## Description

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.

Review: Good value for a great product - Purchased recently to replace our detectors. A good buy with a 10 year guarantee so won’t have to change probably in our lifetime. In testing found detected smoke very quickly and siren necessarily easy to hear. They are really sturdy and very easy to install. Would buy again. Good value for money
Review: good product - well made, easy to install and does work well, as imoke from the hobt went off when pasta water boiled over and caused smoke from the hob. Hasn't gone off for no reason yet. Easy to test button, and red active light that blinks every 40 seconds to confirm it is working. So all good so far
