ATCK Attack Kit for cabinets
EST3 supports several UL1635 certification installations. Each
of these requires that an ATCK Attack Kit be attached to an
RCC7R series control panel cabinet. The kit provides a two-
minute attack delay time.
The ATCK kit lets you replace the standard, hinged outer door
with a box cover that has no window. The cover attaches to the
backbox sides using sheet metal screws and four locks.
The kit also includes special knockout locks that secure the
unused knockout holes.
Follow the instructions shipped with the kit. In general, you’ll
need to:
1. Discard the standard door included with the cabinet.
2. For older cabinets, use the ATCK cover as a template to
mark and drill screw holes. (New cabinets include the
correct screw holes.)
3. Remove any unused knockouts and insert knockout locks.
4. Use the screws provided to attach the new cover.
