6 Operation and Maintenance
Expected Result
● If the PWR
indicator is steady
green, the power
input is normal.
● The RUN
indicator blinks at
long intervals,
indicating that
the device is
running properly.
● The ALM
indicator is off.
The indicator blinks
once every 6
seconds. (The
interval varies with
detectors. See the
product
instructions.)
Troubleshooting
● If the PWR
indicator is off,
check whether
the 48 V power
cable and
connectors are
normal. If not,
reconnect them. If
so, replace them.
● If the RUN
indicator blinks at
short intervals,
check whether
the
communications
cable is loose or
disconnected. If
so, reconnect the
cable.
● If the ALM
indicator is steady
on, check and
rectify alarms.
If the indicator blinks
twice every 6
seconds or does not
blink, the smoke
detector is faulty or
the cables are not
properly connected.
Check the cables or
replace the smoke
detector.
