Lobby and MachineRoom Communication Systems

Per ASME A17.1 2019/CSA B44-19 ‘Safety Code for Elevators and Escalators’, buildings where elevators travel is 60 feet or more, must install in building rescue coordination. Positioned strategically in the building’s lobby or machine rooms, our Lobby and MachineRoom options serve as the first point of contact for elevator maintenance teams and first responders. This offers them a comprehensive overview of the situation within each elevator, providing rapid response times and informed decision-making.

Elevator 2D & 3D Door Detection

Elevator doors are more than just a gateway to vertical transportation; they are a critical component in ensuring the safety of passengers. However, they also represent one of the most significant risk points within an elevator system. Elevator Light Curtains (Safety Edges) act as protective barriers across elevator doors using infrared sensors. When an obstruction, like a passenger or object, interrupts this barrier, the doors automatically reverse to prevent accidents.
There are two main types:
  • 2D Detection Systems: Positioned between the elevator doors, they ensure nothing gets trapped during closure
  • 3D Door Detection Systems: Beyond monitoring between the doors, they also detect obstructions in the landing area, offering superior safety

Elevator Communications Failure

In the realm of elevator safety, continuous communication is paramount. Elevator emergencies can be distressing, and the last thing one would want is a non-functional communication line. Recognizing this, the ASME 17.1 code has set forth specific requirements to ensure that elevator phone lines are always monitored for activity and operational.
Phone Line Monitoring requirements include:
  • End-to-End Monitoring
  • Immediate Alerts
  • Location Specific Alert
