Technical Overview
The MEDC BG2E is a manual release call point (break glass unit) from the MEDC BG2 range, now manufactured under Eaton’s Crouse-Hinds series following Eaton’s acquisition of MEDC. Per the official Eaton/Crouse-Hinds datasheet (DSMC0006-EN), the BG2 range is certified for use in hazardous areas, with two principal electrical configurations available: an Ex de version rated Ex db eb IIC T6 Gb, suitable for ATEX Category 2GD applications (Zone 1/2), and an Ex ia intrinsically-safe version rated Ex ia IIC T4 Ga, suitable for ATEX Category 1GD applications (Zone 0) — meaning the BG2 range as a whole can be specified across the full spectrum of hazardous area zones from the most demanding Zone 0 down to Zone 2, depending on which configuration is ordered. Both AC and DC electrical versions are available.
The housing is constructed from anti-static, UV-resistant glass-reinforced polyester (GRP) with a red painted finish, giving the unit strong corrosion resistance for offshore platforms as well as onshore oil, gas, and petrochemical installations, while remaining lightweight compared to a metal-bodied alternative. The unit carries an IP66 and IP67 ingress protection rating, and provides contact/switch ratings of 30 Vdc at 5A resistive or 3A inductive, or 250 Vac at 5A resistive or inductive, with six 2.5 mm² field-wiring terminals for connection. Optional configurations include an end-of-line resistor, an in-line resistor, or a combined resistor/diode package, allowing the call point to be integrated into a variety of fire and gas alarm loop monitoring architectures. Operating temperature range is −40°C to +70°C, supporting deployment across the wide ambient temperature swings found in Gulf region outdoor industrial installations.
Applications
The BG2E manual call point is installed as part of fire and gas detection and alarm systems in hazardous industrial environments — offshore oil and gas platforms, onshore process plants, and petrochemical facilities — providing personnel with a manually-operated means to trigger a plant alarm or emergency shutdown sequence directly from the field, wherever a flammable atmosphere may be present.
Why Seven Star LLC
Seven Star LLC supplies genuine MEDC/Eaton Crouse-Hinds BG2 range manual call points to customers across Oman and the GCC, and helps confirm the correct hazardous-area zone rating, electrical configuration, and resistor/diode option for a specific fire and gas system design before order confirmation.
Request a Quote for MANUAL RELEASE’’MEDC’’SERIES:BG2E
Contact Seven Star LLC to request a quotation for the MEDC BG2E manual release call point. Our team can help confirm the correct hazardous-area certification and electrical configuration for your fire and gas system, and support reliable delivery across Oman and the wider GCC region.
Ordering Notes
When requesting a quotation, please specify the hazardous-area zone classification of the installation location (Zone 0, 1, or 2), the required electrical version (AC or DC), and the resistor/diode configuration needed to integrate with your existing fire and gas alarm control panel, so Seven Star LLC can confirm the correct BG2E configuration for your system.
Offshore and Coastal Durability
The BG2E’s GRP housing and IP66/67 ingress protection make it particularly well suited to Oman’s coastal and offshore installations, where salt-laden air and high humidity can accelerate corrosion on metal-bodied alarm devices over time. Seven Star LLC recommends the GRP-bodied BG2 range specifically for offshore platforms and coastal onshore facilities where long-term corrosion resistance is a priority alongside hazardous-area certification.

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.
MEDC products we list
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.
