12. Walk test<br />

13. Check system on battery voltage and current<br />

E. The fire alarm control panel shall be capable of alarm verification. The control panel shall<br />

indicate which smoke detector is in alarm during the pre-alarm window.<br />

F. All alarm signals shall be locked in at the panel until the operated device is returned to it's<br />

normal condition and the control panel is manually reset.<br />

G. Alarm or trouble activation of initiating points shall be represented in English on the<br />

alphanumeric display on both the remote operating panel and the fire alarm control panel<br />

indicating the address of the specific device, i.e. Device L4S76, Smoke Detector, 1st floor<br />

Rm. 17.<br />

H. Each initiating and signal circuit shall be electrically supervised for opens, shorts, and ground<br />

faults in the wiring.<br />

I. The occurrence of any fault shall activate the system trouble circuitry but shall not interfere<br />

with the proper operation of any circuit that does not have a fault condition.<br />

J. The system communication loops shall be capable of being wired using Class "A" (Style 6)<br />

supervised circuits (a ground fault on either conductor or a break shall not prevent a device<br />

from operating on either side of the break)<br />

K. The fire alarm control panel shall contain circuitry permitting the transmission of trouble and<br />

alarm signals over leased phone lines by the means of reverse polarity. There shall be a<br />

supervised disconnect switch to allow testing of the fire alarm control panel without<br />

transmitting an alarm to the central station.<br />

L. The fire alarm control panel shall include the following features.<br />

1. Auxiliary SPDT alarm actuated contacts.<br />

2. Auxiliary SPDT trouble actuated contacts.<br />

3. Auxiliary SPDT supervisory actuated contacts.<br />

4. A solid-state power transfer circuit that shall switch to standby power<br />

automatically and instantaneously if normal power fails or falls below<br />

15% of normal ("brown out" conditions). This electronic circuit shall allow<br />

the batteries to be effectively "floated" on the operating system to avoid<br />

upsetting the normal microprocessor scan and minimize resultant<br />

nuisance troubles and/or alarms.<br />

5. A ground fault detector to detect positive or negative grounds on the<br />

initiating circuits, signal circuits, power circuits, and telephone line circuit.<br />

A ground fault code on the alphanumeric display shall provide indication<br />

of either a positive or negative ground fault and shall operate a general<br />

trouble but shall not cause an alarm to be sounded.<br />

6. A short circuit error message shall be a standard feature of the fire alarm<br />

control panel. Each communication loop shall be monitored and shall<br />

have a distinctive error message.<br />
