The reboot signal is controlled by the same prompt that controls the low battery reporting. To turn this prompt on:
With D5200 programmer:
1. Receive a copy (RECV/COPY) of your 6112/5503 panel onto your 5200 programmer. After you see Receive Successful continue to step two.
2. Press the red ENTER GROUP key on the D5200 keyboard to enter module 1 Globals.
3 Using the red down arrow key scroll down til you see Batsupv and put a 9 in this prompt or a value from 0-9 or B-F(this is the signal that is reported to your central station) then press the white enter key on the 5200 keyboard.
4. Now press the red SEND(LOAD) key on the D5200 keyboard.
5. Disconnect the programmer cord from the cpu board and perform a Reset(to the right of zone 8 there is a metal post labeled Reset, momentarily short this post to TB3 below it or any panel common). The panel should now dial out the system reboot.
