Description

FireAngel ST-750T Thermoptek Smoke Alarm The Fireangel ST-750T is a 10 years sealed battery powered alarm equipped with the thermoptek muliti-sensor. The alarm responds twice as fast as a normal optical smoke alarm. The alarm's thermoptek sensor combines the optical sensing technology with a thermal enhancement to detect both fast flaming and slow smouldering fires. It constantly monitors for temperature change and if a sudden rise in temperature is detected the alarm sensitivity is increased. This smoke sensor makes it the technology of choice for the UK's fire and rescue service. FireAngel Heat Alarm with 10 Year Sealed For Life Battery, FA6720-R (HT-630 replacement, new gen), White FireAngel design their heat detectors in-house and rigorously test them to ensure the highest standard of protection for your family and home. Install in your kitchen, loft / attic and garage for a fast alert to fire without the false alarms due to dust and humidity. For complete protection install alongside smoke alarms in your hallway, landing, living room and bedrooms and carbon monoxide detectors in any room with a fuel burning appliance, as well as living room and bedrooms. Suitable for homes in England, Wales and NI. Not suitable for homes in Scotland.
