Troubleshooting Door Alarms
The following steps can be used for troubleshooting door alarms.
Remember to keep a good set of notes as you troubleshoot.
These notes can help for comparison to find problems, prevent
confusion, and help speed things up if site service by a technician
or telephone technical support are required.
1 Determine if the problem with a single door (or alarm input),
or with a bank of doors.
2 Check the doors in question. Are they loose, possibly moving
due to wind or vibration from traffic?
3 Check the wireless multiplexer. The circuit boards, cases, and
wiring should be checked for obvious damage (i.e., vandalism,
burn marks from power surge/lightning, corrosion on the
circuit board, water marks, insects, construction debris, etc.).
Problems within unused channels:
1 Connect a length of 24 AWG wire from
pin #5
of the power
and data terminal block to one of the four screws that mount
the circuit board to the metal case.
The metal case of the multiplexer must also be mounted
directly to a grounded metal building or tied to a ground rod
or grounded metal structural element of the building such as a
metal water pipe or ground rod in accordance with local code
