Testing And Maintenance - Bellman & Symfon BE1481 Manual Del Usuario

Locate away from very dusty or dirty
areas as dust build-up in the chamber
can make unit too sensitive and prone
to alarm. It can also block the insect
screen mesh and prevent smoke from
entering the chamber.

Testing and maintenance

Your smoke alarm is a life saving device and should be checked periodically. Regularly
check that the status indicator on the smoke alarms flashes once a minute to show the
units are powered. Replace the battery if the blinking stops.
Manually testing your smoke alarm
It is recommended that you test your smoke alarms after installation and then at least
weekly to ensure the units are working. It will also help you and your family to become
familiar with the sound of the alarms.
Press and hold the test button until the alarm sounds, see Installation. The alarm will

stop sounding shortly after the button is released.
If you are using a supplementary Visit receiver, check that the red Visit LED on the

receiver lights up and that it starts to sound, flash or vibrate depending on the receiv-
er. See Installation and the corresponding Visit receiver user manual.
The receiver will time out within 40 seconds.

Repeat this procedure for all other smoke alarms in the system.

Do not test with flame
This can set fire to the smoke alarm and damage the house. We do not recommend
testing with smoke as the results can be misleading unless special apparatus is used.
When you press the test button it simulates the effect of smoke in a smoke alarm
which it could experience in a real fire. So, there is no need to test smoke alarms with
smoke or flame.
20
Do not locate in insect infested areas.
Small insects getting in to the cham-
ber can cause intermittent alarms.
Nuisance alarms
If, when the alarm goes off, there is no sign of smoke, heat or noise to indicate that there is
a fire, you should first get your family into a safe place, before you start investigating.
Check the house carefully in case there is a small fire smouldering 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 so, simply fan the smoke away
with a newspaper or similar.
If the cause of the alarm is not clear, it should be assumed that it is due to an actual

fire and the dwelling should be evacuated immediately.
If there are frequent nuisance/false alarms it may be necessary to re-locate the smoke
alarm away from the source of the fumes. We recommend the use of a heat alarm in
the kitchen area to avoid such nuisance alarms.
Cleaning your smoke alarm
Clean your smoke alarm regularly. Use a soft bristle brush or the brush attachment of
your vacuum cleaner to remove dust and cobwebs from the sides and cover slots where the
smoke enters. Keep cover closed while cleaning.
Do not vacuum or brush inside the smoke alarm. Do not paint your smoke alarm.
Other than the maintenance and cleaning described in this leaflet, no other custom-
er servicing of this product is required. Repairs, when needed, must be performed by
the manufacturer.
Dust & insect contamination
All smoke alarms are prone to dust and insect ingress which can cause false alarms.
The latest design, materials and manufacturing techniques have been used in the
construction of our alarms to minimise the effects of contamination. However, it is
impossible to completely 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, contamination 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.
