2.3. Additional Information

At KFT we use a modular design and construction methodology. This allows for some modification to the final position of features during the design review phase with the Owner.

This methodology also allows for adaptation and modification in the future. Should training needs change or grow, the KFT units are readily adaptable to suit such requirements.

When evaluating the fire training simulation equipment, we encourage you to fully review the type, quantity and quality of equipment that we have offered. As a company committed to the provision of only the highest quality equipment, we confirm that our offer is fully compliant with the latest codes and regulations. Failure to comply with the regulations will result in an unsafe installation that may result in failure and injury.

Not all simulators are the same. KFT quality and level of experience illustrates a full mission achieving solution, particularly related to the provision of field proven equipment.

2.3.1. Technical Rooms

The technical rooms will be used to house the KFT process control equipment. It is a safe area where the process equipment is protected from the live fire training environment and does not take up valuable training space of the users. KFT will populate the technical areas with the control equipment to support the KFT supplied equipment as listed in Table 1.

2.3.2. Smoke Machines

To enhance the training environment KFT Fire Trainer will integrate smoke machines into the Fire Training System.

All trainers will include a smoke generation system that provides simulated smoke obscuration into and throughout the burn room. The trainer control system controls the smoke emission. The smoke will create obscuration of less than one-foot visibility at the three foot level within the burn room while the flames are active. This smoke is non-toxic, safe for use with open flame, and safe at the operating temperatures readily found within the burn room.

a) Each fire trainer will include an integral smoke generation system that produces realistic smoke effects for the burn room and floor containing the operated trainer using hypoallergenic theatrical smoke fluid.

b) Each smoke generation system will include a fluid reservoir and distribution center capable of delivering artificial smoke as required.

c) Each smoke generation system will be programmable with an operator controlled variable discharge. Each system will provide the operator the ability to vary discharge duration and intervals between cycles from the main control touch panel without the use of any external equipment.

d) Each smoke generation system will provide low visibility training environments during fire conditions. The smoke generation system meets all applicable codes and standards and is suitable for the application. Smoke fluid is non-combustible, non-toxic, and safe for use for personnel, the training building, and the equipment. There will be no environmental impact caused using the smoke generation system.

e) The smoke generation system has the ability to totally fill the entire burn room of the operated fire trainer.

f) All components of the smoke generation system have been designed and fabricated to meet the conditions of the training building and burn room environment.

g) The reservoir for the smoke solution is easily accessed for filling and designed to minimize the risk of contaminating the control cabinet and controls should the reservoir leak or become overfilled.

h) The reservoir for the smoke solution is fully removable from the control cabinet.

i) The smoke solution is protected from freezing under harsh weather conditions

j) The smoke generation system has been designed and fabricated to work with the fire training control system, including the following:

i) Respond to pre-programmed commands from the fire training control system to produce smoke before and during operation of the trainers.

ii) Respond to manual command for smoke during non-fire trainer use (search and rescue training and similar scenarios).

iii) Respond to manual commands to produce additional smoke before and during fire training scenarios.

iv) Shut down smoke generation upon automatic commands from the control system and upon manual command.

k) Additional, optional smoke machines (if requested) for rooms that do not have trainers can be connected to the trainer controls, so that all rooms in the burn building can be filled with smoke.

2.3.3. Safety Systems

In accordance with NFPA 1402 (2019) KFT will provide regulatory compliant Safety Systems for the Live Fire Training Areas, including Gas Detection, Temperature Monitoring, E-Stops and Extract ventilation. These systems will be described fully in the Control System description in Section 4.

3. Fire Scenarios

The proposed fire scenarios will be a series of LPG vapor fuelled Fires. The Fire Training scenarios will be designed to represent the chosen fire type and will be fabricated to the highest quality and latest standards.

Table 1 lists the proposed scenarios.

Each fire generation area or fireplace operates on the same principle. A fuel source is ignited by an ignition source to produce a pilot flame and when the pilot flame is confirmed by the operator, a main flame is ignited from the pilot flame. KFT provides dedicated combustion air to the Mock-up area to ensure effective combustion of the LPG propane is achieved in a safe manner.

The control of the fuel for the pilot and the main flame is from the HMI (Human Machine Interface) control screen and the wireless controls.

The LPG Vapor main flames are ignited from the electronic pilot burner ignition.

The failure of the pilot flame to light or failing during operation will automatically inhibit the operation of the fire scenario. This is a critical safety feature and is required by regulation when igniting LPG Fire Scenarios. This will be communicated to the operator via the HMI.

All flame producing components are located within the fire prop structure to produce flame growth in and around the fire prop structure consistent with the represented fire.

All trainer fire props and mock-ups are fully integrated with all burners and pilot systems built in.

All fires are generated from multiple similarly configured modular hardware sets Training fires and effect fires will be instructor controlled. The control system, however, will automatically monitor all trainer safety systems and shall stop all training fires and begin building ventilation as appropriate for the specific safety system alarm or malfunction.

A wireless handheld control unit shall be used to control the training fire with a minimum of three height settings (low, medium, and high). Continuous and full range control over fire heights is available.

For flashover/rollover effects, an on/off control will be provided Control racks are capable of being remotely located above, below, or to the side of the multiple burn rooms controlled from each control module No fire burn room will be supplied without being a fully independent, dedicated pilot burner. This includes all extension fires and flashovers.

Flashover fires will not require any extension burners in order for the flames to extend across the ceiling. Flashover fire generation systems are compliant with NFPA 1402.

The fire scenarios listed in Table 1 will be provided as per the specification.

Trainers are capable of being "computer run", including agent detection and programmable training scenarios run by the computer, in addition to "instructor run", with an instructor running all scenarios with manual controls.

3.1. Internal Fire Scenarios

The internal fire scenarios will be a series of LPG Propane Fuelled Fire Scenarios. The Fire Training scenarios will be designed to represent the chosen fire type and will be fabricated to the highest quality and latest standards.

Please note alternate Fire Scenario Options are available from our extensive library of solutions. If you require either an alternate or additional fire please advise. These may be available at no extra cost depending on the fire type, quantity and location.

4. Control System

KFT proposes to supply you with a state-of-the-art control system to control the Fire Scenarios. The following sections describe the control components behind the control system and the features it offers. It is a proven control system that offers you a reliable and repeatable LPG Propane fuelled fire scenarios with several important safety features. The system should be enabled prior to use via a security key. In addition to this, the control system also comprises a local control feature where a wireless controller can locally control features of the training area.

The system has been used successfully and with complete safety in both Fire Training Buildings, Aircraft and Maritime Simulators throughout the world without a single safety incident. Per specification the system can be operated in Manual mode.

Per the request of the Mississippi Fire Academy Leadership Team, a bypass feature will be provided which allows the training cadre to select changes to the standard KFT provided controls. Specifically, the academy would like to raise the high temperature emergency stop setting from the current 500 degrees Fahrenheit to the previous standard of 700 degrees.

Additionally, the academy would like to enable all fire controls from the central control room rather than a local wireless pendant with each fire training instructor. KFT will provide a training system that is compliant with the 2019 edition of NFPA 1402, if the Academy leadership selects to raise the temperature setting to 700 degrees or control all fires from the central control room vs a pendant that is local to the individual burn room, this will be accomplished with either a password protected or physical key switch to change the setting above. Additionally, the switch will require acknowledging that the NFPA 1402 standards are being bypassed.
