ASME A17.12007 2.8.3 Pipes, Ducts, Tanks, and Sprinklers 2.8.3.1 Steam and hot‐water pipes shall be permitted to be installed in hoistways, machinery spaces, machine rooms, control spaces, and control rooms for the purpose of heating these areas only, subject to 2.8.3.1.1 through 2.8.3.1.3. 2.8.3.1.1 Heating pipes shall convey only low‐pressure steam [100 kPa (15 psi) or less] or hotwater [100°C (212°F) or less]. 2.8.3.1.2 All risers and return pipes shall be located outside the hoistway. When the machinery space, machine room, control space, or control room is located above the roof of the building, heating pipes for the machinery space, machine room, control space, or control room shall be permitted to be located in the hoistway between the top floor and the machinery space, machine room, control space, or control room. 2.8.3.1.3 Traps and shutoff valves shall be provided in accessible locations outside the hoistway. 2.8.3.2 Ducts shall be permitted to be installed in the hoistway, machinery space, machine room, control space, or control room for the purpose of heating, cooling, ventilating, and venting these areas only and shall not encroach upon the required clearances. 2.8.3.3 Sprinkler systems conforming to NFPA 13 or the NBCC, whichever is applicable (see Part 9), shall be permitted to be installed in the hoistway, machinery space, machine room, control space, or control room subject to 2.8.3.3.1 through 2.8.3.3.4. 2.8.3.3.1 All risers and returns shall be located outside these spaces. Branch lines in the hoistway shall supply sprinklers at not more than one floor level. When the machinery space, machine room, control space, or control room is located above the roof of the building, risers, return pipes, and branch lines for these sprinklers shall be permitted to be located in the hoistway between the top floor and the machinery space, machine room, control space, or control room. 2.8.3.3.2 In jurisdictions not enforcing the NBCC, where elevator equipment is located or its enclosure is configured such that application of water from sprinklers could cause unsafe elevator operation, means shall be provided to automatically disconnect the main line power supply to the affected elevator and any other power supplies used to move the elevator upon or prior to the application of water. (a) This means shall be independent of the elevator control and shall not be self‐resetting. (b) Heat detectors and sprinkler flow switches used to initiate main line elevator power shutdown shall comply with the requirements of NFPA 72. (c) The activation of sprinklers outside of such locations shall not disconnect the main line elevator power supply. See also 2.27.3.3.6. 2.8.3.3.3 Smoke detectors shall not be used to activate sprinklers in these spaces or to disconnect the main line power supply. 2.8.3.3.4 In jurisdictions not enforcing the NBCC, when sprinklers are installed not more than 600 mm (24 in.) above the pit floor, 2.8.3.3.4(a) and (b) apply to elevator electrical equipment and wiring in the hoistway located less than 1 200 mm (48 in.) above the pit floor, except earthquake protective devices conforming to 8.4.10.1.2(d); and on the exterior of the car at the point where the car platform sill and the lowest landing hoistway door sill are in vertical alignment. (a) Elevator electrical equipment shall be weatherproof (Type 4 as specified in NEMA 250). (b) Elevator wiring, except traveling cables, shall be identified for use in wet locations in accordance with the requirements in NFPA 70.

Ed Aero Automatic Sprinkler -----Original Message----- From: sprinklerforum-boun...@firesprinkler.org [mailto:sprinklerforum-boun...@firesprinkler.org] On Behalf Of Charles Thurston Sent: Thursday, March 03, 2011 11:30 AM To: sprinklerforum@firesprinkler.org Subject: Re: Electrical Rooms Hello Ed.Tambini, I know here that anything that enters the elevator room can not exit the room unless it goes directly into the shaft. Had a building that had been here 20 years, Got a new owner who did the typical paint/wallpaper make over. When the elevator inspector came out the sprinkler pipe passing through the equipment room on the roof to a mechanical room on the roof had to be removed before he would certify the elevator. The pipe was rerouted from the floor below, Had to tear out a bunch of finished work to do the coring.
