Services
Fire Alarm Systems
We design and install analogue addressable and conventional zoned fire alarm systems compliant with BS5839 and EN54 standards. These systems integrate with emergency services via client-specified alarm receiving centres for off-site monitoring. Our open-protocol approach ensures clients are not tied to single-source providers, offering flexibility and long-term cost efficiency.
Emergency Lighting
Our emergency lighting solutions ensure safe evacuation during power failures, maintaining illumination for at least three hours. Systems include escape lighting for evacuation routes and standby lighting to sustain operations. Exit signs are illuminated in recognisable colours, remaining visible even during prolonged outages to meet regulatory compliance.
Dry Risers
Dry risers are installed in buildings 1860 meters tall, providing firefighters with water access on every floor. We conduct biannual visual inspections and annual pressure tests to ensure operational readiness. Systems are fitted in protected stairwells, with outlets positioned for rapid deployment during emergencies.
CCTV Installation
We supply and install high-quality CCTV systems tailored to indoor and outdoor environments. Solutions include infrared cameras for low-light areas, pan-tilt-zoom domes for remote monitoring, and integrated digital systems. Our installations support both simple single-camera setups and complex multi-camera networks for comprehensive security coverage.
AOV Systems
Automatic Opening Vent (AOV) systems control smoke dispersion, enhancing evacuation safety. They integrate with fire alarms to activate vents automatically during incidents. Regular testing ensures reliability, while additional features like comfort ventilation and roof access support both safety and functional building management.
