GENERAL DESCRIPTION
The GEM-ACM1D is an accessory that adds integrated
access control to the burglary alarm functions of the GEM-
X255 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 bur-
glary 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 dis-
played as a
KEYPAD/ACM TROUBLE
at the other keypads.
Any ACM tampers will be displayed as a
KEYPAD/ACM
TAMPER
at the other keypads. GEM-X255 panel code ver-
sion 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 Sched-
uler (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.
Note:
Be aware that more than one event can be
assigned to each user, and the total number of events al-
lowed is always limited to 255 regardless of how many us-
ers are programmed.
The GEM-ACM1D requires the panel for uploading user
codes/attributes (and their associated schedules), upload-
ing 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, in-
cluding the Polaris XYZ magnetic card reader, the Shad-
owProx proximity card reader, the HID proximity readers,
and the 26-bit standard Wiegand card readers. The GEM-
ACM1D also supports the use of any "Request to Exit" de-
vice, including the T-Rex exit detector.
* UL installations require JP3 to be removed.
** Not Evaluated by UL.
*** Requires GEM-2D to be installed.
