Kitchen Protection Systems

Workplace accidents are most commonly reported in kitchens—a fact frequently emphasized by health and safety experts during office training sessions. If the kettle poses a significant risk that is constantly highlighted, one can only imagine the greater dangers present in a kitchen environment where open flames are regularly used.

At Ugasimy, we have recognized this challenge, which is why our Design Office is dedicated to providing comprehensive fire protection solutions for restaurant kitchens. Our goal is to ensure the safety of both employees and guests while minimizing the risk of damage to equipment.

Our custom-designed fire protection systems utilize products from the Amerex brand and are built around three key modules: mechanical, pneumatic, and electronic. Together, these components deliver exceptional protection across all risk areas within the designated zone. Additionally, the working gas employed in our system is environmentally safe nitrogen.

The Mechanical Release Module (MRM) is the heart of the Amerex Kitchen Fire Suppression System. The MRM features a spring-loaded design, using a mechanical input and electrical, mechanical, or pneumatic outputs. Specifically, the MRM assembly connects and controls the actuation cartridge, detection components, manual pull station(s), gas valve, snap-action switches, and agent cylinder discharge valve(s).

The Amerex KP MRM is capable of actuating from one to ten agent cylinder/valve assemblies using one nitrogen cylinder. The MRM has two snap-action switches – one for electrical signaling, power shutdown, and other auxiliary functions, and a second alarminitiating snap-action switch for connection to a fire alarm panel. It comes pre-installed in its own stainless-steel enclosure. This enclosure displays a system status indicator and a window to observe the nitrogen cylinder pressure.

The MRM can be used with appliance-specific or zone defense coverage.

The Pneumatic Release Module (PRM) is a mechanical releasing control unit that offers superior detection by using a continuous linear pneumatic detection system instead of intermittent fusible link detectors. When the PRM detection line is exposed to a fire condition, the tubing ruptures, relieving all pressure in the tubing and accumulator, thus firing the system using a nitrogen cylinder. Some benefits of using the Amerex PRM in your Kitchen Fire Suppression System include no detection cable, no crimps, and no conduit or corner pulleys required in the detection line.

The PRM control mechanism interfaces with manual pull station(s), actuation networks, mechanical gas valves, and also offers electrical contacts for shutdown functions. The PRM can fire up to 10 agent cylinders and actuate up to two gas valves. The PRM comes complete with enclosure, accumulator, end of line fitting, and connector for up to two remote mechanical manual pull stations, two snap-action switches, and enclosure “knock-outs” for applicable connections.

The PRM can be used with appliance-specific or Zone Defense Coverage.

The Amerex Strike Control Unit is the result of years of rugged mining, transit and military electronic evolution. Specifically designed to work with the Amerex Kitchen Fire Suppression System, the Strike Control Unit is able to monitor and release two completely separate hood systems, and it can be tied into auxiliary controls such as the building’s alarm system. Primary and secondary batteries provide continuous, uninterrupted fire detection and fire suppression system actuation without the need for an external power supply. Unlike traditional control mechanisms, the Strike Control Unit utilizes Linear Heat Detectors and Spot Heat Detectors that have no moving parts are fully supervised, minimizing the negative effects of grease build-up.

The Amerex Strike Control panel works with both appliance-specific or zone defense coverage and provides 24/7/365 coverage. It interfaces to Amerex UL-listed gas valve and multi-relay high-current auxiliary switching modules and features event logging and recording. Easy to install, the Strike Control Panel comes inside a stainless steel case.

The Helix Fire Suppression System is a unique pre-engineered system designed to utilize electric detection and actuation interfaced with the Strike Electronic Control System (ECS). The Strike ECS fully supervises all system circuits, ensuring functionality, which includes constant monitoring of agent cylinder pressure. Because PCU fires require quick response, the Helix system’s detection network is designed using continuous linear heat detection.

The Helix system’s configuration also minimizes nozzles, which effectively reduces the number of agent cylinders and distribution network components, making Helix cost effective without compromising performance. The Helix agent distribution network is easy to install outside the cramped interior space of a PCU, using cutto-length hydraulic hose. This PCU system operates either automatically if actuated by a detector or manually if actuated by a pull station.
