When you open the front door and observe the ECU, you will see the d02 code displayed. This also indicates that there is a wiring
issue with the intrusion switch somewhere.
If you momentarily depress the Audible Alarm Cutoff / Maintenance / Reset pushbutton located on the ECU, the ECU displays “UP”
and the audible alarm ceases, but there is still a problem and the alarm will activate again in 30 minutes.
Check for a broken door intrusion switch or an open in the wiring.
Recommended Practice to be Performed after a Door is Open
To check for a broken door intrusion switch or an open in the wiring, perform the following procedure whenever a door has been
opened.
1.
As a final check, before leaving the site, ensure all panels are properly closed.
2.
With the front door open, d01 or d02 should be displayed on the ECU.
3.
Pull the front door intrusion switch out. This places this switch in the disabled position.
4.
Observe that “UP” is displayed on the ECU. This confirms that the door intrusion wiring has no open conditions.
5.
Close the front door.
