i. 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 4. Flexible conduit is not permitted. Conduit is to be red.

ii. Install new NEMA 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 conventional manual foam releasing stations. 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.

iii. Install manual foam releasing stations in the facility so they are unobstructed and readily accessible. 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. If possible locate the releasing station and sign so that a future stop station and sign may be installed.

iv. 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 sign shall be 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.

v. 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.

b. Install a surge protection device (also referred to as TVSS or SPD) on the releasing panel.

SPD shall have both a UL 1449 and UL 1283 listing and shall be located in an adjacent hinged 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).
