Dry Risers – Inlet and Outlet Cabinets
Dry Riser systems are based, quite simply, on an inlet (‘inlet breeching’ on the outside wall of a property) and a series of outlets (Gate or Landing Valves) at each floor (internally) of a property which are principally located in lobbies, fire shafts or stairwells. Both inlet and outlet have to be protected from possible occurrences that deter from acceptable use in an emergency situation. This may be in the form of accidental damage, vandalism, debris build up or obstruction.
For this reason it is required that both inlet breechings and outlets (gate valves) are housed in red protective glass fronted cabinets.
These cabinets are normally marked with the words ‘Dry Riser Inlet or Dry Riser Outlet” for ease of recognition and should be kept locked shut at all times.
The glass fronts are designed to be broken in an emergency situation allowing for full access by Fire and Rescue crews and subsequent hose connection. We can offer replacement glass for our cabinets.
Delta Fire supply both inlet cabinets and outlet cabinets as part of their Dry Riser range of products. Both cabinets are manufactured in epoxy powder coated mild steel and have a wired Georgian glass door complete with a Yale lock. They are available as recessed with a 30mm architrave (most common, see photo above) or we can offer surface mounted cabinets on request which are made to order.
The dry riser Inlet Cabinets are fully compliant to BS5041 Part 4 and comes with standard measurements of 595mm (w) x 395mm (h) x 295mm (d) for the 2-way horizontal version and 395mm (w) x 595mm (h) x 295mm (d) for the 2-way vertical version. The 4-way inlet cabinet again comes with standard measurements of 595mm (w) x 595mm (h) x 295mm (d)
The inlet cabinet / breeching inlet should be positioned as closely as possible to the rising main in order to reduce the pressure loss and within easily accessible reach of the attending fire appliance which should be in un-obscured sight of fire crews and no more than 18 metres away from the nearest vehicular access.
The Outlet Cabinets are equally compliant to BS5041 Part 5 but the measurements are varied depending on the size of the gate valve is houses. The outlet cabinets are also available as architrave and door only (without backs).
In respect of the outlet cabinet / gate valve positioning, BS9990 2006 requires that the outlet valve must be installed with it’s lowest point at 750mm above floor level.
As with all Delta Fire’s range of Dry Riser products, the cabinets are manufactured to a high standard and are used widely by a diversity of clients including construction based industries and industrial users etc.
