Presence Safety Sensors

E-3090 MS Sedco DH400 Active Infrared Presence Sensor

The DH400 is a high mount active infrared presence sensor designed to provide both activation and safety protection for automatic sliding and folding doors. The DH400 is based upon the most reliable active infrared (AI) technology available—Floor Reflection Method (FRM). With FRM-AI up to 60 individual detection zones (floor points) are precisely reflected off of the floor in a rectangular pattern meeting and exceeding ANSI A156.10 guidelines. The DH400 provides detection as far as 13.1 feet (4m) from the door while simultaneously providing a dense zone of presence detection at the threshold of the door. With a sensing area made up of 60 separate detection zones, the DH400 provides the highest density pattern available. (Supersedes prior units D14-1, D14-2, DH97, DH94D and DH98i)

  • Frm-ai (floor reflection method active infrared) detection
  • Mount up to 13.1′ (4m) high
  • Width and depth of detection pattern is fully adjustable
  • Easy to install and adjust

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.
