Aspirating Fire Detection
Very early warning smoke detection using aspirating systems. Ideal for data centres, heritage buildings, clean rooms, and high-value environments across Bristol and the South West.
24/7 SupportDetection Capabilities
Aspirating systems provide the earliest possible smoke detection — detecting fire at its incipient stage.
Air Sampling Detection
Continuous air sampling through pipe networks for the earliest possible smoke detection in critical environments.
VESDA Systems
VESDA aspirating smoke detection with laser-based particle analysis and multi-level alerts.
Multi-Level Alerting
Pre-alarm, action, fire 1, and fire 2 sensitivity thresholds for graduated response before full alarm.
Data Centre Protection
Purpose-designed systems for server rooms, data centres, and clean rooms requiring very early warning.
High Airflow Environments
Effective detection in environments with high air movement where point detectors may be unreliable.
Heritage & Listed Buildings
Discreet, concealed sampling pipe installation for heritage buildings where visible detectors are unsuitable.
