Honeywell H450EN - Carbon Monoxide Alarm Manual

INTRODUCTION

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.

WHAT IS CARBON MONOXIDE

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. A dangerous quantity of Carbon Monoxide can occur if one or more of the following conditions exists:

1. An appliance is faulty or is badly maintained.
2. A flue is partially or totally blocked.
3. A room is not adequately ventilated.

IN WHICH ROOM TO PUT THE ALARM

Ideally, an alarm should be fitted in every room that contains a fuel-burning appliance. However, if there is more than one appliance and the number of units is limited, the following points should be taken into consideration when deciding on the best location:

• If there is an appliance in a room where people sleep, a unit should be placed in that room.
• A unit should be located in a room containing a flueless or open-flued appliance.
• If there is an appliance in a room which people use a lot, such as a sitting room, a unit should be placed in that room.
• In a bedsit, the unit should be placed as far away from the cooking appliance as possible but near to where the person sleeps.
• If the appliance is in a room not normally used, such as a boiler room, the unit should be placed just outside the room so that the alarm will be heard more easily.

INSTALLING THE ALARM

The unit can either be free-standing or wall mounted, using the fixings provided.

WALL MOUNTING INSTALLATION

Find a position to install the unit (see"where to put the alarm" and "where not to put the alarm").

Option 1 Special Mounting Pad with Fixing Pin (supplied)

Place the fixing pin through the mounting pad. Using a hammer, gently knock the fixing pin into the wall ensuring that the mounting pad is not hammered too firmly into the wall.

Option 2 Screw and wall plug (NOT supplied)

If the wall is too hard to use the fixing pin, use a No. 4 round head screw and Rawplug^TM.

Once activated and tested (see "using the alarm"), the unit can be hung on the protruding fixing pin using one of the 'keyholes' indicated on the back of the unit by the lines shown.

USING THE ALARM

To activate the unit, pull out the activation strip at the side of the unit. The green and red lights will flash briefly and the buzzer will sound a short chirp.

Press the test button and hold for up to 5 seconds and check that the red light flashes and the buzzer sounds.

The unit is now operating and is ready for use.

EFFECTS OF CARBON MONOXIDE POISONING

Carbon Monoxide binds to the haemoglobin in the blood and reduces the amount of oxygen being circulated in the body.

POSITIONING THE ALARM

1. Units located in the same room as a fuel-burning appliance
   • If the unit is located on the wall it should be located at a height greater than the height of any door or window but at least 150mm from the ceiling. If the unit is mounted on the ceiling it should be at least 300mm from any wall.
   • The unit should be at a distance of between 1m and 3m from the potential source.
   • If there is a partition in a room, the unit should be located on the same side of the partition as the potential source.
   • In rooms with sloped ceilings, the unit should be located at the high side of the room.
2. Units located in sleeping rooms and in rooms remote from a fuel burning appliance
   • Units should be located relatively close to the breathing area of the occupants.

WHERE NOT TO PUT THE ALARM

Do not place the unit in the following areas:

• Outside the building.
• In or below a cupboard.
• In a damp or highly humid area e.g. a bathroom.
• Directly above a sink or cooker.
• Next to a door or window or anywhere that would be affected draughts, eg, extractor fan or air vent.
• Where the air flow to the unit would be obstructed by curtains or furniture.
• Where dirt or dust could collect and block the sensor, and stop it working.
• In an area where the temperature could drop below -10˚C or rise to above 40˚C.
• Where it could be easily knocked, damaged, or where it could be inadvertently removed.
• Do not paint the unit or allow the CO gas inlets to become blocked by dirt, grease or other substances.

CAREFULLY READ AND UNDERSTAND THE CONTENTS OF THIS INSTRUCTION MANUAL BEFORE USING THE ALARM. RETAIN THE MANUAL IN A SAFE PLACE FOR FUTURE REFERENCE.
PAY PARTICULAR ATTENTION TO THE SAFETY WARNINGS. PASS THE MANUAL ONTO ANY SUBSEQUENT USERS OF THE ALARM.

THIS CARBON MONOXIDE ALARM MAY NOT PROTECT PEOPLE WHO ARE AT SPECIAL RISK FROM CARBON MONOXIDE EXPOSURE BY REASON OF AGE, PREGNANCY OR MEDICAL CONDITION. IF IN DOUBT, CONSULT YOUR MEDICAL PRACTITIONER.

This Carbon Monoxide Alarm is NOT:

• A substitute for either a smoke alarm or a combustible gas detector.
• To be seen as a substitute for the proper servicing of fuel-burning appliances or the sweeping of chimneys
• To be used on an intermittent basis, or as a portable detector for the spillage of combustion products from fuel-burning appliances or chimneys.

This Carbon Monoxide alarm is designed for indoor use only. Do not expose to rain or moisture. Do not knock or drop the unit. Do not open or tamper with the unit as this could cause malfunction.
