1.0m² Hatch Vent

With a choice of Polycarbonate or Sandwich Panel lid, our low profile hatch vent can be installed onto flat or sloping roofs providing ventilation.  Certified to EN 12101-2 this vent provides discharge of smoke and fumes with an opening angle of 140 degrees.

EV-301 Smoke Ventilation AOV Control Panel with Battery Back-up

Firemans Override Switch

Providing local override control with a visual and audible indication in accordance with BS EN 12101 Part 9 and BS ISO 21927 Part 9.  Two buttons provide override open, close and reset functions and three coloured LEDs with an audible buzzer indicate system health, fault and alarm status.
