DESCRIPTION

The capacity of the MA3000, GEM-Series and Signature 5500 and SS-P Series control panels may be expanded through the use of GEM-EZM zone expansion modules. GEM-EZM4 modules provide up to four additional zones; GEM-EZM8 modules, up to 8 additional zones. Four-zone and 8-zone modules may be combined as necessary to supply the required number of zones. Refer to the installa- tion instructions for the control panel in use for wiring requirements for UL-listed applications.

WIRING

Wire the expansion zones to the module and the module to the control panel in accordance with the wiring diagrams 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 re- duce the amount of current available at the control panel’s Auxiliary Power Output terminals.

MODULE ASSIGNMENT

Regardless of how the modules are arranged, the expan- sion zones are divided into consecutively-numbered groups of four. Each 4-zone module comprises one group of zones; each 8-zone module comprises two groups.

Every module must be assigned a unique ‘‘base address’’. In the case of a 4-zone module, the base address number is the same as its group number. For the 8-zone module, the base address number will be the lower of its two group numbers. Note that (a) groups must be numbered con- secutively (that is, missing numbers are not permitted); and

(b) no two modules may be numbered alike.

Example. Two GEM-EZM8s and one GEM-EZM4 are used to provide 20 expansion zones:

Groups 1 & 2	Group 3	Groups 4 & 5
GEM-EZM8	GEM-EZM4	GEM-EZM8
Base Addr ‘‘1’’	Base Addr ‘‘3’’	Base Addr ‘‘4’’

The base address is assigned to the module by proper selection of Address Jumpers JP1-JP5 (to the right of the LED) in accordance with Table 1. Also refer to the Zone Wiring Diagram.

PROGRAMMING

The control panel must be programmed with regard to the modules (4-zone or 8-zone) in use. Referring to the respective Programming Workbook, program EZM TYPE to enable the module. Starting in the first location and pro- ceeding in succession, program a ‘‘1’’ for each 4-zone group of expansion zones in the system. For example, if one GEM-EZM8 is used for Zones 9 through 16 (two groups of 4), program a ‘‘1’’ in the first and second locations (right ‘‘nibble’’). Similarly, if an GEM-EZM4 is used for Zones 17 through 20 (1 group), program a ‘‘1’’ in the third location (right ‘‘nibble’’). Thus, each GEM-EZM4 will require a ‘‘1’’ in only one location whereas each GEM-EZM8 will require a
