Description
Cranford Controls VPR-MT32-230-W White Sounder 110 / 230v 32 Tone
Each device is synchronised via its high frequency oscillator circuit and gives sound outputs with frequencies of between 440Hz – 2850Hz, (dependant on 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 industrial areas. These units do not require an earth connection as each device has its own transformer and de-coupling between mains frequencies.
