Where should Heat Detectors be fitted?
Heat detectors are best suited to areas where dust, fumes and moisture can cause nuisance alarms in alarms such as; kitchens,
laundry rooms, lofts and garages.
Heat detectors must be ceiling mounted in the centre of the room. They should be at a distance no greater than 5.3m from the
farthest wall, no greater than 5.3m from a door to any room in which a fire might start and no greater than 5.3m from the next
heat detector. Heat detectors should not be wall mounted.
Thermistek technology activates the alarm sooner if it predicts a significant rate of rise of temperature.
Refer to the Manufacturer’s instruction booklet for more information on positioning.
Typical Tools Required
Be careful when using step ladders – always face the direction you are working.
Always make sure the correct drill bits and screwdrivers are used.
A drill and screwdriver are not required if the self adhesive pads are used.
How to install a Heat Detector
Make sure you have read and understood the instructions on positioning the detector before starting.
The base plate must be securely fixed to the ceiling or wall.
Use the fixing slots on the base plate as a guide when marking the position of the drill holes.
Fix with the screws and plugs provided.
Alternatively, the base plate can be fixed with the self-adhesive pads provided.
Ensure the surface is smooth, clean and dry.
Press hard to make sure the self-adhesive pads are properly adhered.
Position the detector on the base plate then twist it clockwise until the detector is
fully locked in position.
The battery power will now be switched on and the red light will flash once
every 45 seconds to show that it is active.
IMPORTANT: when the heat detector is fitted to the base plate it enters a power-up initialization period.
It is possible the first Test/ button press will be missed during this period. All subsequent Test/ button presses will function
correctly. Heat will always be detected during the initialization period.
WARNING: Removing the heat detector from its base plate will de-activate the unit and prevent it from detecting fire.
How to test the Heat Detector
Press the Test/ button in the centre and release.
The red light on the detector will flash rapidly during the audible signal.
The unit will sound an audible alarm consisting of 2 cycles of 3 loud beeps,
then stop automatically
The Test/ button is used during installation to register the heat
detector onto the warden call system, at-home alarm or Nursecall system.
See the following pages for how to put each of these products into registration mode.
The range of all radio devices can be affected by the working environment.
Always take care during installation and perform several test calls.
