Product description
Looking for a FireAngel ST‑622 smoke alarm replacement? Either FireAngel’s FA6620‑R or FA6615‑R smoke alarms can replace your end of life ST‑622 without requiring a new base plate or leaving unsightly holes in your ceiling.
Thermoptek technology combines the very latest in optical sensing with thermal enhancement and when compared to single sensor alarms react to fire in under half of the time ‑ meaning you and your family have vital extra time to react.
With power inputs to suit all installations, including sealed, tamper proof, batteries or mains powered options with back up batteries you can be confident your FireAngel device will protect you for years to come. The unit comes with a sealed, tamper proof battery that will last the lifetime of the alarm. The sensor within the unit will deteriorate after 10 years, so to ensure you’re protected we recommend you replace the unit after this time.
As well as allowing easy testing with a sweeping brush from the floor below, this large button also activates our Sleep Easy function which silences low battery chirps for 8 hours ‑ giving you a peaceful night’s sleep.
