Buying a Smoke Alarm


Buying a Smoke Alarm: Which Is Best for You?

Initially, you would be forgiven for assuming that all smoke alarms are the same, but the truth is that although they operate in similar ways, there are differences in how the smoke alarm will be activated.

To be confident that you’re purchasing the right smoke alarm, it’s useful to know how about the different smoke alarms available, as well as how they work.

Ionisation Smoke Alarms

An ionisation smoke alarms is often the cheapest smoke alarm available, but it’s important not to focus on the price alone when purchasing a smoke alarm solution, as there many other factors to consider.This includes considering what smoke alarm suits each room best.

Ionisation smoke alarms work by ionising the air between two electrodes, which creates a small current activating the alarm.

These types of alarms are generally fine for landings and lofts but can be too sensitive for kitchen areas.

Optical Smoke Alarms

Optical smoke alarms are also known as photoelectric alarms work via the use of sensors. Should smoke be detected, the infrared light will be scattered onto a photodiode light receptor.

This type of smoke alarm isn’t as delicate as ionisation smoke alarms, so can be used in the kitchen.

However, they’re not the best for dusty or steamy environments, so rooms such as the bathroom will require a different approach.

Heat Detectors alarms

As the name suggests, a heat alarm is activated by a rise in temperature as opposed to smoke being present, which is done using a thermistor.

These types of smoke alarm are ideal for kitchens and garages as they aren’t sensitive to smoke. However, they shouldn’t be used throughout the property as they aren’t as quick to respond as other smoke alarms.

In England, the minimum guide for alarm positioning to meet building regulations is as below:

position optical or multi-sensor mains powered alarms with an integral backup power supply within the escape routes of the property (i.e. hallways and landings)
Have at least one smoke alarm on every floor
Install a heat alarm in any kitchen areas where the kitchen is not separated from the circulation space or stairway by a door
All alarms must be interlinked
