The capacity of the GEM-P816 and GEM-P1632 control panels may be expanded through the use of GEM-EZM4/8 zone expansion module. Each GEM-EZM4/8 module provides up to 16 additional zones. It may be configured in a number of methods: 4 zones, 8 zones, 12 zones or 16 zones. Using any of these configurations, several GEM-EZM4/8 modules may be combined as necessary to supply the required number of zones to the GEM-P816 and GEM-P1632 control panels. Refer to the GEM-P816 Installation Instructions (WI994) and GEM-P1632 Installation Instructions (WI808) for wiring requirements for UL-listed applications. Note: The GEM-P816 is limited to 16 zones.
