The Viper spatial sounder is available in two popular formats.
The VPR-SA2 sounder is designed for applications where low current consumption relative to sound output is required, with a 103 dBA output requiring only 11mA at 24Vdc.
The Viper SA4 sounder is designed for applications requiring maximum sound output, and probably offers the best sound output to cost ratio of any sounder currently on the market.
With an operating frequency of 800 to 1000Hz, each sounder provides sound within the frequency range specified by BS5839. Each sounder also has a wide operating voltage of 8-35Vdc.
Tones are available by selecting either warble, sweep or pips via the jumper 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.
Each sounder is supplied complete with its own mounting base which comes with marker points for drilling M20 gland entries. Colour, finish and tones match those of the Vantage, Vara and Vector sounders.
