Description
The Hevac DPFC designed for fire mode operation of upto two stairwell pressure control loops & one lobby/corridor pressure relief fan systems, is hardware based on our tried & proven carpark ventilation controller HCP7.
The controller measures three 0-10v pressure sensor inputs (via external signal selectors) & produces three 0-10v outputs using P+ I plus one common relay output for optional fire mode run interlocks.
Modbus communication port allowing monitoring of all INPUT/OUTPUTS plus allowing temporary limited fire mode run override for commissioning & testing by BMS system.
PRE-PROGRAMMED with typical settings but fully site configurable to your nominated requirements with free on going technical support & a connection drawings.
Recommended stairwell differential pressure sensors are the Siemens QBM2030 DP sensors … see https://hevac.com.au/product/qbm2030-pressure-air-differential-sensor-0-10vdc0-100pa/
