Commercial Fire Alarm Systems Designed for Your Building
Every building is different. We design and supply commercial fire alarm systems across Hull and East Yorkshire that are built around your layout, risk profile, and compliance requirements under BS 5839-1.
Addressable Fire Alarm Systems
Ideal for larger or multi-zone premises, addressable systems identify the exact device triggered, making fault finding faster and improving system management.
Conventional Fire Alarm Systems
A cost-effective solution for smaller commercial premises, with detection grouped into zones for straightforward protection.
Wireless Fire Alarm Systems
Flexible systems suited to listed buildings, refurbishments, or projects where cabling is impractical or disruptive.
Which Fire Alarm Category Does Your Building Need?
Commercial fire alarm systems are classified into categories under BS 5839-1 — the British Standard that governs the design, installation and maintenance of fire detection systems. The correct category for your premises is determined by your building layout, occupancy type and fire risk assessment. Getting this right isn’t just about compliance — it’s about ensuring the right level of protection for your people, your assets and your business continuity.

Frequently asked questions about commercial fire alarm systems in Hull
The cost of a commercial fire alarm system depends on the size of your premises, the type of system required and the category specified under BS 5839-1. A conventional system for a small commercial unit will cost considerably less than a fully addressable system across a large warehouse or multi-floor office building. We carry out a free site survey and provide a detailed, itemised quote before any work is agreed — so you’ll know exactly what you’re getting and what it costs before committing to anything.
A conventional system divides your building into zones — when a detector activates, the panel tells you which zone it’s in but not the exact device. An addressable system gives every detector its own unique address, so the panel pinpoints exactly which device has triggered. For larger premises, multi-floor buildings or anywhere with complex layouts, addressable systems make fault finding significantly faster and reduce unnecessary evacuations caused by false alarms.
Yes. Following installation or a major modification, your engineer should provide a commissioning certificate confirming the system has been installed and tested in line with BS 5839-1. This is an important document for your fire risk assessment records, insurance purposes and any future inspections. Cobra Fire and Security provides full documentation with every installation so your compliance paperwork is in order from day one.
For most small to medium commercial premises, installation is typically completed within one to two days. Larger or more complex sites may take longer depending on the number of devices, the extent of cabling required and any access restrictions. We’ll give you a realistic timeframe at the survey stage so you can plan around the work with minimal disruption to your business.
Yes — this is where our wireless fire alarm systems are particularly useful. Wireless systems require no cabling runs through walls or ceilings, making them ideal for listed buildings where drilling or chasing would cause damage, or for live refurbishment projects where running cables is impractical. They’re fully BS 5839-1 compliant and can be expanded or reconfigured as your building changes.
