Coxdome Automatic Opening Ventilator

The Jet Cox FireJet EN12101-2 Range provides a smoke and heat exhaust ventilation system for all Commercial and Residential applications. Supplied factory assembled and factory tested all products are certified to CE EN12101-2. 

FireJet rooflights not only help to provide smoke extraction in the event of a fire but they also provide day-to-day controllable ventilation.

The Jet Cox FireJet range complies with the latest Building Regulations on Fire Safety and can be integrated into any Building Management System. Linked to a central control panel, complete with a battery backup system in case of mains failure, the control panel can be triggered from either manual override switches local to the ventilator and the ground floor, by dedicated smoke detectors, or by interfacing with a third party smoke detection/fire alarm system.

The FireJet Range is available with CLEAR or DIFFUSED polycarbonate glazing to enhance the buildings natural daylight.
