Gateway Park Center PERKINS+WILL 810495.000 12/06/18 AUTOMATIC VERTICALLY RETRACTABLE GLASS WALL 08 33 36 - 3 key switch, or, in the optional scenario, using two touch screen operator stations. In the standard, push button scenario, turning the key from the “off” position shall cause the wall to move in the designated direction “up” or “down” once both push buttons are depressed. In the optional, touch screen scenario, pressing and holding the up or down directional arrow symbol on one touch screen while simultaneously pressing and holding the button symbol on the second screen shall cause the wall to move in the selected direction. In both scenarios, when hand pressure is removed, the wall shall immediately stop. The operable wall shall stop in a quick and positive fashion without coasting. As a normal part of the operation, it shall be possible to partially open (or close) the wall, stop it and then reverse the operation. There shall be two (2) switches per operable wall, located on opposite sides of the wall at opposite ends of the wall, wired in series. In the standard condition, one switch shall be equipped with an LED that flashes fault codes in case of a failure with the electrical system. In the optional, touch screen scenario, the screens will display faults in case of a failure with the electrical system. C. The motor assembly is mounted directly above the centre line of the operable wall. Support steel is only required at one location D. Electrical: 1. The operable wall shall be equipped for a three phase power supply to the electrical control box. 2. Standard electrical control box will be NEMA 1. NEMA 4 is also available upon request. 3. Low voltage wiring (by others). 18 gauge wiring from the switches to the control box. 4. Switches (standard): Two (2) push button switches wired in series with power controlled by a single, three position key switch. One switch shall be equipped with an LED that flashes fault codes in case of a failure with the electrical system. (Installation and wiring by others). 5. Touch Screen Operator Stations (optional): Two (2), 4.3” resistive LCD touch screens, wired in series with multilingual capabilities and 4 digit adjustable user pin. The screens will display faults in case of a failure with the electrical system. (wiring by others) E. Safety Equipment: 1. The operable wall shall employ an electromagnetic type of brake which shall activate firmly, without hesitation, when power is lost to the system. This brake shall have a minimum retarding torque rating equal to 200% of the power drive full load torque. The drive system shall be equipped with a manual override and brake release lever. The operable wall shall employ a dynamic brake, distinct and separate from the brake above, in order to lower the operable wall at a controlled speed of no more than approximately 150% of the normal down speed, in the case of a catastrophic failure in the power train. Alternately, the operable wall shall employ a brake, distinct and separate from the brakes above, in order to completely halt the downward motion of the operable wall in the case of a catastrophic failure in the power train. 2. The operable wall shall employ electrical or other limit switches in order to stop the wall at the up and down travel limits. 3. The operable wall shall employ an over torque detector in order to sense a jam in the system and to act as an over travel limit in the up direction should the
