Security Door Controls of Westlake Village, California, has introduced a new emergency door release with an internal alarm. The SDC emergency door release pull station provides immediate unlocking of one door or all doors on the same circuit, while providing local annunciation. The use of the door release can influence the approval of a locking system installation. The product features 2-SPDT dry contacts, an internal alarm, and a blue finish that is not confused with fire alarm stations. Auxiliary contacts can be used for remote annunciation.
