I have a siren based Yale Alarm system. I recently changed the batteries. However, now when I set the alarm although it beeps to say it is armed the PIRs no longer flash red or set off the alarm. Any tips?

Was definitely working beforehand. Batterues definitely working okat as it goes off when tampered with. Thanks very much though.

Thanks I will give that a try also. Would it not be very strance for it to work for several years without issue then not work after battery changed?

We have had a yale alarm for a number of years. Having changed the batteries in the box PIR movement detectors this week one of the PIR is no longer linked to the alarm. It still flashes at movement and sets off alarm if I 'tamper' with it. However, it does not set of the alarm or beep if I walk...

Great response time. Do you know anything about yale alarms?
