The Electrochemical Cell – Provides effective and responsive, long term detection
- Carbon Monoxide enters the sensor through a gas diffusion hole. A Graphite filter prevents any external contaminants from entering. A Platinum sensing electrode catalyses the oxidation of the CO.
- Combining with the water present in the electrolyte, this reaction causes the voltage to rise. Consequently, a small current flows between the two electrodes.
- This output is directly proportional to the amount of CO gas present. The microchip in the unit activates the horn/LED/display to give a warning applicable to the CO level sensed.
Locating and Positioning CO Alarms
Where should CO Alarms be located?
- Install an Aico CO Alarm in all rooms where there is a fuel burning appliance;
- If there is more than one appliance, but only one CO Alarm is to be installed, the following priority list is recommended:
- Rooms containing a flue-less or open-flued appliance;
- Rooms where occupants spend most time;
- Rooms in which the appliance is most used;
- If the dwelling is a bedsit the CO alarm should be positioned away from the appliance, but close to the sleeping area.
CO Alarms should not be located:
- In an enclosed space e.g a cupboard;
- Where it can be obstructed;
- Directly above a sink;
- Next to a door or window;
- Next to an extractor fan or vent;
- Where dirt & dust may block the sensor;
- In a damp or humid location;
- In the immediate vicinity of a cooking appliance.
When only one CO Alarm is to be fitted, audibility of the sounder may be a problem in other areas of the property.
Where should CO Alarms be positioned?
The preferred position is in rooms containing a fuel burning appliance, more exactly:
- 1-3m horizontally from the appliance;
- At least 300mm from any wall and obstructions (e.g. light fitting);
Wall Mounting Option
- 1-3m horizontally from appliance;
- 150mm vertically down from ceiling;
- Above the height of any doors or windows;
