The INTERNATIONAL COMFORT PRODUCTS 21006406 is a wire-in carbon monoxide alarm designed for hardwired AC/DC installations with interconnect capability. This unit connects directly to a structure's electrical system and can be linked with other compatible alarms so that when one detects CO, all interconnected units sound simultaneously. It is suited for residential and light commercial installations where continuous, line-powered CO detection is required. Licensed electricians and HVAC technicians routinely install this type of alarm as part of system commissioning or code-compliance work in occupied structures.
This alarm is appropriate for use in residential homes, apartments, and light commercial buildings where CO detection is mandated by local building or mechanical codes. Wire-in alarms of this type are commonly installed near sleeping areas, mechanical rooms, and attached garages per code requirements. The interconnect feature makes it a practical choice for larger floor plans or multi-level buildings where a single alarm point is not sufficient to alert all occupants.
Designed as an OEM-style replacement or new-installation wire-in carbon monoxide alarm for use in hardwired, interconnectable CO detection systems.
Installation should be performed by a licensed electrician in accordance with local electrical codes and the National Electrical Code (NEC). Always shut off power at the circuit breaker before making any wiring connections. Follow the manufacturer's wiring diagram for AC/DC and interconnect terminals, and verify proper operation of all interconnected alarms after installation is complete.
