It is really very clear that aspirated system is the best fire alarm detection system in terms of sensitivity and reduction of false alarms..., but if by accident some pipes has been distroyed in the middle, how can aspirated system control unit monitors such problem....?
As open circuit in ordinary conventional or addressable systems is  provided is not it?
