Fire Alarm Systems
When a fire breaks out, a fire alarm system gives you the earliest possible warning—alerting people the moment it detects smoke, heat, or flames. These fire safety systems can activate automatically using detectors or manually through a call point.
At Simply Extinguishers, we stock complete conventional fire alarm kits and all the individual components you might need—manual call points, sounders, beacons, power supplies, and fittings—perfect for new setups or upgrades.
What are the Main Types of Detectors used in Fire Alarm Systems?
There are four main types of detectors used in fire alarm systems:
- Photoelectric detectors spot smoke particles through light sensors.
- Ionisation detectors react to chemical changes caused by smoke.
- Heat detectors trigger once temperatures rise beyond a set level.
- Combination detectors blend photoelectric and ionisation for wider coverage.
Each type detects fire differently—through light, chemistry, or temperature—so choosing the right one depends on your environment.
Wondering which system is best for your premises? That depends on the layout, fire risk, and activity on site. The safest approach is to book a professional fire risk assessment. An assessor will guide you to the system that meets your legal duties and offers the best protection.
All fire alarm systems should follow BS 5839, the British Standard that outlines best practices for design, installation, commissioning, and maintenance of fire detection systems.
From small offices to large industrial sites, we’ve got everything you need to build a system that saves lives.
