C series piston striker operated electromagnetic audible alarms with piston clapper emit characteristic sounds that can be immediately heard and recognised. The low frequency sounds emitted carry a long way and are ideal for communicating alarms. There are two versions of alarms supplied for AC or DC power supply and these units are ideal for continuous operation.

The alarms are made with three different bell sizes:

  • C165… alarm with 165 mm diameter bell
  • C215… alarm with 215mm diameter bell
  • C265… alarm with 265mm diameter bell
