DESCRIPTION
The capacity of the GEM-P1664 control panel may be expanded through the use of a GEM-EZM4/8 Zone Expansion Module. Each
GEM-EZM4/8 module provides up to 16 additional zones, and 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-P1664 control panel. Refer to the GEM-P1664 Installation Instructions and GEM-P1664 Programming
Instructions for wiring requirements. Note: Although the GEM-EZM4/8 may also be used with the GEM-P816 and GEM-P1632 control
panels, the features described in this addendum apply only to the GEM-P1664.
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 EOL (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.
