Unite 7885653303 User manual

1. DESCRIPTION
All Unite smoke detectors are approved to the most recent and rigorous stand-
ards. The photoelectric smoke detectors with their unique X-Profile sensing
chamber are approved to EN14604: 2005 and are particularly sensitive to
slow smouldering fires typically originating in living rooms, bedrooms and
hallways whilst being highly resistant to nuisance alarms.
The alarms are guaranteed for 6 years. However, their lives can be significant-
ly reduced by adverse environments, incorrect location and a failure to regu-
larly clean and maintain them according to the following instructions. Incorrect
location and a lack of reasonable care may also cause them to malfunction
and will invalidate the warranty.
Product Features
• All models are supplied with a back-up power source. The 7885653316
has a longlife lithium battery and the 7885653303 has 3 x AAA replace-
able alkaline batteries.
• Alarm Silence – Silence your smoke alarm by momentarily pressing the
test button. Ideal in non-emergency situations when nuisance alarms may
have been created, for example, by steam. The red light flashes every 8
seconds to remind you that the smoke alarm has been silenced and will
automatically reset to quiescent mode in 10 minutes.
• Bespoke software maximizes detection ability and false alarm rejection.
• Power automatically switched on as detector is installed onto its mounting
plate and automatically switched off when detector is removed.
• A permanent green LED indicates mains power is connected and switched
on.
• Red LED flashes approximately every minute confirming unit is receiving
power and ready to detect fire conditions. (Quiescent Mode)
• Low Battery Warning alarm gives one acoustic alarm every minute.
• Low Battery Warning Silence – Low battery warnings often start at night.
Silence the audible warning for ten hours by pressing the test button, thus
avoiding removing the alarm from its mounting plate and turning it off. The
batteries on non-rechargeable battery alarms can then be replaced when
convenient the following day.
• Extra Large Test Button for ease of use, tests sensitivity, circuitry, power
supply and alarm sounder.
• Loud 85 Decibel Piezo Electric alarm automatically resets when hazardous
condition has passed and chamber is clear.
• Easy Installation – fixing screws and plugs supplied.
• The built in interconnect facility allows the connection of a combination
of up to 15 smoke detectors together so that when one alarm sounds all
connected alarms will sound.
2. CHOICE AND LOCATION
Optical Smoke detectors are best at detecting smouldering fires such as those
started in electrical equipment, clothing and soft furnishings such as seating,
bedding, curtains and carpets. They are, therefore, ideally suited for living
rooms, bedrooms and escape routes in domestic accommodation.
For minimum protection, install at least one smoke alarm on each level of your
home. They should be installed in hallways, corridors and all escape routes
from the building and within 3 meters of all bedroom doors. All alarms should
be interconnected.
Recommended siting of smoke detectors in:
Single storey

3. AVOID THE FOLLOWING LOCATIONS
The life of this smoke detector can be significantly reduced by adverse envi-
ronments, incorrect location and a failure to regularly clean and maintain it in
accordance with the instructions below. Incorrect location and a lack of rea-
sonable care may also cause it to malfunction and will invalidate the warranty.
1. Do not locate near fans or extractors. These can pull smoke and heat away
from the smoke detectors.
2. Do not install smoke detectors in or near high humidity areas such as
showers, bathrooms or kitchens where humidity levels exceed 85% or the
room temperature exceeds 40°C or falls below 0°C. These conditions may
cause nuisance alarms and damage.
3. Do not install in the peak of an “A” frame or sloping ceiling. This may delay
smoke and heat reaching them due to the presence of dead air.
4. Do not install less than 300mm from walls and light fittings when mounted
on the ceiling where heat and dead air may prevent smoke reaching the
alarm.
5. Do not install smoke detectors in insect infested areas.
6. Do not install smoke detectors in areas subjected to heavy concentra-
tions of cigarette smoke that will cause nuisance alarms and the smoke
detector to become contaminated.
7. Do not install smoke detectors in boiler rooms and garages where fumes
and dust may cause nuisance alarms.
8. Do not install near objects that could prevent smoke and heat reaching
the alarm.
9. Do not install close to fluorescent light fittings that could trigger nuisance
alarms.
10.Do not paint the alarm.
The location of the alarms must be in accordance with applicable building
regulations.
4. FURTHER DETAIL ON SMOKE DETECTOR
1. At least one smoke detector should be installed in the escape route from
all floors of the building.
2. The detection element of smoke detectors should be between 25mm and
600mm below the ceiling, or in the case of heat alarms between 25mm
and 150mm
3. Smoke and heat alarms should be at least 300mm from any wall or light
fitting.
4. If ceiling mounting is impractical smoke detectors may be installed on
walls provided that the area is no longer or wider than 10 meters and
the total area does not exceed 50 square meters and that: -
a. The smoke detector is between 150mm and 300mm below the
ceiling.
b. The bottom of the smoke detector is above openings such as vents,
doors and opening windows
c. They are not mounted close to or above heaters or air-conditioning
vents.
5. Where smoke detectors are located in a hallway, corridor or landing,
the smoke detectors should be no further than three meters from any
bedroom door to assist audibility behind closed doors.
6. For maximum protection no point should be further than 7.5 meters from
any smoke detector
7. To give the earliest warning of a developing fire, smoke detectors should
be installed in all the rooms of your home and interlinked. (other than
those in section 3, AVOID THE FOLLOWING LOCATIONS).
5. INSTALLATION PROCEDURE
IMPORTANT NOTE:Mains powered smoke detectors should be installed
by a qualified electrician and in accordance of the Building Regulations.
WARNING: Storing or installing smoke detectors in temperatures below
5°C and above 30°C, and in low humidity may cause acustic signals and
nuisance alarms when first installed. These will clear after a short time when
the smoke detector has become acclimatised. Extended periods under these
conditions will reduce the life of the alarms and invalidate the warranty.
Do not expose to dripping or splashing. Disconnect the alarm before
dismantling. Interconnect terminals and circuits are not to be accessible and
must only ever run to other Interconnect terminals. Do not interconnect to
alarms with other brand-names or made by other manufacturers.
The power supply should be from one of two sources:
a. An independent circuit at the dwellings main distribution board with no
other electrical equipment connected (other than a dedicated supply
failure monitoring device) or:
b. A separately electrically protected and regularly used local lighting
circuit. Only suitably approved cabling should be used. The alarms
should be wired using a minimum of 1,5mm2 “3 core and earth” cable;
with the Brown to Live (L), Grey to neutral (N) and the Black to Interlink
(I). All alarm circuits should be protected by an over-current device. The
maximum total length of wiring should not exceed 250m.

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.
What to do if the acoustic alarms sound
Alarms sounds are as follows:
Full alarm indicating
smoke and fire
Repeating series of 3 beeps every
4 seconds with flashing light ··· ··· ··· ···
Low Battery Single beep every minute · · · ·
Test button jammed One beep every 11 seconds · · · ·
Other fault Double beep every minute ·· ·· ·· ··
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)
