MEDC SM87LED Ex LED Beacon Range
Overview
The MEDC SM87LED Ex LED beacon range is a high-intensity explosion-proof LED beacon family from the Crouse-Hinds series, certified Ex d IIC T6 Gb for use in Zone 1 and Zone 2 hazardous areas, with weatherproof IP66 and IP67 protection.
Combining long-life LED technology with certified flameproof construction, the SM87LED provides reliable visual alarm signalling in the most demanding offshore, marine, and industrial installations.
Engineering & Design
The beacon is built in either 316L stainless steel or LM25 marine-grade aluminium alloy, both corrosion resistant and lightweight for harsh environments. The glass lens is available in multiple colours with optional lens guards for additional mechanical protection.
Certified to ATEX (Baseefa 03ATEX0222), IECEx, UL, TR CU, INMETRO, and CQST schemes, the SM87LED can be initiated by telephone ringing tone or low-voltage control signals, and SIL 2 certification to IEC 61508 is available on selected versions.

Compatibility & Integration
The SM87LED connects to alarm and fire and gas systems via telephone or low-voltage control signalling, with flameproof cable entries compatible with standard hazardous area glands and junction boxes.
Hazardous Area Support
Seven Star LLC supports complete signalling solutions for classified areas, including beacon selection, cable gland specification, and integration with fire and gas alarm systems for offshore and onshore projects.
Our specialists provide documentation packs and technical advice for Zone 1 and Zone 2 installations across the GCC.
Operational Benefits
Long-life LED technology in the SM87LED reduces lamp replacement frequency in hard-to-reach hazardous area locations, cutting maintenance effort and exposure.
Low power consumption eases load on alarm and fire and gas systems, while the stainless steel option ensures durability in corrosive offshore atmospheres.
Telephone initiation compatibility supports simple integration into legacy tone-based alarm circuits.

Our specialists support hazardous area product selection, cable entry planning, and compliance documentation for your installation.
Selecting the Right SM87LED Variant
Each beacon in the range is defined by its supply voltage, housing material, lens colour, cable entry type and certification. Before ordering from the MEDC SM87LED Ex LED beacon range, confirm the gas group and temperature class required for the installation zone, the supply voltage available from the alarm system, the lens colour defined in the plant alarm philosophy, and the cable gland size. For replacements, read the full part number and certification label on the installed beacon.
- Hazardous area classification of the mounting location
- Supply voltage and initiation method
- Lens colour and whether a lens guard is required
- Number, size and thread type of cable entries
Installation and Commissioning
Installation in a hazardous area must be carried out by competent personnel in line with IEC 60079-14 and the manufacturer instructions. Use certified flameproof cable glands or stopping plugs suitable for the enclosure, close unused entries with certified blanking elements, and keep the flameproof joints clean and undamaged. Mount the beacon where it is clearly visible from the areas it serves. After installation, test the beacon from the alarm system and record the test.
Inspection and Maintenance
Include beacons in periodic Ex inspections. Check the enclosure for corrosion and damage, the lens for cracks or dirt, the gland condition and the cover tightness. Never open the enclosure while energized in a hazardous area unless the site permit allows it. LED beacons need no lamp changes, but a regular functional test confirms the complete alarm circuit.
Use in Oman and the GCC
These beacons are used on oil and gas facilities, offshore installations, tank farms and chemical plants, where high temperatures, sun and salt air demand durable, certified signalling equipment.

MEDC product families on this page
Visual signals include the XB15 xenon beacon, the LD15 LED beacon and the SM87 beacon family with its SM87LED version, for Zone 1 and Zone 2 areas. The DB3 is the alarm sounder. Manual alarm devices are the BG manual call point and a manual release unit from the BG2 call point series, listed as BG2E. The SM87JB junction box completes the field wiring. These devices are ordered with long codes such as SM87BGLAD1T1B1NNRAS or BGEB4B6B1DDCF7R, in which each block of characters selects an option.Where MEDC signaling equipment is used
MEDC beacons and sounders announce fire, gas and process alarms on production platforms, in gas plants, refineries, chemical plants, loading terminals and marine vessels. Call points give personnel a way to raise the alarm by hand, and the same devices are wired into fire and gas panels from many system builders.Ordering MEDC beacons and call points: what we need
The complete order code from the label or the project datasheet is the best starting point. If you are selecting from scratch, send the supply voltage, lens color for beacons, tone and sound level for sounders, enclosure material and finish color, cable entry size and number, the certification required and the ambient temperature. For call points add the switch arrangement, any series or end-of-line resistor values, and label or duty plate text.Browse MEDC products by category: Fire & Gas Systems, Fire & Gas Detector, Automation Accessories.
