The ASC2366 is a RED bodied, shallow base addressable ceiling mount room sounder/VAD for fire alarm systems running 2000 series fire protocol. Multiple tone selection and full CPR approval ensure conformance to local regulations. The beacon has a RED lens and a flash frequency of either 0.5 or 1 Hz (selectable on installation). The 2000 series sounder/VADs operate over a 2-wire 2000 series loop and are loop powered i.e. no external power supply is required. The ASC2366 is compatible with automatic phased-start synchronisation controlled from the fire panel.
