Faulty PIR For Aritech CS350

brickyard

Hello Folks,

Anybody experience a situation where a PIR in a conservatory has started alerting only when it is very sunny? I can set the alarm without any issues, and if weather remains overcast then all is OK (partial set at nightime is also OK) - issue only appears when it is particularly sunny. Is this indicative of a faulty PIR?

If so do I need the the engineers code for above system to change the PIR and how is it possible to get same - default codes do not seem to work?

Any help appreciated,

PIR in a conservatory

Thats the problem, replace it with dual tech

Hi JNealon,

Thanks for the reply. As far as I am aware this is a dual tech PIR - it has been working for years without any issues.
I'm not familiar with intruder systems but would suppose that these units do go faulty after a period of time, or is this a lazy assumption?

You may have a faulty pir if that is the case. You do not need the engineer code if you are replacing the pir with another pir. If you needed to change settings in the panel you would need the code. Just be careful not to cross the 12v power when changing the pir out. If you do it is only a matter of replacing the fuse in the panel. If you wanted you could also disconnect the 12v in the control panel to prevent this from happening. There is a diagram on the back lid of the control panel so you know what you are disconnecting. Just make sure you turn off the mains as there is live mains in the control panel. The system will still work on the battery while the mains is off.

Sounds like the you have a faulty detector.
Replace it with another DT detector. Honeywell would be a good brand to look for

altor/Jnealon,
Thanks for the replies. I will source a new PIR. One further query on this please, will the system "remember" the settings for this zone/PIR or will it have to be re-programmed?
Many thanks again.

The settings will remain. They can only be changed in engineer or by defaulting the system.
