Troubleshooting
 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
