3.3 Reprogram/Reconfigure Releasing Panels

a) Hangar bay with multiple foam risers - Verify that the foam releasing panel is not configured to release foam if the pressure switch in one foam riser is activated. If the panel is configured to release foam from a pressure switch activation, reprogram/reconfigure the releasing panel to remove this function. The foam riser pressure switches should cause an alarm but not activate any release solenoids.

b) Test that the activation of a pressure switch or an individual heat detector will not activate the foam system. Test that the activation of cross zoned heat detectors will activate the foam system. System may be tested without actual discharge of water or foam.

c) Reroute conduit such that it does not enter the top of the foam/water releasing panel

3.4 Replace manual foam releasing (start) stations and conduit

a) Demo all existing releasing stations, associated wiring and conduits as required.

b) Install new water tight ¾” conduit and junction boxes from the releasing stations to a height of 15 feet above the finished floor or until the conduit intersects a horizontal run.

Route the conduit into the bottom of the manual foam releasing stations. Provide the low point of this conduit with a drain (See figure 1). Where the conduit is in a hazardously classified area, provide breathers in isolated portions of the conduit (e.g. sealed off from the remaining conduit system). Rate drains and breathers for the electrical (hazard) classification in which they are installed, but not be less than NEMA 250 Type 4. Flexible conduit is not permitted.

c) Install new NEMA 250 Type 4 manual foam releasing stations and signage.

The releasing stations shall be distinctively different from the manual fire alarm pull stations.

Provide tamper cover with colored portions in yellow and lettering on the cover reading "FOAM";

the words "FIRE", "ALARM", or "AGENT" are prohibited to appear on the cover or station.

Provide locking type manual foam releasing stations that when activated require a key to be reset.

Provide a clear plastic tamper cover over the manual foam releasing station that when lifted emits an audible alarm. Exception: Audible alarm is not required where a manual foam releasing station is installed in a hazardous (classified) location.

Provide conventional manual foam releasing stations. Do not locate addressable monitor modules for the manual foam releasing stations in the hangar bay. Approved model is RSG RMS-EX-WP or approved equivalent.

Install manual foam releasing stations within the hangar bay so they are unobstructed, readily accessible, and located within 10 ft. (3.0 m) of each required exit or exit access from the hangar bay. Maintain a minimum separation distance of 5 ft. (1.5 m) between general fire alarm pull stations (if provided) and the manual foam releasing stations. Where possible, install the manual foam releasing stations on the opposite side of the door from the general fire alarm pull stations. If possible locate the releasing station and sign so that a future stop station and sign may be installed per figure 1.

Control valves shall be electrically supervise normally open control valves.

Electrical or mechanical supervision is not required for normally closed control valves, unless opening the valve is detrimental to the system operation. When supervision is required on normally closed valves, provide electrical supervision such as cable type monitoring.

d) Provide the sign for the manual foam releasing station with a yellow or lime-yellow background with "START FOAM SYSTEM" in red lettering not less than 3 inches (76 millimeters) high. The a sign a minimum of 24 inches (610 mm) high by 20 inches (508 mm) wide.

Locate the manual foam releasing station with tamper cover on the lower portion of the sign. Provide the word "START" in minimum 1 inch (25.4 mm) high green lettering placed directly above the manual foam releasing station.

e) Install new wire as required. All conductors must be 16 AWG minimum. Pull all conductors splice free; conductors shall be continuous from device to device. The use of wire nuts, crimped connectors, or twisting of conductors is prohibited.

f) Test the system in accordance with the procedures outlined in NFPA 72. The tests shall be witnessed by the Owner's Representative and test results recorded. The required tests for the releasing station circuits are as follows:

(1) Loop Resistance Tests: Measure and record the resistance of each circuit with each pair of conductors in the circuit, short-circuited at the farthest point from the circuit origin.

(2) Verify the absence of unwanted voltages between circuit conductors and ground.

(3) Visually inspect wiring.

(4) Test each release station and circuit for proper operation and response at the control unit and tested in accordance with manufacturer's recommended calibrated test method.

3.5 Install Surge Protection Devices

Install Surge Protection Devices (SPDs) to protect all power supply circuits to the Fire Alarm and Foam releasing panels, including any subpanels (e.g. Autonomous Control Unit, amplifier panels, and Notification Appliance Circuit (NAC) booster panels). Provide SPDs to protect all signaling line circuits, indicating device circuits, or notification appliance circuits that leave or enter a Facility’s exterior enclosure. SPD must be provided at the first location where connections are made that is close to where the circuit enters or leaves the Facility, prior to connection to any other devices when feasible. SPDs are not required for devices connected directly to the Facility exterior when the Facility itself is provided with lightning protection (i.e. an electric bell or speakers mounted on the exterior wall of the Facility.) SPD shall have both a UL 1449 and UL 1283 listing and shall be located in an adjacent terminal box unless the SPD is listed and installed in the control panel by the factory (e.g. Installing SPDs not listed with the panel is prohibited). A typical installation is shown in figure 2. Provide and install SPDs in accordance with UFC 3-520-01 Section 3-4, NFPA 780-28 Section 4.20., and NFPA 70 National Electric Code.
