Limitations detailed in this manual have been established through extensive testing by Underwriters Laboratories, Inc. Installation and maintenance of the system must conform to the limitations detailed in this manual and be per- formed by an Authorized PYRO-CHEM dealer. The PYRO-CHEM Open Face Paint Booth System utilizes a monoammonium phosphate based dry chemical agent (specifically designed to suppress carbonaceous solid, liquid, gas or electri- cal 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 shutdown of fuel and power to the hazard area is required upon system actuation. Exhaust fan(s) in the ventilation system must be shut off during system discharge to allow the proper concentration of agent to build up in the hazard area. TEMPERATURE LIMITATIONS The operating temperature range of the PYRO-CHEM Open Face Paint Booth System is 32 °F (0 °C) minimum to 120 °F (49 °C) maximum. UL LISTING The PYRO-CHEM Open Face Paint Booth Industrial Fire Suppression System has been tested to the UL Standard for Pre-Engineered Dry Chemical Extinguishing System Units. UL1254 (Revised Sept. 29. 1998), and Listed by Underwriters Laboratories, Inc. •CITY OF NEW YORK APPROVAL The PYRO-CHEM Open Face Paint Spray Booth Fire Suppression System is approved by the City of New York Fire Department per Certificate of Approval No. 5544 under the following condi- tions: 1. Prior to installation, plans must be filed with and accepted by New York City Department of Buildings.Additionally, a copy of New York City Department of Buildings docketed plans shall be transmitted to the Fire Department for review and approval. 2. The system shall be installed, periodically inspected, tested and otherwise maintained in accordance with Sections 901, 904.1.1 and 904.4 of New York City Fire Code, NFPA 17 and all applicable New York City Construction Code/Fire Code. Electrical wiring shall be in accor- dance with the New York City Electrical Code. 3. At least once a month, an inspection shall be conducted by a trained and knowledgeable person to assess that the system is in good working order. 4. The installation, maintenance procedures, and limitations stated in this manual must be corn- ,. plied with. • ULEX 3437 CEx732 February 1, 2010 Chapter 2-Components Page 2-2 REV.3 NOZZLES ,I�Nozzles have been developed for Open Face Paint Spray • Booth protection.
