(a) automatically admit water to the system by opening of a hose valve, and

(b) transmit a signal to an attended location.

(9) A standpipe riser shall be located in,

(a) an exit stair shaft, or

(b) a service space.

(1) If a standpipe system is required in a building, 38 mm diam hose connections shall be provided in each storey in the building.

(2) In addition to the requirements in Sentence (1), if a standpipe system is required, 65 mm diam hose connections shall be installed in each storey in the building if the building,

(a) is more than 25 m high, measured between grade and the ceiling of the top storey, or

(b) has a building area of more than 4 000 m².

(1) If a standpipe system is required in a building, hose stations shall be provided in each storey in the building.

(2) Each hose station shall be equipped with a hose rack filled with not more than 30 m of 38 mm diam fire hose and the hose rack and fire hose shall be,

(a) listed, or

(b) approved by the Factory Mutual Research Corporation.

(3) Except in a Group F occupancy, at each hose station, hose connections, valves, fire hose, nozzle and hose rack shall be in a hose cabinet.

(4) A hose cabinet referred to in Sentence (3) shall be of sufficient size to,

(a) contain the equipment referred to in Sentence (3),

(b) contain a listed fire extinguisher, and

(c) provide sufficient clearance to permit the use of a standard fire department hose key.

(5) Hose stations shall be located,

(a) so that every portion of the building can be reached by a hose stream and is within 3 m of a nozzle attached to the hose required in Sentence (2),

(b) not more than 5 m from every required exit serving a floor area, except,

(i) for the first storey, or

(ii) if additional hose stations are required to achieve full coverage of the floor area, and

(c) in a conspicuous location where they are not likely to be obstructed.

(6) Except as permitted in Sentence (7), hose stations shall be located so that it is not necessary to penetrate an exit with a hose in order to provide the design coverage required in Clause (5)(a).

(7) A hose is permitted to penetrate an exit in order to provide the required coverage to,

(a) a service room referred to in Sentence 3.2.9.1.(4),

(b) a roof-top enclosure referred to in Sentence 3.2.9.1.(5),

(c) a room not more than 50 m² in area, or

(d) a room or group of rooms not more than 200 m² in area in a sprinklered floor area.

(8) A hose station located on one side of a horizontal exit shall be considered to serve only the floor area on that side of the horizontal exit.

(9) A hose cabinet shall be located so that its door, when fully opened, will not obstruct the required width of a means of egress.

(10) A hose station in a Group B, Division 1 major occupancy is permitted to be located in a secure area, or in a lockable cabinet provided that,

(a) identical keys for all cabinets are located at all guard stations, or

(b) electrical remote release devices are provided and are connected to an emergency power supply.

(b) for not less than 30 min,

(c) at a pressure of not less than 450 kPa, and

(d) of not less than 945 L/min from each of the two outlets simultaneously.

(2) If the building is less than 84 m high, measured between grade and the ceiling level of the top storey, the water supply required in Sentence (1) is permitted to be supplied through the fire department connection.

(3) If the building is 84 m or more high, measured between grade and the ceiling level of the top storey, the water supply required in Sentence (1) shall be provided by sufficient pumping capacity.
