The Smoke Aspiration System FL0122E is identical to the system FL2011EI, but the FL0122E has connections for 2 separate pipe networks and therefore can monitor 2 independent areas. The smoke aspiration system contains 2 separate sensing chambers, each with its own laser smoke detector, fan and filter as well as separate ultrasonic air flow monitoring. Two multi-segment LED displays indicate the relative air flow separately for each channel. The system is connected to the fire detection control panel via the integrated dry relay contacts
