Hi , Ive just installed a new Yale wireless alarm which works great , but can’t seem to find out what the red buttons are for on the small wireless keypad?. They are called ‘panic alarm a & b’. I understand why there might be one , but two?
I don't know that model. Is the keypad described in
edit
can't see an instruction manual on their website.
I have an idea that on one of their models, you press both panic buttons together (to reduce the risk of it going off by mistake if you just press one)
it used to be better if they were aimed to capture someone after they had come through the door and were walking down the hall, so they were not activated at the same time as the door sensor, as the radio signals may interfere with each other. Your model may be different. They work better when somebody walks past or across the PIR sensor, rather than towards it.
I don't know about the letter box. Mine is beside the front door and points away from it.
