Countless fire breakouts are reported every year in Essex and London, and the impact they have on both people and properties is devastating. In 2024 alone, 16,608 incidents were reported in the county, with 3,723 due to fire emergencies. At IQ Fire Solutions, we continue to remind our customers how crucial it is to detect risks and take prompt action. Moreover, for commercial and residential buildings, this is a legal requirement as per the BS 5839 Standards.
While most ‘responsible persons’ understand the kind of safety a business demands, not everyone is aware of the correct type of fire alarm system needed to install in their commercial and residential properties. This guide helps you to pick the best one and safeguard your property, employees, and customers from fire-related dangers.

Fire Alarm Systems in London and Essex: Variants Designed for Various Requirements and Environments
Before we further discuss fire alarm systems installed within commercial and residential properties in Essex and London, have you ever wondered if you need one? The decision rests with the Regulatory Reform (Fire Safety) Order 2005 (FSO).
When engaging with fire alarm companies in London and Essex like IQ Fire Solutions, we require a copy of your fire risk assessment to allow us to determine any specific risk and the level of protection required to ensure the safety of all.
Now that you know the rule, let’s understand the fire alarm types and decide which one is the best:
- Non-Addressable Fire Alarm Systems
Non-addressable fire alarm systems use zonal divisions within a building. When an alarm sounds, the system immediately reveals the zone of activation, which aids occupants in quickly finding the potential fire. Despite lacking precise location identification, these systems offer a cost-effective solution for smaller businesses in buildings with simple layouts.
- Radio/Wireless Fire Alarm Systems
One of the greatest benefits of Radio Fire Alarm systems is they seldom require wiring to be installed on individual device. To guarantee a mains power connection, cabling is usually only needed for the control panel and signal boosters in contemporary configurations.
Due to the stated facts, experts recommend wireless fire alarm systems for historic or listed buildings. Since conventional cable installations are challenging, radio fire alarm systems make more sense. These setups provide a comprehensive fire detection solution without requiring structural disruption to the building.
The most successful installation has occurred in The Ritz Hotel and the Windsor Castle. Radio systems are the only practical way to comply with current fire safety standards and regulations because conservation authorities may not permit internal wiring in many protected sites.
- Addressable Fire Alarm Systems
Those looking for a more advanced fire alarm detection system in London must try the addressable system. Since every call point and component here has its address, the alarm system finds it easy to determine the device’s exact location. This system finds more meaning in larger commercial buildings with complex layouts. Unlike non-addressable/conventional systems, it’s more expensive but worth it.
- Hybrid Fire Alarm Systems
As the term implies, such systems combine wired and wireless elements, offering relentless flexibility. Customise the solution according to your requirements with wired detectors in new sections of your building and wireless ones in older parts.
When browsing the various alarm systems, it’s vital to know the difference between types and categories. While the former refers to ‘technical setup’, the latter implies ‘level of protection’. In British Standard 5839, you are more likely to find the mention of ‘categories’ in fire alarm systems, necessary for fire safety regulation compliance. At IQ Fire Solutions, we advise complying with this standard during design, installation, and maintenance to ensure your system’s compliance with the fire safety regulations.
How to Choose the Appropriate Fire Alarm System for Your Business in London?
Given the different choices in fire alarm system categories, business owners and operators might find it daunting to pick the right one. Therefore, here is a guide on ways to ensure your facilities are equipped with the best ones:
- Assess the Risk
The required thing to do is conduct a fire risk assessment according to the specifications laid down by the Fire Safety Order. It’s how you can identify the specific fire risks and determine the protection level necessary in your workplace.
- Determine the exact size and layout of your Commercial Facility
One of the most important deciding factors for choosing a fire alarm is considering the size and layout of the premises. The smaller the facilities and the simpler the building layout, the simpler a type of system can be considered. Larger and more complex buildings should be equipped with addressable or wireless alarm systems. It provides precise monitoring and control. The primary importance always focuses on the level of risk to life and the value of property.
- Recognise the high-risk Zones
Fire alarm system levels, often categorised using the letters L1-L5, represent the extent of life protection provided by an automated fire alarm system. These levels are based on the scope and intensity of protection, with L1 offering maximum protection and L5 being a more localised and customised system.
Here’s a breakdown of the key differences:
- L1: Maximum Life Protection: This level provides the most comprehensive life protection, including detectors in all areas of the building where a fire could start, such as rooms, roof spaces, and voids.
- L2: Additional Life Protection: This level focuses on escape routes and high-risk areas, offering a higher level of protection in these critical zones.
- L3: Standard Life Protection: L3 systems cover escape routes and adjoining rooms, providing a good balance of protection for most building types.
- L4: Modest Life Protection: L4 offers a more limited scope, focusing primarily on protecting escape routes only.
- L5: Localised Life Protection: This level is customised based on a fire risk assessment, offering protection for specific hazards identified in the building.
- Consider your budget
Just as robust fire safety is crucial, similarly, maintaining a budget is essential. Small businesses switching to non-addressable/conventional alarm systems benefit from more cost-effectiveness. For larger premises, addressable and hybrid systems may prove expensive but provide advanced features based on life protection and property risk as required by BS 5839 and often mandated by insurance requirements.
