4 Routine Maintenance
Troubleshooting
 If the RUN indicator blinks at short
intervals, check whether the
communications cable is loose or
disconnected. If so, reconnect the
cable. If not, replace the cable.
 If the ALM indicator is steady on, clear
the alarm.
 If the RUN indicator is off, check the
communications cable. If the RUN
indicator blinks at short intervals and
the communication is interrupted,
restart WiFi converter.

Check whether the mobile phone and
pad are normal. If not, check whether
the antenna is shielded. If so, install the
antenna to a different position. If not,
replace the WiFi antenna.
 If the PWR indicator is off, check
whether the communications cable is
loose or disconnected or whether the
smart ETH gateway is not energized. If
so, reconnect the cable. If not, replace
the cable.
 If the RUN indicator blinks at short
intervals, check the communications
cable connection. If the fault persists,
replace the multi-functional sensor.

If the ALM indicator is steady on, clear
the alarm.
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.
 If the PWR indicator is off, check
whether the communications cable is
loose or disconnected or whether the
smart ETH gateway is not energized. If
so, reconnect the cable. If not, replace
the cable.

If the RUN indicator blinks at short
intervals, check whether the
communications cable is loose or
disconnected or whether the smart
ETH gateway is energized.

If the ALM indicator is steady on, clear
the alarm.
