GENERAL DESCRIPTION
The GEM-2D is a module that connects to the GEM-
ACM1D, an accessory that adds integrated access control
to the burglary alarm functions of the GEM-X255 control
panel. The GEM-ACM1D 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. The GEM-2D allows the GEM-ACM1D to
independently control a second access relay using a separate card reader. For a full description of the GEM-ACM1D,
see WI1221.
Two readers can be used to control one door. Each reader
can be programmed to allow its own independent access
schedules to control both exit and entry permissions for a
single door.
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.
Readers connected to the GEM-2D do not provide
Note:
Arm/Disarm capability.
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

must be used for GEM-ACM1D module installations.
Although the GEM-ACM1D and the GEM-2D perform 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 Quickloader download software) 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. Note:

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 26bit standard Wiegand card readers. The GEM-ACM1D also
supports the use of any "Request to Exit" device, including
the T-Rex exit detector.

POWER SUPPLY
The integral power supply 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. 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 re-connected 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.
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.
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 GEM-2D
Figure 1: Installing the GEM-2D. Before inserting, align all pins and
receptacle sockets, then fully insert the GEM-2D into receptacles J4F
and J5F located on top of the GEM-ACM1D.
into the GEM-ACM1D. See Figure 1 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 4, wire terminal 3 to terminal 14, then connect the
positive door strike wire to terminal 16. See Figs. 2 and
3 below. The GEM-ACM1D can supply a constant combined maximum 12V output of 1.5A for D1-PWR and
D2-PWR.
