The EVSO base sounder is for use with conventional fire alarm systems, including two wire (SAV-WIRE®) and is designed to accept most leading detector bases and offers a cost-effective solution to sounder installation. The low profile sounder is supplied with 32 tones, along with a two stage alarm override which is activated by a third negative wire from the fire panel.
All tones have been selected to comply with the latest sound patterns and frequencies used throughout the world. All tone options are fully synchronised. This sounder has been fully approved to EN54-3 by the LPCB and VdS on tones 1, 3, 11, 25 and 27.
When a detector is not fitted to the sounder, a blank cover plate is available so that the unit can be used as a standalone sounder.
The Intelligent Twin Switch Monitor provides the function of two Switch Monitor units within one enclosure. The two units are electrically independent of each other.
