Kidde Edwards 1078C-M Recessed Magnetic Contact Switch

Product Description

The KIDDE EDWARDS 1078C-M is a recessed magnetic contact switch designed for door and window perimeter protection in security and fire alarm systems. The unit installs flush into a 3/4-inch diameter bored hole, keeping the sensor concealed within the door frame or jamb. When the door or window opens, the magnetic field breaks and the switch triggers the connected alarm or access control circuit. Licensed security technicians and low-voltage alarm installers are the primary trades that work with this device.

The 1078C-M is suited for residential and light commercial security installations where a clean, concealed appearance is required. Recessed contacts are commonly specified in new construction and retrofit projects where surface-mount hardware is not acceptable. The switch is sold as a single unit and is intended for use with a matching magnet installed on the moving door or window panel to complete the magnetic circuit.

Key Features

• Recessed form factor installs flush for a concealed, low-profile appearance
• 3/4-inch diameter body fits standard bored installation holes
• Magnetic reed switch operation with no moving external parts
• Compatible with typical perimeter detection circuits in security and fire alarm panels
• Single-unit packaging for straightforward replacement or new installation

Compatibility

Designed as an OEM-style recessed magnetic contact switch for use in door and window perimeter detection circuits on residential and light commercial security or fire alarm systems.

Installation Notes

Installation is performed by licensed low-voltage security or fire alarm technicians in accordance with local codes and NFPA 72 requirements where applicable. De-energize and disarm the alarm panel before wiring the contact to avoid false activations or panel faults. The switch requires a matching magnet mounted on the door or window leaf, aligned within the manufacturer-specified gap tolerance for reliable actuation. Drill the mounting hole to the correct 3/4-inch diameter to ensure a secure, rattle-free fit.
