Requiring no special wiring, can be retrofitted to existing installations. They are fully synchronised and have an exceptionally low current consumption. Use as a replacement for electronic sounders or bells to broadcast a clear message for any situation – evacuation, chemical spills, lockdown alert, security or general information. Where pre-alarm, test and other supplementary messages are required, up to seven different messages can be programmed into the sounders from a library of hundreds – with foreign language and bespoke messages also available. Using our Voice Controller each message can then be triggered using a variety of inputs.
