Rixson 972S

Rixson® electromagnets are designed for virtually any remote door release application. They are primarily used to hold fire and smoke barrier doors open until released by a remote smoke detector or other switching device. Them complete assembly consists of an armature contact plate with adjustable pivot mounting for installation on the door, and a heavy-duty electromagnet mounted on the wall or floor behind the door. A separate closing device is required.
The Rixson® 972 Industrial Door Release is listed by Underwriters’ Laboratories as a substitute for fusible links in such applications as overhead rolling doors, guillotine doors, fire dampers and self-closing windows. These heavy-duty units provide positive latching and automatic release when triggered by a smoke detector, manual pull station or other lectrically operated switch.
