The ADAEZ door opener is a state of the art system designed for heavy use commercial applications. The "ADAEZ Pro Complete package" contains everything you need in one box for doors that push to open with no strike to disengage. Strike releases are available as an option. The ADA EZ Pro Complete kit includes 2 wireless buttons, push mount or pull mount hardware and can be handed in the field as a right or left hand swing. Manual usage of the door will trickle charge the onboard lithium ion battery by utilizing a regenerative drive system* which keeps the battery fully charged and ready for power activation if you choose not to use the included power supply. There is no need for an electrician or special skills to install the ADAEZ opener and the power supply is a simple plug-in transformer. A fully charged battery will typically power the ADAEZ for approximately 2000 activation cycles.
