The Model T-10 Time Delay is a factory pre-set mechanical time delay which retards the system discharge for a period of 10-20 seconds after actuation to allow for exhaust fan wind -down. The time delay is field mounted between the Pyro-Chem control head (Models MCH, NMCH, ECH-24, or ECH-120) and the discharge valve assembly of the agent cylinder(s) and/or pneumatic actuating cylinder(s).

Time Delay 0015 vc Chapter 3 — System Desigr Page 3-1 CHAPTER III SYSTEM DESIGN General Pyro-Chem Industrial Vehicle Paint Spray Booth Fire Suppression System has been designed and tested for use in commercial vehicle paint spray booth applications. The guidelines listed in this chapter deal with the limitations and parameters of various system configurations. It is the responsibility of the Certified installer to ensure that the proper system design is being utilized, and that the system meets the limitations and parameters listed in this chapter. Before attempting to design any system, it is necessary to attend a Factory Certification Training Class and become Certified to install Pyro-Chem Industrial Vehicle Paint Spray Booth Fire Suppression Systems. Because it is impossible to completely understand every aspect of a pre-engineered system simply by reading the Technical Manual, Pyro-Chem will not be responsible for system design, installation, or maintenance performed by any non -Certified person(s). Choosing the Proper Agent Designing the Proper Type of System It is necessary for the system designer to consider the phys- ical characteristics and layout of the hazard area to ensure proper protection. The hazard area must meet the criteria for a particular system for that system to be effective. Each noz- zle is tested and designed to protect a certain part of the total hazard area. In order to comply with the approval requirements of UL 1254 Standard, when protecting a Vehicle Paint Spray Booth, no unclosable openings are allowed. The system must also contain a discharge time delay. The ventilation system must be shut down before or simulta- neously with the discharge of the system.

(0 *C. to 48 *C.), ABC (monoammonium phosphate -based) - for use with all A", "B", and "C" Class hazards. d. Piping Requirements: As per NFPA 17, pre-engineered dry chemical systems are not approved for deep-seated or burrowing fires (such as ordinary combustibles where the agent cannot reach the point of combustion), or on chemicals that contain their own oxygen supply (such as cellulose nitrate). Do not mix differ- ent types of agents, or agents from different manufacturers. Chemical reactions may occur when incompatible chemicals are mixed. Keep in mind that the agent must be accept- able to the Authority Having Jurisdiction. Piping diagrams include limitations on pipe length and fit- tings. See the following pages for specific piping design and limitations for each size cylinder. ULEX 3437 CEx73: September 29, 1991 hapter 3 — System Design age 3-2 e. Nozzle Placement: The nozzle is to be mounted in the center (See Note) of the protected area, with the discharge holes in the nozzle no greater than four (4) inches from the ceiling.

ULEX 3437 CEx732 September 29, 1998 Chapter 3 — System Design Page 3-16 Detector Placement Thermal detectors are required in all hazard areas protected by the Pyro-Chem Vehicle Paint Spray Booth Industrial Fire Suppression System if automatic system operation is required. Either mechanical or electrical thermal detectors can be used for automatic system operation. Mechanical detectors (fusible links) are used in conjunction with the Pyro-Chem Models MCH, NMCH, and EN-MCU control devices. Electrical detectors are used in conjunction with the Pyro-Chem Models ECH-24 and ECH-120 Control Heads. A temperature survey must be performed to determine the maximum ambient temperature of the hazard survey. The detectors used to protect a hazard area must be at least 70OF above the maximum ambient temperature. The minimum number of thermal detectors (either mechani- cal or electrical) required for each hazard area is one detec- tor for each twenty-five (25) pounds of agent required in that hazard area. To determine the number of detectors required in a particular hazard area, divide the total amount of agent required for that hazard area by 25 and round up. Keep in mind that at least one detector is required in every protected hazard area. Additional detectors may be used to achieve taster system response: however, do not exceed the detector limitations outlined in this manual. For detector location, evenly divide the protected hazard area into protected zones, with the number of protected zones equal to the number of detectors. Located a detector at the top center of each protected zone. ULEX 3437 CEx732 September 29, 1998
