AAADM Inspection

Automatic door systems should be checked annually by an inspector who has been certified by the American Association of Automatic Door Manufacturers. Through that annual inspection, the door system can be checked for compliance with the latest industry standards. Also, automatic door systems should be given a daily safety check by premises owners. The American Association of Automatic Door Manufacturers provides details on how to conduct a daily safety check. Premises owners can use this guide to train or retrain employees to perform the daily safety checks properly. That helps assure safe operation of automatic doors. Additionally, all new sensors on pedestrian openings should also be properly adjusted by an AAADM certified inspector. If you are not a reseller or AAADM Certified, please contact us and we can provide you a list of local AAADM certified inspectors who can accurately make these adjustments to your new sensor(s). When properly installed, inspected annually by AAADM certified inspectors and safety-checked daily by premise owners, automatic doors consistently provide safe, convenient access for everyone.
