Professional Commercial Fire Alarm Installation
BAFE-accredited fire protection for businesses across Kent, London & East Sussex.
Your Legal Obligations as a Business
Under the Regulatory Reform (Fire Safety) Order 2005, every non-domestic premises in England and Wales must have a suitable fire detection and warning system. The responsible person - typically the employer, owner, or occupier - is legally accountable for ensuring compliance.
-
Appoint a Responsible Person
Someone must be formally accountable for fire safety on your premises. This is typically the business owner, employer, or facilities manager.
-
Conduct a Fire Risk Assessment
All non-domestic premises must have a current, documented fire risk assessment. This must be reviewed regularly and updated when circumstances change.
-
Install & Maintain a Compliant System
Your fire detection and warning system must be appropriate for your premises, installed to BS5839 standards, and maintained at regular intervals.
Failure to comply with the RRO 2005 can result in prosecution, unlimited fines, and in serious cases, imprisonment.
Choosing the Right System for Your Premises
Conventional Systems
Best suited to smaller premises with straightforward layouts. The system identifies which zone has triggered but not the specific device. Cost-effective for smaller buildings.
Ideal for:
✅Small offices and retail units
✅Single-floor premises
✅Lower-risk environments
Not sure which system your premises requires?
S5839 provides guidance based on building size and risk level. Our engineers will recommend the correct system at survey stage.
Addressable Systems
Each detector has a unique address, allowing the panel to identify the exact device that has triggered. Essential for larger or more complex buildings.
Ideal for:
✅Multi-floor commercial buildings
✅Warehouses and industrial premises
✅Schools, care homes and hospitality venues
Cause & Effect Programming
Modern addressable fire alarm systems can be programmed to trigger automatic responses across your building when an alarm activates. This is known as cause and effect programming, and it's a critical safety feature for complex commercial premises.
-
HVAC Shutdown
Automatically closes air handling units to prevent smoke spreading through ventilation systems.
-
Lift Recall
Returns lifts to ground floor and holds doors open to assist evacuation and prevent entrapment.
-
Door Release
Releases magnetic door holders on fire doors, allowing them to close and contain the spread of fire.
-
Sprinkler Activation
Triggers sprinkler zones in response to specific detector activation in high-risk areas.
-
Gas Shutoff
Closes gas solenoid valves automatically to remove fuel sources in kitchens or plant rooms.
-
Access Control Integration
Releases electronically held doors to ensure all escape routes are immediately accessible.
