SKU: SDP-3 Category: Brand:


The SDP-3 is a Duct Probe housing allowing a range of photoelectric smoke detection devices, either conventional or analogue addressable, to be mounted on the outside of an air duct for the purpose of monitoring the air within the duct.

Using an aspirating technique, the air within the duct is drawn via a pipe into the duct probe’s housing. This allows constant sampling with a standard, LPCB approved smoke detector, which makes smoke detection within the duct simple, effective and easy to maintain.
