So I added a wired PIR in the basement today, had to swap some wireless zones free up some space, anyways all good with the zones I was working with. Then about 45 minutes later everything in the living room turns off. PLEG doing it because zone 1 (PIR) hasn’t tripped. Did my basic troubleshooting, device good, wiring good, the board however seems to be throwing up some flags.
No wiring connected i read a short between zone 1 and common. How could it sense anything with no resistive load on it all at? Checked zone enabled defined and attributed correctly. Even swapped zone 1 and 2 both motions to make sure meters was accurate. Problems stays with zone 1.
Anyone got any ideas?
Maybe try moving it to another zone on the board. Maybe at the end just to make sure there is nothing wrong with the wiring and sensor.
Recently, I was having trouble with my Zone 1. This is hooked up to a wired NC 3/8" sensor on my front door. I ended up figuring out that the 2 parts of the sensor weren’t lined up. Seems like the wind would push on my door just enough to make it lose connection for a second. I drilled the sensor out of door and repositioned it and it’s been working great ever since.

Are you sure that the panel sees zone 1 as a short???
Is the zone configured for supervision?? If it is, the lack of connection between Z1 and common (open circuit) will show as a trouble or a tamper, as the panel expects to see a resistance on the circuit when the sensor is tripped. An EOL resistor is required in this case.
Since the problem did not move to zone 2 when you swapped them, then zone 1 is probably not programmed correctly.
check sections
[013] Opt [1] Selects Normally Closed or EOL resistors? [013] Opt [2] Selects SEOL or DEOL resistors
I think Brientim is on to it. The DSC has to be told whether the loop is simple open/closed or resistive terminated (supervised) and whether the resistor is at the remote end or the near end. If you swapped out a wireless sensor for wired at that zone then you should check to make sure that DSC has the right termination configuration for the new sensor
Thanks for all the replies. I changed another zone, not zone 1 from wireless to wired. Zone 1 is a PIR which is behaving as it should. My panel is set up for NC loops, no supervision, zone is enabled, 000000 for ESN, wireless disabled, same attributes and definitions as a functioning zone 2 PIR.
2 things just popped into my head and I will google later if no replies, how do i make sure zone 1 isn’t set up as a wired zone from a keypad and how do i know its not on a separate partition?
My temp solution was to series zone 1 and 2 PIRs, works but my PLEGs are less accurate due to less detectors.
I’m not really sure what the panel “sees” electrically. I disconnected all the zones and some seems to be open between the zone and common and two are. Zone 1 and zone 7. 7 is wireless so no physical device connected, and I’m still at a loss as to whether its a bad zone or bad programming.
