Product Introduction & Supply Chain Strategy
The MEDC BG2EDC1FR is an explosion-proof, heavy-duty manual call point designed for harsh industrial environments, offshore platforms, chemical plants, and marine installations. Housed in a corrosion-resistant, glass-reinforced polyester (GRP) enclosure with Ex d flameproof protection, this break-glass alarm station allows personnel to manually trigger fire alarms or emergency process shutdowns (ESD) safely in Zone 1, Zone 2, Zone 21, and Zone 22 hazardous areas.
This product is a Brand New Surplus unit. It is not used, not pulled from a decommissioned facility, and not refurbished. Life-safety equipment in hazardous locations allows zero margin for error. Refurbished call points often suffer from degraded environmental seals, micro-cracks in GRP housings from previous UV exposure, or arc-pitted switch contacts. A failure of a manual alarm station during an emergency can endanger life, cause severe regulatory fines, and result in catastrophic facility losses. Purchasing New Surplus guarantees 100% mechanical integrity, compliance with strict ATEX/IECEx standards, an operational lifespan of 10 to 15 years, and complete operational readiness.

Installation & Configuration Guide
1.Pre-Installation Setup and Safety:Area Safety & LOTO.
Verify the target installation zone is gas-free or perform hot-work permit validation. Isolate incoming signal and power lines using Lock-Out/Tag-Out (LOTO). Put on a grounded anti-static wrist strap before opening the enclosure cover.
2.Removing the Legacy Call Point:Label Wires & Extract Unit.
Unbolt the front cover screws to open the enclosure. Tag all loop wiring connected to the internal switch terminals and end-of-line (EOL) resistors. Disconnect the wiring, loosen the cable glands, and unbolt the chassis from the wall or mounting bracket.
3.Mounting and Wiring the New Unit:Mounting & Cable Gland Assembly.
Secure the BG2EDC1FR housing to the wall using the external mounting feet. Install certified Ex d cable glands into the M20 entry ports. Terminate the signal loop wiring onto the internal 2 CO screw terminals, ensuring proper placement of series/EOL resistors required by your fire alarm panel.
4.Testing and Commissioning:Seal Enclosure & Functional Test.
Ensure the internal O-ring seal is clean and correctly seated, then torque the cover bolts evenly to maintain IP66/67 integrity. Perform a test activation using the test key (or pressing the break-glass element) to confirm the fire panel receives the alarm condition instantly.
Firmware/Software Versions & Upgrade Notes
- Operating Nature: Pure electromechanical manual switch station; operates completely without software, firmware, or digital bus parameters.
- Fire Panel Compatibility: Compatible with all standard conventional and addressable (via address module) fire alarm control panels and emergency shutdown (ESD) systems.
- Resistor Integration: Verify if your fire panel requires specific End-of-Line (EOL) or Inline monitoring resistors; these must be fitted across the internal screw terminals during installation.
Frequently Asked Questions (FAQ)
Q: Is this MEDC BG2EDC1FR call point brand new or refurbished?
A: This product is a Brand New Surplus unit. It is not used, not pulled from a decommissioned plant, and not refurbished. All internal switches, terminal blocks, glass elements, and GRP enclosure surfaces retain original factory specifications.
Q: What do the suffix letters “EDC1FR” signify in the BG2 model code?
A: Breakdown of the BG2EDC1FR model configuration:
- BG2: Heavy-duty GRP Manual Call Point series
- E: Ex d (Flameproof) explosion protection
- DC: Double Changeover (2 CO / DPDT) switch contacts
- 1: Standard terminal arrangement
- F: Fitted with duty label / standard glass element
- R: Red enclosure color (Fire Alarm standard)
Q: Why is New Surplus essential for hazardous area life-safety devices?
A: Flameproof and weatherproof integrity in hazardous environments cannot be guaranteed with refurbished units. Thermal stress, mechanical wear on microswitches, or subtle cracks in GRP housings compromise ATEX/IECEx certifications. Sourcing New Surplus guarantees full compliance, maximum reliability, and eliminates liability risks.
Q: Can this unit be reset after testing without breaking the glass?
A: Yes, the BG2 series includes a specialized test key mechanism that permits routine functional testing of the internal microswitches without shattering the glass element.
Q: What warranty is provided with this New Surplus unit?
A: Every unit undergoes visual inspection, contact continuity verification, and mechanical seal checks prior to dispatch. All New Surplus purchases include our standard 1-year functional replacement warranty.
