Designed for flat and low-pitch roofs (0°–15°), this electrically operated smoke vent window combines functionality, safety, and smart design to provide essential smoke and heat extraction in the event of a fire.
How It Works – Intelligent Safety in Action
In the event of smoke detection or fire, the CSP window opens automatically within 60 seconds, allowing smoke and heat to escape through the roof. This helps:
Create smoke-free escape routes,
Improve visibility for evacuation,
Reduce heat and prevent flashover,
Facilitate fire-fighting operations.
The system is activated via connected safety components such as a smoke detector, control unit, or manual break glass point. It also allows for day-to-day ventilation when required.
