MosaicONE Video & Messaging System

If you press the emergency call button in an elevator, but are unable to verbally respond, most monitoring stations will just hang up on you.

We don’t want this for you, your family, or anyone using an elevator.
No one should be left alone in silent distress. This is why we made MosaicONE VMS

IBC 2018 and A17.1/B44 2019 Code Requirements

Requirement Intent MosaicONE VMS
Two-Way Audio: Passenger that can hear and speak can verbally communicate with the emergency personnel N/A. Met through traditional elevator phone system.
Message Display: If a passenger does not verbally respond (possibly hearing impaired), emergency personnel can post a message on an in-car display Messages are posted in real-time on elevator position indicator screen and lobby panel via MosaicONE Cloud/LAN. Operator has ability to write any message or select from prewritten messages.

One-Way Video: Emergency Personnel can see into the elevator to assess situation, including passengers that can not respond. Live encrypted video of elevator interior available to remote monitoring station and fire control panel.

How Users Interact with the System

  1. A passenger places an emergency call by pressing the phone/help pushbutton

  2. Through the existing emergency phone system, a call is placed to the on-site attendant or monitoring station

  3. At the same time, a MosaicONE VMS tunnel is opened

  4. The attendant/monitoring station answers the phone and begins a verbal conversation with the passenger

  5. If the passenger does NOT respond, the attendant/monitoring station can visually confirm if there is a passenger in the car, and that it was not an accidental button press

  6. If passenger is present and has not responded verbally, the attendant/monitoring station can try to communicate with them by posting messages on the Matisse position indicator

  7. Passengers can either respond verbally or by pressing door open/close pushbuttons to answer "yes" or "no"

  8. If there is still no response (or unable to respond i.e. unconscious), with the visual confirmation of a passenger present, attendant/monitoring station can dispatch appropriate emergency personnel

How the System is Working

External Monitoring
  • The system monitors the phone/help button through a second contact
  • When the passengers press the button, the system sees the "press" and notifies the MosaicONE Cloud
  • MosaicONE flags the request and waits for an attendant/monitoring station to connect to the system.
  • When the attendant/monitoring station accepts the request, an encrypted tunnel between the monitoring station PC and the elevator is created. This can be done either through a predefined link, link sent via email, a web portal using phone-specified audio code, or in MosaicONE call center software
  • Through this tunnel, video and messages are transmitted between elevator and monitoring station.
Internal Monitoring
  • When the building has 24/hour internal monitoring, an external connection to the internet and creation of encrypted tunnel is not required since all devices are on the same network
  • When the button is pressed, the on-site attendant is directly notified on the MosaicONE platform, through which the video and messaging is done

Frequently Asked Questions

Can I provide my own Internet connection?

Code requires that there is 4 hours of emergency battery backup power on the system. An Internet connection is required for the system to work. The entire network needs to be on the 4 hours of backup, including switches, routers and modems. To ensure that it does, MAD is currently not offering buildings to provide their own connection.

Is the system secure from a cybersecurity aspect?

The MosaicONE VMS is completely behind a firewall. There are no open ports and all devices are invisible from anyone outside of the network. As a result, you cannot call into an elevator; the call must be initiated from inside the elevator cab for the monitoring station to have access to the system.

If a call is disconnected, can monitoring station reconnect?

Yes. For a short period of time, if a call is disconnected, the monitoring station will be able to call back/reconnect. After this time, a call would need to be re-initiated from inside the elevator.
