Indirect Release Low-Pressure Systems

PRODUCT OVERVIEW & PRINCIPLE OF OPERATION

AutoFireX ILP- Indirect Release Low-Pressure 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 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 ILP 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 due to loss of pressure in the tube connected to the valve, the pressure from the top assembly of the ILP valve is released (can be done by both automatic or manual activation) thereby the internal piston slides to its fully open position, allowing the pressurised agent to travel through any or combination of four outlet ports via delivery hose/pipes and discharge out from the fixed nozzles, within the protected area, flooding the entire area with the agent and suppressing the fire instantly.

Each ILP system consists of a High-Grade Stainless-Steel Indirect valve with three standard detection 1/8” ports (SV,P/s or P/g etc.), and four 3/8” discharge ports, SS siphon tube, integrated pressure gauge embedded in the valve body for extra protection to monitor cylinder pressure, and a quarter turn isolation valve with provision to interface 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 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.
