The VPR Spatial sounder is designed for applications where a non standard tone may be required. It includes the majority of sound patterns and frequencies used throughout the world, and is also fully synchronised.

With an operating frequency of 440 to 2850Hz, each sounder provides an audio able alert within the frequency range specified by BS5839.

This sounder is primarily for use in fire alarm systems but can be used in most applications requiring a high sound output and economic current supply. A choice of 16 or 32 fully synchronised primary sounds can be selected via a 5 way (4 way for 16 tones) dil switch each with an alternative continuous tone for selection on the PCB terminals or by third wire remote control.

The product’s case material is constructed from fire retardant ABS. Each sounder is supplied with its own mounting base which comes complete with marker points for two M20 gland entries. The installation of the VPR-MT sounder is not recommended in chilled areas.
