Quote:I was short all zone and test system is ok what is the problem of zone troubling.
You mean you removed the zone wiring from the zones, and there is no zone trouble
That proves that the problem is in the wiring or the sensors.
There is a voltage on the wires
Next re-connect the wires, use a multimeter to measure the voltage from Zone to Common (center pin on the terminal block)
The zone shunt should be closer to the terminal block
measure the voltage with the sensor closed. It should be 0 volts
measure the voltage with the sensor open (ie door open). It should be around 1.3 volts
These are the voltage when there is no other voltage sources on the wiires
Let me know what is the voltage you measure on the affected zones
