Product Description

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.

Operation

The green indicator will illuminate to show mains power is

present

The horn will sound and the red indicator will flash at

different speeds to indicate the presence of various levels of
CO gas – slow flash indicating low levels and rapid flash to
indicate high levels

The horn will beep and the amber indicator will flash every

40 seconds to indicate a fault on the sensor

The horn will beep every 40 seconds to indicate a the

battery back up is depleted and needs recharging

The “Test/Hush” button will either silence false alarms (if

briefly pressed) or perform a unit self test (if pressed and
held). Note that the alarm cannot be silenced when sensing
a CO level of 300ppm or above

Memory Feature – after the unit has been in alarm, the red

indicator will flash every 40 seconds at a rate indicating the

CO level previously detected. Pressing the “Test/Hush”

button will also cause the red indicator to flash at a rate
specific to the previously sensed CO level.

When interconnected to other Ei mains powered alarms, an

alarm on one detector will trigger all other interconnected
alarms (only the triggered alarm will flash a red indicator)
