PJR2534 Posted May 16, 2019 Share Posted May 16, 2019 I have installed a Powermaster 33 along with a KP 250 Keypad. After months of no problems, the keypad display is now showing "No Communication" whenever any button is pressed. There is therefore no possibility of entering Installer Mode etc.. Is it likely that the communication failure is due to the keypad, the module inside the Powermaster control box or is it possible to reset the comms between the keypad and controller somehow? I would appreciate any help in resolving this matter. Thanks in advance. Quote Link to comment Share on other sites More sharing options...
Secware_Tech6 Posted May 16, 2019 Share Posted May 16, 2019 I'd first look at range and or interference. What happened locally in the build up to the fault. Also have you tried temporarily relocating the keypad and power cycling Quote Link to comment Share on other sites More sharing options...
PJR2534 Posted May 17, 2019 Author Share Posted May 17, 2019 Thank you for your reply. Nothing unusual happened and nothing new has been installed locally. The environment hasn't changed as far as I can tell to cause any interference. The alarm was set using the keypad in the morning but was displaying the "No Communication" message when trying to disarm the alarm later that afternoon. I have replaced the batteries in the keypad and power cycled the control box with the keypad adjacent to it but with the same result. The keypad initially indicates "<updating>" but then very quickly reverts back to "No Communication" Quote Link to comment Share on other sites More sharing options...
Secware_Tech6 Posted May 17, 2019 Share Posted May 17, 2019 It does sound like there is an issue with either the keypad or the panel then unfortunatly Quote Link to comment Share on other sites More sharing options...
