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.
