i have a customer with 2 out of 4 keypads that have a 7 sec. delayed response when buttons are pressed. they have the most current software version9.2. its a delay on and a delay off response. any ideas? ive checked fade rate and delay setting but both are set at 0. total of 23 devices including 3 aux repeaters and 1 main repeater. keypads in question are within 30 feet of repeater.
