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.

CONFIGURATION (EZM GROUPS)
The EZM Group Configuration indicates how many zones the module will contain. Additional zones can be added in the following
configurations:
678910 11 12 13 14 15 16 17
Configuration 2 (8 Zones)
Configuration = 2 EZM
(Default Setting)
NOTE: If both zones in a zone-pair configuration (ex: zones 1 & 9 in the above diagrams) are to be used, then normally closed devices
must be wired to both zones. If Normally open zones for fire or panic devices are required, then the lower zone (2.2K EOL resistor)
must be used and the higher zone (3.9K EOL resistor) must not be programmed for any area. The 3.9K EOL resistor must be placed
across the terminals of the higher zone. For proper supervision, the 2.2K EOL resistor must be placed at the end of the loop.
EZM GROUP MODULE ASSIGNMENT
Regardless of how the modules are arranged, the expansion zones are
divided into consecutively-numbered groups of four. Each module may
comprise 1 group (4 zones), 2 groups (8 zones), 3 groups (12 zones) or 4
groups (16 zones). The EZM Group Assignment is done by configuring the
jumpers as shown in the above wiring diagrams. NOTE: The default setting
is 2 groups (8 zones).
BASE ADDRESS ASSIGNMENT
Every module must be assigned a unique “base address”. The Base
Address indicates which zones the module will contain. The base address
depends on the number of zones used by the previous module or by the
control panel. NOTES: (1) Groups must be numbered consecutively, that is,
missing numbers are not permitted. (2) No two modules may be numbered
alike.
Example. One GEM-EZM4/8 is used to provide 16 expansion zones to an
existing 8 zone installation, increasing the total to 24 zones. The next zone
available is zone 9, because the previous 8 zones are used by the control
panel. The GEM-EZM4/8 will provide zones 9-24 and its base address will
be "1" (see tables on next page).

wired to any of the first four zones (1-4) in this configuration.
NOTE: Normally open and normally closed devices may be
wired to any of the eight zones (1-8) in this configuration.

The base address is assigned to the module by proper selection of Address Jumpers (to the right of the LED) in accordance with the
following tables. Also refer to the Zone Wiring Diagram. Note: The GEM-P816 is limited to 16 zones.

PROGRAMMING
The control panel must be programmed with regard to the total number of zones required. When keypad programming the control
panel for the first time, the first programming option of the Easy Menu Driven Program Mode will be to enter the total number of zones
in the system, rounded up to the nearest four. You can then support this total by adding the appropriate number of GEM-EZM4/8
modules which can be configured as 4, 8, 12 or 16 zone modules. The number of modules required is a function of the number of
zones required as well as the configuration of the EZM's. If 24 additional zones are required and Config 2 (8 zones) is chosen, the
number of EZM's required will be 24/8 = 3 EZM's.
When downloading a control panel, the total number of zones is determined on the Zone Features screen by activating the required
number of EZM modules in the System Configuration screen.
For Fire Zones, if an EZM module is selected as Config 3 or Config 4, which are both zone doubled configurations, and one of
these doubled zones is programmed as a fire zone, the complimentary zone is lost. For example, if an EZM is configured as a 16 zone
module (Config 4), and zone 1 of the module is programmed as a Fire Zone, zone 9 of the module will lose the zone doubling profile
and cannot be used. It must be strapped out with a Z resistor (3.9K) across the zone. Zone 9 must be skipped in your control panel
programming, and the next available zone will be Zone 10.
TAMPER
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 C to silence the sounder.
LOOP RESPONSE
Loop response times for Zones 1 through 8 are programmed in the control panel. Normal loop response for all expansion zones is
750mS. The module already comes without the jumper installed (defaulted to 750ms). To reduce the response time of zones 1 through
4 of the EZM Module to 50mS, add the Loop Response Jumper. To enable normal loop response (750 ms), remove the jumper. Refer
to the Wiring Diagram.
STATUS LED
The Status LED displays the condition of the zone module. The following is a list of conditions for the LED:
1. OFF = Control Panel has no power applied
2. ON Steady = Control Panel has power applied but the panel is not polling because:
a. the panel is in "CONFIG",
b. the panel is not programmed correctly to poll the address of the EZM,
c. the GRN wire is not connected correctly.

This warranty contains the entire warranty. It is the sole
warranty and any prior agreements or representations,
whether oral or written, are either merged herein or are
expressly cancelled. NAPCO neither assumes, nor authorizes
any other person purporting to act on its behalf to modify, to
change, or to assume for it, any other warranty or liability

hereunder.
NAPCO RECOMMENDS THAT THE ENTIRE SYSTEM BE
COMPLETELY TESTED WEEKLY.
Warning: Despite frequent testing, and due to, but not
limited to, any or all of the following; criminal tampering,
electrical or communications disruption, it is possible for the
system to fail to perform as expected. NAPCO does not
represent that the product/system may not be compromised or
circumvented; or that the product or system will prevent any
personal injury or property loss by burglary, robbery, fire or
otherwise; nor that the product or system will in all cases
provide adequate warning or protection. A properly installed
and maintained alarm may only reduce risk of burglary,
robbery, fire or otherwise but it is not insurance or a guarantee
that these events will not occur. CONSEQUENTLY, SELLER
SHALL HAVE NO LIABILITY FOR ANY PERSONAL INJURY,
PROPERTY DAMAGE, OR OTHER LOSS BASED ON A
CLAIM THE PRODUCT FAILED TO GIVE WARNING.
Therefore, the installer should in turn advise the consumer to
take any and all precautions for his or her safety including, but
not limited to, fleeing the premises and calling police or fire
department, in order to mitigate the possibilities of harm and/or
damage.
NAPCO is not an insurer of either the property or safety of
the user's family or employees, and limits its liability for any
loss or damage including incidental or consequential damages
to NAPCO's original selling price of the product regardless of
the cause of such loss or damage.
Some states do not allow limitations on how long an
implied warranty lasts or do not allow the exclusion or limitation
of incidental or consequential damages, or differentiate in their
treatment of limitations of liability for ordinary or gross
negligence, so the above limitations or exclusions may not
apply to you. This Warranty gives you specific legal rights and
you may also have other rights which vary from state to state.
