Developed to optimize performance and minimize downtime, Remote Elevator Monitoring — REM® — tracks hundreds of system functions on thousands of elevators around the world. The REM system is available on all Otis Microprocessors and Dover DMC equipment.

REM Makes the Call
If the REM system detects a problem, it correctly diagnoses the cause and location, then automatically makes the service call — dramatically reducing the time your system is out of service.

Fast Response
If the REM system detects an urgent problem, it reports the condition to the OTISLINE 24-hour communications center, and an Otis mechanic is dispatched if necessary. Elevators are often back in service before you or your tenants realize there is a problem.
Preventing Callbacks
The REM system identifies most problems before they occur. REM detects deteriorating components and intermittent anomalies, and notes the small nuisances that might have gone undetected until they caused service.

    A Diagnostic software monitors elevators continuously and sends data to the REM unit located in the machine room.

    B The REM unit sends this information to the OTISLINE center.

    C Data is categorized by urgency and reviewed by OTISLINE representatives.

    D An OTISLINE representative alerts the field mechanic, if necessary.

    E The mechanic arrives at the job site with specific information, tools and parts to work on the elevator.
