Types of Smoke Alarm

Six different grades of fire detection systems are being defined. Generally speaking, the greater the fire risk the more sophisticated the system should be. Briefly, these 6 grades are:

Grade A - A full system with control and indicating equipment must be installed to BS 5839: Part 1

If you have a large home or need a smoke alarm fitted in a commercial building then a linked or interconnecting alarm is recommended. These are smoke alarms that trigger other alarms to go off in the event of a fire. So when one alarm detects smoke all of the alarms in the property will go off alerting people all over the building that may not have heard the original alarm.

Grade B - Detectors and sounders using simpler specified equipment
Grade C - Detectors and sounders or alarms with central control
Grade D - Mains powered alarms with an integral stand-by power supply

Mains powered alarms are the most reliable domestic and commercial smoke alarms as they run off your home or buildings main incoming power supply. Once the Smoke alarm is correctly installed you will not have to test the battery regularly, although they do have a battery back up in the event that you have a power cut. These smoke alarms need to be installed by a qualified electrician.

Grade E - Mains powered alarms with no stand-by power supply
Grade F - Battery powered alarms

The most popular alarm used in the home is the standard battery alarm which is an, ionisation battery alarm you can also get an optical battery alarm both standard alarms run using a 9-volt battery.
There are three different categories of life protection system:-

  • LD1 - Alarms in all circulation spaces that form part of escape routes and all areas where a fire might start, but not bathrooms, shower rooms or toilets
  • LD2 - Alarms in all circulation spaces that form part of escape routes and rooms or areas that present a high fire risk
  • LD3 - Alarms in circulation spaces that form part of escape routes

BS 5839: Part 6: 2004 emphasises that no one type of alarm is most suitable for all applications.
Consideration must be given to the most suitable type of detection - optical, ionisation or heat.  
Specialist electrical contractor Essex based delta T Renewables can carry out all of these works to the very highest standard.

Ionisation alarms

Ionisation alarms use ionisation type sensors that are sensitive especially to smoke which is almost invisible to the human eye. This type of smoke is produced by fast flaming fires. This feature causes them to be more liable to false alarms due to cooking fumes should they be sited close to the kitchen or in an adjacent room. On the other hand ionisation alarms are less vulnerable to false alarms caused by dense smoke, cigarette smoke for instance, excessive dust and insect ingress. The British Standard BS 5839: Part 6: 2004 recommends that the ionisation alarms should not be used in landings or hallways - places where there is a high risk of false alarms that are caused by cooking fumes.

Heat alarms

Heat Alarms are not as likely to cause false alarm problems since they are not responsive to any type of smoke or fumes; they are sensitive to heat only. Because of the possibility of having a slower response than the smoke alarms, it is recommended that the heat alarms would be used in a fire alarm system that include smoke alarms also, and all the alarms must be interconnected. In line with the British Standard BS 5839: Part 6: 2004 recommends that heat alarms should be used in kitchens; it continues to suggest that they may also be used in the main living room but they should not be installed in the circulation spaces or areas where fast response to fire is required

Optical Alarms

Optical Alarms are more immune to the invisible smoke produced by cooking fumes. The optical sensors are more responsive to smouldering fires producing large particle smoke, typical of fires that involve furniture and bedding. This characteristic makes them ideal for being sited in hallways close to the kitchen, where false alarms from ionisation alarms may be a particular problem. The BS 5839: Part 6:200 recommends the use of optical alarms in circulation spaces of a dwelling, such as hallways, landings, etc.

Optical alarms are prone to false alarm if they are exposed to steam, so they should not be located too close to poorly ventilated bathrooms or shower rooms
