which will silence the trouble buzzer, but will not extinguish the
trouble indicator LED/LCD. Subsequent trouble and supervisory alarms
shall sound the trouble signal until silenced. After the system
returns to normal operating conditions, the trouble buzzer shall again
sound until the silencing switch returns to normal position, unless
automatic trouble reset is provided.
d. A one person test mode. Activating an initiating device in this
mode will activate an alarm for a short period of time, then
automatically reset the alarm, without activating the transmitter
during the entire process.
e. A transmitter disconnect switch to allow testing and maintenance of
the system without activating the transmitter but providing a trouble
signal when disconnected and a restoration signal when reconnected.
f. Evacuation alarm silencing switch which, when activated, will
silence alarm devices, but will not affect the zone indicating LED/LCD
nor the operation of the transmitter. This switch shall be over-ridden
upon activation of a subsequent alarm from an unalarmed device and the
NAC devices will be activated.
g. Electrical supervision for circuits used for supervisory signal
services (i.e., sprinkler systems, valves, etc.). Supervision shall
detect any open, short, or ground.
h. Confirmation or verification of all smoke detectors. The control
panel shall interrupt the transmission of an alarm signal to the system
control panel for a factory preset period. This interruption period
shall be adjustable from 1 to 60 seconds and be factory set at [20]
[_____] seconds. Immediately following the interruption period, a
confirmation period shall be in effect during which time an alarm
signal, if present, will be sent immediately to the control panel.
Fire alarm devices other than smoke detectors shall be programmed
without confirmation or verification.
i. The fire alarm control panel shall provide supervised addressable
relays for HVAC shutdown. An override at the HVAC panel shall not be
provided.
j. Provide one person test mode - Activating an initiating device in
this mode will activate an alarm for a short period of time, then
automatically reset the alarm, without activating the transmitter
during the entire process.
k. The fire alarm control panel shall provide the required monitoring
and supervised control outputs needed to accomplish elevator recall.
l. The fire alarm control panel shall monitor [and control] the fire
sprinkler system, or other fire protection extinguishing system.
m. The control panel and field panels shall be software reprogrammable
to enable expansion or modification of the system without replacement
of hardware or firmware. Examples of required changes are: adding or
deleting devices or zones; changing system responses to particular
input signals; programming certain input signals to activate auxiliary
devices.
n.
Zones for [IDC] [and] [NAC] shall be [arranged as indicated on the
SECTION 13851A
