Product Information
The Kidde K4MCO is a 230V mains-powered carbon monoxide alarm with a sealed rechargeable lithium back-up. If the mains supply fails, the back-up keeps the alarm working for at least 72 hours. It uses an electrochemical sensor and is certified to EN 50291-1. It suits homes, rented properties and other buildings where fuel-burning appliances are installed.
The alarm can be interconnected with other Kidde and Firex mains smoke, heat and CO alarms using Smart Interconnect, so one detection triggers the whole system. Up to 24 other devices can be linked. A tamper-resistant lock means the alarm cannot be removed without a tool. The test/reset button lets you check it and silence it.

Frequently Asked Questions
Fit one in every room with a fuel-burning appliance, typically 1 to 3m horizontally from the appliance. On a wall, keep it high but at least 150mm below the ceiling. On a ceiling, keep it at least 300mm from any wall. Avoid bathrooms, garages, areas next to cooking appliances, and positions near extractor fans, doors and windows. Check the manufacturer's instructions for the full siting rules.
The user guide calls for PVC/PVC cable such as 6242Y, or 6243Y where interconnection is needed, or an equivalent that meets local regulations. Live goes to brown, neutral to blue, and the interconnect to the white wire. Never use the earth conductor for interconnection. All linked alarms must be on the same circuit, with up to 300m of wire run between the first and last unit.
It can be linked to other Kidde and Firex mains smoke, heat and CO alarms that use Smart Interconnect, up to 24 other devices, 18 of which can trigger an alarm. It is not designed to work with other manufacturers' alarms. Check the manufacturer's instructions and the compatibility list for the alarms already installed before mixing models.
It needs a constant, unswitched 230V AC supply. Inverter sources with square-wave or modified sine-wave output are not suitable. The building installation must include a means of all-pole disconnection. Installation should be carried out by a competent person in line with current wiring regulations and the manufacturer's instructions. Before connecting, slide the battery switch on the back to on.
