DESCRIPTION

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

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:

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

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

Base Addr ‘‘1’’

Base Addr ‘‘3’’

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

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

GEM-EZM4, GEM-EZM8

GEM-EZM4, GEM-EZM8
