Chapter 3: Hazard Analysis

3.1 Introduction

Before any component of the Amerex fire suppression system is installed, including electronics, the hazards to be protected must be identified. These hazards determine where and type of detection that is required along with the type of and quantity of fire suppression agent necessary for protection. When performing a hazard analysis, some helpful tools that can be useful are:

Flashlights – for those hard to see places.

Cameras and note pads – for helping with documenting the construction of the vehicle fire suppression system and creating a bill of materials. Installers must document and retain all system designs.

Temperature measuring devices – Thermocouples work well in helping to identify vehicle operating temperatures. Knowing the vehicle operating temperature details is crucial in selecting appropriate hardware when doing a hazard analysis and system layout.

Access to all Amerex Installation, Operation, & Maintenance Literature – System may require hardware not located in this manual.

NOTE: On all installations, consult the vehicle manufacturer and property owner before making any modifications to equipment.

3.2 Fire Hazard Analysis

A hazard analysis is used as the first step in a process used to assess risk of fire. The result of a hazard analysis is the identification of fire risks. The National Fire Protection Association (NFPA) offers a series of standards with guidelines for a particular product or system being installed. When conducting a hazard analysis, all applicable standards must be observed.

Examples of such standards include, but are limited to: NFPA 17, 17A, 52, 120, and 122.

Below are some additional considerations to be evaluated when doing a hazard analysis.

3.2.1 Identify the Ignition Source(s)

The potential for hot surfaces such as exhaust manifolds, muffler compartments, hydraulic pumps, and turbochargers can be ignition sources. Other hot surface ignition sources can be friction buildup from bearings, brakes, and gears. Electrical shorts from vehicle electronics and batteries can also be ignition sources.

3.2.2 Identify the Fuel Source(s)

Fuels can be found in many different forms including, but not limited to:

Class A Material: wood, paper, coal dust, rags, hoses, tires, combustible refuse buildup.

Class B Material: Flammable and combustible liquids such as gasoline, diesel fuel, cleaning fluids, hydraulic fluids, brake fluids, transmission fluids.

Class C Material: Class C items describe sources of electrical current that can energize an area where a fire is present.

3.2.3 Consulting Vehicle Owner and/or Original Equipment Manufacturer

Previous experience with machinery may indicate where special hazards exist.

Knowing the history about a particular model of vehicle/machine may help with decisions in protection.

3.2.4 Potential Workplace Hazards for the Equipment

Refuse vehicles frequently work in landfills. Some landfills carry substantial class A fuel sources. Machines working in steel refineries can be exposed to external ignition sources. These types of external hazards will have to be considered when determining the right protection required for the particular machine.

3.2.5 Considerations to be Evaluated

Is the hazard in an open area or closed compartment? In an open area, each hazard must be treated as a local application with careful considerations for selecting appropriate detection. Open area hazards can present challenges with heat transfer to the detector if the detector is not properly located for identifying the overheat condition.

Are there many obstructions? Obstructions can limit the exposure of heat to the heat detector. It may be necessary to use additional quantity of heat detection to compensate for obstructions.

How much air flows through the hazard? Airflow can adversely affect of nozzles and dispersion of Dry Chemical Agents. It may be necessary to use additional Nozzles to compensate for air flow.

What are the dimensions of the hazard? Determining hazard dimensions allows for Agent Cylinder size(s) and Nozzle quantities to be calculated.

What is the potential for the hazard to spread to other areas of the vehicle/machine?

Additional protection may be required for those areas as well.

Does the vehicle/machine have additional hand portable extinguishers? Hand portable fire extinguishers are necessary to be used as a backup to an automatic fire suppression system. Appropriate type and rating of hand portable fire extinguishers must be considered.

3.2.6 Selecting the Appropriate Agent

After identifying ignition and fuel sources (see Sections 3.2.1 and 3.2.2), the appropriate fire suppression agent must be selected.

ABC Dry Chemical - Works well on all Class A, B, and C fires. See the latest version of the Dry Chemical System Manual (P/N 13980) located on the Amerex website at www.amerex-fire.com.

Purple K Dry Chemical - Works well on Class B fires. See the latest version of the Dry Chemical System Manual (P/N 13980) located on the Amerex website at www.amerex-fire.com.

ICE Liquid Agent - Works well on Class A and B fires and is good for cooling hot surfaces (turbochargers, exhaust manifolds), but must not be used on electrically energized equipment (batteries, alternators, starters). See the latest version of the ICE System Manual (P/N 22012) located on the Amerex website at www.amerex-fire.com.

3.2.7 Selecting the Appropriate Method of Detection

After identifying vehicle hazard areas, it is necessary to select the appropriate form of detection for those areas. See the applicable electronics manual located on the Amerex website at www.amerex-fire.com.

Spot Heat Detectors (SHD) - Localized area devices that react to “set point” temperatures of 280ºF (138ºC), 350ºF (177ºC) or 450ºF (232ºC).

Linear Heat Detectors (LHD) - Broad area “linear wire” devices of various lengths, that have large surface area for heat detection with a “set point” of 356ºF (180ºC).

3.2.8 Selecting Methods of Actuation

If automatic actuation of any Agent Cylinders in the Amerex Fire Suppression System is selected, a manual means of actuation is also required. At least one manual means of actuation must be located within reach of the vehicle operator during normal vehicle operation. Additional manual means of actuation should be located conveniently in accessible areas along paths of egress. Such manual actuation devices include:

Manual Actuation Button (P/N 14053) - An electronic button located in the drivers area or other locations accessible in the event of a fire.

Manual or Manual/Electric Actuator (P/N 10210 or 23600) - Pneumatic actuation device located in the drivers area or other locations accessible in the event of a fire.

Reference the appropriate Amerex Fire Suppression Installation, Operation and Maintenance Manual.

Chapter 4: System Design, Operation & Installation This Chapter describes design and installation of the Amerex Circuit Monitor and Control Panel system. For mechanical components such as nozzles, agent cylinders and pneumatic actuation devices see Installation, Operation and Maintenance manual 13980.

4.1 Steps to System Design

The appropriate quantity and selection of agent cylinders, nozzles and heat detection devices should be made along with an idea of how the electronic programming should be set up after a hazard analysis has been completed.

The electronic panels must be properly located and installed (See Section 4.2).

The appropriate heat detection devices and manual means of system activation must be located and installed. (See Section 4.3)

Appropriate lengths and selection of wiring harnesses must be made to accommodate the particular style of heat detection device. Appropriate wiring paths must be made from the heat detection device to the electronic panels. (See Section 4.4).

Appropriate lengths and selection of wiring harnesses must be made to accommodate the release zone circuit(s). Appropriate wiring paths must be made from the release zone(s) to the electronic panels. (See Section 4.5).

Any auxiliary input/output devices shall be selected and located/installed. Wiring for such devices must be installed. Proper termination of the wiring harness must be performed (See Section 4.6).

The vehicle power input wiring must be installed. (See Section 4.6).

Once all wiring connections are made, Control Panel testing and programming must be performed (See Section 4.7).

4.2 Electronic Panel Installation

All electronic panels must be mounted in convenient locations permitting periodic maintenance and inspection along with minimal wiring and cable lengths. Proper routing of all wiring and cables to each system component is required and should be considered when choosing an appropriate location. Any obstacles, moving parts, hazard areas, or bulkheads that may inhibit complete connection of all system components or cause damage to components must be avoided. The Circuit Monitor and the Control Panel must be mounted in a location where the audio and visual indicators on the face of the panel may be seen and heard from the operator’s seat. The panel should be mounted in a dry location safe from any potential weather, moisture, and excessive vibration. Consider the most convenient routing path of the mating cables to determine whether a back or bottom connection panel is best.

4.3 Detection Components Installations

Amerex offers several styles of heat detection devices that can be utilized in the Vehicle Fire Suppression System. Among those devices are linear heat detectors and spot heat detectors.

4.3.1 Linear Heat Detector (LHD)

The Linear Heat Detector is a preset 356ºF (180ºC) heat sensing device capable of sensing an overheat condition at any point along its routed path. All LHDs must be installed in accordance with the following instructions:

The LHD must be installed in a hazard area where the potential for fire or overheat conditions exist.

The LHD must be installed in areas where potential damage resulting from normal vehicle operation will not occur. The LHD cannot be chafed, cut, bent or crushed.

The LHD with protective spring (P/N 20083) should be used when extra protection of the LHD is needed.

The LHD wire must not be installed within any hazard area that exceeds 256°F during normal operating conditions. Physical contact with any high heat surfaces exceeding 256°F is not permitted.

Selection of the LHD length should be such that it adequately covers the hazard area but is not excessively long, reducing the potential of damage. The LHD must not interfere with routine vehicle maintenance.

The LHD must be installed in the Class B detection circuit. Multiple LHDs can be connected in series or used in the same circuit, but combined length of all LHDs used in a single circuit must not exceed 100 feet (30.4m).

The cable should be mounted high in the hazard compartment where higher temperatures are prevalent in overheat conditions.

The LHD must not be installed taught without strain relief. The LHD must not be crimped, pinched or bent beyond it’s minimum bend radius of 2 1/2”.

Each LHD must be installed using padded p-clamps (See Figure 4.3.1a) or the p-clamps can be substituted with cable ties and rubber sleeves (See Figure 4.3.1b). If p-clamps are used, LHDs without the stainless steel spring wire (P/N 20075) will use a 3/16” padded p-clamp (P/N 18720), while LHDs with the protective stainless steel spring wire (P/N 20083) will use a 3/8” padded p-clamp (P/N 21806). The LHD must be secured a minimum of every 18 inches.

Use of cable ties and rubber sleeve material is permitted only when using Amerex kits (P/N 23005 or P/N 23006). If using LHDs without the protective spring (P/N 20075), the 3/16” LHD Clamp Kit (P/N 23005) must be used, while LHDs with the protective spring (P/N 20083) will require the 3/8” LHD Clamp Kit (P/N 23006). The LHD must be secured to supporting structure by cinching cable tie over hose, LHD, and structure as shown. The LHD must be secured a minimum of every 18 inches.

4.3.2 Spot Heat Detector (SHD)

The Spot Heat Detector (SHD) is a preset heat sensing device designed to detect heat in localized areas of the hazard compartment. Three SHDs are available with preset temperature set points and mounting styles. All Spot Heat Detectors (SHD) must be installed in accordance with the following instructions:

The SHD must be installed in a hazard area where the potential for fire or overheat conditions exist. Normal ambient operating temperature should be approximately 100ºF below the set point temperature of the SHD used in that hazard area. The wiring portion of the SHD must not exceed 300ºF for extended periods of time.

The SHD can be mounted in any orientation as long as the metallic sensor tip is subjected to the hazard area that is to be protected. Locate the SHD where mud, oil or foreign debris do not interfere with the sensor tip. Locations subject to environmental extremes should also be avoided.

The SHD and its wiring must be installed in a location allowing access for testing and maintenance.

The SHD sensor is vibration resistant. However, do not install the sensor and wiring in locations with different vibration characteristics. For example, the sensor should not be mounted on an engine and the wiring fixed to the chassis unless proper cable routing and support are provided.

Secure the SHD sensor wiring using a padded p-clamp located on or within 4” of each connector (See Figure 4.3.2a).

The bracket style SHDs (P/N 14087/14088) must be mounted using their standard bracket and the appropriate hardware (See Figure 4.3.2a). The bulkhead style SHD (P/N 16615) must be mounted in a bulkhead configuration (See Figure 4.3.2b) by drilling a single 25/32”-7/8” hole through the bulkhead (3/16” MAX thickness) and inserting the SHD. Secure by threading the 1 1/8” jam nut to the threaded portion of the SHD using a medium grade thread locking compound. Tighten to a maximum of 10 inch-lbs.

4.3.3 Manual Actuation Button Installation (P/N 14053)

A fire suppression system is required to have at least one manual means of system actuation or release of the fire extinguishing agent. This manual release must be located within an operator’s reach or along a path of egress. Amerex offers two methods of manual actuation. The first is a manual means of pneumatic actuation using nitrogen cartridges within a pneumatic actuation network. Reference the appropriate Amerex Fire Suppression Installation, Operation and Maintenance Manual (P/N 13980) for installation instructions. The second option is a Manual Actuation Button as part of the Fire Suppression System. This button is a normally open switch that closes when the red “FIRE” button is pressed. The button is installed in the Class B detection circuit and can be flush mounted by drilling a single 1 1/2”-1 5/8” hole through a surface (7/16” MAX thickness) and inserting the Button (See Figure 4.3.3a). Attach using appropriate hardware. The button can also be surface mounted (See Figure 4.3.3b) using appropriate hardware. Use the dimensions shown in Figure 2.6.

4.3.4 100 PSI Pressure Switch (P/N 22574/22573)

The 100 PSI Pressure Switch is a normally open used to indicate that a system actuation has occurred by means of manual actuation via the pneumatic actuation network. Reference the appropriate Amerex Fire Suppression Installation, Operation and Maintenance Manual for 100 PSI Pressure Switch and pneumatic actuation network installation instructions. The switch is connected to the Class B detection circuit of the system.

4.4 Detection Circuits

Detection: The Circuit Monitor and Control Panel can operate up to two detection zones and one releasing zone. The choices for detection are spot heat detectors, line-ar heat detectors, remote manual actuation buttons. The 100 PSI Switch can also be connected in the detection circuit to signal the panel of a pneumatic manual actuation, but does not act as a heat detection device. These Class B devices can be used in any combination by connecting in series. An End of Line Module (EOL) is always re-quired at the end of the Class B circuit. All detection cables and components are color coded green.

4.6 Input/Output Devices

4.6.1 Vehicle Power Input

The Power Connection Lead, see Figure 4.4b, is used to bring power from the vehicle battery (12 or 24vdc) to the panel. It is supplied with a fuse holder and a 10 Amp fuse to protect the panel and associated circuits. The power lead is connected to the red color coded connector of the panel leads.

WARNING: USE OF THE AMEREX SUPPLIED POWER LEAD IS CRITICAL TO

PROPER FUNCTIONING AND PROTECTION OF ALL SYSTEMS ELECTRICAL

COMPONENTS. USE OF POWER SUPPPLY LEADS OTHER THAN THE TYPE

AND RATING SPECIFIED IN THIS AND ALL OTHER ASSOCIATED MANUALS

WILL VOID FACTORY MUTUAL APPROVALS AND VOID THE AMEREX

WARRANTY.

WARNING: AT NO TIME SHOULD THE BACK-UP BATTERY BE USED AS THE

MAIN POWER SOURCE. THE SYSTEM MUST BE CONNECTED DIRECTLY TO

THE VEHICLE BATTERY AS A MAIN POWER SOURCE.

4.6.2 Agent Cylinder Pressure Switch Input

The Control Panels (P/N 17310 and 17311) include two connection leads for the wiring of a pressure switch (or switches in the case of multiple agent cylinders). Pressure inside the agent cylinder holds electrical contacts normally closed. Loss of agent cylinder pressure will result in a “Service System” LED flash seven times at the control panel and the audible alarm will pulse, on systems so equipped. The Agent Cylinder Pressure Switch Leads are two blue color coded single conductor leads terminated with single conductor male and female plugs. These plugs are connected as supplied. To connect the agent cylinder pressure switch leads, unplug these leads from each other and attaché the two male and female leads from the pressure switches. If no pressure switch is used, the pressure switch leads from the panel must be plugged together to get the green System OK LED.

4.6.3 Output Fire Signal Connections

The Control Panels (P/N 17310 and 17311) include a connection lead for engine shutdown equipment or auxiliary safety equipment such as air dampers, warning horns or lights, See Figure 4.6.2. The relay circuit provides a normally open and normally closed contact to allow wiring for “energized to run” or “energized to stop” configurations. It is the responsibility of the installer to gain sufficient understanding of vehicle operation to determine:

If the device or equipment is “energized to run” or “energized to stop” (Power supplied to terminate normal operations). The relay is rated for maximum of 5 Amps and can be used with either 12 VDC or 24 VDC systems. If the relay is connected to a vehicle multiplex system or shutdown device the device program allows a delay or logic algorithm for mechanical bounce of 30 milliseconds.

WARNING: THE RELAY CONTACTS ARE RATED FOR A MAXIMUM OF 5 AMPS.

THIS VALUE MUST NOT BE EXCEEDED.

Any device that is wired to the relay contacts must draw its own current from an independent power lead fused with a 5 Amp type AGC fast blow fuse. In addition, the internal relay “common” contact is also protected with an internal self- resetting circuit breaker.

The color code for the relay wiring is as follows:

Common – Red

Normally Closed – Black

Normally Open – White

Use Amerex Hazard Wire or other insulated wire of AWG 18 or equivalent for connection purposes.

Two examples of relay usage are shown IN Figure 4.6.3a and 4.6.3b. They are for reference only. Before connecting the relay it is advisable to consult the vehicle manufacturer for proper engine shutdown methods. Not all vehicle electrical systems are the same, and improper shutdown procedures can damage certain vehicle components.
