Greg Heath Terry Mostul Mark Koester n 8 i CCB# 86723 -' O r . % b 13 Chapter 1 —General Page 1-1 REV. 1 CHAPTER General Information INTRODUCTION PYRO-CHEM Vehicle Paint Spray Booth automatic dry chemical fire suppression system is of the pre-engineered type as defined by the NFPA Standard for Dry Chemical Extinguishing Systems, NFPA-17.The extinguishing units described in this manual are intended to be installed, inspect- ed, and maintained in accordance with NFPA-17. Limitations detailed in this manual have been established through extensive testing by Underwriters Laboratories, Inc. Installation and mainte- nance of the system must conform to the limitations detailed in this manual and be performed by an Authorized PYRO-CHEM dealer. The PYRO-CHEM Vehicle Paint Booth System utilizes a monoammonium phosphate based dry chemical agent (specifically designed to suppress carbonaceous solid, liquid, gas or electrical fires). The system provides mechanical or electrical automatic actuation and can be manually actuated through a remote mechanical pull station. Upon actuation, the system discharges a pre-determined amount of agent to the hazard area. The sh down of fuel and power to the hazard area is required upon system actuation. Exhaust •fan(s) Irthe ventilation system must be shut off prior to system discharge to allow the proper concentration of agent to build up in the hazard area. The PYRO-CHEM Vehicle Paint Booth System is designed to accommodate a mandatory factory pre-set time delay.This time delay is required based on the UL 1254 compliance testing. TEMPERATURE LIMITATIONS • The operating temperature range of the PYRO-CHEM Vehicle Paint Booth System is 32 °F (0 °C) minimurp to 120 °F (49 °C) maximum. � UL L1STlNG The PYRO-CHEM Vehicle Paint Booth Industrial Fire Suppression System has been tested to the UL Standard for Pre-Engineered Dry Chemical Extinouisbing System Units.

UL 1254 Paragraph 28.2.6 states: The duct length and elevation shall be the maximum specified by the manufactur- er for protection by a single nozzle and shall also have the maximum number of changes in direction (turns) specified by the manufacturer. Longer lengths of duct and greater number of changes in direction are to be protected using additional duct nozzles." PYRO-CHEM duct nozzles have not been UL tested to cover any turns in direction in the duct line.The use of 90° and multiple 45°changes that results in a vertical to horizontal change of direction constitutes additional nozzle coverage and dry chemical agent.The nozzle must be centered in the duct and aimed in the direction of the airflow. Protection is also required before and after any obstructions such as fans or dampers in the duct line. If a fan or damper is located at the duct entrance, the nozzle must be placed immediately after the fan or damper, to a maximum of 2 ft. (.6 m) from the duct opening.The entire exhaust ductwork must be pro- tected. FMI PLENUM Figure 3-2c. • 007400 ULEX 3437 CEx732 September 1, 2006 Chapter 3—System Design Page 3-4 REV.2 •g.

These limitations apply to PCI-35ABC using three nozzles (1 NV-WA or NV-SW and 2 of any combination of NV-P1, NV-UF, or NV-DP2). 2. For systems that have been tested with unbalanced piping, the difference in the length of piping must not exceed 10% of the maximum unbalanced ratio tested. 3. A Main/Reserve Swing Check Valve, Part No.417788, may be located between the cylinder and T1. 4. All systems protecting vehicle paint spray booths require a factory pre-set time delay. 5. When using an NV-P1 nozzle, the two largest discharge orifices in the nozzle body must be positioned parallel to the longest dimension of the hazard being protected. 6. Model NV-WA or NV-SW nozzle must be located on "T1 to nozzle"branch only. /-1• 7. Maximum height of nozzle from base of tank to nozzle—20 ft. (6.1 m). �.i ULEX 3437 CEx732 ' September` ;:2f6'-:
