About Lift-Net™ Monitoring and Control What Can The IDS Lift-Net™ Do For You?

Display elevator system status on multiple CRT screens anywhere in the building – security stations, lobby, engineering, machine room, all connected by simple twisted pair cabling.Provide mouse or CPU clock control of security features such as Selected Floor Lock-Out, Suspicious Person Return, Hospital Code Blue, VIP Service, Up/Down Peak, and Lobby Recall.Revitalize lobby using modern color CRT displays and keyboards to replace obsolete light bulb style lobby panels and key switches; no more light bulbs to change or key switches to break. Add new features easily without running any new wires.Trigger emergency audio and video alarms to allow immediate response to crisis situations.Interface to Lift-Net™ Voice.Log error type, car number, floor position, and system status whenever a fault occurs. Detect intermittent failures early, before they become big problems.Perform statistical analysis on hall response times and traffic patterns. Find the bottlenecks that are slowing system response. Optimize zone patterns for peak performance.

Because elevator systems vary widely in complexity, our equipment is designed to be flexible, modular and adaptable. On every installation we work diligently to tailor our design to satisfy the customer's specific goals.


Compare Lift-Net™ to OEM Elevator Monitoring Systems
Lift-Net OEM Elevator Monitoring Systems
Lift-Net is a stand-alone system specifically designed to monitor and control all makes and models of elevators. Typical OEM monitoring systems are add-on features incorporated into controllers whose primary duty is to run, not monitor, the elevators.
Lift-Net™ allows different makes of elevators to co-exist on the same network and be viewed and controlled on any network monitoring station. Most OEM systems allow only one manufacturer's equipment to be monitored.
Lift-Net™ allows multiple banks of elevators, even multiple buildings to be monitored and controlled on any network monitoring station. OEM systems usually need one monitor per bank of elevators; at best they require a separate monitor for each building.
Lift-Net™ presents a consistent user-interface to the operating personnel regardless of the types of elevators being monitored. If there are several different makes of elevators being monitored, operating personnel must learn to work several different monitoring systems.
Lift-Net™ provides a common set of fault, traffic, and operating data, measured and displayed the same way for all monitored elevators. Each manufacturer measures fault, traffic and operating parameters in a different way. It can be difficult to compare one system to another.
Lift-Net™ features a convenient and familiar Windows interface, with all actions carried out by mouse click. OEM systems often use a text based operating system with arcane menu and keystroke commands.

Lift-Net™ Overall View

Lift-Net™ Micro Controller Machine Room Scanners record elevator equipment status inputs and publish the data on a specifically designed network.Every monitoring station has access to information from every elevator system, and can control relay outputs located anywhere on the network. Monitoring stations can be connected in any convenient order as long as the "Daisy Chain" configuration is maintained (see diagrams for details or click here for more details).


RS-422 Network   RS-485 Network   LAN/WAN Network

With Lift-Net™, a security officer in the lobby can return cars to the main floor, while an engineer in operations is analyzing traffic patterns, and a technician in the machine room is scrutinizing fault data all on the same elevators at the same time.




Lift-Net™ Options
Lift-Net™ provides a convenient and logical interface for building management, security, and maintenance staff to efficiently monitor and control the elevators for which they are responsible.The Following modular options expand the capabilities of the Lift-Net™
Relay outputs to control any aspect of the elevator system. Controls may be initiated by mouse click or internal real time clock. This allows a remote monitoring station to duplicate or replace the functions of key switches, push buttons, or program clocks, regardless of the location:

  • Some possibilities of this versatile feature include Security Lock-out of all or selected car and hall buttons, Lobby Recall, Code Blue, VIP Service, UP/Down Peak, or similar group functions.
  • All Controls may be password protected. New features can be added to an existing installation without running more wires or mounting new key switches.
  • All controls are designed to operate smoothly with existing emergency systems. In the event of a system failure, Lift-Net™ controls will fail-safe.
  • Lift-Net™ controls are extremely flexible and can be tailored to any specification.
Monitor Car Buttons:

  • Registered car calls are visible in real-time on the Lift-Net™ main screen. With the car call option security personnel can more effectively monitor building traffic, or the maintenance staff can identify a stuck or malfunctioning button.
  • Car button statistics are available in the Car Use Reports, to provide a more complete picture of system traffic.

  • An uninteruptable power supply can keep the Lift-Net™ system up during a building power failure. The last known locations of all the monitored cars will be visible on screen to aid rescue operations.
Lift-Net Voice

  • On screen identification of caller location.
  • Complete log of all communications activity.
  • Optional link to public telephone system.
