Product Details | Innovative Apart from the extended cover, DORMA also provides an easy-to-install integrated door coordinator for double-leaf doors. With the aid of the DORMA Upgrade Card, the system’s functional range may be adapted to various door versions. The large scope of integrated functions further ensures that the majority of possible applications can be readily accommodated. Users may choose between two operating modes: Door Closer and Automatic mode. While set to the Door Closer mode, the ED 250 swing door operator is optimized for manual operation. With its optional Power Assist function, the Door Closer mode is tailored to predominantly manually operated doors where a door closer function is desired. The Automatic mode, in turn, is especially suitable for mainly automatic access with a motion detector or pushbutton actuation. The ED 250 swing door operator is especially suitable for exterior doors that are subjected to varying wind loads and for interior doors separating rooms where different air pressures prevail. While the system is in Automatic mode, the wind load control monitors the actuation speed, keeping it constantly at the preset value. The ED 250 swing door operator’s Power Assist function may be activated while the door is in Door Closer mode. As soon as a user opens the door by a couple of degrees, the servo function cuts in to support the manual opening cycle, automatically adjusting to the preset closing force as effort is applied. |
