AOV Kit B – 1.0m² Louvred Stair Vent and Controls comprises of:

1.0m² Louvre Vent

With a choice of insulated aluminium or opal polycarbonate blades, this maintenance-free, CE-marked, EN 12101-2 certified and lightweight louvred ventilator for natural ventilation and smoke and heat extraction, provides discharge of smoke and fumes through the motorised blades along the length of the frame.

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

The CE-marked for smoke control use (tested to EN 12101), control panel monitors and controls smoke control ventilators and interface devices all with the added security of a battery back-up.  The innovative design provides a programmable facility (via DIP switches) for limited ventilation (used on day-to-day ventilation to prevent AOV windows opening fully) and timed openings used in conjunction with a thermostat for corridor cooling.

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.
