occur.
See section 5 (if the hush button has been pressed
the unit will chirp for 7 minutes to indicate it is in
hush mode).
See parts 1a and 1b above. Have installer re check
wiring if Green LED is illuminated, but alarm does
not appear to function. If no Green LED check con-
sumer unit. Alarm with still function on battery
power, if battery is in serviceable state. <Red LED
will blink about once a minute to confirm>. Check
via Test Button.
See part 1b above – consult a qualified electrician or
your Landlord to remedy as soon as possible.
11. Battery Replacement
(AC models with loose battery only)
• If the alarm type has replaceable battery cells, they should be replaced annual-
ly. (If using alkaline, this can be extended to 2 years).
• A chirp once every 40 seconds indicates the battery needs replacement. Do
this as soon as possible.
• Mains power should be disconnected at the Consumer Unit/fuse box.
•
See section 4 to see how to remove alarm and locate battery draw
.
• Replace with an alkaline battery such as Duracell MN1604, Duracell Ultra
MX1604. Energizer 6LR61, Gold Peak 1604A; Lithium type: Ultralife U9VL.
(Do not use rechargeable cells.)
•
If a chirping noise is present after this, wait for 10 minutes to elapse, as it may
be due to the hush button having been pushed
.
On Long Life and rechargeable models there are no user replaceable components.
12. Repair/Servicing
• If the alarm is not functioning, first check the troubleshooting section. If this
does not rectify the problem:
• Consult your installer wholesale distributor or landlord for advice if property is
rented.
• There are no user serviceable parts, except for models with loose batteries.
•
Do not attempt to dismantle the alarm – this will invalidate the guarantee
.
13. Troubleshooting
• Always turn off the mains supply to AC alarms before checking connections etc..
