Alarms & Emergency Lighting

Around 80% of single site businesses never recover from a serious fire. Early detection not only provides early warning of a fire to employees but can also reduce the resultant fire spread and collateral damage and loss to the business.

Fire alarms and emergency lighting systems are designed to (i) give advance warning of a fire and (ii) ensure anyone in the building escapes as quickly and safely as possible.

We can provide your Fire alarm and Emergency Lighting installation requirements. We offer a wide range of solutions to suit different building types and applications.

We also offer a servicing and testing service for your fire alarm system.

All work is undertaken to British Standards BS5839 (Fire Alarms) and BS5266 (Emergency Lighting).

Types of Fire Alarm Systems

The most common types of alarms that businesses use are conventional and addressable alarm systems. Both types of alarm link devices (such as call points and smoke detectors) to a main control panel.

Which is the cheaper option for you?  Conventional alarm panels cost a lot less to buy but are more expensive to install. This is because each device that is being connected needs its own wire. With addressable systems, one wire loop will connect several devices. This means conventional systems require more wire and more hours during the installation phase.

Overall  Functionally, the addressable fire alarm unit is superior, which can help prevent costly activities and save time when detecting a fire. It’s also cheaper and easier to install. But in terms of buying price, a conventional system is cheaper, and will meet the functional needs of small premises where a sophisticated system is not necessary.

Types of Fire Alarm Detectors

Ionization smoke alarms create an electric current between two metal plates, which sound an alarm when disrupted by smoke entering the chamber. They can quickly detect the small amounts of smoke produced by fast flaming fires but can be prone to nuisance tripping.

Photoelectric smoke detectors (sometimes known as Optical) contain a light source in a light-sensitive electric sensor. Photoelectric smoke detectors typically respond faster to a fire in its early stage i.e. before the source of the fire bursts into flames. They are more sensitive to the large combustion particles that emanate during slow, smouldering fires, which usually occur at night when people are asleep. They are particularly good in areas where you can otherwise expect false alarm

Overall  Ionization type alarms provided somewhat better response to flaming fires than photoelectric alarms, and photoelectric alarms provide considerably faster response to smouldering fires than ionization type alarms.

Ionisation smoke detectors are the cheaper of the options, In the right location they are efficient, reliable but may be prone to giving false alarms if installed in unsuitable areas e.g. food preparation areas, dusty workshops or garages, insect activity etc.

Photoelectric smoke detectors although more expensive, their detection method provides a more reliable response rate and accuracy reducing false alarms.
