Direct Release Low-Pressure Systems

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).

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 agent under pressure, in the cylinder then flows out through the burst point, flooding the agent through the protected enclosure.

Each DLP system consists of a High-Grade Stainless-Steel Direct valve with stainless steel siphon tube, integrated pressure gauge embedded in the valve body for extra protection to monitor cylinder pressure, and a quarter turn isolation valve to interfaces with the AutoFireX Fire Detection Tubing. A PRD (Pressure Relief Device) tested to 44Bar is also provided.

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.
