Abstract: A smoke/pollution detection apparatus embodying a manifold valve assembly (11) including four inlet ports leading into a spreader cone (12) for deflecting gas/airstream, drawn from a plurality of zones under surveillance through a pipe reticulation system comprising a plurality of pipes communicating with said zones, from the manifold (11) around the top of a dust filter (10). A valve means including a reciprocating, rotating matching thin conical bell (14) situated over the cone (12) may be raised to an upward position where a hole (15) is arranged to be aligned with one of the ports such that the others are blocked, and gas/airstream from the particular pipe joined to the open port is sampled. Selective closing of the inlet ports to the assembly (11) allows the locality of a zone of any detected smoke/pollution to be quickly identified by the apparatus and in which all ports to the apparatus remain open under normal circumstances (no pollution detected) and all monitored zones remain coupled to a detector and there is no power drawn nor any movement of any parts including the valve means in the inoperative condition.
