The Honeywell 3/4 inch Recessed Hardwired Sensor with Leads connects to a wired alarm control panel to protect any door or window. Unlike the Recessed 3/8″ Hardwired Contact with Screw Terminals which uses terminal screws to connect to the contact loop wire, the 3/4 inch Recessed Hardwired Sensor with Leads has wire leads which you must splice to your contact loop wire, using a wire connector. Typically a hardwired zone is wired with 22 gauge wire with 2 conductors (also known as 22/2 wire). Each includes wire crimps to help with your wiring connections. In addition, it uses an internal reed switch with a rating of 100mA at 28VDC.

In order to install this sensor; you must drill a 3/4” diameter hole into the frame and door or window. Also that is at least 1.5” in depth. And match up to each other when the window or door is closed. The contact is then recessed into the door or window frame, and the matching magnet is recessed into the door or window itself, opposite the contact. Hardwired should be installed in an area with a gap no wider than 3/4” to ensure that contact is made when the door or window is closed.

Features:

• 3/4″ Diameter recessed contact
• Standard gap: 1/2″ end to end, 3/4″ parallel
• Convenient 5′ zip cord leads are standard
• Press to fit design is quick and easy
• 3/4″ diameter switch with 3/8″ magnet
