LEADINGEDGE by Tri-Tronics

The LEADINGEDGE® SERIES of elevator door protection systems are carefully designed to outperform, in every aspect, all door protection systems on the market.  The wide-angle lenses allow for the sharp turning radius of closing doors on round elevators.  Power supply enclosure is designed for easy installation and rated up to NEMA4.  Jamb mounting is simplified using our unique nylon snap-in fasteners.  The array cables are Hi-Flex robotic grade for extended life and are “connectorized” for ease of installation.  Save time and money with the built-in system test procedures. The power supply features a test button simulator for beam break (hold for obstruction/release to clear) and a push-to-test button that energizes the master control relay.

For installations without our power supply the light source and receiver arrays can also operate on virtually any controller power and input.  The NPN output from the receiver array is continuously short-circuit protected, and the array cable connectors are interchangeable. The supply voltage requirements are 12 to 30 VDC @ 125mA.
