Rath MRI-1 - Life Safety Communication Hub for Intercom System Links

Rath - Avire MRI-1 Assembly, Machine Room Intercom is an innovative communication device that meets all the regulatory requirements while providing an easy-to-use way of establishing communication between the elevator machine room and elevator cab. This durable intercom system, consisting of a robust and durable stainless steel housing, is one of the critical elements of facility safety. It allows the technical and emergency personnel to reach out to the elevator passengers or other employees via the dedicated line.

As one of the most dependable pieces of hardware, MRI-1 intercom system is engineered specifically to provide seamless installation in any available elevator phone lines. In addition, it can be fixed on the wall or another flat surface, which makes the whole intercom system reliable and resistant to any kind of stress associated with an industrial setting.

What It Does

MRI-1 Assembly is a local node for your elevator communication system. It provides interruption to your phone line to establish clear and uninterrupted communication.

• Two-Way Intercom: It offers the possibility of direct communication between the machine room and the elevator phone in the elevator cab.
• Phone Line Sharing: The assembly automatically uses one and the same phone line both for intercom and for the elevator phone, which saves you from having to install additional phone lines.
• Emergency Override: If there is any communication ongoing via your elevator phone, the assembly will automatically disable such connection to allow you full access to the intercom system.
• LED Indicator: Integrated LED signal indicator lights when communication starts.
