Harness

Wiring harnesses and interconnect assemblies for fire alarm panels — the pre-terminated cable sets that link a panel's boards, power supply, display and expansion bays.

These are panel-specific by design. Connector type, pin count and length are all matched to a particular panel and bay configuration, so ordering by the panel model and the existing part number is the only reliable route. Replacing a harness with a hand-made equivalent is not a listed repair.
