Protecting Wood or Steel Doors with Roller Plunger Contacts
Wood and steel doors can be protected with roller plunger contacts that can be installed without removing the door from its hinges. The versatile Sentrol 3005 and 3008 Roller Plunger Contacts can also be used on windows and sliding patio doors. Roller plungers are more versatile than plunger switches, which work in limited applications. The 3008 is designed specifically for fight, thin-framed window and door applications.
Roller plunger Interlogix switches can also be used to protect high-value objects such as antiques, rare books, or works of art by placing the object on the recessed contact.
Note: In order to comply with UL installations, the contact should not be used on exterior doors that open outward.
The roller plunger contact must be mounted on the hinge side of the door or window to be protected.
Open the door or window. Drill a 3/4" (1.9 cm) diameter hole in frame. Hole should be 1.5" (3.81 cm) deep for the 3005 and 3/4" (1.9 cm) deep for the 3008.
Run wire through the frame and connect switch to the alarm loop. Insert switch in hole and test for proper operation by opening door or window.
Screw switch in place.
