Macurco 78-2900-0046-8 Wire Harness 8 Pin CM-E1

Product Description

The MACURCO 78-2900-0046-8 is an 8-pin wire harness designed as an internal wiring component for the CM-E1 carbon monoxide detector. This harness connects the printed circuit assembly (PCA) to other internal components, maintaining reliable signal and power continuity within the detector housing. It is a direct OEM-style replacement part intended for service technicians performing component-level repairs on MACURCO carbon monoxide detection equipment. Proper harness integrity is critical to accurate CO sensing and alarm function.

This wire harness is used during repair or refurbishment of the MACURCO CM-E1 carbon monoxide detector, a unit commonly installed in residential and light commercial occupancies including garages, parking facilities, and mechanical rooms. Technicians performing board-level service or replacing a damaged PCA will typically need this harness to restore full electrical connectivity within the unit. It ships as a single assembly.

Key Features

• 8-pin connector configuration matches OEM CM-E1 PCA layout
• Direct replacement harness for component-level detector repair

Installation Notes

Installation should be performed by a qualified technician familiar with carbon monoxide detection equipment. Disconnect power to the detector before removing or reseating any internal wiring. Handle the PCA and harness connectors carefully to avoid pin damage or connector housing stress. Verify all connections are fully seated before restoring power and testing detector function.
