Hi installed a Yale HSA 6400 alarm system on April 2016 .Everything was fine. Two days ago the control panel beep every 30 seconds and the amber (yellow ) light is lit. Any message on the panel need to change battery. Check the door contact and PIR fine . Alarm working fine. I disconnect the power for few minutes and power on still a amber on panel. Please help.
