CHOICE AND LOCATION OF ALARMS
Heat Alarms are most suitable for kitchens, boiler rooms, workshops and
garages where dust, dirt and moisture contribute to nuisance alarms in smoke
alarms.
NOTE: Heat alarms should NOT be used on walls and in escape routes and
should always be interlinked to smoke alarms.
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 and heat alarms in:
SINGLE STOREY HOME WITH ONE SLEEPING AREA.
SINGLE STOREY HOME WITH TWO SLEEPING AREAS
MULTIPLE STOREY HOME WITH MULTIPLE SLEEPING AREAS
SMOKE ALARMS FOR MINIMUM PROTECTION
SMOKE ALARMS FOR INCREASED PROTECTION

AVOID THE FOLLOWING LOCATIONS
The life of this alarm can be significantly reduced by adverse environments, incorrect location, and a failure to regularly clean and maintain it in accordance with the instructions below. Incorrect location and a lack of reasonable care may also cause it to malfunction and will invalidate the warranty.
-
Do not locate near fans or extractors. These can pull smoke and heat away from the alarms.
-
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.
-
Do not install less than 300mm from walls and light fittings when mounted on the ceiling where heat and dead air may prevent smoke and heat reaching the alarm.
-
Do not install smoke or heat alarms on poorly insulated walls and ceilings where cold air boundary layers could delay smoke and heat reaching the
alarm. -
Do not install near objects that could prevent smoke and heat reaching the alarm.
-
Do not install close to fluorescent light fittings that could trigger nuisance alarms.
-
Do not install in escape routes from the building.
-
Do not paint the alarm.
The location of the alarms must be in accordance with applicable building regulations, in particular Part B. Further help and guidance can also be found in BS5839 part 6.
FURTHER DETAIL ON ALARM LOCATION
IMPORTANT NOTE: To give the earliest warning of a developing fire, smoke alarms should be installed in escape routes and all the rooms of your home and interlinked. (other than those in section 3, AVOID THE FOLLOWING LOCATIONS).
-
Heat alarms should be at least 300mm from any wall or light fitting.
-
They are not to be mounted close to or above heaters or air-conditioning vents.
-
Do not install heat alarms in escape routes from the building. Where used in other areas, heat alarms should be no more than 5.3 metres from other heat or smoke alarms.
-
Do not install heat alarms in sleeping areas; for example, bedrooms, nurseries, playrooms or areas where the elderly and disabled may spend
long periods of time. -
Do not install heat alarms on walls.

INSTALLATION PROCEDURE
Important Note: Mains powered smoke and heat alarms should be installed by a
qualified electrician and in accordance with Part P of the Building
Regulations, BS7671 and BS5839 pt 6: 2004 section 15.5, Grade D systems.
WARNING: To prevent Injury, this apparatus must be securely attached to
the ceiling in accordance with the installation instructions. Batteries shall
not be exposed to excessive heat such as sunshine, fire or the like. Storing
or installing alarms in temperatures below 5°C and above 30°C, and in low
humidity may cause beeping and nuisance alarms when first installed. These
will clear after a short time when the alarm 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-namers 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 1mm 2 “3 core and earth” cable (6243Y); with the
Brown to Live (L), Grey to neutral (N) and the Black to Interlink (I). All
alarm circuits should be protected by a 6amp over-current device. The maximum
total length of wiring should not exceed 250m. Mini-trunking systems can be
used via the removable cover shown in Fig.4 below
Installation:
WARNING: Ensure the power supplies are turned off before installing smoke and heat alarms.
-
Using the fixings supplied attach the base plate of the alarm to the desired position.
-
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.
