I have the PC5132-433 (wireless receiver)
I have the PC5010 board
I have the basic 8 zone LED keypad.
I have one wireless door contact sensor and a wirless smoke detector. The batteries in each appear to be fully charged.

I recently replaced the main panel backup battery.

When I do a *2, the zone 7 & 8 lights come on. I can fix the zone 8 (date and time problem), but I am confounded by the zone 7 trouble problem.

When I press 7 again, no zone lights come on.
When I press 7 again, no zone lights come on.
When I press 7 again, zone light 2 comes on.

The manual states that this indicates Wireless keys with low batteries. Here's the weird part I don't have any wireless keys.

Any help would be greatly appreciated.

 

It is not unheard of for the programming on DSC panels to get a little scrambled if the system runs on a failing battery. If you have no wireless keyfobs for this system, and never had, then you may need to go into the wireless reciever programming and delete the phantom device.

(Note: according to the manual for the wireless reciever; you need to power down and restart the system for a deleted wireless device trouble to clear.)
