5.5 Power Failure
In the event of an electrical failure, the system
will recover automatically and should require
no additional programming if the electrical
power is restored within 3 days.
When electrical power is restored after a
power failure, verify the status of the LED D41
on the controller board (B). Refer to Annex A,
Table 3 for Status LED definitions. If the LED is
OFF use an initialization card with the reader
and perform a time reset on the RAC 4 as per
the FDU or ATLAS manuals.
NOTE:
When the power to the RAC 4 is lost,
the controller PCB stops functioning
and the on-board relay will return
to its normal state. Any peripheral
connected to the relay will then be
either in a normally open (NO) or
normally closed (NC) state, dependent
on the wiring.
5.6 Loading Recommendations
CAUTION:
Do not exceed the load limitations of the
control panel.
The maximum recommended load for the
output relay in the RAC 4 system is 1 Amp at
30 VDC.
The current supplied by the controller PCB is
for the locking device used is 0.75 Amps from
connector J18, pin 1. Refer to Annex A, Table
3.
5.7 System Deactivation
In order to deactivate the card reader control
panel, disconnect the AC power either by
removing the power adaptor from the wall
outlet, or by shutting off the main breaker
switch for the AC line to the wall outlet the
control panel is connected to.
