The Zeta addressable sounder circuit controllers (ZSCC) module is used to connect conventional fire alarm devices (Bells, Flashers or Sounders) to an addressable Zeta system.
Require external power to be supplied from a suitable 24v power supply and include a built in loop short circuit isolator to help keep the unit operational in the event of a problem on the loop wiring.
As with all Addressable interfaces, the outputs are controlled by the panel to which they are connected. Consequently the interfaces will behave differently on different panels, i.e. some may allow the outputs to be programmed, others will have a default “pre-programmed” operation.

It has 3 LEDs on the front of the unit, one for alarm, one for local fault and one for addressable loop fault (isolator active).
