Brookfield Industries, Inc. Series NB-500 Standard Swinging Door Operator NB-500

The brookfield NB-500 Swinging Door Operator has been designed, tested and is manufactured by brookfield industries, inc. in accordance with UL 325 and ANSI 156.10 for linear accelerator swing doors weighing up to 4,500 lbs and 66” wide. The NB-500 can be expected to safely operate doors at the maximum weight and width for at least 500,000 cycles, providing the door is set within the ANSI 156.10 speed criteria and the rated operating torque of 1000 lb-in (reflected to the operator) has not been exceeded. If any one of the following: torque, weight, width or cycles exceeds the rated value, please contact the Engineering Department for further evaluation. This power open/power close electro-mechanical operator with its state of the art components and mostly all aluminum construction, make it the lightest and strongest in the industry today. Refer to the Wiring Legend for Terminal Strip Hookup for all open, partial open, close, stop and safety device inputs, which are all Class (2) 24VDC momentary contact (except terminal 9 which must be a maintained contact). Power supply hookups for both Class (2) 24VDC and 110VAC are also indicated. The PLC then processes all this information, in addition to many other features for proper control of these heavy lead doors, which are patented under US Patent No. 6,177,771 B1. We are Authorized to Mark the NB-500 with the ETL (US and Canada), and CE markings from Intertek Testing Services to assure compliance with UL 325(Control No. 3011624), FCC Part 15 (Emissions) and the following International Standards: EN 60335-1 and -2 (Safety), EN 61000-6-2 (Immunity), EN 61000-6-4 (Emissions), CAN/CSA-C22.2 and ICES-003. The "listing" reports specifically refer to the heavy commercial/industria l doors associated with linear accelerator rooms.
