Sirena EX 0100 STL L Explosion-Proof Signal Beacon

Sirena EX 0100 STL L Explosion-Proof Visual Signaling Device (110VAC, 40W)

The Sirena EX 0100 STL L is a heavy duty explosion-proof visual signalling beacon, suitable for use in high-risk industrial, maritime and hazardous situations. This signaling device is designed for use in harsh structural environments and provides different visual signals to signify significant process changes, equipment changes, or hazardous conditions in locations where extremely flammable gas or dust combinations are present. It is based on an EEx de explosion-proof principle of protection combining a flameproof enclosure with an increased-safety terminal compartment separating the possible electrical arcing from the ambient atmosphere. The EX 0100 STL L is a heavy industry infrastructure design, with a 110VAC power supply line, and needs a 40W power envelope.

Key Features

1. Explosion-Proof Dual-Isolation Architecture: Designed according to EEx de IIC T6 classification, utilizing a flameproof chamber paired with an increased safety connection base for maximum ignition deterrence.
2. Corrosion-Proof Marine Construction: Heavy, low-copper aluminum alloy housing finished with a chemical-resistant polyester powder coat paired with a thermal shock-resistant borosilicate glass outer dome.
3. High-Output Visual Dispersion: Standard internal mechanical and physical light pathways ensure omnidirectional illumination output over 360 degrees, breaking through dense ambient industrial airborne debris or sea spray.
4. Severe Environment Ingress Resistance: Sealed completely to a verified IP66 rating, preventing fluid entry under high-pressure spray, heavy seas, and dense particulate accumulation.
5. Continuous Industrial Duty Cycle: Internal electrical ballasts and thermal dissipation pathways are engineered to tolerate uninterrupted continuous duty profiles within hazardous zone thresholds.

Industrial Applications

• Offshore oil exploration rigs, drilling platforms, and production facilities.
• Petrochemical refineries, crude storage terminal manifolds, and gas compression stations.
• Marine vessel engine rooms, liquefied natural gas (LNG) carrier decks, and cargo holds.
• Hazardous dry material handling plants, grain elevators, and pharmaceutical pulverization facilities.
• Wastewater treatment digester areas and chemical processing plants with Zone 1, 2, 21, and 22 designations.

System Compatible

• Control Relay Compatibility: Operates with 110VAC solid state relays, conventional mechanical contactors, or direct digital output modules of leading PLC systems (e.g. Siemens S7-1200/1500, Allen-Bradley ControlLogix, Schneider Modicon) equipped with isolation relays capable of handling inductive and resistive loads up to 40W.
• Cable Gland Hardware Compatibility: Direct structural installation for M25 x 1.5 Ex d or Ex e double-compression brass or stainless steel cable glands for armoured (SWA) or unarmoured marine cables.
• Mounting Integration: Flat surface structural base mounting using typical bolt configurations for bulkheads, structural steel beams or equipment frames.
