How to troubleshoot ADEMCO LYNX Security System no response to a transmitter in normal operation?
- MMadeline SaundersSep 12, 2025
If there is no response to a transmitter in normal operation with your ADEMCO 5800 System, but the zone number clears during Transmitter Sniffer mode, it could be due to the wrong input being 'entered' during programming or the physical transmitter not being entered by the system. Delete the input's serial number and enter the proper input in field *56, or reprogram the necessary transmitter for the zone.
