The controller status LED is the primary rear panel indicator of alarms. An alarm is

generated when a specific condition is identified and is cleared when the specified

condition is no longer detected. When an alarm is posted,

1. The controller status LED turns orange for 5 seconds

2. The controller status LED turns off for 5 seconds

3. The controller status LED flashes orange the number of times specified by the first

digit of the alarm code

4. The controller status LED turns off for 3 seconds

5. The controller status LED flashes orange the number of times specified by the

second digit of the alarm code

Steps 2-5 are repeated for each alarm posted. The entire process is repeated as long as

the alarms are still posted.
