8. Timing of Installing/Decorating
•
Install the base plate (and surface pattress if used) at 1st fix.
•
Do not install alarm until following trades have finished e.g.
plasterers/painters/carpet fitters etc..
•
Do not install alarms until property has stabilized at a habitable environment to
avoid alarm contamination.
•
Dust and other contaminants e.g. paint fumes, will enter the alarm causing possible
nuisance alarms and damage the sensitive components within.
•
Never plug in or remove cabling when circuit is live as you could short circuit it and
invalidate the guarantee.
•
After installation, cover the alarm with the supplied dust cover –
this must be
removed just prior to occupation for the alarm to function.
9. Decorating
•
Never paint the alarm.
•
During redecoration, all alarms should be covered with the supplied dust cover or a
plastic bag to prevent contamination by fumes. (These can permanently damage the
alarm).
Do not uncover until the surrounding paintwork is thoroughly dried
.
•
Whilst covered, the alarm
cannot
operate. Remove covering as detailed above.
10. L.E.D. Status
•
Green L.E.D. is lit when AC power is present.
•
Red L.E.D. blinks to indicate normal operation of alarm function. (If model with battery
back-up, also indicates healthy battery.) In alarm state (i.e. triggered), L.E.D. will flash
rapidly. When interconnected, only triggering alarm will have this state.
• If interconnected to other alarms only the triggering alarm will have a rapidly
flashing L.E.D..
• On optical alarms if the red L.E.D. blinks every 30-40 seconds and the alarm chirps in
between, it indicates failure of the sensing chamber. Householders should consult
Owner’s Manual or installer/landlord.
•
The alarm sounder and flashing L.E.D. will remain whilst the alarm continues to detect
smoke (or excessive heat in a heat alarm).
11. Ongoing Maintenance
•
Alarms are sensitive electrical devices. The test button should be pushed (and held)
once a week to verify operation.
•
Once a month the alarm should be wiped with a mildly damp cloth, having previously
vacuumed the outside of the unit, especially through the grill area.
The mains supply
should first be isolated
.
12. Battery Replacement
(AC models with loose battery only)
•
If the alarm type has replaceable battery cells,
they should be replaced annually. (If using alkaline,
this can be extended to 2 years).
•
A chirp once every 30 - 40 seconds indicates the
battery needs replacement. Do this as soon as possible.
•
Mains power should be disconnected at the
Consumer Unit/fuse box.
•
Insert screwdriver in slot indicated to release locking tab. Whilst inserted push alarm
hard with palm of hand in direction of arrow shown on alarm front.
•
Replace with an alkaline battery such as Duracell MN1604, Duracell Ultra MX1604;
Energizer 6LR61, (Do not use rechargeable cells.)
