The annunciators are designed to provide the possibility of supplying light and sound alarms in fire alarm and fire extinguishing systems when working together with receiving and control devices. The siren can be used in hazardous areas and rooms of classes 1 and 2.

When the supply voltage is switched on, the siren sends light, sound or simultaneously light and sound warning signals. Two microswitches allow you to select the operating modes of light and sound alerts: intermittent or continuous glow; " Siren" or " horn" .
