The groundbreaking Thermoptekô technology in the ST-620 provides responsiveness to all fire types in one alarm and removes the need for ionisation alarms - putting the environment first.
Thermoptekô 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
We recognise that not all batteries are made the same Ė the ST-620 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 alarmThe ST-620 is the first of FireAngelís Green Product Initiative.
Every scrap of excess has been removed, from plastic in the alarm casing, a single sealed battery to last the life of the alarm (as opposed to 10 replacement batteries) and environmental packaging.
The planet has been considered at every juncture of the alarms development.
