TROUBLESHOOTING
1. FREQUENT NUISANCE ALARMS OCCUR:
(1) Close kitchen / bathroom door when in use.
(2) Ensure that the alarm is sited at least 6m away from sources
of fumes.
(3) Contamination from insects, paint or paint fumes may have
occurred. Clean the alarm - see page 5.
(4) If the problem persists, resiting of the unit should be consid-
ered.
2. ALARM SOUNDS FOR NO APPARENT REASON:
(1) Identify the alarm source. On interconnected units, the red
light on the cover will flash rapidly only on the unit which is the
source of the alarm.
(2) Check for fumes, steam etc. from the kitchen or bathroom.
Paint and other fumes can cause nuisance alarms.
(3) Press the test/hush button to silence the Smoke/Heat Alarm
for 10 minutes.
(4) If alarm does not stop, switch off mains and remove unit (see
figure 1). (Only remove alarm with red light flashing, the oth-
ers are probably satisfactory).
3. LOW BATTERY & OTHER BEEPS:
(On EIi144/146 only)
If the battery is correctly connected and the unit has beeped for
over 20 minutes the battery is probably depleted. Obtain a new
battery, disconnect the mains, then remove the alarm and replace
the depleted battery.
(On Ei164/166 only)
Check the green mains power light is on. If not, check fuse, circuit
breakers and wiring connections. If the green light is off, the lithium
cells will deplete after some months without mains and will need to
be recharged. If the above fails to turn on the green light, a fault
may exist. Switch off mains and remove the unit (see figure 1).
(All Alarms)
(1) If the green mains light is on and replacing battery, recharging
lithium cells or cleaning unit has not stopped beeps, a fault
may exist. Disconnect the mains first and replace the unit
(see figure 1).
(2) The Ionisation units Ei140/161) give two beeps 10 minutes af-
ter the test//hush button is pressed.
(3) If the Optical units Ei 146/145/166) beeps without the red light
flashing at the same time, the chamber is defective. Clean the
chamber.
