Overview
The PC4632 is a MAXSYS graphic annunciator kit that displays zone status, troubles, device operation, and system events at a glance on a wall-mounted graphic layout. The PC4632 shows up to 32 events on a 8" × 11" (216 × 279 mm) display. It connects to PC4010/PC4020 MAXSYS panels over Combus and is programmed from an enrolled LCD keypad or DLS downloading software—same workflow as the rest of the MAXSYS system.
The companion PC4664 model offers 64 events on a larger display; setup and programming are similar (see shared install manual).
