TEI installs and services code compliant door and gate monitoring systems that provide elevator passenger safety. These systems will monitor door and gate contacts and if malfunctioning will hold the elevator at the landing, thus preventing automatic operation of the car if the car door is not closed.
TEI only installs equipment that is in complete compliance with NYC Building Code requirements. TEI utilizes monitoring devices that are universal and can be used on both processor and relay logic systems.
Monitoring systems are designed with redundancy checking. No relay failure will go unnoticed. Monitoring systems reset at each landing to reevaluate door and gate switch conditions.
