voyage, the blower motors can be shut down manually by removing fuse No. 6 for a forty (40) second period
twice a day or for one eighty (80) second period once a day (the latter will cause a trouble signal near the end).
In the event the condensate drain switch fails to an off condition, the suction blower failure trouble signal will occur
approximately one minute after the initial stopping of the blowers.
NOTE
This failure mode has a delayed operation to prevent nuisance trouble signals
during the daily interruption of blower operation.

Supervision of Repeater
The detecting cabinet provides continuous supervision of the significant connections between the detector cabinet
and the remote repeater cabinet, including filament supervision of the common smoke lamp and all smoke alarm
lamps on the repeater cabinet.
Loss of continuity between the main detector cabinet and the remote repeater cabinet produces a signal on the
"Remote Smoke Lamp" LED on the electronics drawer front as well as a common trouble signal from the panel.
7.19
Day/Night Switch
A day/night switch is provided on the detector cabinet for night navigation. This permits the dimming of the
power-on indicator and the blanking of the digital readout during the night operation (the decimal point which
indicates the operation of the timer is not dimmed in night operation).
7.20
Reset Switch
Consistent with current alarm system practice, the smoke alarm signal at the individual line module and common
panel indication latches. This signal is cancelled by the operation of the reset switch:
1.
NOTE:
Reset is not possible while any smoke remains in a line detector module.
2.
Reset will only take place approximately five minutes after elimination of the last traces of smoke from any
line detector module.
