Addressable sounders

Base sounder

The CAS380 is a loop-powered integrated sounder and sensor mounting base. It can be used with any analogue sensor or as a standalone sounder with the optional CASC cover plate.

Wall sounder

The CAS381 range of loop-powered addressable wall sounders offers a highly efficient, low current sounder option. Sounder volume and tone are set at the analogue panel avoiding the need to access each sounder individually to alter settings.
