Nuisance Alarms; Important Safeguards - Ei Electronics Ei181 Instructions Manual

NUISANCE ALARMS

If there is a nuisance alarm simply press the test/hush
button on the Alarm to silence the unit for 10 minutes.
If, when the alarm goes off, there is no sign of smoke, heat
or noise to indicate that there is a fire, you should get your
family into a safe place, before you start investigating.
Check the house carefully in case there is a small fire
smould- ering somewhere.
Check whether there is some source of smoke or fumes, for
example cooking fumes being drawn past the Smoke Alarm
by an extractor.
If there are frequent nuisance/false alarms it may be
necessary to re-locate the device away from the source of
the fumes. If for some reason the alarm continues to sound
without smoke or heat being present (due to insect infestation
or contamination build-up for example) the units can be
silenced by disconnecting the panel power and removing the
unit (see figure 1). If cleaning the Alarm does not correct the
problem it can be returned to the manufacturer for repair or
replacement (see Getting Your Alarm Serviced below).
Hush Feature
All the Smoke / Heat Alarms have a combined Test/Hush
Button to help you control nuisance false alarms.
1. To cancel a false alarm, press the Test/Hush Button
located on the cover. The Alarm will automatically switch to
a reduced sensitivity condition (very large levels of smoke
from a nearby fire will override the Hush on the smoke
alarms). This condition allows unwanted alarms to be
silenced for a period of approximately 10 minutes.
The unit will flash the red light every 10 seconds
(instead of the normal 40 seconds) to indicate the
sensitivity is reduced. At the end of the hush period the
Ionisation Smoke Alarm (Ei181) and the Heat Alarms
(Ei184) will give two short beeps. The Optical Smoke
Alarm (Ei186) does not give these two beeps.
On interconnected Alarms, pressing the Test/Hush Button
on the one sensing smoke (i.e. the one with the red light
flashing every second) will silence all alarms. Pressing the
Hush Button on any other Alarm will not cancel the alarm.
2. The unit will reset to normal sensitivity at the end of the
silenced period. If additional silenced time is required,
simply push the Test/Hush Button again.
IMPORTANT SAFE GUARDS
• When using household protective devices, basic safety
precautions should always be followed, including those
listed below:
• Please read all instructions.
• Rehearse emergency escape plans so everyone at home
knows what to do in case the alarm sounds. Further
information can be obtained from the Home Office
Publication entitled "Smoke Detectors in the Home" (FB2)
or from your local fire prevention officer.
