This sounder has been fully approved to EN 54-Part 3 by the LPCB and VdS on tones 1, 8, 11, 25 and 27.

All the standard features are retained including the facility to select from three volume settings via the DIL switch. This allows individual sounders to be retro-converted to high output devices where additional sound output is required.

Tones are selected via the DIL switch on the PCB. By using 3-wires, a second stage alarm may be switched so that the second tone will over-ride the selected tone.

Standard with all VTG products is a universal locking system. Utilising an industry standard grub screw, each VTG product may be locked in place, making VTG fully compliant with the latest requirements of British and European standards.

Quick fit mounting is achieved by the bayonet fixing arrangement on each base and is standard on both base variants. The deep mounting base features a throw-away cover plate for surface mount wiring. This is kept in place when wiring directly through into the rear of the product.

The VTG sounder contains an array of features and benefits that installers are rapidly becoming familiar with. With its quick fit shallow base or its IP65 multi-purpose deep base, VTG gives a high output 105 dBa as standard. The volume setting (low, medium or high) is selected via the DIL switch with the required tone.

VTG has 32 standard tones for the UK market, with alternatives for other countries. VTG sounders are delivered with the volume set to a nominal 101dBa output, and the tone set to sweep. Two-stage alarm is available by using 3 wires.

With an operating frequency of 800 to 1000Hz, each sounder provides sound within the frequency range specified by BS5839 and has a wide operating voltage of 12-35Vdc.
