Fire Angel ST-622T Smoke Alarm Thermoptek Lithium Battery
The ground-breaking Thermoptek technology in the ST-622 provides responsiveness to all fire types in one alarm and removes the need for ionisation alarms – putting the environment first. This is the smoke alarm of choice for the UK’s Fire & Rescue Services.
Thermoptek technology combines the very latest in optical sensing with thermal enhancement, providing fast reaction to both slow smouldering and fast flaming fires in a single alarm.
includes 10-year laser-welded lithium power pack which prevents moisture ingress to ensure the alarm will remain powered for life.
An all new and improved universal backing plate guarantees quick and easy fitting. A larger, concave central button has been designed for easier silencing and weekly testing of the alarm.
Sleep-easy function allows the warning chirp to be temporarily silenced for 8 hours when the alarm starts to reach its end of life, by simply pressing the test button. Ideal for periods when it is inconvenient to change the alarm e.g. at night but when smoke detection is still required. Sleep-easy function can be activated 10 times, providing sufficient time to get the alarm replaced (recommended within 7 days).
