PIR light on the house alarm stays on permanently on one of the zone?

[Kingkat]

PIR light on the house alarm stays on permanently on one of the zone (zone 2 - lounge)

When trying to set the alarm, the zone 2 - lounge light stays solid & keeps bleeping continuously on the alarm panel, just won’t set?

I’ve to omit the zone 2 - lounge from the alarm panel to get the rest of the zones working & able to set the alarm?

 

I’ve also opened the alarm panel up, disconnected the zone 2 wires (blue & yellow) to see if the rest of the alarm zones works without having to omit zone 2, It didn’t work so Is there a specific way of doing this?

 

Also forgotten which way the blue & yellow wires goes back, does it make any difference if the blue on the left, yellow on the right or vice versa when connecting it back to the zone 2 terminal blocks on the alarm panel?

I’ve also replaced the alarm panel old battery with a brand new one so maybe replacing the PIR should solve the issue?

No makes no difference. Sounds like a failed detector

[Kingkat]

 

I’m looking at the Honeywell IS312B as a replacement for the old failed PIR detector (similar size, good price & reviews)

 

The old PIR has 6 wires connected to the terminals:

T, T, N, C, -, +

 

The Honeywell IS312B terminal connectors:

T2, T1, NC, N, V-, V+

 

I presume it also makes no difference on the Honeywell IS312B, how the T2, T1 (vice versa) & NC, N (vice versa) when wiring it up?

No

What voltage have you got on the 12v aux? When was the last time it was serviced? when was the battery last changed. If the battery is pulling the voltage down this could be causing not enough voltage reaching the detector which could be your problem 

[Kingkat]

The battery was changed aprox 6 months ago, don’t think it’s the battery as it’s relatively new.

 

The PIR is quite old, alarm system installed originally by house builders so my gut feeling it’s most likely the PIR is faulty 

 

I’ll replace the PIR & if this doesn’t solve the issue, I’ll get a tradesman to service/repair the alarm system.

Probably is the detector, however, Id still be checking what voltage you have at the detector, if the battery was not replaced before it failed it could have damaged the charging circuit. Especially if the panel is as old as the detector.
