HEAT ALARM SENSOR TECHNOLOGY
Thermistek technology incorporates a unique radiant heat dish (patent pending) to heighten performance
when exposed to a radiant heat source in real fire situations. Constantly monitoring for temperature
change, if an increase in temperature is detected, the rate of rise is measured and if predicted to exceed a
pre-determined threshold will sound the alarm. This predictive quality provides a quicker response time in
rapidly increasing temperatures.
Heat alarms are designed for areas where dust and fumes may trigger frequent nuisance alarms in
conventional smoke alarms - ideal for attics, garages and kitchens. The HM-F-NEU / WHM-F-NEU are
fixed point heat alarms using Thermistek sensing technology. All alarms are approved to class A1 and will
activate when the temperature reaches a preset range of 54 °C to 65 °C.
LITHIUM BATTERY TECHNOLOGY
All FireAngel mains powered smoke and heat alarms have a built in, sealed for life lithium battery (back-up);
designed to power the alarm in the event of a mains failure.
POSITIONING
Locations of alarms must be compliant with either BS 5839: Part 6 or relevant Building Regulations if in any
doubt. This alarm is not intended for any non-residential, commercial or industrial application, nor for any
other purpose other than described in the above. For the best protection, heat alarms should always be
installed as part of a complete fire protection system that includes smoke alarms.
IMPORTANT:
Check with local building and fire regulations for your property, to ensure compliance.

This user guide covers a number of different models. Some of the illustrations may look different to your
particular model.

SMOKE ALARM SENSOR TECHNOLOGY
Thermoptek technology provides a fast reaction to both slow smouldering & fast flaming fires in a single
alarm. Constantly monitoring temperature changes, if a rate of temperature rise is detected the sensitivity of
the alarm is increased.
DO:
• Leave this guide with the end user.
• Connect the alarm as late as possible in an installation, particularly in new builds,
to avoid contamination.
• Remove the dust cover before applying power.
• Ensure that after any building work or after repositioning large items of furniture (beds, sofas,
shelving units etc.), you carry out an alarm test on all alarms to ensure they are still working.
• Test your alarm weekly as well as testing any other interconnected alarms.
• Make sure your alarm is situated in one of the recommended locations only.
DO NOT:
• Expose this alarm to moisture, dripping, splashing, steam or condensation.
• Paint the alarm.
• Install heat alarms in escape routes instead of smoke alarms.
• Test your alarm with a naked flame. The test button tests the alarm’s full functionality.
• Ignore any alarm in the network if it is sounding, it is warning you of a potentially hazardous situation.
