Product details
The VSO base sounder is for use with conventional fire alarm systems, including two-wire (SAV-WIRE®), and is designed to accept most leading detector bases, offering a cost-effective solution for sounder installation. The low-profile sounder is supplied with 32 tones, along with a two-stage alarm override 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 worldwide. All tone options are fully synchronised. This sounder is 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 the unit can be used as a standalone sounder.
