George Risk Industries GI-E18012B Recessed Door Contact Switch Set

Product Description

The George Risk Industries GI-E18012B is a recessed door contact switch set designed for use in security and access-control applications. This switch set mounts inside the door or door frame, concealing the sensor for a clean installation. When the door opens, the magnetic contact breaks the circuit, triggering the connected alarm or monitoring panel. The unit is sold individually and is suitable for steel door applications where a flush-mount, low-profile sensor is required. Security installers and electricians working on commercial and residential intrusion-detection systems are the primary trades that handle this component.

This recessed contact switch set is used in door-frame installations on steel doors across residential and light commercial security systems. It fits into a bored hole in the door or frame, keeping hardware hidden from view. Typical applications include perimeter zone sensors on entry doors, emergency exit monitoring, and access-control points where surface-mount contacts are not acceptable. The bagged, individually packaged format suits service-call replenishment and single-point replacement work.

Installation Notes

Installation is typically performed by licensed security technicians or electricians familiar with low-voltage alarm wiring and applicable local codes. De-energize the alarm panel zone before wiring the contact leads to avoid false triggers or panel faults. The recessed bore diameter and depth must match the switch set dimensions before installation. Follow the panel manufacturer wiring guidelines and consult NEC Article 725 requirements for Class 2 low-voltage circuit wiring.
