The typical PCU includes a washable steel pre-filter and disposable, high efficiency (MERV 14) media filter. An additional high efficiency (MERV 14) is available for smoke control and odor control is handled via an optional module (typically 50/50 blend carbon/permanganate). Sizes range in capacity up to 10,000 CFM. The PCU is ETL listed and is suitable for indoor or outdoor installations.

The Advanced Filter Monitoring includes a module that provides the necessary precision pressure measurements for accurate monitoring of the complete system. Based on the measurements, the module will then initiate actions via the electric control package and give readings to the user. Direct access to the operating conditions are provided through the use of an HMI (human machine interface), which is conveniently located on the PCU.

- Sustainability – Sustainability - Extends life of various filters, addresses specific filters which need replacement based on monitoring
- Ease of Installation and Startup – automatic calibration of the system via HMI
- Maintenance – Provides advanced notice, pinpoints specific faults to address
- Reliability – Ensures proper operaion of the PCU
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. If the Pollution Control Unit Firestat senses a temperature hotter than its internal setpoint, an electric signal is sent to the CORE Fire System Cabinet. An electric water solenoid is energized allowing the flow of water to the Pollution Control Unit mounted manifold.
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.
A system owner's guide is available containing basic information pertaining to system operation and maintenance. The system is installed and serviced by authorized distributors that are trained by the manufacturer.

Overview of all the pieces and parts that make up the CORE Fire Protection System.
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 supervised loop is a class A fire loop, it is the means by which fire sensors and pull stations are connected to the CORE system. It incorporates both redundancy and fault detection.
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.
