Commercial Applications
The Model 233
The Model 233 automatic door opening system is perfect for use in commercial applications like storefronts, schools, apartment lobby doors, screen doors, restrooms or any application where the unit replaces a door closer. When activated by pushpad or remote control the opener will go through the open-pause-close cycle. The system is easy to install and low voltage which means no electrician is necessary for wiring. The units take up a small footprint and cost less than most other commercial units.
When the door is opened manually the door will power close as if it were operated by a spring or pneumatic closer. The Model 233 unit also includes a variable clutch which allows modification of the closing speed depending on need and wind conditions.

The automatic door operator is electromechanical, and provides for both powered opening and powered closing of a door. The door opener acts like a door closer when the door is manually opened, producing an ADA compatible closing force.
The unit shall contain an internal battery power supply to provide powered operation in the event of external power failure. The unit shall be powered by 24 vac, external to the device under provisions of low voltage wiring and is supplied with a 20 VA transformer requiring 115 vac 60 Hz service.
The operator shall be mounted according to drawings and instructions provided with each unit. The unit shall be capable of mounting on either door or lintel and shall provide door opening angles up to 120 degrees. Can also be used for gates if a rain shield is used to protect it.
The unit shall possess an adjustable hold-open feature allowing the door between 5 and 30 seconds for passage.
Electro-mechanical. Power open, power close. Constant torque slipping-disc clutch engagement at all times.
Automatic open-hold-close cycle (5 to 30 seconds) activated by a signal from internal radio receiver or the momentary closure of electrical contacts provided by wires to unit.
Automatic cycle may be interrupted by a signal received within the cycle bringing the operator into a non-active parked state. Door may be closed remotely if the door is left open in an inactive state upon receipt of a signal.
Optional Mode (No-Park setting) - does not allow automatic openhold-close cycle to be interrupted after cycle is started.
