Fire Alarm Systems

Fire Alarm Systems

When it comes to fire alarm systems we can meet all your needs.

We offer a free consultation to discuss the best fire alarm system for your company and can handle everything from the design stage through to installation, commissioning and hand-over.

Often a company calls us after they have had a fire risk assessment done or their insurance company says they need an alarm fitting.

We have many years of experience in fire alarm systems. So let us take away the strain by booking your consultation now:

We design, install and commission all our systems to BS 5839 PART 1 2017

Fire Alarm Design

It is crucial that your fire alarm system is designed to meet the specific needs of your company. No two designs should ever be the same because badly sited detectors – or having the wrong type installed – can lead to false alarms.

All our design staff are trained by the BFPSA/FIA.

There are many different types of fire alarm systems but the most common include:

  • Non-addressable systems - These are best suited to smaller buildings and usually consist of 10 to 25 detection devices.
  • Addressable systems - These are usually found in larger buildings and are capable of complex programming to provide a wide range of applications. For example, ventilation systems, fire breaks and the closing of fire doors on corridors.
  • Radio fire systems - We will usually suggest this type of system when wiring isn’t allowed, such as in listed buildings like churches and stately homes.

Fire Alarm Installation

We fit all our fire alarm systems to meet British standards BS5839. All our equipment is of the highest quality and is designed to minimise the risk of false alarms.

Your company will be provided with a drawing of the system layout which will be needed if you wish to add to the system in the future or to detect problems.

Category Types:

  • Category ‘M’ systems are manual. These include manual call points and therefore no automatic detection
  • Category L systems are to protect life.
  • L1 system - manual detection at defined points, and automated detection throughout all areas
  • L2 system - Manual detection at defined points and automatic detection on all escape routes, rooms which open on to escape routes and high risk / hazardous areas
  • L3 system - manual detection points and automated detection on all escape routes and room which open on to escape routes
  • L4 system - manual detection points and automated detection on all escape routes
  • L5 system - Manual detection points and automatic detection in areas designed to satisfy specific fire safety objectives
  • Category P systems are for the protection of property.
  • P1 - Automatic detection installed throughout the building
  • P2 - Automatic fire deception installed in defined areas of the building.

Fire Alarm Commission and Hand-over

Before we hand-over the completed fire alarm system, checks will be carried out to ensure every aspect of the work meets the specifications in the plans exactly. The full system will be tested to make sure everything works, as it should.
You will then receive all the necessary documents, certificates, operating manual and logbook.
