Choosing a fire alarm system

Selection

Fire alarms can range from a single smoke detector with a built-in sounder through to elaborate systems involving panels, manual call points and multiple detector heads. The main standard applicable to the selection of your fire alarm system is BS5839-1:2017 (part one system). It provides guidance applicable to fire alarms in non-domestic properties. For domestic properties the standard is BS5839-6:2019 .

What’s involved in a part one system?

There are three broad categories in BS5839-1 which cover systems which are activated manually only, i.e. via press, or break glass call points, and others which incorporate automatic detection.

Many BS5839-1 systems incorporate a control and indicating panel which will display the location of the device which has been triggered. The panel also monitors the correct function of the system. Depending on complexity, the panel might also contact an alarm receiving centre or activate fire safety equipment such as releasing fire doors to the closed position.

Do you need a non-domestic system?

Although your premises might be wholly used for business purposes this does not necessarily mean that you require a non-domestic alarm system. These are codes of practice and should be used as a guide. In some situations, it may be perfectly acceptable to install a system in a small low risk premises that meets BS5839-6 instead. These systems are intended for domestic premises and the majority comprise one or more smoke alarms without any control and indicating panel.

Which is the smart choice?

One of the main benefits of a non-domestic system is that if an alarm is triggered, staff can quickly look at the panel to find out the source. With recent advancements in technology, however, you can still achieve this with domestic type equipment, in the form of smart fire detectors (see The next step ). Smart detectors also have the advantage of easy interconnection with other similar detectors in your property giving you a virtual interlinked system. They are quite often dual purpose, e.g. they detect smoke, carbon monoxide or heat and can be controlled from your phone.

Tip 1. Using smart detectors effectively gives you a fire control panel in the palm of your hand. It’s certainly a consideration for lower risk premises and although each detector might cost three times the price of a standard one, you’ll save on installation costs if you purchase those with a ten-year sealed battery.

Tip 2. Smart detectors have a self-test function which will automatically test itself as often as you wish and send you a report to your phone. This saves time and money on routine testing and servicing. The system also alerts you if there is a problem with any of the devices or interconnections.

Tip 3 . A fire risk assessment should be carried out by a competent assessor before deciding what type of system you need. Also check against any past conditions set by the local authority, insurer or local Fire and Rescue Service.
