Trouble Operation
Zone Troubles
For a status change into a trouble condition (open circuit) on a supervised alarm zone input (1-4):
The trouble LED for that alarm zone input illuminates.
The common trouble relay energizes and the trouble contact active LED illuminates.
The audible device sounds the steady trouble signal.
The programmed (or default) trouble event code is transferred to the SIA transmitter. (see dialing
operation)
For a status change into an off-normal condition on either the AC failure (zone 5), low battery (zone 6), or
no/missing battery (zone 7) zone inputs:
The power fault LED illuminates.
The common trouble relay energizes and the trouble contact active LED illuminates.
The audible device sounds the steady trouble signal.
The programmed (or default) power monitor event code is transferred to the SIA transmitter. (see
dialing operation)
If User Jumper J8 is installed, then an off-normal status change on the AC failure zone 5 will illuminate
the power fault LED, but the trouble relay, local audible, and the AC Power Failure transmission are
delayed for 2 hours. If zone 5 restores to normal before the 2 hours elapses, the pending AC Power
Failure transmission and the Restore transmission are cancelled. If zone 5 restores to normal after the 2
hour delay, i.e. after the AC Power Failure has been transmitted, then the Restore is transmitted without
delay. (Refer to Programming features table on page 33)
Note that the normal condition (normally open or normally closed) for zones 5, 6, and 7 is determined by
user jumpers 5, 6, and 7 respectively.
The silence pushbutton may be used to silence the audible. The audible will automatically resound for
zone troubles in 24 hours if the trouble condition is still present. Zone troubles are not latching, in that no
user intervention is required to enable subsequent status change reports if, for example, the zone
restores
to normal.
