Audible signalling product range
Bells are a cost-effective, traditional signalling device with a wide range of signalling applications. They offer medium dB output with a unique sound. Moflash offers two types: solenoid driven for industrial applications, where they are under constant daily use, and a motor driven type more suitable for fire alarm applications.
Either electro mechanical type where the diaphragm is deflected by a moving magnet, which is triggered by a make and break contact, or the Piezo type where the diaphragm is controlled by an electronic circuit. The mechanical versions offer medium/high dB output with low frequency sound and are of robust construction.
Electronic sounders/sounder beacons
Electronic sounders are now the most versatile audible warning devices on the market today. With multiple tone and decibel selections, this type of products will satisfy most applications, with the added benefit of remote tone selection and voice activation.
Sirens are powerful motor driven signals driving an internal impeller through a slotted cover, creating a unique penetrating sound, traditionally recognisable for creating the ‘air raid’ warning signal. Piezo versions are relatively low dB and high frequency and are only suitable for local signalling applications.
