A fire alarm will work only as well because it’s fitted, and will just work as long as it’s maintained.

“Nationally 80 per cent of homes now own smoke alarms but in 12 percent of house fires attended by fire and rescue agencies the smoke alarm failed to alert system, mainly because of flat or missing batteries” – origin: UK’Firekills’ effort

Both the UK Fire Service and US Fire administration recommends that alarms are fitted to every level of the house. Smoke alarms should be fitted in bedrooms when there is a TV or other large electrical appliance. In case you have only 1 smoke alarm and two floors, it needs to be set up where it could be discovered when asleep – in the ceiling on top of the staircase leading to the bedrooms, is usual. Even though ionisation and optical alarms are both powerful, optical alarms may be preferred in this particular situation since they’re especially good at discovering slow-burning, smouldering fires.

Smoke alarms usually mount on foundations which are simply screwed into the ceiling. They ought to be fitted as near the middle of the room as possible, but at least 30 centimetres (12 inches) away from any wall or light fitting. You always need to ensure your alarm is fitted at a location where it could be heard through your home – particularly when you are asleep. If your house is on one level, you should fit the alarm in the hallway between the sleeping and living areas.

It’s strongly Suggested by all manufacturers and fire prevention bodies that the following points should always be followed when installing and maintaining your smoke alarm:

1. The manufacturers’ instructions should be followed in Any Way times

2. Mains powered alarms must always be installed by a qualified, registered electrician

3. Smoke alarm batteries have been tested once weekly and changed once annually.

It’s probably quite evident that there are a range of fire alarms available, and at vastly changing costs, so it could be very difficult to understand the differences between Optical, Ionisation and Heat alarms. This guide is aimed at taking some of that confusion away.

So what is the distinction between the models?

As stated above there are 3 kinds of alarmclock, each with its own applications.

Optical Alarm: this kind of smoke alarm usually utilizes an infrared beam between two points, the alarm being triggered should the beam be bothered. In much the exact same way as a criminal might trip an alarm when breaking into a bank vault or museum at the movies, when the beam is broken, then the alarm will go off. It finds larger smoke particles best.

Ionisation Alarm: All these alarms use 2 small plates (one charged positively, one negatively) and an alpha particle source to create a constant current running across the gap between the plates. After the charge falls, the alarm clock goes off. These alerts will be best at detecting smaller smoke particles.

Heat Alarms: A heat alarm will trigger if the room temperature reaches a specific level. They do not detect smoke, and are not to be utilized as a substitute
