Fire alarm installation and testing

We all know fire can be very dangerous to lives and property that's why fire detection shouldn't be taken lightly.

If you are unfortunate to have a fire you need to know about it as soon as possible whether it's at home or in the work place. Fire Detection & Alarm Systems protect both life and property. They alert workers and external services to unexpected and dangerous events, and allow appropriate and timely action to be taken.


WELT supply, install and maintain a wide range of fire detection and fire alarm systems to meet all fire safety applications. Whether a small convention system or a networked addressable system, we are able to guide you through the complete process of design, installation and commissioning.


Tackling a small fire with a maintained fire extinguisher may make the difference between a small incident and a full scale disaster.  Extinguishers are essential for the safety of your staff and visitors.  They can also help the preservation of property and ensure business continuity by not letting a small fire develop in to a major one.  Many Insurers now insist on extinguishers being present (and maintained by a BAFE Approved Company) to mitigate the risks that fire represents.


Conventional Fire Systems

WELT can connect conventional fire alarm systems with other fire alarm panels on site or install communicators, which are monitored by a Alarm Receiving Centre (ARC) ensuring a rapid response from the emergency services.

WELT supply, install and service all types of conventional type fire alarm systems. These can range from 1-84 zones and are ideal for small applications such as apartment buildings, shops and offices.

Conventional fire alarm systems are a cost effective way to ensure you have a means of detecting & warning of fire.

Numerous detectors can be installed into zones, when a detector is triggered the fire alarm control panel can indicate which zone has been triggered, giving the client or the fire brigade an indication of the area of activation.

Addressable Fire Systems


We can supply, install or service all types of addressable type fire alarm system. These systems are a more intelligent type of fire alarm system with the following key advantages over conventional control panels.

•       Identifies exact location of activated device

• Loop sounders

• Panel networking

• Printers

• Graphic interface

• Interface connections to 3rd party devices

If a detector is triggered it gives a text read out of exactly where this unit is. The main advantages of this system are for large buildings where a detector on a conventional zone may take some time to find.


As well as giving an exact point of the detection, various other options are available including intelligent control of other equipment, Sounders on the same circuit, cause & effect programming and phased evacuation.

Why do I need a Fire alarm service contract?

This is a requirement of BS5839, the Fire Risk Assessment of your Premises and your legal requirements to your insurers.


Fire Alarms

We offer a comprehensive range of both conventional and analogue fire alarm systems together with their accessories, including a variety of detectors, bells, sounders, strobes and door retainers.

Our services include: brand new installations, servicing and maintaining of existing installations and periodic testing and inspections.

We can cater for both environments, Domestic and Commercial.

All works carried out comply with all current regulations BS5839 and certified on completion.

The full design criteria for fire alarm and detection system is laid down in BS5839: Part 1: 2002 and provides specific guidance on all aspects of fire alarm and detection from design, supply, installation, commissioning, test and routine maintenance.


The design of a system varies considerably depending on the type of premises to be protected and the level of protection required. As with any life safety (or business critical system) it is important that the finished item is efficient and reliable. We strongly recommend consultation with your local Fire Prevention Officer who will be able to provide advice on their preferred system type and any local or government legislation that may have to be complied with.

Fire alarm systems fall into two main categories, manual fire alarm systems and automatic fire detection systems.

A manual alarm system which consists of break glass units and alarm sounders connected to a control panel, can only be operated and the alarm raised, if activated by a person discovering a fire incident.


An automatic system comprises of smoke and heat detectors, in addition to break glass units and alarm sounders connected to a control panel. Automatic systems have the ability to raise the alarm regardless of the presence of occupants, which provides an early warning of a fire incident.

What sort of organisation or business needs a fire alarm service contract?

Every company, individual and/or organisation, no one is exempt, where a Fire Alarm System is fitted as a requirement of planning laws and thus must be maintained.


Selection of Detection Equipment Types

When choosing the type of detector to be used in a particular area it is important to remember that the detector has to discriminate between fire and the normal environment existing within the building, i.e. smoking in hotel bedrooms, fumes from forklift trucks in warehouses, steam from bathrooms, kitchens etc.There are :

Zone Details 

An important consideration when designing fire alarms is that of individual zones.

• A single zone should not exceed 2,000m² in floor space.

• Where addressable systems are in place, two faults should not remove protection from an area greater than 10,000m².

• A building (no matter how many floors it has) may be viewed as a single zone if the floor space is less than 300m².

• Where the floor space exceeds 300m² then all zones should be restricted to a single floor level.

• Stairwells, lift shafts or other vertical shafts (non stop risers) within a single fire compartment should be considered as one or more separate zones.

• The maximum distance traveled within a zone to locate the fire should not exceed 60m.

• If the zone covers more than one fire compartment, then the zone boundaries should follow compartment boundaries.


Emergency lighting is the perfect solution when faced with a power supply failure and can also act as an additional lighting source. In addition, under current fire safety legislation and British Standards, it is a legal requirement to provide illuminate the escape routes from a premises until a place of safety is reached.

In an emergency situation, sudden darkness can pose serious threats to occupants of a property and can make the process of evacuation a much more complex and dangerous task.

Emergency lights are self contained units that are wired into the mains, but have the benefit of battery backup which enables them to remain illuminated should the mains power fail. The batteries can either be carried within the body of the individual light or accessed by lights via an independent wired circuit. The batteries are kept charged via the mains.

What is Emergency Lighting?

Why do I need such lights? 

Because in the event of a power fail you must ensure your building is evacuated safely and quickly and the escape routes and emergency exits need to be illuminated to achieve this.

<> Control combustibles and inflammables materials and safe storage within the work place.

<> Check Wiring and Electrical Appliances regularly for safety, correct fuses used etc.

<> Clear rubbish and combustible materials from site.

<> Allow smoking in designated areas only.

<> Fire Exits are there sufficient and do they lead to places of safety. Are they unlocked?

<> Escape Routes must be kept clear, and free of obstructions.

<> Building must be properly maintained so that stairways, passageways are safe.

<> Signage indicating Fire Exits and Escape Routes.

<> Emergency Lighting for escape routes and exits, install and check regularly.

<> Evacuation plans to be made and drills rehearsed regularly.

<> Fire Wardens to be trained.

<> Insurers to be consulted for their advice and requirements.

<> Do you need an Automatic Fire Detection and Alarms system.

<> It must be maintained and tested regularly.

<> When making changes to the building, ensure that the Fire Alarm or escape routes or exits are not compromised.

<> Is the Fire Alarm connected to an Alarm Receiving Centre for calling out the Brigade automatically (recommended).

<> Are there sufficient Fire Extinguishers and Blankets on site, are they working and maintained regularly.

<> Are they ways of compartmentalising buildings to stop the spread of Fire throughout the building, think Fire Doors etc.

<> Have you prepared an emergency plan and communicated it to all staff.

<> Review all such matters and keep your risk assessment up to date.
