Cut Sheet

PRELIMINARY SPECIFICATIONS:
The GeminiAccess System supports HID standard 26 bit
format and/or NAPCO Gemini Prox format.
Recommended prox readers:
• HID Prox Point Plus Model 6005B
• NAPCO GEM-PX Prox Reader with Alarm Status LEDs
The GEM-ACM1D also supports the use of any “Request to
Exit” device and any UL 294 listed mag lock.
GEM-PX Prox Reader with Alarm Status Indicators
The unique GEM-PX Prox Reader includes LED status
indicators for both the access and alarm system The LED’s
function as follows:
• RED – Displays System Armed (on solid), system disarmed,
(off) and system in alarm (blinking).
• GREEN – Displays Ready to Arm (on solid), not ready (off).
(Note: Alarm Status indication is a programmable option by Module and may be
eliminated in undesirable instances, for example, where the reader is visible from outside
the premises, etc.)
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 readers and to recharge the
battery. The panel and 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 electromagnetic 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 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. 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.
Fire System Integration
GeminiAccess includes an “Emergency Free Access” zone
for integration with a fire system. 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. (Before installing
the access control system, be sure to consult with the authority
having jurisdiction to be sure to comply with all local codes.)

Typical Applications:
App. Example 1 – uses a single prox reader on the exterior of the
restricted area and a “Request to Exit” button within the restricted
area. This method only requires a single reader for each access
door. This method is limited in that only entrance via the card reader
is logged or printed (requires GEM-PRINT module). The use of the
“Request to Exit” button is not logged.
App. Example 2 – uses 2 prox 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. Each
presentation of the credential is logged and optionally printed
(requiring GEM-PRINT module on the system).
