Extended Coverage Sprinklers
An extended coverage sprinkler can protect a larger area on its own than a standard sprinkler thanks to its deflector design and flow. Using fewer sprinklers in the same area reduces pipework and installation labour.
It is preferred in open offices, corridors, hotel rooms and large spaces with flat ceilings; pendent, upright and sidewall types exist. The coverage area and required flow are set by the approved datasheet of the selected model.
Main Applications
- Open-plan offices
- Hotel and dormitory rooms
- Long corridors
- Flat-ceiling halls and foyers

Which material? As this type is not listed separately in the store, coverage area, flow and approval come from the selected model’s datasheet; an extended coverage sprinkler must only be used in the hazard class its datasheet allows.
