DLP Clean Agent

PRODUCT OVERVIEW& PRINCIPLE OF OPERATION

AutoFireX DLP- Direct Release Low-Pressure Clean Agent Systems are primarily a Pre-Engineered Automatic Fire detection and suppression System utilising various Low-pressure agents like, Clean agents (HFC227ea, FK 5-1-12, FE36) Dry Chemical Powders etc. These Units are designed, manufactured, and tested in ISO 9001:2015 certified facilities

The AutoFireX Linear Pneumatic Fire Detection Tubing (LP-FDT) is installed and connected to DLP Valve and routed throughout the protected hazard area/enclosure. Being heat sensitive, the primary function of Linear Pneumatic Fire Detection Tube (under pressure) is to detect heat/fire and activate the valve for discharge of the agent by rupturing at the hottest point along its installed length on flame impingement. On rupture a nozzle is formed at the burst point.

The clean agent under pressure, in the cylinder then flows out through the burst point, distributing the clean agent through the protected enclosure

Each DLP system consists of (but not limited to) a High-GradeStainless-Steel Direct valve with straight siphon tube, integrated pressure gauge embedded in the valve body for extra protection to monitor cylinder pressure, and a quarter turn ball valve to interfaces with the AutoFireX Fire Detection Tubing. A PRD (Pressure Relief Device) tested to 44Bar is also provided. The systems is supplied complete with CE Cylinders and Brackets with appropriate agents, as required.

To assist in annunciation, an optional pressure switch provided, can be installed at one of the ports on valve or at the end of the detection line using a End of Line Adaptor, also available with the system. The pressure switch provides a potential free contact, that can be interfaced, with existing FACP (Fire Alarm Control Panel) to indicate system discharge, shutdown ventilation, shut-off electrical power, as may be required. Alternatively, it can also be connected to a Audio Visual (A/V) alarm unit for annunciation.

GENERAL SPECIFICATION

*Figures based on ideal conditions in fully enclosed space. Actual figures may vary according to application.

Maximum volume coverage is determined by agent concentration discharged within the enclosure where the fire hazard is located. The discharge time for DLP system utilising various agents differ from agent to agent and capacity of the cylinder.

SUPPRESSION AGENT

AutoFireX Automatic Linear Pneumatic DLP – Direct release Low Pressure fire suppression units are designed to be used with Clean Agent FK5-1-12 (Fluro Ketone-generic name), Chemical formula -CF3CF2C(O) CF(CF3)2, which is more popularly recognised as Novec 1230 (Brand) manufactured by another reputed manufacturer. This Fluid has been evaluated and approved for use in unoccupied areas as a Total Flooding agent in NFPA 2001. This agent is a colourless,low odour fluid under room temperature condition. It is tested for being nontoxic under storage condition, electrically nonconductive, leaves no residue, environmentally friendly- Zero Ozone depleting potential & GWP of 1, and is an extremely effective fire suppression agent.

USAGE

Clean Agent FK5-1-12 Fire Protection Fluid is stored and transported as liquid under normal temperature and is discharged as gaseous fire suppression agent that is effective for use on:

• Class A – Surface type fires
• Class B – Flammable liquid fires
• Class C – Electrical fires

TYPICAL OPERATING AND ENVIRONMENTAL LIMITATIONS

DESIGN & ENGINEERING CONSIDERATIONS

AutoFireX DLP systems arebased on Pre-Engineered design concept that minimizes the amount of engineering involved in system design. The DIOM – Design Installation, Operating & Maintenance Manual clearly specifies the limitations and capabilities of the system. All such systems including the AutoFireX FDT detection/discharge tubing when installed within the limitations stated in the manual, no hydraulic calculations are required to determine pressure drop, agent flow, or discharge time.
