PALS Installation Manual
CRISIS CONTROLLER©™ HARDWARE (continued)
The Serial Watchdog includes an expansion unit that has a built in enunciator. It is set to ‘ON’ from the factory.
To deactivate it, remove the shunt marked ‘AUDIBLE’. If additional actions are required, should the watchdog
activate, a Form ‘C’ reed relay is available. This relay is only rated for 100m VDC, so if a higher rating is required,
an additional relay must be attached. Attach the expansion unit via the stereo jack to the Serial Watchdog. Attach
the female DB9 connector to the computer serial port. Attach the male DB9 connector to the Serial Receiver, if
present.
The DIP switches on the Serial Watchdog controller are factory set, they should not be
changed for any reason. If they are inadvertently modified, contact Actall® Technical
Support for assistance. There is no setup required for Serial Watchdog support in the
Crisis Controller©™ software.
Once installed, the Serial Watchdog is activated by entering the Alarm Monitoring mode on that machine (only the
machine with the watchdog is protected). It is sent commands using the same serial port as the Serial Receiver;
therefore a Serial Receiver must be assigned in the Crisis Controller©™ software, regardless of it actually being
attached. Should the Crisis Controller©™ fail to send the proper command every minute to the Serial Watchdog
while in Monitoring mode; the Serial Watchdog will reset that machine.
On reset, the Serial Watchdog generates a momentary on-board tone and the expansion unit enunciator (if set to
‘ON’) will sound for approximately 30 seconds, during this period the reed relay will also activate.
After reset, the machine has approximately 3.5 minutes to reload Windows®, run the Crisis Controller©™ software,
and return to Alarm Monitoring. If the system fails to re-establish monitoring, the Serial Watchdog will again reset
the machine.
Once the Serial Watchdog has been activated, it will remain activated until Alarm
Monitoring has been exited using the correct methodology.
