The Apollo Series 65 Heat A1R Detector has two thermistors. With one exposed and the other insulated, they monitor temperatures. Should this increase rapidly, the alarms will then get triggered.

The rate-of-rise heat detector can go where your smoke detector can’t. These include areas which are dusty or smoky.

Using this detector with a variety of different sensor types gives you a solid fire alarm system. It shares a similar look to other Apollo detectors, meaning you’re not sacrificing appearance for safety.

Please note that bases are not supplied, and sold separately.
