The “Complete” Prewired Photoelectric System

The dependable, ready-to-install system, with its unique redundant operation… if one eye fails, the other continues to operate the door.

The convenient ON/OFF switch keeps the elevator up while one eye is down.

Quick disconnects allow the eyes to be replaced with the unit in place, cutting downtime and saving expenses.

These Prewired Systems meet and exceed ADA (Americans with Disabilities Act) requirements along with state and local codes.

Manufactured in the U.S.A.
