LC106EX-04-1PB One-Button Explosion-Proof Emergency Intercom (SIP & Analog) | ATEX, IECEx, EAC and INMETRO certified | 2-Year Warranty.
The One-Button Explosion-Proof Emergency Intercom (SIP & Analog) is a certified emergency communication device designed for hazardous and explosive environments where safe, instant voice communication is critical.
Housed in a corrosion-resistant aluminum alloy enclosure, the unit is engineered to prevent ignition, contain internal explosions, and withstand extreme industrial conditions, including high humidity, salt spray, mechanical impact, and wide temperature variations.
A single heavy-duty explosion-proof button enables immediate, hands-free emergency calling, ensuring fast response without complex user interaction. The bright industrial orange finish and integrated LED indicator provide high visibility in low-light, smoky, or confined areas.
The key advantage of this system is its native compatibility with standard Analog and SIP PBX systems, allowing seamless integration into existing telecom infrastructure without proprietary gateways or custom platforms.
