The 5700 Series LEO by Norton Door Controls is a door closure designed for ease and simplicity. The LEO installs in minutes rather than hours and consists of three basic components: inverter, motor and a standard Norton 1601 Series closer body. Quiet operation makes it ideal for schools and any location where noise is a major concern. When the door is opened manually, there is minimal resistance, and the drive train and motor are not engaged. The 1601 closer, not the motor, controls the closing cycle. This makes the operator efficient and, even with loss of power, the door can be manually opened and will close via the door closer’s spring force, according to the company.LEO is listed with UL and ANSI/BHMA A156.19 and meets the requirements of ADA and ANSI/BHMA A156.4.
