DESCRIPTION
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.
WIRING
Wire the expansion zones to the module and the module to the control panel in accordance with the wiring diagrams shown using
wire no thinner than #22AWG. Install end-of-line resistors on all zones even if one or more zones are not used.
NOTE: The addition of Zone Expansion Modules will reduce the amount of current available by 60mA at the control panel's Auxiliary
Power Output terminals.
