Product Features
What this model is for, what it does well, and what to confirm before it goes on a project.
Perimeter and open-area fire detection where a linear beam path of 5 m to 100 m must be monitored within an addressable fire alarm system.
Covers beam paths from 5 m to 100 m, letting one detector watch long corridors or open spaces instead of many point detectors.
A blue standby flash and steady red alarm light make it easy to confirm detector state during routine checks.
Rated for -35°C to +65°C operation, so it suits demanding indoor and sheltered environments.
