Sounder with LED beacon A9091T

self-extinguishingIP21wall-mounted

Product Overview
The A9091T addressable sounder beacon provides combined audible and visual alarm signaling when connected to a DC24V loop-powered bus. Compatible with bus-type fire alarm control panels, it activates on receipt of an alarm command to warn occupants and support evacuation with a synchronized white LED flash and selectable alarm tones.

Applications
Intended for use in commercial and residential buildings: high-rise residential, public venues, hotels, entertainment facilities, factories, shopping centres, hospitals, schools, offices and trading floors. Particularly suitable for environments with low visibility or where smoke may form.
