DESCRIPTIONDESCRIPTION
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 installation instructions for the control panel in use for wiring
requirements for UL-listed applications.
WIRINGWIRING
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 reduce the amount of current available at the control panel’s
Auxiliary Power Output terminals.
MODULE ASSIGNMENTMODULE ASSIGNMENT
Regardless of how the modules are arranged, the expansion 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 consecutively (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-EZM8GEM-EZM8 GEM-EZM4GEM-EZM4 GEM-EZM8GEM-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.

PROGRAMMINGPROGRAMMING
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 proceeding 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

‘‘1’’ in two consecutive locations.

TAMPERTAMPER
If the cover is removed, the keypad sounder will pulse and
the display will indicate a zone-module tamper condition
along with the module number. Press [RESET] to silence the
sounder.
LOOP RESPONSELOOP RESPONSE
Loop response times for Zones 1 through 8 are programmed in the control panel. Normal loop response for
all expansion zones is 750mS. To reduce the response time
of an expansion zone to 50mS, cut the respective resistor
at the upper-left corner of the board. Refer to the Wiring
Diagram.
STATUS LEDSTATUS LED
The Status LED displays the condition of the zone module. The LED will blink every few seconds to indicate that
each 4-zone group is operating normally. The LED in the
4-zone module will blink once; the LED in the 8-zone
module will blink once for the first group, then double-blink
shortly thereafter for the second. See TROUBLESHOOT-
WIRING DIAGRAMSWIRING DIAGRAMS
PGM TERMINALPGM TERMINAL
The PGM terminal (Terminal 6) will go low when the area
is armed. This terminal may be used to light an LED or trip
auxiliary equipment. Note:Note: This terminal is programmed in
the control panel; it may be selected to trip when any one
area is armed (not necessarily its own). Refer to the installation instructions for the control panel for programmable
options.
4Z/8Z ZONE JUMPER4Z/8Z ZONE JUMPER
To convert an 8-zone module for use with only 4-zones,
remove the jumper just below the large microprocessor IC
on the circuit board.
TROUBLESHOOTINGTROUBLESHOOTING
• A steady Status LED is most likely caused by loss of
data reception from the control panel at the module’s
Terminal 3.
• No illumination is most likely due to a loss of power at
Terminals 1 and/or 2.
