When the panel successfully resets, ringback will cause the trouble buzzers on the detector cabinet and the
common signal device on the repeater cabinet to sound until the "SILENCE" switches are returned to their
"NORMAL" position.
6.9
Off-normal position of each "SILENCE" switch is visually indicated by an amber "ALARM SILENCE" lamp which is
illuminated by the operation of the "SILENCE" switch.

Each detector module continually supervises:
a.
Its own light source.
b.
The presence of lamp operating power.
c.
The continuity of wiring to fire lamp at the remote repeater cabinet (when used).
d.
The integrity of the lamp filament at the repeater cabinet (when used).
6.11
Failure of any one of the supervised items results in illumination of the trouble LED (amber) on the individual
module front.
6.12
Origination of trouble from any individual module causes the common "TROUBLE" lamp (amber) to illuminate and
the trouble buzzer and the common signal device to operate.
6.13
The trouble buzzer may be silenced by operating the "TROUBLE SILENCE" switch on the panel front.
6.14
At the repeater cabinet, the common trouble is illuminated and the common signal device operates.
6.15
The common signal device at the repeater cabinet is silenced by operating the "TROUBLE SILENCE" switch.
6.16
Off-normal position of the "TROUBLE SILENCE" switch is indicated by an amber "TROUBLE SILENCE" lamp.
6.17
Trouble signals are non-latching. When the condition causing the trouble is removed, the "TROUBLE" lamp on
the module front will go out.
6.18
Following the elimination of a trouble output from the module, the common "TROUBLE" lamp will be extinguished.
