Aico Ei208W Carbon Monoxide Alarm CO

Aico Ei208w Carbon Monoxide Alarm With Lithium Battery

A sealed-in Lithium battery powers the Ei208W alarm ensuring a high performance, and proven electrochemical sensor to sensor CO presence.  

During assembly each sensor is indivudually calibrated and tested to ensure accuracy.
The unit is easily secured to ceiling or wall by way of a twist-on mounting base with multiple fixing points.
The last CO level sensed is recorded using the memory feature making it possible to check if CO has been present during any absences from the property.
The unit has a Test/Hush button which is easy to use and allows all aspects of the unit to be constantly checked.
An end or life indicator notifies the user when the alarm has reached the end of its six year life.

Operation

An alarm will sound and a red light will flash whenever dangerous levels of CO are detected.
When the unit needs replacing an amber light will flash twice every fifty seconds.
If a fault in the sensor is detedted the alarm will beep and the amber fault light will flash twice every 50 seconds.
Alarms can be silenced by exerting a brief 'push' on the Test/Hush button or the unit can be programmed to run a self test if the Test/Hush button is pressed and held.  Please note that if a CO level of 150ppm or above is detected the alarm cannot be silenced.

Technical Specification

The CO alarm carries the BSI Kitemark to indicate type testing to BS EN 50291:2001. 
It is CE marked to indicate conformance to BS EN 60335-1:1994, BS EN 50270:1999 Safety and Electromagnetic Compatiility Directives. 
New generation electrochemical cell type Carbon Monoxide sensor checks CO concentration every four seconds. 
Each unit is calibrated and tested in CO gas in order to ensure accuracy.
Battery powered by a sealed-in Lithium battery that will power the unit for its entire 6 year life.
The amber fault light will flash twice every fifty seconds to indicate the unit needs replacing.
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 fully operational. 

Low and high CO level indicators are as follows:

Fault indicator - amber LED flashes twice and the alarm beeps every 60 seconds if a fault is detected.

Manual Test/Hush button - press and hold the button to test circuitry, sensor and sounder.  LEDs will flash as below:

Pressing and releasing the Test/Hush button when the unit is sensing CO will silence the alarm for four minutes.  It will only silence once until the gas has cleared. 

At CO levels of 150ppm anbd above the unit cannot be silenced due to the increased danger.

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 show the last CO level sensed, via the rate of flash of the red LED as detailed below.

Built in sounder to give a minimum output of 85dB(A) at 3 metres. 
Modulated sound output - 3 rapid pulses followed by a 1.5 second pause, repeated until reset.  This easily differentiates it from a typical smoke alarm.
Automatic reset of alarm test function and after an alarm state when CO gas clears.
Supplied with integral moutning base and fixing screws.  The mounting base has multiple fixing holes and the alarm is suitable for ceiling or wall mounting
Operating temperature range:   -10 degC to + 40degC.  15-95 per cent relative humidity (non-condensing).
