(3) RF receiver malfunction

 

 

(4) Indication of automatic switchover

20.

Emergency Communications Equipment

 

 

 (a) Amplifier/tone generators

Correct switching and operation of backup equipment shall be verified.

 

 (b) Call-in signal silence

Function shall be operated and receipt of correct visual and audible signals at control unit shall be verified.

 

 (c) Off-hook indicator (ring down)

Phone set shall be installed or phone shall be removed from hook and receipt of signal at control unit shall be verified.

 

 (d) Phone jacks

Phone jack shall be visually inspected and communications path through jack shall be initiated.

 

 (e) Phone set

Each phone set shall be activated and correct operation shall be verified.

 

 (f) System performance

System shall be operated with a minimum of any five handsets simultaneously. Voice quality and clarity shall be verified.

21.

Combination Systems

 

 

(a) Fire extinguisher monitoring device/system

Communication between the device connecting the fire extinguisher monitoring device/system and the fire alarm control unit shall be tested to ensure proper signals are received at the FACU and remote annunciator (s) if applicable.

 

(b) Carbon monoxide detectors

Functional tests shall be conducted according to manufacturer’s published instructions.

22.

Interface Equipment

Interface equipment connections shall be tested by operating or simulating the equipment being supervised. Signals required to be transmitted shall be verified at the control unit. Test frequency for interface equipment shall be the same as the frequency required by the applicable NFPA standard(s) for the equipment being supervised.

23.

Fire Safety Functions

Fire safety functions (i.e., fan control, smoke damper operation, elevator recall, elevator power shutdown, door holder release, door unlocking, etc.) shall be tested by operating or simulating alarm signals. Testing frequency for fire safety functions shall be the same as the frequency required for the initiating device that activates the fire safety function.

24.

Guard’s Tour Equipment

The device shall be tested in accordance with the manufacturer’s published instructions.

25.

Special Procedures

 

 

 (a) Alarm verification

Time delay and alarm response for smoke detector circuits identified as having alarm verification shall be verified.

 

 (b) Multiplex systems

Communications between sending and receiving units under both primary and secondary power shall be verified.

 

 

Communications between sending and receiving units under open circuit and short circuit trouble conditions shall be verified.

 

 

Communications between sending and receiving units in all directions where multiple communications pathways are provided shall be verified.

 

 

If redundant central control equipment is provided, switchover and all required functions and operations of secondary control equipment shall be verified.

 

 

All system functions and features shall be verified in accordance with manufacturer’s published instructions.

26.

Low-Power Radio (Wireless Systems)

The following procedures describe additional acceptance and reacceptance test methods to verify wireless protection system operation:

 

 

(1) The manufacturer’s published instructions and the as-built drawings provided by the system supplier shall be used to verify correct operation after the initial testing phase has been performed by the supplier or by the supplier’s designated representative.

 

 

(2) Starting from the functional operating condition, the system shall be initialized in accordance with the manufacturer’s published instructions. A test shall be conducted to verify the alternative path, or paths, by turning off or disconnecting the primary wireless repeater. The alternative communications path shall exist between the wireless control unit and peripheral devices used to establish initiation, indication, control, and annunciation. The system shall be tested for both alarm and trouble conditions.

 

 

(3) Batteries for all components in the system shall be checked monthly. If the control unit checks all batteries and all components daily, the system shall not require monthly testing of the batteries.

aExample: 4000 mAh × = 160 mA charging current at 25°C (77°F).

bThe voltmeter sensitivity has been changed from 1000 ohms per volt to 100 ohms per volt so that false ground readings (caused by induced voltages) are minimized.

cFusible thermal link detectors are commonly used to close fire doors and fire dampers. They are actuated by the presence of external heat, which causes a solder element in the link to fuse, or by an electric thermal device, which, when energized, generates heat within the body of the link, causing the link to fuse and separate.

      dFor example, it may not be possible to individually test the heat sensor in a thermally enhanced smoke detector.
