external modems for remote programming and diagnostics shall be
accepted.
C. Provide a dual line digital communicator with battery back-up. Unit shall
be activated by fire alarm panel and shall signal an UL listed central station.
Wire the digital communicator line seizure to two (2) existing outside
(trunk) telephone lines. Coordinate system communication with local 911
Center providing point-to-point information of alarm.
2.1.14 Dry Contacts
A. The FACP shall have three (3) form “C” dry contacts, one (1) shall be
dedicated to trouble conditions, the other two (2) shall be programmable
for alarm, trouble, sprinkler supervisory, notification, pre-alarm, waterflow,
manual pull, zone aux. 1 or zone aux. 2. The trouble contact shall be
normal in an electrically energized state so that any total power loss (AC
and backup) shall cause a trouble condition. In the event that the
microprocessor on the FACP fails, the trouble contacts shall also indicate a
trouble condition.
2.1.15 Ground Fault Detection
A. There shall be a ground fault detection circuit to detect positive and
negative grounds on all field wiring. The ground fault detection shall
operate the general trouble devices as specified but shall not cause an alarm
to be sounded. Ground fault shall not interfere with the normal operation,
such as alarm, or other trouble conditions.
2.1.16 Overcurrent Protection
A. All low voltage circuits shall be protected by microprocessor controlled
power limiting or self restoring poly switches for the following: smoke
detector power, main power supply, indicating appliance circuits, battery
standby power and auxiliary output.
2.1.17 Test Functions
A. A Lamp Test mode shall be a standard feature of the fire alarm control
panel and shall test all LED’s and the LCD display on the main panel and
remote annunciators.
B. A Walk Test mode shall be a standard feature of the fire alarm control
panel. The walk test feature shall function so that each alarm input tested
shall operate the associated notification appliances for six seconds. The
FACP shall then automatically perform a reset operation and confirm
normal device operation. The event memory shall contain the information
on the point tested.
C. A Fire Drill mode shall allow the manual testing of the fire alarm system
notification circuits. The Fire Drill shall be capable of being controlled at
the main annunciator, remote annunciators and a remote contact input.
