Honeywell - Model H450EN -Carbon Monoxide Alarm
Carbon Monoxide (CO) is a highly poisonous gas which is released when fuels are burnt. It is invisible, has no smell and is therefore very difficult to detect with the human senses. The first warning symptoms that CO is present in the air are usually headaches and nausea. Under normal operating conditions, in a room where fuel-burning appliances are well maintained and correctly ventilated, the amount of Carbon Monoxide released into the room by the appliances is not dangerous.
Thank you for purchasing this alarm which is designed to detect the presence of Carbon Monoxide. This manual contains information on the installation and operation of the Carbon Monoxide alarm.The status light flashes green at approximately 1 minute intervals to indicate that the unit is operating correctly. This will change to a yellow flash synchronised with chirp if a fault arises. The red alarm light will flash continuously and the buzzer will sound if Carbon Monoxide is present.The unit is suitable for use in areas where cooking and heating appliances burn fuels such as wood, charcoal, coal, coke, oil, petrol, gas, etc
