A range of indicator units with either red or yellow indicators to provide an audible and visual status of alarms, isolation’s or other functions.

These units are available with a keyswitch to silence the internal buzzer or a keyswitch to illuminate the indicator and buzzer. A volt-free contact is provided when the keyswitch is operated for ancillary control functions.
