PART 2 PRODUCTS 2.1 SYSTEM DESIGN 2.1.1 Operation NOTE: Shutdown of mechanical (HVAC) systems must be carefully coordinated between this section and mechanical sections. The designer must choose whether to shut down all HVAC systems upon operation of the alarm system or to shut down individual HVAC units separately when smoke is detected in each unit's ductwork. Shutdown of all HVAC systems upon any alarm is desirable from a life safety standpoint, but may not be practical in all cases. Consult with the EFA/EFD Fire Protection Engineer for guidance. To shut down all HVAC units from the fire alarm control panel retain the reference to HVAC equipment shutdown in paragraph titled "Operation" and delete reference to shutdown in paragraph titled "Duct Smoke Detectors". If it is desired to shutdown systems on an individual unit basis, delete the reference to HVAC equipment shutdown in paragraph titled "Operation", and retain the reference to shutdown in paragraph titled "Duct Smoke Detectors". Provide a complete, electrically supervised, code 3 temporal common coded, manual [and automatic,] zoned, annunciated, _{fire alarm system} as described herein, and as shown on the drawings.

Battery power supply (low and no voltage across the standby battery terminals and open battery circuit). d. [Radio] [Master box] [Auxiliary transmitter] tripping circuits. Provide [Class B] [Class A] initiating device circuits, and [Class B] [Class A] notification appliance circuits as defined by NFPA 72. [For Class A circuits, provide separate conduits for outgoing and return (redundant) conductors as required by NFPA 72.] A ground fault condition or single break in any other circuit shall cause operation of the system trouble signals. Loss of AC power, abnormal AC voltage, a break in the standby battery power circuit, or low battery voltage shall also cause operation of system trouble signals. The abnormal position of any switch in the control panel shall also cause operation of the system trouble signals. Audible and visual equipment for supervision of the AC power supply shall be energized from the auxiliary DC power supply and vice versa. Trouble signals shall sound continuously until manually silenced or the system has been restored to normal. [Electrical monitoring for integrity of wiring external of control panel for mechanical equipment shut down and magnetic door holding circuits is not required, provided a break in the circuit will cause doors to close and mechanical equipment to shutdown.] [2.1.1.4 Walk-Test Mode Provide system with walk-test mode to allow one person to test alarm and supervisory features of initiating devices. Walk-test mode shall be enabled from the control panel by authorized service personnel. Control panel shall display a unique visual indication when system is in walk-test mode. If testing ceases while in walk-test mode, after a preset delay system shall automatically return to normal standby mode. ][2.1.1.5 Alarm Verification Feature NOTE: Consult with the EFD/EFA Fire Protection Engineer before specifying an Alarm Verification Feature (AVF). Currently, AVF is not compatible with 4-wire open-area (spot-type) smoke detectors. When AVF is specified, the 2-wire smoke detector option must be included in the paragraph titled "Open Area (Spot-Type) Smoke Detector." Do not specify AVF for duct smoke detectors. System shall have a smoke detector alarm verification feature. Upon activation of any area smoke detector, system shall institute an alarm verification process prior to enabling of the alarm functions as specified herein. Activation of any initiating device other than an area smoke detector shall cause immediate enabling of system into alarm mode. If an alarm input from a smoke detector on the initial zone in alarm is present at the end of an initial delay period not exceeding 20 seconds, all alarm functions as specified herein shall be immediately enabled. If a smoke detector alarm input is not present at the end of the initial delay period, a second-stage confirmation period of one minute shall be initiated. If a smoke detector alarm input is received during the second-stage confirmation period, all alarm functions shall be immediately enabled. During the verification process, activation of any area smoke detector on any zone other than the initial zone in alarm shall also cause system to go into alarm mode immediately. If no smoke detector alarm input occurs within the second-stage confirmation period, system shall reset to normal. Any alarm input received from an area smoke detector after the second-stage confirmation period has elapsed shall cause system to institute a new verification process. ][2.1.1.6 Elevator Recall NOTE: Delete this paragraph if no elevator work is included in the project. Provide elevator recall system in accordance with ASME A17.1, Section [14 21 00.00 20 ELECTRICAL TRACTION ELEVATORS] [14 24 00 HYDRAULIC ELEVATORS], and as specified herein. Activation of any smoke detector in an elevator shaft, machine room, or lobby (except at designated recall level) shall cause all elevators associated with that shaft, machine room, or lobby to return nonstop to the designated level. Activation of a smoke detector in the lobby or machine room at the designated level shall cause all elevators associated with that lobby to return nonstop to the assigned alternate level. Activation of a detector in an elevator shaft, machine room, or lobby shall also cause complete operation of fire alarm system as specified in paragraph titled "Operation". ]2.1.2 Primary Power NOTE: Consult with the EFD/EFA for guidance on use of safety switch.

Electrical metallic tubing shall not be installed in exterior or wet locations and shall not be imbedded in masonry or concrete. Provide a written schedule of conductor markings identifying each wire marker, the purpose, the origin, and termination point of each conductor. The _{conductor wire marker schedule} shall be turned over to the Contracting Officer at the time of preliminary testing with as built drawings. [3.1.1 Additional Installation Requirements NOTE: Include this paragraph in projects administered by SOUTHNAVFACENGCOM. Pull all conductors splice free. Make all conductor connections under screw terminals. Provide insulated barrier type terminal strips at junction points. Use of wire nuts, crimped connectors, or twisting of conductors is prohibited. All control panels shall be dressed out in a professional manner with all wires running in the vertical or horizontal plane, cut to exact length, making all turns at 90 degree angles, and tightly bundled and wire wrapped. Conduit may not enter the top of control panel cabinet. Provide panel in the manufacturer's NEMA 4 enclosure for panels subject to water spray/runoff and/or located in damp/dirty locations or relocate to a suitable dry location at the direction of the Contracting Officer. Provide conduit seals for all raceway terminating at the control panel cabinet. ]3.2 FIELD QUALITY CONTROL 3.2.1 _{Preliminary Testing} Notify Contracting Officer prior to performing preliminary testing. Contractor shall conduct the following tests during installation of wiring and system components. Any deficiency pertaining to these requirements shall be corrected by the Contractor prior to final acceptance testing of the system. Record results of testing. Submit all test results to the Contracting Officer. NOTE: Delete the first testing method for projects administered by SOUTHNAVFACENGCOM. a. Ground Resistance: [Prior to connecting control panel [and transmitter], test grounds for ground resistance value. Use a portable ground testing megger to test each ground or group of grounds. Make ground resistance measurements in normally dry weather, not less than 48 hours after a rainfall. Follow the directions provided by the equipment manufacturer for proper use of the equipment.] [Measure resistance of each connection to ground.] Resistance of each connection to ground shall not exceed 10 ohms. b. Operation of Entire System. Operate all initiating and indicating devices. c. Operation of Supervisory Systems: Operate all portions to demonstrate correctness of installation. NOTE: Include the bracketed text for sensitivity testing when 2-wire smoke detectors are specified. d. Smoke Detector Test: Clean the smoke detectors in accordance with the manufacturer's recommended procedures. Test smoke detectors using magnet-activated test switch, manufacturer-provided test card, or smoke. Use of aerosol sprays to test smoke detectors is prohibited. [When 2-wire smoke detectors are provided, prior to formal inspection and tests, perform sensitivity tests on each smoke detector. Perform voltage activation sensitivity test on each detector and record the results. Remove detectors with a sensitivity level above or below the UL accepted sensitivity range for that detector and replace with new detectors having the UL accepted sensitivity range. Present recorded data at the formal inspection for verification. Approved copies shall become part of the operation and maintenance manual for the fire alarm system.] [e. Duct Detector Differential Pressure Test: Measure and record the observed differential pressure between sampling tubes with completed HVAC system operating normally to verify airflow requirements through detector housing. Perform test on smoke detector heads as specified above for smoke detectors.] 3.2.2 _{Final Acceptance Testing} The Contractor shall notify the Contracting Officer when the system is ready for final acceptance testing. Request scheduling for final acceptance testing only after all necessary preliminary tests have been made and all deficiencies found have been corrected to the satisfaction of the equipment manufacturer's technical representative and the Contracting Officer, and written certification to this effect has been received by the [EFD] [EFA] Fire Protection Engineer. The system shall be in service at least 15 calendar days prior to final acceptance testing. The Contractor shall allow at least [15] [_____] calendar days between the date final testing is requested and the date the final acceptance testing takes place. The Contractor shall furnish all appliances, equipment, instruments, devices and personnel for this test. Furnish a minimum of three two-way radios plus one additional radio for each remote annunciator, all operating on the same frequency. The system shall be tested for approval in the presence of representatives of the manufacturer, the Contracting Officer, and the [EFD] [EFA] Fire Protection Engineer. All necessary tests shall be made including the following, and any deficiency found shall be corrected and the system retested. 3.2.2.1 Entire System Test the entire system by operating all fire alarm initiating, notification, and signaling devices. Perform tests with the system operating on primary power and repeat the test with the system operating on battery power only. Provide necessary equipment to test smoke detectors and heat detectors. 3.2.2.2 Supervisory Systems All aspects of the supervisory functions of the systems shall be operated. Introduce faults in each circuit at random locations as directed by the [EFD] [EFA] Fire Protection Engineer. Verify proper trouble annunciation at the control panel. 3.2.3 Additional Tests When deficiencies, defects or malfunctions develop during the tests required, all further testing of the system shall be suspended until proper adjustments, corrections or revisions have been made to assure proper performance of the system. If these revisions require more than a nominal delay, the Contracting Officer shall be notified when the additional work has been completed, to arrange a new inspection and test of the fire alarm system. All tests required shall be repeated prior to final acceptance, unless directed otherwise.
