5 Status Indicators
Status indicators appear on the front of the ACTpro-120.
The meaning of each indicator is described below.
(A) Power / System Running
This indicates that the ACTpro-120 has power.
(B) Communications
Constant illumination indicates that the door station is online.
(C) Fault
Illuminates to indicate a fault on the system.
Possible causes are:
l Tamper open: Door station housing is not closed.
l Break Glass: The fault LED will illuminate if the emergency break glass switch is activated.
l Comms Offline: Door station is offline.
l AC Fault: ACTpro-100 door station will accept an AC present signal from a PSU (pre-wired on ACTpro-
120). This is wired into AC PRESENT input on the PCB. When the PSU has no AC supply the fault is
active.
l Low Supply Voltage: When voltage to the +12V terminal is less than +9V.
l Fuse Blown: The +12V output on the READER terminals is current limited to provide short circuit
protection. The Fault LED will illuminate if too much current is drawn from this connection.
