The Ei225E is a mains powered Carbon Monoxide (CO) alarm. 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 EI225E 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 to ensure accuracy, which are covered by a lifetime - 5 year guarantee.
As well as being easy to install and maintain, the alarms have a vitally important memory feature which records if CO has been detected whilst the occupier was away.
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 light to indicate that the mains power 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 45 seconds to indicate a fault
The pre-alarm feature will flash the red light every 5 seconds if the alarm detects over 50ppm of CO gas
Memory Feature - when the test button is pressed the horn will sound and the indicators flash to indicate CO has been previously detected: red light off - no CO, slow red flash - 150ppm detected, and fast red flash - 350ppm detected

Installation & Placement
To mount onto a wall or ceiling, simple remove the cover and mark the position of the two mounting holes. Drill two holes using a 6mm drill for the plastic plugs (supplied) and screw the unit home with the screws supplied.
If locating the CO alarm in a room with an appliance
the alarm should be located between 1m and 3m horizontally from the appliance and between 1.85m and 3m from the appliance
the alarm should be located preferably on the ceiling, at least 300mm from any wall
if placed on a wall, the CO alarm should be as high as possible but not within 150mm of the ceiling
If locating the CO alarm in a room remote from the appliance
the alarm should be located at a level similar to the breathing zone of the occupant (typically 1.5m to 2m above floor level and in bedrooms at the height of the bed)
