Product Description
TYCO Type D3 Protectospray Medium Velocity Directional Spray Nozzles
 
 
General Description
 
The TYCO Type D3 PROTECTO-SPRAY Nozzles are open (non-auto-matic) directional spray nozzles and they are designed for use in water spray fixed systems for fire protection applications. They are external deflec-tor type nozzles that discharge a uni-formly filled cone of medium velocity water droplets.
 
The D3 Nozzles are effective in cov-ering exposed vertical, horizontal, curved, and irregular shaped surfaces in a cooling spray to prevent exces-sive absorption of heat from an exter-nal fire and possible structural dam-age or spread of fire to the protected equipment. In some applications, de-pending on water design density re-quirements, the Type D3 Nozzles may also be used for fire control or extinguishment.
 
The Type D3 Nozzles are available in a wide variety of orifice sizes and spray angles (included angle of discharge)­ to provide versatility in system design. Refer to Technical Data Sheet TFP890 for information on Blow-Off Plugs that can be used for applications where protection is required against insect infestation or accumulation of debris within the nozzle orifice.
 
It is recommended that the end user be consulted with respect to the suit-ability of the materials of construc-tion and finish for any given corrosive environment­. The effects of ambient temperature,­ concentration of chem-icals, and gas/chemical velocity,should be considered, at a minimum, along with the corrosive nature to which the sprinklers­ may be exposed.
 
The Type D3 PROTECTOSPRAY Noz-zle is a re-designation for the Gem Type D3.
 
NOTICE
 
The Type D3 PROTECTOSPRAY Noz-zles described herein must be in-stalled and maintained in compliance with this document, and with the ap-plicable standards of the National Fire Protection Association, in addition to the standards of any authorities having jurisdiction. Failure to do so may im-pair the performance of these devices.
 
The design of individual water spray fixed systems can vary considerably, depending on the characteristics and nature of the hazard, the basic pur-pose of the spraying system, the con-figuration of the hazard, and wind/ draft conditions. Because of these variations as well as the wide range of available nozzle spray characteristics, the design of water spray fixed sys-tems for fire protection must only be performed by experienced designers who thoroughly understand the limi-tations as well as capabilities of such systems.
 
The owner is responsible for maintain-ing their fire protection system and devices in proper operating condition. The installing contractor or sprinkler manufacturer should be contacted with any questions.

Design
Criteria
 
Nozzle Placement. Where direct im-pingement of water spray onto all of the protected surface is required by the authority having jurisdiction, the nozzles are to be spaced and directed so that their spray patterns will com-pletely cover the plane-of-protection with the minimum required average density; however, it is recommend-ed that indoor nozzle spacing be 12 feet (3,7 m) or less and that outdoor nozzle spacing be 10 feet (3,0 m) or less. Where rundown or slippage is planned, such as, exposure protec-tion of vessels per NFPA 15, the above recommended­ indoor and outdoor spacings­ also apply.
 
When used for protecting the surfaces of a vessel, for example, the nozzles are positioned normal to and approxi-mately 2 feet (0,6 m) from the surface. This approach, in conjunction with a properly selected spray angle, will tend to make more effective use of the spray as well as help minimize the dis-turbance effects of wind/draft condi-tions on the water spray patterns.
 
Spray Patterns. The Design Spray
Profiles for the nozzle spray angles of 65 to 180 degrees are shown in Fig-ure 2 and apply to discharge pres-sures of 20 to 60 psi (1,4 to 4,1 bar). Discharge pressures in excess of 60 psi (4,1 bar) will result in a decrease in coverage area since the spray pat-terns tend to draw inwards at higher pressures. Refer inquiries on higher discharge pressures to the Technical Services Department. The maximum axial distances between the nozzle tip and plane-of-protection, for exposure

Main Pipeline Strainers. Main pipe-
line strainers per NFPA 15 are required for systems utilizing nozzles with a flow path less than 3/8 inch (9,5 mm) diameter, i.e., No. 16 thru No. 24 (Ref. Table A), and for any system where the water is likely to contain obstructive material.
