The Ei261ENRC is a Carbon Monoxide(CO) alarm powered by 230V AC mains power, and has built in tamper proof rechargeable Lithium cells that act as a battery back up in the event of mains failure.
These rechargeable Lithium cells are designed to have a ten-year life and outlast the life of the CO alarm.
They will provide up to 4 weeks of CO alarm operation without mains power.

The Ei261ENRC also has Remote Control capability - allowing the alarm to be controlled remotely from a Control Switch (Ei1529RC).
This then allows remote Test, Locate and Hush functions to be performed.

If the Ei261ENRC is also interconnected to other Ei "RC" mains powered alarms, then the whole system can be controlled remotely.

Up to twelve alarms can be interconnected.

A Manual Call Point (MCP401RC) is also available.

The Ei261ENRC is supplied with an Easi-Fit base that allows very quick and simple installation of the alarm, combined with simple removal and replacement.
The Easi-Fit base automatically connects both mains power and battery as the alarm slides on to the base.

The Ei261ENRC uses a high performance electrochemical sensor to sense CO presence.
The sensor can be replaced after 5 years to provide a combined 10 year protection against CO gas.

The Ei261ENRC has built in circuitry to aid suppression of voltage transients and RF interference to further reduce the chances of false alarms.
