until the alarm is fixed and reset by a technician.

• Room Temperature Monitor: Provide a room-temperature monitoring capability with the TPS.

Attaching the sensor to the outside bottom of the control panel enclosure at the factory is preferred over a setup step that requires placement of the sensor. Temperature monitor shall be configured to activate the TPS Trouble Alarm when the temperature falls below 40°F. Provide a clear indication at the Control Panel of a low-temperature condition that initiates a Trouble alarm.

• Include a means to verify operation of the room temperature monitor; this can be as simple as a ‘stick-on’ thermometer on the control panel.

B.9: Interface with MHU electrical

• Point of Connection: AC power supply to the INTERNAL TPS shall be provided via a standard

4-pole, 30 Amp, 240 VAC, NEMA 14-30 dryer receptacle and plug.
