Utilizing the industry recognized FM-200 suppression agent, Amerex has developed an affordable pre-engineered clean agent fi re suppression system to protect areas with sensitive electrical equipment and valuable data. As an industryleader in innovative design of products that provide the quality and performance you expect, Amerex has developed the CPS system to be the most cost effi cient clean agent system available. The modular design incorporates pre-assembled wiring harnesses and keyed locking connectors on all electrical components to assist you in a simple and confi dent installation. Agent tanks are available in two sizes having a diameter of ten inches making tank location in confi ned spaces less stressful. Tanks are charged with FM-200 in increments of two pounds in a small tank or three pounds in a larger tank for a custom installation without un-necessary expense. Electrical actuators are used for system actuation and can be reset reducing the number of components to be replaced during service after discharge. The CPS system is designed to use schedule 40 pipe giving you easy access to the materials you need to complete the installation. Nozzles are available in three designs; corner, side wall, and center room for fl exibilty in system installation to protect those “challenging” areas. The Amerex CPS is monitored by an electrical control panel that has a battery back-up for 24 hour protection during power failure. Photoelectric smoke detectors are used for detection and are cross zoned to reduce the potential for unwanted system discharge. A bell and horn – strobe device alarm when fi re conditions are present. All electrical circuits are supervised and factory terminated.

Agent:
The extinguishing agent used in the Amerex CPS is FM-200 manufactured by Great Lakes Chemical, A Chemtura Company. The chemical name for the agent is Heptafl uoropropane (CF3CHFCF3), identifi ed in NFPA 2001 as HFC-227ea. This agent was developed as an environmentally safe alternative to Halon 1301 and is intended to prevent business interruption due to the risks of fi re and to prevent the loss of irreplaceable, high value assets from fi re.
HFC-227ea is on the U. S. Environmental Protection Agency’s (EPA) Signifi cant New Alternatives Policy (SNAP) Program list as acceptable for use in occupied spaces. HFC-227ea is included in NFPA 2001, Standard on Clean Agent Fires Extinguishing Systems with exposure limits of 5 minutes for design concentrations up to 10.5%. The primary extinguishing mechanism of HFC-227ea is heat absorption. It absorbs heat at the molecular level faster than the amount of heat generated by the combustion reaction and essentially ceases the combustion reaction since it cannot sustain itself. Although the physical mechanism of heat removal is the predominant mechanism of fl ame extinguishment, there is a chemical contribution to fl ame extinguishment which arises from the thermal decomposition of small amounts of HFC-227ea in the fl ame.
For an automatically operated fi re suppression system protecting Class A hazards a minimum design concentration of 7.0% by volume is recommended. For systems protecting Class A hazards that are manually operated a minimum design concentration of 7.6% by volume is required. Typically, Class B hazards have higher extinguishing concentrations and all Class B systems are designed with a 30% safety factor.
Agent Tanks:
Available in two sizes, each having a diameter of ten inches. Tanks are charged with FM200™ in increments of two pounds in a small tank or three pounds in the larger tank. The tanks are pressurized to 360 psi @ 70°F and available in agent weights of 16 to 44 lbs. or 46 to 130 lbs. respectively. Agent tanks are constructed of low carbon steel and have an epoxy primer and polyurethane paint finish. Discharge valve assembly consists of brass and stainless steel components with rubber seals. Mechanical and Electrical actuators for system discharge. Up to 5 additional agents tanks can be actuated using pneumatic actuators for a total of 6 simultaneously discharged tanks. Each agent tank includes a factory installed low pressure switch to monitor the tanks condition and signal the releasing panel if pressure drops below 285 psi. A unique dual-outlet valve provides capability to protect two rooms of different sizes, or a room and under floor with one tank.
Electric Releasing Control Panel:
Provides supervised circuit monitoring and contains a back-up battery providing 24 hour protection during power failure.
Detection / Manual Actuation:
Photoelectric smoke detectors are cross zoned to reduce potentially unwanted discharge. Detectors are provided with keyed locking connectors. Wiring harnesses are factory assembled in pre-determined lengths and are equipped with matching keyed locking connectors. The manual pull stations, used to release the system, are double action. A combination pull station/abort is available that includes an abort switch.
Alarming Device:
A bell and horn/strobe design give both audible and visual indication that fi re conditions are present. An alarm bell rings when smoke is detected and the horn/strobe operates to signal the start of the release time delay.
System Components
Cable
Cable assemblies used on all circuits except the release circuit are 4-conductor plenum rated cable type CMP complying with NFPA 70 (National Electrical Code) Article 760 for use on power limited fi re alarm circuits. Each of the four conductors is stranded 18 AWG copper with extruded insulation. An aluminum shield covers the 4 conductors with a white mylar outer jacket. The release circuit is non-power limited and the cable assembly is type NPLF complying with NFPA 70 (National Electrical Code) Article 760 for use on non-power limited fi re alarm circuits. This 2-conductor cable assembly is rated for 600 volts. Each conductor is stranded 18 AWG copper with fl ame retardant PVC insulation and an aluminum/ polyester shield covers the pair. The outer jacket is black, flame retardant, low temperature with a temperature rating of 90°C. Single four conductor cable assemblies and single two conductor release cable assemblies can be pulled through ½” conduit feeding/pulling the receptacle end through, multiple cable assemblies run in conduit should use ¾” or larger conduit. Since the release circuit is non-power limited the release circuit cable must run in its own conduit or raceway. Each device and each cable assembly include four position, keyed, locking connectors. The connectors are Molex® brand Mini-Fit Jr. ® model. The plug and receptacle housings have a UL fl ammability rating of 94V-0. The terminals are gold plated to reduce oxidation contamination and provide good electrical connections for the low voltage and low current circuits of the releasing panel.
Discharge Pressure Switch:
The discharge pressure switch is used to send a signal to the releasing panel when the valve has been opened. In addition to sending a positive signal of automatic actuation it also serves as an initiating device sending a signal to secure the protected room if the valve has been operated manually by the manual local actuator. Amerex provides this discharge pressure switch with a pre-installed wire harness for connection to the panel using a junction box harness and cable assemblies.
Nozzles:
Brass discharge nozzles are available in three confi gurations; a 90° 1-orifi ce nozzle for corner of room locations, a 180° two orifi ce nozzle for side wall locations, and a 360° four orifi ce nozzle for center of room locations. Two and four orifi ce nozzles have their orifi ces on 90 degree centers.
