ZONE GUARDIAN Residential

Sale Engineering Products is excited to be able to supplement its existing ZONE GUARDIAN range with three sizes in two materials, for residential (or other small bore pipe) applications.

The residential ZONE GUARDIAN is a device which allows the testing of a fire sprinkler system’s waterflow detector (flow switch) to be carried out remotely, saving both time and
cost for end-users and maintenance contractors.

The unit ensures zero wastage of water by the use of an artificial water flow created using a high-efficiency self-venting circulator pump manufactured by a global supplier.

The assembly is available in either steel or CPVC pipe sizes of 1”/25mm, 1¼”/32mm and 1½”/40mm and includes – as well as the circulator pump – a Potter VSR vane-type flow switch with adjustable retard, and ball valves for pump isolation.

The unit may be installed horizontally (with flow switch on top) or vertically (with upward flow).

An electronic key-operated test module is included to allow testing of both the local and any interconnected waterflow detectors.

We are confident that our new residential ZONE GUARDIAN, backed up by SEP’s history of providing quality products to the market will prove as popular as our standard ZONE GUARDIAN.

ZONE GUARDIAN is stocked by and available through our exclusive distributor, Zeffire Ltd, as well as directly from SEP.
