Kidde Edwards KC2-RB 2-wire Relay Base Ul Ulc

Product Description

The KIDDE EDWARDS KC2-RB is a 2-wire relay base designed for use with compatible detector heads in fire alarm systems. The relay base provides switching capability directly at the detector mounting point, allowing field wiring to control auxiliary devices such as door holders, fans, or dampers when a detector activates. It is installed by licensed fire alarm technicians during new construction or retrofit projects and carries both UL and ULC listings, confirming it meets North American safety and performance standards for fire alarm accessories.

The KC2-RB is suited for commercial and residential fire alarm applications where a relay output is needed at the detector level without running additional control wiring back to the panel. It mounts in place of a standard detector base, keeping the installation compact and code-compliant. The 2-wire configuration simplifies wiring on conventional and some addressable fire alarm loops where base-level relay control is required.

Key Features

• UL and ULC listed for use in North American fire alarm installations
• 2-wire relay configuration reduces wiring complexity at the detector location
• Integral relay switches auxiliary loads directly from the detector base
• Sold as an individual unit for single-point replacement or new installation

Compatibility

Designed as an OEM-style relay base for use with compatible KIDDE EDWARDS detector heads in 2-wire fire alarm system configurations. Consult the product data sheet and system documentation to confirm detector head compatibility before installation.

Installation Notes

Installation must be performed by a qualified fire alarm technician in accordance with NFPA 72 and all applicable local codes. Disconnect and lock out power to the fire alarm control panel before removing or installing any base or detector. Verify that the relay contact ratings are appropriate for the auxiliary load being controlled before wiring. Follow the manufacturer data sheet for base wiring terminations and detector seating procedures.
