The DVG smoke extract fans are used in case of fire to extract smoke gases from rooms, and also during normal working conditions for standard ventilation. Smoke-free escape ways increase the chances to rescue people in case of fire. The casing is manufactured from seawater resistant aluminium. The base frame is made of pre-galvanized steel, zincmagnesium (ZM) coated. The impeller with backward curved blades is manufactured from pre-galvanized steel (sizes, ), respectively from steel, welded and galvanized (sizes 6 to 8). Motor outside air stream is cooled with fresh air. Connection to power supply in the service switch, connection to controller in the connection box on the casing.

Roof Fan DVG EC 9 Electrical accessories - connection examples If the fan is supposed for fire ventilation too, switch to fire mode must be controlled by fire control system. Electrical accessories Accessories (sensors with output -1V) for daily ventilation, controlled by internal PI regulator (integrated in fan) Setup of internal PI regulator via Modbus. For use of internal PI regulator two analog signals (-1V) are needed. First one, which defines target (set point) value of regulated property (temperature, humidity, CO2,..) with analog signal connected to AN1 (connection 7 at 1~, 6 at ~) Second one, which defines actual measured value of regulated property (temperature, humidity, CO2,..) with analog signal from sensor, connected to AN2 (connection 11 at 1~, 8 at ~) Systemair-E-D, humidity, temperature sensor DSG 2,, 1 differential pressure sensor / humidity / temperature Systemair-E-D Item no. 19 % C Differential pressure transmitter with built-in PID cotroller 12 9 TEMP 1 2 6 7 12 9 or RH% 1 2 6 7 12 9 or CO2 1 TEMP, -1V/-2mA (Jumper) 2 COM/GND RH%, -1V/-2mA (Jumper) - PT 1 + 6 CO2, -2mA 7 COM/GND 8 8 8 CO2, -1V/- (Jumper) MTP 2 on/off, -step manual speed controller MTV-1/1 controller for manual speed control Differential pressure DSG 2 DSG Item no. 169 Item no. 17 DSG 1 Item no. 966 MTP 1 Potentiometer for manual speed control 1 11 12 9 +2V Brown Output +...1V DC Yellow White + - S-EC/FRQ step switch for manual speed control Accessories with built-in PID controller + 12 9-1V DC - IN 2V AC/DC 1 2 6 7 8 9 Differential pressure transmitter with built-in controller with selectable range...1/ / / 1 Pa DMD-C Item no. 179 CO2RT-R-D sensor EC-Vent control board EC-Vent room unit
