WARNING:
Ensure the power supplies are turned off before installing
smoke detectors.
1. Using the fixings supplied attach the base plate of the smoke detector to
the desired position.
2. Connect the supply wires to the connectors – Brown to Live (L), Grey to
neutral (N) and the Black to Interlink (I). Be sure to sleeve the bare earth
wire and terminate it in the connector shown above.
3. 7885653303 versions only – Fit batteries in accordance with section
“Changing the Batteries” below.
4. Close the smoke detector making sure the 3 retaining clips are fitting
securely. When removing the smoke detector from it’s base-plate, use
a small flat bladed screwdriver in the slots to push away the clips and
lever the smoke detector away.
5. Test the smoke detector using the large test button (shown above) without
mains power and check it sounds at least 3 times and that the red LED
flashes.
6. Turn on the mains power supply. (7885653316 versions only – the
alarm may beep once every minute for around an hour while the battery
charge is topped up).
7. Check that the Green LED is on and that the red LED flashes once every
minute.
8. Test the smoke detector to check that all other interlinked smoke detectors
in the system sound. The LEDS on the other smoke detector will not flash
repeatedly during this operation.
IMPORTANT NOTE:
Use only the test button to test the smoke detector
weekly. Do not test the smoke detector with either a naked flame or smoke,
this will damage and contaminate the smoke detector causing nuisance
alarms in the future.
6. USER INFORMATION
Protect your home against fire
Make sure all occupants of the home know what a fire alarm sounds like.
Prove and practise a fire escape plan and arrange a suitable and safe
assembly point.

smoke and fire
Repeating series of 3 beeps every

··· ··· ··· ···

·· ·· ·· ··
If the full alarm sounds, ensure everyone leaves the building as soon as possible.
• Do not run.
• Do not stop to collect belongings.
• If it is safe to do so, close all windows and doors as you escape to prevent
the spread of fire.
• Smoke is the main cause of death from fire. If trapped inside the building,
cover your mouth, conserve breath and crawl to safety.
Do not silence a smoke detector until you know the cause of the alarm and
when all occupants are safely outside the building. The red LED on the test but-
ton of the smoke detector that has set the system off will be flashing Red once
every second. The lights on the other smoke detectors will be flashing once
every minute. The system can only be silenced from this smoke detector.
7. CHANGING THE BATTERIES
CAUTION!
Danger of explosion if the battery is incorrectly replaced. Replace
only with correct batteries
The smoke detector will emit an acoustic signal once a minute to indicate the
batteries need replacing. If this happens at night press the test button to silence
the warning for 10 hours and replace the following day.
In the event of a low battery warning on the 7885653316 replace the alarm.
The battery is not replaceable.
Replacing batteries (7885653303 only)
To replace the batteries on the 7885653303 version, isolate mains power to
the smoke detector, release the retaining clips, lower the smoke detector on its
hinge and refer to Fig. 2.
Insert the three AAA-batteries. Ensure the new batteries are installed correctly
and close the detector. Mount the detector correctly, reconnect the power and
test the detector.
Maintenance of the smoke detector
A regular smoke detector maintenance is advised to ensure the detector
always works properly.
• Test the smoke detector once a week. All linked detectors should sound
within 10 seconds.
• Vacuum the smoke detector every 6 months and wipe the surface with a
damp cloth.
8. TROUBLE SHOOTING
Problems are indicated in several ways
1. The smoke detector emits an acoustic signal twice every minute indicating
a malfunction.
2. The smoke detector emits an acoustic signal once every minute indicating a
low battery. Replace the battery as above.
3. The smoke detector emits an acoustic signal once every 11 seconds indi-
cating the test button is jammed on. Press the test button to reset.
4. The full alarm sounds for no reason. (A repeating series of three beeps with
flashing light). Clean the alarm as above.
5. The alarm does not sound when pressing the test button.
6. The red LED remains steadily on or off. (i.e. does not flash approximately
once every minute, when the unit is not in alarm).
7. The green LED is off.
