GENERAL DESCRIPTION
The GEM-ACM1D is an accessory that adds integrated
access control to the burglary alarm functions of the GEMX255 control panel. It provides controlled access to a door
by releasing a locking device (such as a magnetic lock or
electric strike) when the proper credential is presented to
the card reader. Access control is integrated with the burglary functions of the GEM-X255. It can be used to arm
and disarm the system, annunciate and report alarms and
troubles, and monitor the access door without the need for
additional contacts.
Up to 4 GEM-ACM1D modules may be connected to a
GEM-X255 control panel via standard, unshielded station
wire. Each module is capable of controlling access
through 2 doors and uses a keypad location in the system
for communication. Any polling failures, AC/DC Power or
Battery Troubles associated with the ACM will be displayed as a
KEYPAD/ACM TROUBLE
Any ACM tampers will be displayed as a
TAMPER
at the other keypads. GEM-X255 panel code version 5 or higher must be used for GEM-ACM1D module
installations.
Although the GEM-ACM1D performs all access decisions
immediately without consulting the panel, the panel limits
the number of users to 195. In addition, the Event Scheduler (requires use of PCD-Windows) is used to control user
access by scheduling "User Off" and "User On" events,
with the total number of events is limited by the panel to
255.
Be aware that more than one event can be
Note:
assigned to each user, and the total number of events allowed is always limited to 255 regardless of how many users are programmed.
The GEM-ACM1D requires the panel for uploading user
codes/attributes (and their associated schedules), uploading door attributes, digital dialer reporting and all Keypad/
ACM trouble/information displays.
Each of the two model 6005B access card readers can be
programmed to function independently on different doors,
or together controlling access for both sides of one door.
The GEM-ACM1D supports a variety of card readers, including the Polaris XYZ magnetic card reader, the ShadowProx proximity card reader, the HID proximity readers,
and the 26-bit standard Wiegand card readers. The GEMACM1D also supports the use of any "Request to Exit" device, including the T-Rex exit detector.

GEM-ACM1D Power Supply
The GEM-ACM1D has an integral power supply which includes two primary linear regulators. The first regulator is
used to power the panel, the card readers and to re-charge
the battery. The panel and card readers are supported
with battery standby. The second regulator is used to supply up to 1.5A 12VDC for the door locks, which provides
enough current to support two 750mA magnetic locks.
The Door Lock Power has an option to enable battery
standby with a shunt connector placed across jumper JP3
(factory default). The battery is prevented from damage
caused during extended power failures with a battery drop
out circuit that disconnects the battery when there is no AC
present and battery voltage drops to approximately 9VDC.
When AC is restored, the battery is automatically reconnected and begins to recharge.
The GEM-ACM1D tests the battery under load every 4
hours and when the RESET button is pressed. The low
battery condition will only restore after it passes the active
test. The duration of this test is 15 seconds.
There are several advantages to this power supply design.
The separation of the door lock power from the rest of the
system reduces the likelihood that turning off the power to
the door lock coils will affect performance of the system.
The use of linear versus switching regulators significantly
reduces electrical noise that may hinder the sensitivity of
proximity card readers.
LIST OF ACCESSORIES
HID Prox Point Plus Model 6005B
Any UL 294 Listed door lock
Proximity cards: Two card formats are supported:
(1) NAPCO standard 36 bit format or
(2) HID standard 26 bit format.
SYSTEM REQUIREMENTS
The following system hardware is required:
Gemini GEM-X255 Control Panel version 5 or higher.
EPROM Upgrade must be installed in control panel.
PLAN YOUR INSTALLATION
Before installing your GEM-ACM1D access control accessory, give careful consideration to the design and physical
layout of the system. Access control points, keypad
zones, ACM zones and all other system components
should be planned in advance to ensure an efficient and
complete installation. It is recommended that you perform
all installation steps in the same sequence as is listed in
this manual.
After selecting all access locations, be sure to then locate
the GEM-ACM1D as closely as possible to the selected
access control doors, easily accessible for servicing, and
within 1000 feet of the GEM-X255 control panel. Standard
22-24 gauge wire is recommended for all connections between the panel and the GEM-ACM1D, and 18 gauge wire
for all door strikes. Avoid running wires parallel to other
types of wiring that can cause electrical interference.
Typical Installations
There are two basic ways the GEM-ACM1D may be installed to provide access control, both are described below:
Option 1 uses a single card reader on the exterior of the
restricted area and a "Request to Exit" button within the
restricted area. This method only requires a single card
reader for each access door. This method is limited in
that only entrance via the card reader is logged or
§
printed
. The use of the "Request to Exit" button is not
logged (anyone can exit).
Option 2 uses 2 card readers (one reader mounted inside and another outside the restricted area); both connected in parallel to a single card reader interface. This
method requires presenting the credential for both entry
and exit from the restricted area. Although each presentation of the credential is logged and printed
†
, whether
the presentation was used to enter or exit the restricted
area cannot be determined.
Integrating the Fire Alarm System
Before installing the access control system, be sure to consult with the authority having jurisdiction to be sure to comply with all local codes. NFPA requires that the Fire Alarm
System has some control over the access doors. In the
event of a Fire Alarm or the loss of primary power (typically
AC), all access doors must be unlocked.
The "Emergency Free Access" zone is designed for this
integration. The output(s) from the fire alarm system must
be wired so that if there is a fire alarm or AC failure of the
fire alarm system, the "Emergency Free Access Zone" is
either shorted or opened. See page 3 for recommended
programming and wiring information.
Keypad Placement
A keypad should be located near any access door that can
be used to arm the system, so that the status of all the
zones up to the door can be determined (UL grade A requirement).
Additional Accessory Requirements
Up to three GEM-X255 zones may be dedicated to each
Access door. These three zones are the (1) Door, (2)
Forced Entry Zone and (3) Door Ajar Zone. If used, each
of these zones (up to 24 on a full system) will require either
1 of the 8 panel hardwire zones, a GEM-EZM8 zone or a
Wireless zone. If the zone is not 1 of the 8 panel zones,
then either (a) the zone will require the correctly addressed
GEM-EZM8 to be physically wired to the system, or (b) a
wireless receiver (GEM-RECVX 8/16/96/255) must be
physically wired to the system.
§ A GEM-PRINT is required on the system to print.
†
A second GEM-ACM1D could also be used.
2
Access Groups
Useful when designing an access control system, an Access Group is a collection of users who all have similar at-
tributes; they all enter and exit the same access door, and
all keep to the same basic schedule when using the system. To keep the system organized and easier to manage, these users can be given a group name and assigned
to a specific range of contiguous user numbers (total range
is 1-195). Thus when deactivating and activating cards is
required, errors as to scheduling and other attributes can
be minimized. For new installations, we recommend that
installers program several users into the system (all with
similar attributes) to help reinforce the concept of Access
Groups for future programming.
INSTALLATION/MOUNTING INSTRUCTIONS
After the mounting location and all access control doors
are selected, install the GEM-ACM1D as follows:
1. Install the GEM-ACM1D. The GEM-ACM1D housing
is designed for vertical surface mounting indoors in a
dry, secure location. When selecting a mounting location, ensure that the housing is accessible when future
servicing is required. Back-up battery must be located
within the secure housing. Mount the housing using the
two middle mounting holes and at least one bottom
mounting hole. Important Note: The GEM-ACM1D is
powered by a linear power supply which is the preferred
power supply for card proximity readers due to their
very low electrical noise (compared with switching
power supplies). However, be aware that linear power
supplies do generate moderate heat. Therefore mount
the GEM-ACM1D in a location that provides air circulation around the unit, particularly directly above the
housing. Do not install the GEM-ACM1D in confined
locations. Note: For UL installations, the GEMACM1D must be mounted within a protected premises.
2. Install Accessories. Mount all devices for each controlled access door:
a. Mount all required keypads.
b. Mount access card readers.
c. Connect door strikes (mag locks). Recommended
door strikes are "Fail Safe" locks which open when
power fails.
Note:
Local jurisdictions may prohibit
"Fail Secure" locks (which remain locked when
power fails) for fire escape routes.
d. Door contacts must be hardwired directly to the
GEM-ACM1D. Do not use wireless contacts.
e. Optional accessories such as an egress button, au-
dible silence button, etc. should be mounted inside
the restricted area.
3. Install Tamper Switches. J1 must be cut to enable
tamper. Normally open tamper switches (not supplied)
can be installed in the front and back of the cabinet to
provide protection from unauthorized entry. The tamper
switches are normally open switches used in a normally
closed tamper circuit. The front tamper switch protects
the cabinet door and the back switch protects against
removal from the wall. The normally open tamper
switches are connected in series between terminal 11
(positive +12V) and terminal 12 (ground). Note: UL
requires that the unit is mounted inside the protected
premises and therefore does not require tamper
switches to be installed.
4. Remote AC On Indicator. Dedicate a zone to each
GEM-ACM1D in the system with the following features:
“Never Arm”
•
• Do not program “Burg Output”, “PulseBurg Output” or
“Fire Output”
Program the zone for the area of the GEM-ACM1D
•
and GEM-2D (if used).
• Program the zone description “GEM-ACM1D X AC
FAIL” where X= the number of the GEM-ACM1D.
5. Other Connections. Wire earth ground to terminal 13
using a No. 16 AWG. or larger wire to a metal coldwater pipe. Do not use a gas pipe, plastic pipe or AC
ground connections. NOTE: Grounding connections
should avoid bends in the grounding wire whenever
possible.
6. Connect Transformer. Install a 16.5VAC/40VA transformer to provide power to the GEM-ACM1D. Connect
the red battery lead (E200) to the positive battery terminal and the black battery lead (E201) to the negative
battery terminal. Do not apply power until all wiring/
connections are complete.

FOR UL INSTALLATIONS
The following is required in UL installations:
1. The GEM-X255 must be installed and programmed as
required for the application.
2. A keypad must be located next to any access door, to
provide an indication (at the time of arming the system)
that all protection up to the egress door is set for duty
and the status of the GEM-ACM1D primary power.
3. Follow procedure on page 3, INSTALLATION/
MOUNTING INSTRUCTIONS, Step 4, "Remote AC
On Indicator".
4. Install front and back tamper switches as described in
the Installation Instructions provided (WI1278).
5. Use Prox Point Plus Model 6005B as card reader.
6. Use only UL Listed door locks.
7. Remove shunt connector from JP3 (remove battery
standby from D1 PWR and D2 PWR) assuring minimum 4 hour battery standby of GEM-ACM1D burglar
accessory functions.
8. Follow wiring notes on GEM-ACM1D Wiring Diagram.
WIRING/CONFIGURATION
All inputs and outputs, door strikes, card readers and all
other accessories should first be installed as detailed
above. Also, place all correct shunt connectors on jump-
INSTALLATION/MOUNTING INSTRUCTIONS
ers. Note: Do not apply power until all wiring is complete.
Both AC and battery connections must be made before the
GEM-ACM1D will function properly. Always connect the
AC power before connecting the battery to avoid system
troubles.
Refer to the wiring diagram on page 23.
1. Connect to the Remote Bus. GEM-ACM1D Termi-
nals 7-10 provide the control panel interface. Connect
as per the table below:
Table #2: Remote Bus Connections
GEM-X255 Terminals GEM-ACM1D Terminals
9 (+) 7 (+)
10 (-) 8 (-)
11 (TX-Green) 9 (RX-GRN)
12 (RX-Yellow) 10 (TX-YEL)
2. Connect Electric Door Locks.
NOTE: Before installation, always check with local
laws having jurisdiction concerning the installation of
magnetic locking devices. There may be strict limitations with regard the installation of magnetic or similar
exit door locking devices. Local laws may require the
installation of electrically separate panic hardware to
ensure the door can be opened in the event of an
emergency.
Door lock outputs are controlled by schedules pro-
grammed into the panel. These door lock outputs can
operate DC-powered locking devices such as magnetic
door locks or other electromechanical locks and can be
configured to operate in "Fail Secure" (which remain
locked when power fails) or "Fail Safe" (which unlock
when power fails) configurations.
For normally de-energized door locks, connect ground
to terminal 4, wire terminal 3 to terminal 14, then connect the positive door strike wire to terminal 16. See
wiring diagrams (Figs 1 and 2 below) for both normally
energized and de-energized door locks. The GEMACM1D can supply a constant combined maximum
12V output of 1.5A for D1-PWR and D2-PWR.
3. Connect Door Contacts. Supervised normally closed
door contacts can be wired in series with a 2.2K end-ofline resistor between terminals 25 and 26 (place the
supervisory resistor in series at the door contact).
4. Additional Accessories.
Optional devices such as a
Request to Exit button, an audible silence button, and a
Request to Arm button are described below.
• A Request to Exit button is mounted inside the se-
cured area and is used to unlock the entry door without requiring a second card reader. The RTE button
is a normally open momentary switch wired between
terminals 27 and 28.
An
•
Audible Silence button
is mounted inside the
secured area and is used to silence the card reader
sounder during door ajar conditions, and kick-in conditions. The Audible Silence button is a momentary
normally open switch wired between terminals 24-25
(SND OFF).
• A Request to Arm button can be mounted inside

or outside the secured area and is used in conjunction with a proximity card (enabled for arming) presented at a card reader. When the RTA button is
pressed, a window of time is created during which a
valid card must be presented to the card reader in
order for arming to take place. This window of time
is equal to six times (6x) the time programmed in the
"Un-Lock" time (see pages 11 and 16) The RTA
button is a normally open momentary switch wired
between terminals 28 and 29. Before arming, the
area to be armed must be secured (all protected
doors closed, all motion sensors stable, etc.).
Note: Consult all installation instructions provided with
each accessory before installation and connection to
the GEM-ACM1D.
5. Connect Card Reader(s). Each GEM-ACM1D can
control one access card reader and two when used with
a GEM-2D module. Card readers can be installed on
one door (to control both entry and exit) or when used
with the GEM-2D on two separate doors (to control access in one direction only). Connect the Card Readers
to the GEM-ACM1D as shown in the table below.
Note: Connecting the power lead of a 5VDC reader to
a 12VDC configured power terminal may damage the
card reader. See "Card Reader Power Jumper" further
in this manual for proper power configuration.
Each ACM will operate with any card reader that trans-
mits data in a Weigand format, regardless of manufacturer. Two card formats are supported: (1) NAPCO
standard 36 bit format or (2) HID standard 26 bit format.
The "embossed" number printed on the face of the
card, up to 6 digits, must be manually entered as the
user code (see Programming pages 12 and 18). When
this embossed number is entered and configured in the
system, the number cannot be entered at a system keypad for access.
Reader LED Indications
Many card readers include an LED for visual feedback
when access cards are presented to the reader. See
Table 3 for the variety of LED indications and their
meanings.

section on page 10 below. When Stealth Mode is
disabled ("normal operation"), the LED's are always
enabled and mimic the Keypad Status LEDs for the
following functions only: Armed, Disarmed, Ready,
Not-Ready and Alarm.
Card Reader Sounder Operation
Many card readers include a sounder for audible feed-
back. The sounder output can be connected to local
warning devices for:
• Access Door Kick-In. Kick-In occurs when a locked
access door is opened (the n/c circuit between terminals 25-26 or 43-44 opens). A "Kick-In" can also occur if either door circuit is shorted while locked (a supervisory resistor should be connected as close to
the door contact as possible, as required for Grade A
installations). The Sounder Out terminals 23 and/or
41 turns active low, and the local sounder activates
and remains active until the access door is closed.
Additionally the "Kick-In" condition will cause the
GEM-X255 connected to the GEM-ACM1D to sense
the zone programmed "Kick-In Zone" as faulted. Depending on the panel program, a faulted "Kick-In
Zone" will generate an alarm or trouble. Typically,
this zone would be programmed for 24-hour and Burglary output. The panel will continue to sense this
zone as open until the door contact is restored.
Door Ajar. The access door is open for 30 seconds
•
or longer. The local sounder activates and remains
active until the door is closed.
A "Door Ajar" condition causes the GEM-ACM1D to
turn the (-) SND OUT (terminal 23) active low. Typically, this activates the card reader sounder. A remote low current sounder may be wired to the SND
OUT and (+) READER PWR (terminal 17), but be
aware that the sounder will activate whenever the
GEM-ACM1D uses the SND OUT terminal to generate sounds on the card reader (valid card, RTE button press, first swipe of double swipe arm, etc.). The
SND OUT will remain on until the door is closed or
until the SND OFF button is pressed. (The SND OFF
button is a N/O momentary push button wired to terminals 24 and 25 of the GEM-ACM1D).
Additionally the "Door Ajar" condition will cause the
GEM-X255 connected to the GEM-ACM1D to sense
the zone programmed "Door Ajar Zone" as faulted.
Depending on the panel program, a faulted "Door
Ajar Zone" will generate an alarm or trouble. The
panel will continue to sense this zone as open until

the door contact is restored.
6. Other Connections and Jumpers
Card Reader Power Jumper (JP1). Determine the
power requirements of the card reader in use and connect jumper JP1 as follows: If a 12V device, place the
jumper on the top two pins (pins 1 and 2) and if a 5V
device, place jumper on the middle and bottom pins
(pins 2 and 3). Note: Jumper set to 12V from factory.
See wiring diagram for details.
Keypad Address Jumper (JP2)
. Notice that JP2 has
5 pairs of pins, each pair forming a vertical "column".
For JP2, the Access reader uses a keypad location in
the system for communication (Keypad #1 must NOT
be selected as an ACM type). The JP2 pin "columns"
1-4 must reflect (in hexadecimal) the keypad/ACM address to be selected in the panel programming. Therefore, if keypad address 2 is to be used for the ACM in
panel programming, the shunt connector should be
placed on the second "column" of pins marked "2" in
JP2. If keypad address 3 is to be used, place jumpers
on the first and second "column" of pins marked "1" and
SECOND DOOR INSTALLATIONS
"2". See Fig. 3 and Table 4 below for jumper placement. Note: Panel programming is to be performed
later, in the section below "Panel Programming". Pins
marked "5" are used for the high security "Degrade
Mode Off Jumper", see next section below.

High Security--Degrade Mode Off Jumper (JP2 Pins
#5). This pair of pins on the far right (5th "column") de-
termines the operation of the GEM-ACM1D module
when a bad checksum computation is encountered.
From the factory, JP2's fifth "column" of pins are unpopulated, and therefore provides a lower security level
for the system as follows:
When the GEM-ACM1D detects a bad configuration
•
data checksum computation and loses communication with the panel (unable to receive an update), the
GEM-ACM1D will grant access to any user who has
a SIA 26-bit Standard card or a NAPCO proprietary
36-bit card.
If higher security is desired, fifth "column" of pins in JP2
can be shorted using shunt provided and the GEMACM1D will not allow access.
Door Lock Power - Battery Backup Jumper
. Placing
a shunt connector on jumper JP3 (factory default) enables battery power backup for the D1 PWR and D2
PWR outputs. Jumper JP3 will not affect the battery
standby operation of all other terminals on the GEMACM1D. Therefore if AC power is lost, the GEMACM1D will continue to function, but doors will not be
powered unless powered by a separate circuit. When
this jumper is not installed, the GEM-ACM1D fulfills the
UL 4 Hour Standby requirement (and is allowed to remain a UL listed mercantile burglary accessory to the
GEM-X255) even when drawing the maximum rated
current (1.5A) from the door locking mechanism power,
with the 4 amp-hour battery connected. If jumper is installed and AC is lost, doors will be powered by the battery, but batteries may be discharged quickly if the door
locking mechanism requires power to operate. See the
Standby Battery Calculation Worksheet on page 8.
SECOND DOOR INSTALLATIONS
The GEM-2D is a module that connects to the GEMACM1D. It allows the GEM-ACM1D to independently control a second access relay using a separate card reader.
The GEM-2D is basically identical to the GEM-ACM1D,
except that the GEM-2D uses separately wired card readers, door contacts and locking device relays that all function in the same manner as the GEM-ACM1D. In addition,
readers connected to the GEM-2D do not provide Arm/
Disarm capability. See "Typical Installations", Options 1
and 2 on page 2.
Installing the GEM-2D
When connecting the GEM-2D to the GEM-ACM1D, insert
the pins of the GEM-2D into receptacles J4F and J5F located on top of the GEM-ACM1D. Before inserting, align
all pins and receptacle sockets, then fully insert the GEM2D into the GEM-ACM1D. See Fig. 4 below illustrating the
installation of the GEM-2D into the GEM-ACM1D.

GEM-2D WIRING/CONFIGURATION
Connect 2nd Door Strike (Mag Lock).
NOTE: Before installation, always check with local
laws having jurisdiction concerning the installation of
magnetic locking devices. There may be strict limitations with regard the installation of magnetic or similar
exit door locking devices. Local laws may require the
installation of electrically separate panic hardware to
ensure the door can be opened in the event of an
emergency.
Door strike outputs are controlled by schedules pro-
grammed into the panel. These door strike outputs can
operate DC-powered locking devices such as magnetic
door locks or other electromechanical locks and can be
configured to operate in "Fail Secure" (which remain
locked when power fails) or "Fail Safe" (which unlock
when power fails) configurations.
For normally closed door strikes, connect ground to ter-
minal 6, wire terminal 5 to terminal 32, then connect the
positive door strike wire to terminal 34. See Figs. 5 and
6 below. The GEM-ACM1D can supply a constant
combined maximum 12V output of 1.5A for D1-PWR
and D2-PWR.

STANDBY-BATTERY CALCULATION WORKSHEET
Use the procedure given below to determine the required standby battery capacity in Ampere-Hours (AH). NOTE: It is not totally
accurate to merely divide the combined standby current (in amperes) by the battery amp-hour rating to obtain the standby time (in
hours), since other factors (control-panel charging capabilities, temperature, battery condition, battery discharge rate, etc.) affect
battery operation. The following calculations will yield the theoretical standby time of the 4AH and 7AH batteries at room temperature. NOTE: JP3 is used to provide standby power to D1 and D2 power output terminals. When AC power is removed, these terminals will not have battery standby voltage available. UL has only evaluated the system with JP3 removed. In addition, this
Standby-Battery Chart has not been evaluated by UL.
