Fire Alarm Installation Leeds
There are varied options of format with fire systems, they all function on the same simple idea – A sensor activates, the controls sees the change and then notifies others of the reality that a fire has occurred.
The sensor can be a humble manual switch which denotes that the fire was detected by a person who then manually triggered the fire alarm. More complex units identify either flames, smoke, heat or CO. Generally speaking, flame and heat detectors are the most sluggish as the fire would probably be well alight by the time they go off.
Informing others is done in two ways: Strobes and sounders all through a building and remote alerts such as getting a fire service response by automatically connecting with a monitoring centre.
The fire system format can differ based on numerous factors: budget available, design considerations , building size, business processes, fire-risk-assessment results and insurer’s needs. The four formats are: Conventional, Addressable, Analogue Addressable and Wireless.
Conventional Fire Alarm Installation Leeds
Conventional fire alarms have detectors wired together in groups to give a simple geographical idea of where the fire is e.g. third floor, fourth floor etc. Each set of devices is described as a zone. A zone drawing by the control unit then shows where the alert has been picked up. It is a basic system but adequate for many small / medium sized companies.
Addressable Fire Alarm Installation Leeds
Addressable systems also cable detecors together but critically they can signal precisely which unit has activated. Lots more units can be cabled on a loop. The units operate like conventional components but can indicate their address by throwing in-line switches on the base. These fire systems are frequently used in big premises.
Analogue Addressable Fire Alarm Installation Leeds
Analogue Addressable systems are known as intelligent detection systems. The units in addressable and conventional systems are fairly dumb while in an analogue addressable operation the units have some built-in processing and can work out whether they have activated, shorted out or need cleaning. Likewise, sounders and other components can be put on on the same loop making design very adaptable. These Systems are suitable for bigger, complicated premises and businesses.
Wireless Fire Alarm Installation Leeds
Radio detection systems, as they sound, are wire free. The units are costly but there are savings on labour. These systems can be a 100% analogue addressable or simply an addition to a conventional system where running wires would turn out to be awkward.
