outputs will be operated and the internal buzzer will be silent.
The wiring to the detection circuit and the
FirePro
Condensed Aerosol Generators is
supervised and disconnection of any of this wiring will be shown by illumination of the
yellow Fault indicator on the front panel and operation of the internal buzzer.
The internal fault volt free contact will operate and signal any external equipment that is
connected to the controller. Internal indicators are provided to show whether it is the
detection circuit wiring or the wiring to the Condensed Aerosol Generators that has a
fault.
The buzzer may be silenced by pressing the Buzzer Silence button.
Upon activation of a linear heat detection cable or smoke detector the red Fire indicator
