Stanley Security Solutions released the D-4990 Low Energy Power Operator for entrances and automatic door applications. The operator is designed to be in compliance with the Americans with Disabilities Act.
The device combines the power of a Stanley’s motorized opener with the efficient mechanical function of the company’s heavy-duty door closer. Even without electrical power or power failure, the door operator is fully operational because the door closer works independent of the motor.
The device also includes the following features: A “push and go” option that gives users a field-selectable switch to initiate automatic opening sequence during manual operation; a hold-open timer, which provides hold-open for up to 25 seconds after signal activation; an External Switch that provides continuous hold-open; an obstruction-detection system; and a power-close Option - for openings that require additional closing force to overcome interior stack pressures, weather stripping, etc.
