Benefits of Our Commercial Fire & Smoke Alarm Systems
Fire protection you can depend on, maximising safety while minimising downtime, disruption and false alarms.
Slash False Alarm Rates
Our systems average just one false alarm every 6 years. That’s because we position detectors perfectly and set them up properly. Fewer false alarms mean fewer disruptions and more reliable protection.
Find Smoke Sources Quickly
Addressable systems tell you exactly which detector triggered the alarm. No searching room by room, and faster resolution of minor alerts. Emergency services arrive on site knowing just where to look.
Tidy, Wire-Free Options
Wireless fire detection for buildings where running cables isn’t practical, or discreet VESDA sampling points to protect interiors. Clean installs that don’t disrupt decorations or operations.
Audit-Ready Documentation
Every detector mapped, every test logged, and all records stored in an online portal for easy access. Inspectors and insurers get the proof they need without you hunting for paperwork.

FAQs
What types of fire alarm systems do you install?
We install addressable fire alarm systems, conventional systems, wireless fire detection, and VESDA aspirating smoke detection. Addressable systems are best for most businesses because they tell you exactly where smoke or fire is detected. VESDA systems detect the earliest signs of fire, even before they ignite fully.
Do you offer fire alarm maintenance and servicing?
Yes. We maintain the systems we install and take over maintenance for systems installed by others. Regular servicing ensures your fire alarms will always work when needed.
How often should my fire alarm system be tested?
Weekly alarm tests by your staff, plus professional maintenance every 6 months. We handle the professional servicing and give you simple instructions for weekly tests.
Can you integrate fire alarms with other security systems?
Yes. We can link your fire alarms to your security systems, access control, and CCTV. Integration means better protection and easier management.
How long does fire alarm installation take?
Small offices take 1-2 days. Larger buildings take longer depending on size and complexity. We’ll give you exact timescales after surveying your site.
