Fire Alarm & Assessments for Business

As a business owner or commissioner of a fire safety system, you have a legal responsibility to carry out a fire risk assessment under the mandatory Fire Regulatory Reform Order (RRO)

This doesn’t have to be as daunting as it sound. Contact us for a link to a simple risk assessment guide which is appropriate for your business. This guide will allow you to carry out a risk assessment for your building and business activities, and assess the potential fire risks. (Guides provided by Hereford and Worcester Fire Brigade via their website)

It can be quite confusing trying to decide what fire alarm system you need for your business, so we are here to help.

What kind of alarms are there?

A straight forward system typically includes the following:

  • A control and Indicator Panel
  • Manual Call Points (break glass call points) next to exits, with at least one call point on each floor.
  • Electronic Sirens or Bells
  • Automatic fire detection in the form of Smoke and/or Heat Detectors

At P & R Alarms we remove all the hassle by offering a full system design and installation service based on your risk assessment findings.

All of our equipment and systems comply with British Standards and the mandatory requirements of the RRO, which common sense dictates all businesses must have a fire alarm.

How many detectors do I need?

The amount of detectors needed is dependent on the size and layout of your property along with the number of floors it has.

BS5939:2002 provides details on the numbers and locations of detectors you will need in your business.

You should at minimum have detectors on all escape routes from your premises (Category L4). Earlier warning can be achieved by installing detectors in rooms opening onto escape routes (Category L3). For the earliest possible warning detectors could be installed in all rooms and certain sized void areas (Category L1).

Where can detectors be installed?

Detectors can be installed in any room/environment, it is about the designer choosing the most appropriate type of detector for the environment it is being installed in.

  • Ionisation detection – detects small invisible particles of smoke given off by flaming fires, so you will be alerted at the earliest stages of a fire. As this is a very sensitive detector positioning is very important to minimise the risk of false alarms from normal activities.
  • Optical detection – detects visible particles of smoke given off by slower burning/smouldering fires, which produce thick smoke. This is the most commonly installed detector as it provides early warning with a low risk of false alarms.
  • Heat detection – detects either rapid increases in temperature or when a fixed temperature is reached. This type of detector is used in Kitchens, Garages, Warehouses and other harsh environments where smoke detectors would produce false alarms from normal activities.

Other types of specialist detection can be installed to provide early detection in tough
environments such as processing plants, workshops etc.

What can you do for me?
