I have two Iris v2 keypads and one Iris v3 keypad. My v2 keypads work as intended but whenever I enter my code to disarm the v3 keypad, HSM is set to off but the v3 keypad still beeps like it is in the delay even without a contact sensor being opened. I have them all to their respective drivers and I think this started after the latest update...
Mine does the same. Everything disarms, but the keypad has a series of rapid beeps for a few seconds after that. This occurs whether in delay mode or not.
