5740 691 Norton Door Controls Door Closer
The 5700 patented design is based on ease and simplicity. This operator installs in minutes rather than hours and consists of three basic components: inverter, motor and NortonÃs 1601 closer body. What separates the 5700 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 closerÃs spring force. The 5700 is ideal for doctor's offices, retirement facilities, schools or churches. Based on its dual functionality, ease of use and quiet operation, the 5700 offers the customer a unique choice.
