I have a centralite keypad XHK1b(the one with A and B button at the button and use AA battery). It paired with HE without any problem. However, when I changed the HSM to arm night using anything other than the keypad. The keypad will beep indefinitely unless HSM is changed to other HSMs. This does not happen when the keypad is used to changed HSM to night sleep. There was a post in the past but did not seem like there was a solution posted.
Please help. I don't know if anyone can use this keypad with HE since if will keep beeping non stop.
