Troubleshoot Using the Transmitter Survey LED
If a transmitter is unable to reliably communicate a message to the receiver, or is reported as missing, the Survey
LED can be used to help diagnose the issue. If the missing transmitter cannot be explained by obvious reasons such
as a damaged transmitter, failed battery, or changes in building construction; then the Survey LED should be used.
To use the Survey LED operation to help diagnose a field issue, complete the following steps on an 1100 Series
transmitter. Repeat the following sequence 5 times and write down the LED operation for each tamper switch
action.
• Press and hold the tamper switch
• Observe the LED until it turns off for at least 5 seconds
• Release the tamper switch
• Observe the LED until it turns off for at least 5 seconds
You now have observed the LED 10 times. Based on the results you have recorded use the list below to assist in
troubleshooting.

LED turns on for more than 1 second 3 to 9 times.
• The transmitter or receiver needs to be relocated
LED turns on for more than 1 second all 10 times.
• The receiver is not turned on, or is not operating
• The transmitter is not programmed into the receiver
• The transmitter or receiver needs to be relocated
LED flashes multiple times with a single tamper press or release 3 to 10 times.

• The tamper switch is being pressed or released too quickly
• The tamper switch or other part of the transmitter is broken
LED stays on constantly and is dim.
• The transmitter battery is almost dead
• The transmitter is broken
General Wireless Troubleshooting
If ALL wireless devices do not operate, refer to the following checklist:
• Verify equipment model numbers.
• Verify the House Code (1-50) is programmed in System Options.
• Verify the 4-wire connector from the receiver PANEL header is connected to the panel terminals 7, 8, 9, and
10.
• Verify what zone numbers are assigned as wireless zones and check the address settings of other device(s)
connected to the keypad bus to ensure no duplicate addresses have been used.
• Verify the LEDs are operating as listed in LED Operation on the previous page.
• Verify transmitters have batteries correctly inserted.
