or low battery voltage shall result in the operation of the system trouble
signals. The abnormal position of any system switch in the control panel
shall result in the operation of the system trouble signals. Trouble
signals shall operate continuously until the system has been restored to
normal at the control panel. [Provide a 100 mm 4 inch remote system
trouble bell [or buzzer], installed [in a constantly attended area] [where
shown], arranged to operate in conjunction with the integral trouble
signals of the panel. Provide remote bell [or buzzer] with a rigid plastic
or metal identification sign which reads "FOAM SYSTEM TROUBLE." Lettering
on identification sign shall be a minimum of 25 mm one inch high.] Control
panel, batteries, and battery charger shall be weatherproof type or located
in an area not subject to water damage. System control panel shall be UL
listed or FM approved for extinguishing system control (releasing device
service). [Control panel initiating circuits shall be intrinsically safe
for use with line-type heat detection systems.] Permanently label all
switches. Provide panel with the following switches:
a.
Trouble silencing switch which transfers audible trouble signals
(including remote trouble devices, if provided) to an indicating
lamp. Upon correction of the trouble condition, audible signals
will again sound until the switch is returned to its normal
position, or the trouble signal circuit shall be automatically
restored to normal upon correction of the trouble condition. The
silencing switch may be a momentary action, self-resetting type.
b.
Alarm silencing switch which when activated will silence all
associated alarm devices without resetting the panel, and cause
operation of system trouble signals.
c.
Individual zone disconnect switches which when operated will
disable only their respective initiating circuit and cause
operation of the system and zone trouble signals.
d.
Reset switch which when activated will restore the system to
normal standby status after the cause of the alarm has been
corrected, and all activated initiating devices reset.
e.
Lamp test switch.
[f.
City disconnect switch which when activated will disconnect the
coded device and cause operation of the system trouble signal.]
2.3.1.1
Main Annunciator
Provide integral with the main control panel. Provide separate alarm and
trouble lamps for each zone alarm initiating circuit as indicated below,
located on the exterior of the cabinet door or visible through the cabinet
door. Lamps shall be LED (Light Emitting Diode) type. Supervision will
not be required provided a fault in the annunciator circuits results only
in loss of annunciation and will not affect the normal functional operation
of the remainder of the system. Each lamp shall provide specific
identification of the [zone] [area] [device] by means of a permanent label.
In no case shall zone identification consist of the words "Zone 1," "Zone
2," etc., but shall consist of the description of the [zone] [area]
[device].
