  1. I've finally gotten round to putting the recessed door contact (Knight A51MULTI G2) for the entry/exit rather than using the hallway PIR. I wired everything up and re-enabled zone 1 but it was displaying tamper. So I stripped back the contact and tested all the resistances 2.2 secure, 6.9 active, 1/0 tamper. I also checked the resistances at the alarm box to make sure I didn't have a break in the cable. To confirm I linked the contact circuit into Zone 6 which was spare and wintex diagnostics registers 2.2 secure (healthy). Finally to confirm Zone 1 I bridged and programmed zone 1 to always closed which returned an active state (unhealthy) Does it sound like Zone 1 is dead and I need to replace the board or could it be a common faults that can be rectified without a board replacement?
