George Risk Industries 180-12-BL Recessed Door Contact

Product Description

The George Risk Industries 180-12-BL is a recessed door contact designed for use in security and alarm systems. This steel-bodied contact installs flush into a drilled hole in a door or door frame, keeping the sensor concealed and out of view. When the door opens, the circuit state changes, signaling the alarm panel or access control system. The black finish blends with dark-colored door frames and trim. It fits a standard 3/4-inch diameter bore, making it compatible with common installation tooling used by low-voltage alarm and security technicians.

This recessed contact is suited for residential and light commercial door and window applications where a concealed sensor is preferred over a surface-mount style. Typical installations include entry doors, interior access doors, and hinged panels in security systems. The steel construction provides durability in high-cycle door applications. Low-voltage alarm installers and security system technicians are the primary trades that specify and install this type of component.

• Recessed mount design keeps the sensor concealed within the door or frame

Installation Notes

Installation is typically performed by licensed low-voltage alarm or security technicians. De-energize the alarm panel or access control circuit before wiring the contact leads. A 3/4-inch spade bit or Forstner bit is required to drill the recess in the door and frame. Follow local low-voltage wiring codes and the alarm panel manufacturer's wiring guidelines when terminating leads.
