How do I change the batteries in the PIR sensors for I-on16 alarm?
I need to change the batteries in the PIR sensors but when I try to remove the front of the sensor it sets the alarm off. I assume I need to put it in a certain mode but can't work out which one. Any help greatly appreciated. Thanks Max
all you need to do is key in your pin number to silence the alarm,fit batteries then key in ur pin number to reset,the panel will go back to green square
