Services
AOV Single Zone
Single zone AOV systems control smoke and natural ventilation in unified spaces. These panels trigger all connected actuators simultaneously, ideal for stairwells and small buildings. Compliant with EN:12101 standards, they integrate with fire systems or operate standalone. Available in 2.5A-10A configurations with battery backup.
AOV Multi Zone
Multi-zone AOV systems manage independent ventilation zones in complex buildings. Configurable from 5-20A capacity, they allow selective zone activation while supporting master zone chimney effects. Modular design enables expansion up to 15 zones with individual zone cards for commercial applications.
Actuators
24V DC actuators for window and vent operation in smoke control systems. Available in 380-1000mm reach with multiple mounting options. Designed for 1.35A-2A operation with safety-rated force outputs from 300-400N, compatible with all AOV control panels.
Detectors
EN54-certified smoke detectors with auto-reset bases for AOV systems. Operating between -10C to +50C, these detectors feature LED indicators and manual reset options. Designed for 9.5-30V DC operation with low current consumption.
Call Points
Manual call points for AOV system activation, including break-glass, keyswitch, and rocker switch variants. Rated for 30V DC operation with durable ABS enclosures. Available in single-zone or all-zone configurations for emergency override.
