Pollution Control Unit Fire Suppression Systems

The CORE fire suppression system is a pre-engineered, pollution control unit fire system that utilizes a water spray system for fast flame knock-down and suppression.

The system is capable of automatic detection and actuation and/or remote manual actuation. The detection portion of the fire suppression system allows for automatic detection by means of an electric thermal detector located in the intake and outlet of the ductwork connection; when the temperature exceeds the rating of the sensor, the regulated release actuates and water is sprayed in the Pollution Control Unit.

A system owner's guide is available containing basic information pertaining to system operation and maintenance. A detailed technical manual is also available including system description, design, installation, recharge and maintenance procedures, plus additional equipment installation and resetting instructions. The system is installed and serviced by authorized distributors that are trained by the manufacturer.

CORE Circuit Board

The CORE Fire System printed circuit board is a microprocessor based control that provides all the necessary monitoring, timing and supervision functions required for the reliable operation of the CORE Protection Fire System. If a fault is detected anywhere in the CORE system, the audible alarm will periodically sound and the “Fire System Activated” light will flash a fault code to indicate the specific fault detected.

 

Electric System with Battery Backup

The detection and pull station for CORE comprise an electric circuit that is connected to a battery backup system. In the event of a power outage, the power to all gas and electric appliances must be disrupted through the use of electric gas valves or shunt trip breakers. The battery powers the detection and pull station circuits, as well as monitoring those devices.

 

Supervised Loop

The quantity of each component will vary based on the system needed for the application. If connecting multiple CORE systems, then see instructions located in operation and maintenance manual.

 

CORE Control Cabinet

The CORE Control Cabinet contains most of the necessary components for the fire system to function. The control cabinet holds the manifold, surfactant tank and pump, CORE control board, power supply and battery backup.

Can the CORE waterline be tied into the building sprinkler system instead of a dedicated water line?

Yes, this is the preferred method as the sprinkler line is typically tied to a supervised valve. It is important to have the pressure reduced to the proper CORE operation pressure of 20 to 70 psi.

 

Is an electric gas valve required with CORE?

Yes, this is an entirely electric system and mechanical valves will not work.

 

When will the battery backup need to be replaced or what maintenance is required for this component?

Every six months, a certified technician should inspect all components of the CORE system to verify proper operation. Every two years, the battery pack in the battery back-up module should be replaced. The replacement battery is hot swappable, which means the battery can be replaced while input power is applied to the unit.

 

At what temperature will the Firestat signal fire condition?

The Fenwal Firestat is used in the duct connection to measure temperature. The standard setting of the Firestat is 360 degrees F; if temperature is higher than the setpoint then the contacts will close on the stat and energize the fire system.

 

How would the fire marshal test CORE onsite?

The fire marshal will verify that the Firestat will activate the fire system. The fire marshal will also verify that the CORE water line is hooked up to a proper source, such as a dedicated line or a fire sprinkler system.

 

What happens if the surfactant is empty?

There will always be at least 1 gallon of surfactant in the tank for a fire situation. The tank has a low level sensor that detects when 1 gallon of surfactant remains in the tank, and saves this for use in a fire.

 

How does the surfactant assist in putting out a fire?

The surfactant raises the pH of water thus acting as a fire suppression agent.

 

Are fusible links used in the Pollution Control Unit with the CORE system?

No, all heat detection is done via the Firestat installed in the Pollution Control Unit.

 

What operating pressure does the CORE system require in order to work correctly?

The CORE Protection should be between 20 and 70 PSI, when in operation, to ensure correct function.

 

What needs to be done when the CORE system needs to be reset?

Multiple methods can be used to reset the fire system. First, the Firestats must be cooled to below its internal set-point. Once these devices have been reset, the timer will automatically stop the fire system once its time duration has ended. An alternative method to bypassing the timer is to press the fire system reset button on the face of the control package. This will de-energize the timer and reset the system. NOTE: The Firestat must be cool for this button to work. After a fire, full inspection by a certified professional must be conducted prior to restarting the fire system.

 

How long does the water spray in the Pollution Control Unit upon the fire system being activated?

The timer included in this package is energized when the fire system is activated, either by a remote CORE Fire Suppression System or by the Firestats. The timer holds the fire system protection on for 30 minutes. If the Firestat is still hot or the pull station is still pulled and this time expires, the timer resets and water continues to spray.
