SMOKE & HEAT ALARMS

Maintenance
We recommend weekly testing by pressing the test button on the
alarm/s for between 5 - 10 seconds, or until all interconnected
alarms sound. The use of a low level System Control Switch sited at
low level can be used to make this easier for the occupier.
BS 5839: Pt.6: 2004 recommends that a smoke/heat test is preformed
when the system is commissioned. Pressing the test button checks
the electronics, interconnect and the horn are operational, so it is
our view that it is not necessary to test with smoke or heat and a
‘variation’ can be invoked in order to comply with the standard.
However, if it is considered that testing of smoke alarms is a necessity,
we would only recommend the use of special purpose built
equipment such as the SAT332 Smoke Alarm Tester with the SAA300
Synthetic Smoke Aerosol. This device ensures that sufficient synthetic
”smoke” enters the sensor chamber and remains long enough for
the Smoke Alarm to respond. Other methods of smoke testing, e.g. a
lighted taper or smoke pellets, can give misleading results. Testers for
Heat Alarms are also available. Do Not test with a flame - this can
be a hazard in itself.
The Ei range of Smoke and Heat Alarms are suitable for use in
Grades D, E and F systems as defined in the British Standard which
covers alarm systems in domestic dwellings, BS 5839: Pt6: 2004 It
states that these alarms “should be cleaned periodically in
accordance with the manufacturers instructions”.
Our recommendations are as follows:
- Regularly check to see that the green mains power light is on.
- Press the test button weekly to check all alarms in the system.
- Regularly check that the red light under the test button or on
the cover flashes approx. every 40 seconds.
- Clean the cover of the alarm regularly using a barely damp,
lint free cloth.
- On a monthly basis (at least) check the alarm for signs of
contamination from dust, cobwebs or insects. Use a vacuum
cleaner around the cover of the alarm to remove contamination.
- Check (at least annually) that the alarm will operate on back-up
battery power only by switching off the mains supply and pressing
the test button.
