Hello,
This morning upon leaving my house, I notice that the keypads did not have any display present and none of the PIRs flashed as I moved across them.
A check of the main panel show that the back up 7ah lead acid battery had failed (no warning from Comfort). It appear to be dragging down the boards power supply. When I disconnected the battery, the output from the traffo to the board was restored to 14v approx. But I still had no 12v supply to the zones or the keypads. I reset the board and the leds do their sequence until the green flashes on/off slowly. None of the power components and heat sinks are hot.
When I used the local phone, Comfort tells that 'Communications Failure 66, and then goes on to list the main menu.
Do I need to replace my backup battery before the system will output the 12v to power the keypads and zones.
Do I have a short on one of the 12v outputs to the PIRS??
Any other things I can check..I really need to get this system back and running.
