The Ei208 is a Carbon Monoxide (CO) Alarm that is powered by
a sealed-in Lithium battery.
The alarm has a high performance, proven electrochemical
sensor to sense CO presence. The sensor is individually
calibrated and tested in CO gas on assembly to ensure
The alarm has a twist on mounting base which has multiple
fixing points so it can easily be secured to a ceiling or wall.
The memory feature records the last CO level sensed and can
be useful to check if CO has been present if the home owner
or tenant has been absent from the property.
An easy to use Test/Hush button allows the user to test the
alarm. This checks all aspects of the alarm (sensor, electronics
The alarm has an ‘End of life’ indicator which will notify the
user when the alarm needs replacing at the end of its seven
When dangerous levels of CO are detected, the alarm will
sound and the red alarm light will flash as detailed below:
The amber fault light will flash twice every minute with two
beeps to indicate a fault with the sensor.
The amber fault light will flash three times every minute
with three beeps to indicate the unit is at the end of its life.
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 150ppm or above.
