Aico 3000 Multi-Sensor Heat and CO Alarm is built with the same high quality, reliable and proven technology as in our other Heat and CO alarms but combined in one alarm and with advanced intelligent technology. There are a number of fire and carbon monoxide (CO) risks within a typical home. For example, cookers in kitchens pose a fire risk, being responsible for 50% of accidental fires in dwellings. In addition, many of these areas also contain gas fuelled appliances such as boilers which present an additional risk from CO – a poisonous gas that you can’t see, smell or taste. t’s vital to protect against both risks. Previously the answer to this would have been to fit two alarms, a heat alarm and a CO alarm, however this protection can now easily be achieved by using the new Ei3028 multi-sensor which detects both fire and carbon monoxide in a single alarm.
