               5.      Where possible, locate waterflow switches a minimum of one (1) foot (305 mm) from a fitting which changes the direction of the flow and a minimum of three (3) feet (914 mm) from a valve.

        I.      Sprinkler and Standpipe Valve Supervisory Switches:

               1.      Each sprinkler system water supply control valve riser, zone control valve, and standpipe system riser control valve shall be equipped with a supervisory switch. Standpipe hose valves, and test and drain valves shall not be equipped with supervisory switches.

               2.      PIV (post indicator valve) or main gate valves shall be equipped with a supervisory switch.

               3.      The switch shall be mounted so as not to interfere with the normal operation of the valve and adjusted to operate within two revolutions toward the closed position of the valve control, or when the stem has moved no more than one-fifth of the distance from its normal position.

               4.      The supervisory switch shall be contained in a weatherproof aluminum housing, which shall provide a 3/4 inch (19 mm) conduit entrance and incorporate the necessary facilities for attachment to the valves.

               5.      The switch housing shall be finished in red baked enamel.

               6.      The entire installed assembly shall be tamper proof and arranged to cause a switch operation if the housing cover is removed, or if the unit is removed from its mounting.

               7.      Valve supervisory switches shall be provided and connected under this section and installed by mechanical contractor.

        J.      Manual Release/Abort Station

               1.      Manual release/abort stations shall be non-code, non-breakglass type, equipped with key lock in order that they may be tested without operating the handle. 

               2.      Stations must be so designed that after an actual activation, they cannot be restored to normal except by key reset.

               3.      Stations shall include a momentary ("dead-man") switch that may be manually held in to cause abort of the release process.

        K.      Carbon Monoxide Detector

               1.      Carbon monoxide detector shall be a System Sensor model number CO1224, listed to Underwriters Laboratories UL 2075 for Gas and Vapor Detectors and

Sensors. 

               2.      The detector shall be equipped with a sounder and a trouble relay. 

               3.      The detector�s base shall be able to mount to a single-gang electrical box or direct (surface) mount to the wall or ceiling. Wiring connections shall be made by means of SEMS screws.

               4.      The detector shall provide dual color LED indication, which

blinks to indicate normal standby, alarm, or end-of-life. When the sensor supervision is in a trouble condition, the detector shall send a trouble signal to the panel. When the detector gives a trouble or end-of-life signal, the detector shall be replaced.

PART 3.0 - EXECUTION

3.1.    INSTALLATION:

        A.      Installation shall be in accordance with the NEC, NFPA 72, local and state codes, as shown on the drawings, and as recommended by the major equipment manufacturer.

        B.      All conduit, junction boxes, conduit supports and hangers shall be concealed in finished areas and may be exposed in unfinished areas. Smoke detectors shall not be installed prior to the system programming and test period. If construction is ongoing during this period, measures shall be taken to protect smoke detectors from contamination and physical damage.

        C.      All fire detection and alarm system devices, control panels and remote annunciators shall be flush mounted when located in finished areas and may be surface mounted when located in unfinished areas.

        D.      At the final inspection a factory trained representative of the manufacturer of the major equipment shall perform the tests in Section 3.2 TESTS.

3.2.    TEST:

        Provide the service of a competent, factory-trained engineer or technician authorized by the manufacturer of the fire alarm equipment to technically supervise and participate during all of the adjustments and tests for the system.

               1.      Before energizing the cables and wires, check for correct connections and test for short circuits, ground faults, continuity, and insulation.

               2.      Close each sprinkler system flow valve and verify proper supervisory alarm at the FACP.

               3.      Verify activation of all flow switches.

               4.      Open initiating device circuits and verify that the trouble signal actuates.

               5.      Open and short notification appliance circuits and verify that trouble signal actuates.

               6.      Ground device circuits and verify response of trouble signals.

               7.      Open release solenoids and verify response of trouble signals.

               8.      Check presence and audibility of tone at all alarm notification devices.

               9.      Check installation and supervision of heat detectors to ascertain that they will function as specified. 

               10.     Conduct tests to verify trouble indications for common mode failures, such as alternating current power failure.

               11.     Each of the alarm conditions that the system is required to detect should be introduced on the system. Verify the proper receipt and that the release solenoid(s) will activate.

3.3.    FINAL INSPECTION:

        At the final inspection a factory trained representative of the manufacturer of the major equipment shall demonstrate that the systems function properly in every respect.

3.4.    INSTRUCTION:

        Provide instruction as required to the building personnel. "Hands-on" demonstrations of the operation of all system components and the entire system shall be provided.
