CRL Norton 5700 Series is a new generation of power door operators. The patented design of LEO is based on ease and simplicity. LEO installs in minutes rather than hours, and consists of three basic components: inverter, motor, and Norton's 1601 Closer Body. What separates LEO from other operators is its ability to function as a standard door closer. When the door is opened manually, there is little resistance, and the drive train and motor are not engaged. The 1601 Closer, not the motor, controls the closing cycle. Since the door closer does not back-drive the motor during the closing cycle, there is no loss of closer efficiency. In the event of a power outage, the door can be manually opened and will close via the door closer's spring force. LEO is listed with UL and ANSI/BHMA A156.19, and meets the requirements of A.D.A. A156.4. It is ideal for offices, retirement facilities, schools, churches, and any location for ADA handicap assist openings where extra features are not required and noise may be a concern. This operator is not intended to be used for full time automatic opening applications. The 5700 LEO can be activated via wall switch, radio frequency device or motion sensor, and is available for both push and pull side applications. Based on its dual functionality, ease of use and quiet operation, LEO offers the customer a unique choice.
