ACM 150
Troubleshooting
Identifying problems
Utilizing relay outputs
The ACM 150 monitor computer constantly monitors the operating status of the
system. If any problem develops that requires the user's attention, it generates a
message identifying the problem. The sooner you are aware of a problem, the sooner
you can take actions to resolve it and minimize (or even avoid) downtime. Therefore,
it is critical that you utilize the relay outputs that activate under these conditions:
•
81 Power fail
•
82 Watchdog timer (computer problem)
•
83 Manual mode
•
84 General malfunction
•
85 General Alarm 1
•
86 General Alarm 2
NOTE
These relays should be wired to a central control system or alarm panel that
is monitored by personnel so that conditions requiring service attention are
known as soon as possible.
Utilizing daily inspections
As a backup to monitoring the output relays, a quick daily inspection of the ACM 150
monitor is recommended. It will help you identify problems, and it provides you with
an inspection record.
If you are unable to go to the system, you can check the display from a remote
location, looking at the Status Bar and Recent Scan mode, and check off the upper
part of the form.
