MEDC BG Manual Call Point – BGEB4B6B1DDCF7R (Ex de, ATEX)
Overview
The MEDC BG manual call point with part number BGEB4B6B1DDCF7R is an explosion-proof manual alarm call point from the MEDC BG range manufactured under the Eaton Crouse-Hinds brand. The part number decodes as a BG call point with ATEX/CENELEC Ex de certification, two M20 entries, a glass label, DC operation, a double changeover switch, a resistor series option, earth continuity and seven standard terminals in a red finish. It is designed for manual fire and process alarm initiation in hazardous locations.
Engineering and Design
Each digit of the BGEB4B6B1DDCF7R code maps to a build option: BGE identifies the Ex de model family, EB gives ATEX/CENELEC Ex de certification, 4B6B specifies two M20 cable entries with position codes, 1 selects the standard glass label, D indicates DC operation, the second D specifies a double changeover switch, C adds a resistor series option, F provides earth continuity, 7 gives the standard 7 x 2.5 mm terminal arrangement and R is the red finish. The switch is rated up to 30 Vdc at 5 A resistive or 3 A inductive, with a temperature range of -40 to +70 deg C for the BGE model.
The call point is connected into the alarm loop through the two M20 entries, and the double changeover switch provides both NO and NC contact sets so the loop can be supervised against open circuit and short circuit faults. The resistor series option installs a fixed resistor across the call point terminals, which lets the fire alarm panel distinguish a normal loop from an activated call point during line monitoring. Wiring is terminated on the seven standard 2.5 mm terminals and the glass label is replaced after each operation, with spares held at the panel location.
Key Features
- ATEX/CENELEC Ex de certified manual call point
- Two M20 cable entries with position coding
- Double changeover switch rated 30 Vdc 5 A resistive
- Glass break label with red finish
- Resistor series option and earth continuity fitted
- Seven terminals, 7 x 2.5 mm standard
- Operating temperature -40 to +70 deg C
Applications
The MEDC BG manual call point BGEB4B6B1DDCF7R is installed in fire and gas alarm systems in refineries, terminals, offshore platforms, chemical plants and marine vessels where Ex d/e protection is required. The call point connects directly into the alarm loop and is operated by breaking the glass, providing a positive manual alarm input alongside automatic detectors. Gulf projects specify the BG range for hazardous-area escape and alarm systems.
In hazardous-area fire and gas systems the BG call point is mounted on escape routes, at doorways and near process areas, alongside the MEDC sounders and beacons of the same alarm zone. The Ex de certification covers both the switching chamber and the termination compartment, so the loop wiring enters through the certified glands without additional protection. Sites in the Gulf commonly standardise on the BGE model with DC operation and the resistor option for supervised loops, keeping the part number history with the fire alarm system documentation.
Spare planning for the BG range covers the replacement glass labels and the fixing spare kit, because the label is broken at each operation and is restored by the maintenance crew. The switching chamber is opened only with the loop isolated, following the installation instructions of the manufacturer.

Why Seven Star LLC
Seven Star LLC supplies MEDC BG manual call points and alarm components for hazardous-area fire and gas systems in the GCC. We decode the full part number, confirm the Ex marking and check the switch and terminal configuration against your loop design before your order is confirmed.
Technical Specifications
The MEDC (Eaton/Crouse-Hinds Series) BG-range manual call point is an Ex de (flameproof) break-glass alarm activation unit built for hazardous-area fire and emergency alarm systems. The enclosure is glass-reinforced polyester, anti-static and UV-resistant, rated IP66/IP67, with an operating temperature range of -40°C to +70°C. Activation is via a membrane-protected break-glass element that does not require a separate hammer, and contacts are rated 250V AC at 5A (resistive/inductive) or 30V DC at 5A (resistive). Standard fixing centers are approximately 92×72 mm, and the standard finish is red.
Certifications
The BG range holds ATEX Ex de certification (certificate BAS02ATEX2105X) and IECEx Ex de certification (IECEx BAS 18.0100X), covering deployment in Zone 1 and Zone 2 hazardous areas across international projects without needing separate region-specific approvals. The exact order code (as with BGEB4B6B1DDCF7R) encodes specific configuration options — color, glass type, and contact arrangement — within Eaton’s official BG ordering system, so Seven Star LLC confirms the full code against the customer’s exact requirement before quoting.
Applications
BG manual call points are installed at fixed, accessible locations throughout hazardous-area industrial sites — offshore platforms, refineries, gas processing plants, and other Zone 1/2 classified facilities — to give personnel a manual means of triggering the site fire or emergency alarm system in addition to automatic detection, as required by most process-safety fire strategy documents.
