George Risk Industries 8709HP Surface Mount Contact Set

Product Description

The George Risk Industries 8709HP is a surface mount contact set used in security and access control systems. It combines a contact body with a matching actuator magnet to detect door or window position, signaling an open or closed state to the connected control panel. The 8709HP references the 4402A contact and HSR634WT actuator as its primary components. This type of device is installed by security technicians and low-voltage electricians in both residential and commercial applications where reliable, tamper-evident sensing is required.

The 8709HP is suited for surface mounting on doors, windows, hatches, and access panels where a recessed or flush-mount installation is not practical. It is commonly deployed in intrusion detection systems, fire alarm auxiliary circuits, and access control loops. The surface mount form factor allows for straightforward installation on metal, wood, or composite frames without drilling deep cavities into the frame material.

Key Features

• Surface mount design allows installation without recessing into door or window frames
• Combines contact body (4402A) and actuator magnet (HSR634WT) in a single set
• Suitable for use in intrusion detection, access control, and auxiliary alarm circuits
• Sold as an individual set (quantity per unit: 1)

Compatibility

Designed as an OEM-style surface mount contact set for use in low-voltage security, alarm, and access control wiring applications.

Installation Notes

Installation should be performed by a licensed low-voltage technician or security system installer in accordance with local codes and NEC Article 725 for low-voltage circuits. De-energize the control panel circuit before making any wiring connections to the contact leads. Mount the contact body and actuator magnet in alignment on the stationary and moving frame surfaces so the gap between them falls within the specified operating range for the device. Verify proper signal output at the control panel after installation before closing up the work area.
