Fire Alarm & Detection Installations
The first step to suppressing a fire is to detect it before it becomes too big to handle. Fire alarms come in many different varieties that vary in both price and effectiveness.
What Different Fire Alarms are there?
- Heat Alarms – Heat alarms trigger when they detect a substantial increase in temperature and are also sensitive to the presence of smoke. They are a great type of alarm to be installed in the kitchen because their coverage only spans a small area when compared to some of the other types of alarm on the market. This means you might want to get a couple of alarms rather than just one if you are thinking of enquiring into heat alarm installation.
- Ionisation Alarms – Ionisation Alarms are cheap and aim to detect rapidly spreading fires (such as burning paper or burning wood). This is because they are sensitive to smaller particles than other types of alarms. Ionisation Alarms have the tendency to be over sensitive if they are placed in the kitchen as smaller streams of smoke that may not be as a result of a fire could potentially trigger them.
- Optical Alarms – Optical alarms are typically the most expensive alarms – but you get what you pay for. They detect larger smoke particles produced by fires that burn slower (such as fires that smoulder from burnt wiring). Since they are less sensitive to smaller streams of smoke but are more efficient at detecting smoke caused by smouldering fires they should be placed just outside the kitchen area.
- Combined Alarms – These alarms can detect smoke and carbon monoxide, an invisible and deadly killer. The benefit to having a two-in-one detection system is that aesthetically, it looks more pleasant and takes up less room; also it is easier to maintain as you just have to ensure the one device is working up to speed.
All the above alarms look similar, and are powered by either battery or electricity from the mains. More expensive alarms are powered from the mains, with a battery back up to ensure that the alarm will be operational even if the mains power went out in the event of a power cut. These should be installed in commercial settings where it is essential to maintain the highest standard of safety for everyone working at the premises.
Newer alarms have inbuilt “ease of life” features, such as sleep modes that silence the low battery beeps during night hours, this is done to make sure you get a peaceful night’s sleep.
As well as this, “hush” buttons are present on newer devices to nullify false alarms (as we all know it can be a pain to carry out the cooking to background noise of immense non-stop bleeping).
Recent alarms also come with an “escape light”. These lights trigger when the alarm does, which can illuminate an escape route and potentially save your life if you are caught in a house fire in the middle of the night.
