Product Description

The Ei204EN is a Carbon Monoxide (CO) alarm powered
by 9V battery power (supplied by 3 x AA alkaline
batteries). The CO alarm is housed in an attractive
slimline casing and can be easily secured to a wall or
ceiling – the fittings are supplied

The 204EN CO alarm uses a proven electrochemical cell
type sensor which checks CO concentration every 50
seconds. All units are individually calibrated and tested in
CO gas in order to ensure accuracy.

An easy to use Test/Hush button allows the user to
check that the horn and electronics are working and to
silence nuisance alarms

Operation

The green indicator will flash every minute to

indicate that the 9V battery supply is working

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 flash

every minute to indicate a fault

The horn will beep and the green indicator flash

every minute to indicate that the batteries are
depleted

On power up the green, red and amber lights each

flash once – after 20 seconds, the green light
flashes every 4 seconds. At the end of the warm up
the red light flashes once

BATTERY POWERED 9V
