Lobby & Machine Room Communication

Lobby & Machine Room Communication systems are critical for maintaining clear, real-time communication between the elevator cab, building lobby, and machine room. These systems help streamline emergency response, maintenance coordination, and service operations by ensuring reliable voice connection across essential points of the elevator system.

RATH® and JANUS® Lobby & Machine Room Communication systems include both analog and IP-based options, offering hands-free, point-to-point or multi-point communication. Designed for easy integration into new construction and modernization projects, these systems enhance safety, responsiveness, and operational efficiency.

All RATH® and JANUS® Lobby & Machine Room Communication systems are designed with code compliance in mind. Many models meet applicable requirements from NFPA, ASME, CSA, ADA, IBC/ICC, and UL, helping support safe and reliable communication throughout the elevator environment.

Elevator Communication Systems

Includes EMS5, SmartRescue, and Command Center systems designed for elevator communication.

Command Centers

RATH® Command Centers provide centralized communication between designated emergency personnel and elevator passengers during an entrapment or system fault. These stations are typically installed in building lobbies or security offices and serve as the primary point of contact for responding to elevator calls. With multiple form factors and interface options, RATH® Command Centers support direct, reliable two-way voice communication and are designed to meet NFPA, ASME, CSA, and ADA requirements. They are ideal for new construction and retrofit projects where clear communication and code compliance are required.

SmartRescue System

RATH® SmartRescue System is an integrated solution that provides two-way emergency communication from designated areas, such as stairwells or areas of refuge, to a central command point. In addition to its primary function, the SmartRescue System can serve as a lobby or machine room communication hub when paired with elevator system components. Designed for life safety applications, RATH® SmartRescue System supports hands-free communication and real-time status monitoring. It meets NFPA, IBC/ICC, and ADA requirements and is ideal for facilities that need to combine elevator communication with broader emergency response coordination.
