Fire Alarm Installation Keighley

There are numerous choices of format with fire alarms, they all function on the same idea – A sensor detects, the main panel sees the difference and then tells people of the fact that a fire detection.

The sensing device can be a humble manual switch which signifies that the fire was detected by a person who then manually triggered the detection system. More high-tech detectors identify either carbon monoxide, smoke, flames or heat. In general, flame and heat units are the most slow as the fire may be well established by the time they trigger.
Alerting others is accomplished in two ways: Strobes and Sirens throughout a premises and remote notification such as getting a fire and emergency response by automatically exchanging data with a alarm receiving centre.
The fire alarm system format can differ based on several factors: cost, design considerations , building size, business operations, fire-risk-assessment outcomes and insurance company requirements. The main four formats are: Conventional and Addressable.

Conventional Fire Alarm Installation Keighley

Conventional fire alarms have units cabled together in clusters in order to give a general area of where the fire has occurred e.g. offices, warehouse etc. Each group of units is known as a zone. A zone diagram next to the control panel then shows where the blaze has been detected. It is a simple method but perfectly effective for many smaller and medium sized organisations.

Addressable Fire Alarm Installation Keighley

Addressable systems also cable detecors together but importantly they can show exactly which detector has alarmed. Countless more detectors can be put on a loop. The detectors function like conventional ones but are able indicate their address by adjusting DIL switches on the sensor. They are often employed in bigger buildings.

Analogue Addressable Fire Alarm Installation Keighley

Analogue Addressable systems are known as technical fire alarm systems. The detectors in addressable and conventional systems are quite basic while in an analogue addressable detection system the detectors have some inbuilt intelligence and can recognise whether they are in alarm, in open circuit or want cleaning. Also, sirens and other modules can be placed on the same loop making systems very flexible. These are suitable for big, complicated buildings and organisations.

Wireless Fire Alarm Installation Keighley

Wireless fire systems, as they sound, are cable free. The devices are more costly but there are cost cuts on installation expenditure. They can be a 100% analogue addressable or can be just supplementary to a conventional one where running cables would be time consuming.
