Cylinder Valve:
GLC Fire Systems offers three sizes of Cylinder Valves: 1 ¼”, 2 ½” and 3”. All valves are made out of brass and come equipped with a permanently tethered Anti-Recoil Plug/Cap to the valve discharge outlet. The Valve Discharge Outlet is available in FNPT for the size 1 ¼” and ANSI groove for sizes 2 ½” and 3”.
Pressure Gauges:
GLC Fire Systems’ Pressure Gauge provides a reading of system pressure at all times. The gauge dial clearly defines normal pressure status, under pressure status, and over pressure status. The Pressure Gauge is built with a two-in-one supervisory switch to monitor system pressure status. The pressure gauge is a UL-recognized component.
Cylinder Straps:
Cylinders with fill capacity of 33, 64, 108, and 230 LBS comes with one 304 Stainless Steel Strap. A Cylinders’ fill capacity of 500 & 810 LBS comes with two 304 Stainless Steel Straps.
Nozzles:
GLC Fire Systems’ Nozzles are made of high grade Aluminum with two discharge orientations: 360° and 180°. The Nozzles discharge ports are pre-drilled to establish a uniform agent distribution inside the hazardous area. Nozzles are available in sizes ½”, ¾”, 1”, 1 ¼”,1 ½”, and 2” and are suited for Upright and Pendent installation. The Nozzles are supplied with NPT threading.
Electrical Actuator:
GLC Fire Systems’ Supervised Electrical Actuator is a Full-Latching actuator that latches upon receipt of a signal from the releasing control panel. The actuator is approved by most UL listed releasing control panels. It requires a supply of 24VDS, 0.5 Amps, and 30 mA for monitoring. The Electrical Actuator is a UL-recognized component.
The actuator comes with a stackable mechanical override for manual operation.
Pneumatic Actuator:
GLC Fire Systems offers pneumatic actuators for slave cylinders’ actuation. The Pneumatic Actuator comes with a nipple, a pilot hose, and tee or an elbow for additional cylinder activation. The Tee, Elbow and Hose are ¼” (6mm) BSPP X NPT.
Pressure Discharge Switch:
GLC Fire Systems Pressure Discharge Switch is Normally Open and will close upon system discharge. It requires a 24 VAC to operate. The switch is a UL-recognized component.
Check Valves:
GLC Fire Systems offers Check Valves for manifold systems and/or main and reserve systems, as per NFPA 2001 standard requirements. The Check Valve must be installed in the vertical orientation with the arrow in the same direction as the flow. Size 1 ¼” Check Valve is made of stainless steel, female thread by female thread. Size 2.5” and 3” Check Valves are made of ductile iron and they are groove by groove.
1.25”
3.5” & 3”Flexible Discharge Hose:
GLC Fire Systems offers a Flexible Discharge Hose for ease of installation and disassembly. The Flexible Discharge Hose is provided with a swivel fitting at the inlet. The 1 ¼” X 16” Flexible Discharge Hose is a twin-steel braided wire, oil resistant, seamless synthetic rubber core hose which meets EN 853-1SN. The Hose is equipped with a female swivel nut at one end and a MNPT at the other end. The 2 ½” and 3” Flexible Discharge Hoses are 304 stainless steel braided hoses with grooved ends which are 42” long.
Liquid Level Indicator:
GLC Fire Systems’ Liquid Level Indicator indicates the level of the liquid in the cylinder, thus enabling the inspector to determine the amount of agent inside the cylinders without the need to disassemble the system for the purpose of weighing the cylinder. This option is available for 230, 500 and 810 lbs filled cylinders.
