the effects of contamination. However it is impossible to com- pletely eliminate the effect of dust and insect contamination, and therefore, to prolong the life of the Smoke Alarm you must ensure that it is kept clean so that excess dust does not build up. Any insects or cobwebs in the vicinity of the Smoke Alarm should be promptly removed.
In certain circumstances even with regular cleaning, contam- ination can build up in the smoke sensing chamber causing the alarm to sound. If this happens the alarm must be returned for servicing or replacement. Contamination is beyond our control, it is totally unpredictable and is consid- ered normal wear and tear. For this reason, contamination is not covered by the guarantee and a charge is made for all such servicing work.
7.7 Replacing the Battery
A fresh Alkaline Battery should last for over a year. When the battery power is low and replacement is necessary, the Alarm will “beep” and the red light will flash at the same time about once per minute for at least 30 days. The battery must then be replaced. Also, replace the battery if the alarm does not sound when the Test Button is pressed. For maximum relia- bility, replace the battery at least once a year. When you replace the battery you must press the test button to check that the alarm is functioning okay.
Do not put the Smoke Alarm into a fire.
8.TROUBLESHOOTING YOUR ALARMS
8.1Alarms sounds for no apparent reason
•House code your alarms (see section 6). If the alarms are in the default factory settings, neighbouring units may cause them to alarm.
•Check for fumes, steam, etc. from kitchen or bathroom. Paint and other fumes can cause nuisance alarms.
•Check for any sign of contamination such as cobwebs or dust. Clean the alarm as described in section 7.4 if neces- sary.
•On Ei3105RF units press the test/hush button on the unit causing the alarm (this can be identified as the alarm with the red light flashing rapidly) – this will silence the smoke alarm for 10 minutes and also silence all other smoke alarms in the system.
8.2The alarm fails to sound when the test button is pressed
•Check the age of the unit - see the “replace by” label on base of unit.
•Check the battery snaps are firmly connected on the unit.
