Why does my ADEMCO LYNX Security System keypad beep periodically?
K
Kevin ReyesAug 18, 2025
Your ADEMCO Security System keypad may beep periodically because the system is in Test mode, a transmitter low battery has occurred, or a supervision fault has occurred. To exit Test mode, enter your code and then press OFF. If it is a low battery, replace the battery after entering your code and pressing OFF. For a supervision fault, check the indicated transmitter and restore communication to the receiver.

If your ADEMCO Security System keypad displays a low battery message, it could be due to a low or missing system battery, a low battery in the remote RF keypad, or a low battery in a specific transmitter. Replace the system battery, the battery in the RF keypad, or the battery in the displayed transmitter, as appropriate.

Intrusion alarms for no apparent reason in your ADEMCO Security System can occur if a protected door or window was opened while the system was armed, there's improper user operation of exit/entry delays, or magnets are located too far from switches. Check with all occupants, verify entry and exit delay settings, and check all openings for proper switch and magnet orientation.

Donald AndersonSep 6, 2025
If your ADEMCO Security System is not responding to keystrokes on the keypad, it could be communicating with a downloader at the central station or undergoing its one-minute initialization process after being powered on. Wait until the download session is finished or allow the initialization to complete, or bypass the initialization by pressing '#' + '0.'

How to resolve ADEMCO Security System transmitter zone number that appears during Transmitter Sniffer mode, but does not clear?
A
Amy BrownSep 8, 2025
If the transmitter zone number appears during Transmitter Sniffer mode, but does not clear on your ADEMCO Security System, ensure that the transmitter zone type (ZT) is set to a valid active zone type in field *56. Also, verify that the transmitter battery is installed and that the 5800 System transmitter is 'entered' in the system via field *56 or *83.
