George Risk Industries Inc. 4704 Surface Mount Spdt Contact

Product Description

The GEORGE RISK INDUSTRIES INC. 4704 is a surface mount jacketed cable single-pole double-throw (SPDT) contact designed for security and access control applications. This pull-apart style contact operates by breaking or making a circuit when two mating sections are separated, triggering an alarm or control signal. It is typically installed by security technicians and low-voltage electricians on doors, windows, or access panels where concealed or semi-concealed wiring is preferred. The jacketed cable construction protects the lead wires from abrasion and environmental exposure, making it a durable choice for light commercial and residential installations.

The 4704 is suited for surface mount installations where recessing into a door frame or jamb is not practical. It fits common applications such as perimeter door and window monitoring on security alarm panels, access control systems, and building automation inputs. The pull-apart design allows for clean, reliable circuit interruption each time the protected opening is actuated. Installation is straightforward on standard door and window frames without specialized tooling.

Key Features

• Surface mount design installs directly onto door or window frames without recessing
• SPDT switching provides both normally open and normally closed circuit outputs
• Pull-apart contact mechanism for reliable door and window monitoring
• Jacketed cable lead wires resist abrasion and physical damage
• Compact form factor suitable for residential and light commercial security systems

Compatibility

Designed as an OEM-style surface mount SPDT contact for use in residential and light commercial security alarm and access control systems. Part of the 4704 and 4714 series pull-apart contact family.

Installation Notes

Installation is performed by licensed low-voltage technicians or security alarm installers in accordance with applicable local codes and NFPA 731 guidelines. De-energize the alarm panel or control system before making any wiring connections. Secure the contact halves to their respective mounting surfaces so that normal door or window operation produces consistent circuit actuation. Avoid routing jacketed cable leads near sharp edges or pinch points that could damage the insulation over time.
