Fire Alarm Systems

Under British standards all commercial property must have a fully functioning fire alarm system maintained by a competent person or company.

Fire alarm systems come in many different forms. From a basic domestic mains powered systems to very complex digital addressable systems covering vast complexes. Fire & Audio Solutions have the ability to supply, install, replace, commission and maintain fire alarm systems for a wide variety of applications.

Fire alarm systems are generally categorised as conventional or addressable. Increasingly often, aspirating fire detection systems are integrated into fire alarm control systems, to meet fire detection standards in challenging environments. Fire & Audio Solutions have an in-depth knowledge of fire alarms, as one of our staple products we have the expertise to fulfil all of your fire alarm requirements.

 

Addressable Fire Alarm Systems

Addressable fire alarm systems are the desirable choice for all buildings and sites. Offering the same detection methods of conventional systems; automatic detection, manual call points, sounders and input/output relays. Addressable systems have a distinct advantage over conventional systems.

Addressable fire alarm systems can provide precise activation or fault identification down to individual device level. With the ability to store text locations, addressable systems have pinpoint accuracy when identifying the cause of an activation. A fire officer can make his way straight to the activation without wasting time searching the whole zone.

These systems also have a glaring advantage in the fact that they have programmable cause and effects. This offers in-depth programming to introduce delays, phased evacuation, the ability to switch between day/night mode and a vast array of other programming options.

Each fire alarm panel has its advantages and its restrictions. This is why we prefer to choose the best fire panel for every different application, rather than sticking with a manufacturer that cannot deliver the correct requirements.

Conventional Systems

Conventional systems are usually reserved for smaller buildings such as restaurants, shops and small schools. With the exception of very old systems, most conventional fire alarm systems operate using automatic sensors, manual call points, sounders/bells and input/output relays.

The major difference between conventional and addressable systems are the way in which they identify a fire location on the panel. Conventional fire alarm panels can only go as far identifying a specific zone as the cause of the activation.

Once the activated zone has been established a fire officer will investigate the area to locate the cause of the fire. Ususally an LED will be lit on the offending device to signal that device has activated. Although this is perfectly feasible in smaller buildings, in medium to large buildings and sites, conventional systems cannot provide a precise enough location to effectively trace the cause of the activation.

Aspirating Fire Detection

Also known as aspirating smoke detection (ASD), depending on the type of system. Aspiratng fire detectors are separate panels that are connected to the main fire alarm control panel. They are often used in more challenging locations or when early fire detection is important such as; server rooms, under floors, inaccessible roof spaces and refigerators.

Aspirating systems operate by taking samples of the air, drawing it back into the panel and analysing for signs of smoke (some can detect combustible particles). This allows aspirating fire detection systems to detect signs of a fire much quicker than ordinary smoke detectors. Early detection of a fire or potential fire is extremely important, faster detection saves lives.

Fire & Audio Solutions have years of experience maintaining aspirating fire detection equipment and understand the importance of these systems. If you have an aspirating fire/smoke detection system or require one, we can ensure yours is correctly installed and maintained to the highest standard.
