VIPER Spatial Sounder

The Viper spatial 32-Tone 110-230v ac sounder is designed to give a high output for applications requiring a mains operated sounder and where a non standard tone may be required. It includes a wide range of sound patterns and frequencies compatible with International requirements.

Each device is synchronised via its high frequency oscillator circuit, and gives sound outputs with frequencies of between 440 to 2850Hz. (dependent upon tone selected).

Tones are selected via the DIL switch fitted to the PCB. By using three wires, a second stage alarm may be switched so that the continuous tone will override the tone selected.

The sounder case material is ABS and is supplied as standard in red. A white version is also available.Each sounder is supplied complete with its own mounting base, which contains marker points for drilling two M20 gland entries.

The installation of the VPR-MT32-230 sounder is not recommended in chilled areas

These units do not require an earth connection as each device has its own transformer and de-coupling between mains frequencies.
