Fire detection and alarm systems are essential safety mechanisms designed to detect early signs of fire—such as smoke, heat, or flame—and raise an alert through audible and visual signals. These systems are a vital part of any property’s fire safety strategy, helping to minimise damage, protect lives, and support quick evacuation.
At RCD Electrical, we specialise in the design, installation, and maintenance of compliant fire detection and alarm systems for both residential and commercial properties throughout London.
Key Components of a Fire Detection System
Understanding the elements that make up a reliable fire detection and alarm system can help you appreciate its complexity and importance. The main components include:
-
Control Panel: The central brain of the system that monitors sensor input and triggers alarms.
-
Smoke and Heat Detectors: Devices that sense the presence of smoke or significant temperature rise.
-
Call Points (Manual Break Glass Units): Allow individuals to manually activate the alarm in case of fire.
-
Sounders and Visual Alarms: Audible sirens and flashing lights that alert occupants to evacuate.
-
Batteries and Backup Supply: Ensure the system operates even during power failures.
All of these elements must be correctly installed and regularly maintained to guarantee optimal function.
Professional Installation by RCD Electrical
Choosing RCD Electrical for your fire detection and alarm system ensures a professional approach grounded in compliance with BS 5839-1:2017 standards. Whether you’re fitting a new system or upgrading an existing one, our process includes:
-
Risk Assessment – We assess the layout and use of your premises to design a system that meets legal requirements.
-
System Design – Tailored placement of detectors and alarms for maximum coverage and response efficiency.
-
Certified Installation – Carried out by NICEIC-approved electricians with experience in fire safety systems.
-
Testing & Commissioning – Verifying that all components are fully operational before sign-off.
Legal Compliance and Responsibilities
Under the Regulatory Reform (Fire Safety) Order 2005, non-domestic premises must have an appropriate fire detection system in place. The law requires the ‘responsible person’—typically the business owner or landlord—to ensure:
-
All fire alarms and detectors are tested regularly.
-
The system is maintained by a competent person.
-
Logs of testing, faults, and servicing are kept up to date.
Non-compliance could lead to enforcement action, fines, or even criminal prosecution in the event of a serious incident.
Maintenance and Periodic Inspections
Regular maintenance is essential for system reliability. At RCD Electrical, we offer scheduled servicing packages, which typically include:
-
Testing of all detectors and call points
-
Inspection of control panels and batteries
-
Verifying sounders and visual indicators
-
Reviewing logbooks and records
Our inspections follow a quarterly and annual routine, ensuring that systems are always ready to operate in emergencies.
Domestic vs Commercial Fire Systems
While the principles are the same, the approach differs slightly between domestic and commercial installations.
-
Domestic Systems are generally simpler, often combining smoke alarms and heat detectors powered by the mains with battery backup.
-
Commercial Systems are more advanced, involving zoned detectors, addressable panels, multiple sounders, and integration with fire doors or emergency lighting.
RCD Electrical is equipped to handle both, offering a tailored approach to suit each environment.
The Cost of Neglect
Failing to install or maintain a fire detection system can have devastating consequences:
At RCD Electrical, we view fire safety not as a box-ticking exercise, but as a serious commitment to human life and building integrity.
