Fire Suppression Systems

Pee Dee Fire & Safety closely follows the guidelines set forth in NFPA 96, the National Fire Protection Association's standard for Ventilation Control and Fire Protection of Commercial Cooking Operations. NFPA 96 sections 10.1.1 and 10.1.2 state: "Fire-extinguishing equipment for the protection of grease removal devices, hood exhaust plenums, and exhaust duct systems shall be provided" and "Cooking equipment that produces grease-laden vapors and that might be a source of ignition of grease in the hood, grease removal device, or duct shall be protected by fire-extinguishing equipment."

Pee Dee Fire & Safety installs and maintains a variety of customized fire suppression systems, featuring the Amerex KP, the industry standard in reliability and safety.



The Amerex KP Restaurant Systemis a pre-engineered, wet chemical, stored-pressure type with a fixed nozzle agent distribution network. The system agent is Amerex KP liquid fire suppressant, a potassium acetate based solution that suppresses cooking grease fires both through saponification and cooling. The agent has a pH of 9 or less and does not harm stainless steel surfaces.

The Amerex KP is listed by Underwriter’s Laboratories, Inc., ULC and tested to UL Standard 300. The system also conforms to NFPA Standards 17A and 96.

In either automatic or manual actuation, the Amerex KP system works in this manner:

kpdiagram01     1. When a fire starts, the detection network, consisting of fusible links or pneumatic tubing, will automatically detect the fire or the manual pull station can be used, releasing a low pH agent throughout the hood, duct and onto the appliances.
kpdiagram02     2. Either method of actuation will interrupt gas or electrical power to the appliances preceding system discharge, by use of a Mechanical Release Module (MRM). The MRM is a spring-loaded type using a mechanical input and electrical, mechanical or pneumatic outputs, and is capable of actuating from one to ten agent cylinder/valve assemblies.

The combination of the Amerex KP system and an Amerex Model B260 or B262 Wet Chemical extinguisher provides restaurants with a “one-two” attack against the threat of business loss due to cooking operation fires.
