I had an issue today with the alarm sounding when not set. The panel said tamper and a zone number. This relates to the pir on the stairs. I entered the user code which cleared it but then when motion was detected the tamper alarm sounded again. It has now settled but I am worried this could trigger again. Does this sound like a faulty pir? Or should I check anything else first. I have asked a few local companies for prices but thought I would check if this was a common fault.
 

The pir is labelled Saturn

 

also any recommendations for a replacement sensor if this is required.

 

Thanks

Thanks for the replies. This has been fine since June and then suddenly started happening again last night.

How would I go about checking the wiring? Or would you replace the pir first? The sensor looks ok and the tamper switch seems fine...

 

Any particular sensors that work ok with the scantronic 9930?

9930 is a keypad,

 

the controls will either be DP or FSL

 

any DP sensor can have resistors fitted,

 

The tamper will be the controls, cable or the device

 

low Ω's on a multi meter for the cable ect..

Yea I have a multimeter and can probably figure out which resistance setting etc to put it on. Although the more basic the instructions the better ?

Are there resistors in the PIR? Or wires just striaght into the tamper and alarm terminals?
