The Two Sides of Fire Alarm Installation

I often explain to learners that fire alarm installation has two pillars—the installation side and the electrical side.

The Installation Side

This is the practical, hands-on craft:

• Designing systems with smoke, heat, or multi-sensor detectors.
• Positioning alarms and sounders for effective coverage.
• Running fire-resistant cables safely.
• Commissioning systems to BS 5839 standards.

👉 Our Domestic Fire Alarm Course, run at our Cheshunt training centre in Hertfordshire, teaches you how to install Grade D systems (BS 5839-6) for homes and HMOs. Many of our learners join us from Broxbourne, Waltham Cross, Enfield, and Essex.

The Electrical Side

This is where compliance and safety come in:

• Following the 18th Edition Wiring Regulations (BS 7671).
• Ensuring safe mains connections and battery backups.
• Integrating alarms with sprinklers, security, and emergency lighting.
• Meeting Part P Building Regulations.

👉 Our Commercial Fire Alarm Course prepares learners from Hertfordshire, North London, and beyond for BS 5839-1 systems, including schools, offices, and commercial buildings.

Why BAFE Certification Matters

Training gives you skills. Certification proves your competence.

The BAFE Register is the UK’s leading independent fire safety certification.

• SP203-1 covers commercial systems (BS 5839-1).
• DS301 covers domestic systems (BS 5839-6).

While not legally required (BAFE FAQ), I’ve seen how BAFE certification gives contractors credibility—particularly in areas like London, Hertfordshire, and Essex, where local authorities and housing providers increasingly expect it.
