Know the moment.

The GRI 4400-A is an industrial surface mount switch set built for monitoring a door, gate or access point on commercial and industrial sites. It uses a normally open, closed loop contact with a 2-1/2″ standard gap and comes with 36″ of armored cable, and the aluminum housing suits installers who need a more rugged option than a standard residential contact.
Brand: GRI
Model: 4400-A
Type: Industrial surface mount switch set
Gap: 2-1/2″ standard
Rating: 10W, 200VDC, 0.50A
Circuit: Closed loop, N/O

Mount the switch and magnet on the frame and moving door or gate so they stay aligned and within the rated gap when closed. Run the armored cable clear of moving parts, secure it along its length, and test the loop on the alarm panel after mounting.
