FireAngel FA6720-R Heat Alarm – 10 Year Sealed Battery
Protect kitchens, garages and utility rooms with the FireAngel FA6720-R Heat Alarm, designed to detect dangerous heat build-up without the nuisance alarms triggered by cooking fumes, steam or dust. Using advanced thermistor heat sensing technology, this alarm reacts rapidly to temperature rises — ideal for areas where traditional smoke alarms are prone to false activations.
The FA6720-R features a sealed, tamper-proof 10 year lithium battery, so there’s no battery replacement and no ongoing maintenance costs. A large central Test / Hush button makes routine testing simple and allows you to silence alerts when required. It’s also designed as an ideal replacement for FireAngel HT-630 heat alarms, with compatibility that can make upgrades quicker and neater.
A reliable, long-life solution that provides clear audible warning at 85dB and peace of mind for the rooms most at risk.
