Product Description
The Ei208DW 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
accuracy.
The LCD displays CO level, status messages and icons.
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
and sounder).
The alarm has an ‘End of life’ indicator which will notify the
user when the alarm needs replacing at the end of its seven
year life.
Operation
 When dangerous levels of CO are detected, the LCD will
display the CO concentration, the alarm will sound and the
red alarm light will flash as detailed below:
 When lower levels of CO are detected, the alarm will display
a ‘VENTILATE’ message. When higher levels are detected, the
alarm will display an ‘EVACUATE’ message.
 If the alarm is reaching the end of life or a sensor fault is
detected the alarm will display a ‘REPLACE UNIT’ message
and the amber fault light will flash three times every minute
with three beeps.
 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.

Technical Specification
1. The CO Alarm carries the BSI Kitemark to indicate type testing to BS EN 50291-1:2010. It is CE marked to indicate conformance to
BS EN 60335-1:1994, BS EN 50270:1999 Safety and Electromagnetic Compatibility Directives.
2. New generation electrochemical cell type Carbon Monoxide sensor checks CO concentration every 4 seconds. Each unit is calibrated and
tested in CO gas in order to ensure accuracy.
3. Battery powered. Sealed in Lithium battery that will power the unit for it’s entire life (7 years). The LCD will display a Low Battery
indicator and the amber fault light will flash twice every minute with two beeps to indicate that the unit needs replacing.
4. Start up sequence - the red, amber and green LEDs will flash once. Rapid warm up time - once this very short sequence has elapsed, the
alarm is in full operation.
5. CO level indicators as follows. The LCD display will also show the actual CO level in parts per million (PPM):
6. Fault indicator - the LCD will display a ‘REPLACE UNIT’ message and the amber fault light will flash twice every 50 seconds if a fault is
detected.
7. End of Life Indicator - the LCD will display a ‘REPLACE UNIT’ message and the amber fault light will flash three times every minute with
three simultaneous beeps if the unit has reached its end of life.
8. Manual Test/Hush button - press and hold the Test/Hush button to test circuitry, sensor and sounder. LEDs will flash as below:
Normal mode - Green LED flash with normal alarm sound along with a tick on the LCD display
Fault condition - Amber LED flash and LCD will display ‘REPLACE UNIT’. Alarm will not sound
End of life - Amber LED flash with beep and LCD will display ‘REPLACE UNIT’
10. Pressing and releasing the Test/Hush button when the unit is sensing CO will silence the alarm for 4 minutes. It will only silence once
until the gas clears. At CO levels of 150ppm and above the unit cannot be silenced due to the increased danger.
11. Memory feature which records the last CO level sensed. If the unit has been in alarm and then ceased, the red LED will continue to flash
for a 24 hour period to indicate the level of CO sensed. Pressing the test button will also show the last CO level sensed via the LCD
display and by the rate of flash of the red LED. As follows:
12. Built in sounder to give a minimum output of 85dB(A) at 3 metres. Modulated sound output - 3 rapid pulses followed by a 1½ second
pause, repeated until reset. This easily differentiates it from a typical smoke alarm.
13. Automatic reset of alarm test function and after an alarm state when CO gas clears.
14. Supplied with integral mounting base and fixing screws. The mounting base has multiple fixing holes and the alarm is suitable for
ceiling or wall mounting.
15. Operating temperature range: -10°C to +40°C. 15% to 95% relative humidity (non-condensing).
16. Dimensions: 120mm x 105mm x 45mm. Weight: 180g.
17. 5 year guarantee.
18. Manufactured in Ireland.
