INTRODUCTION
GENERAL DESCRIPTION
NAPCO's Gemini GEM-X255 is a state-of-the-art microcomputer-based burglary and residential fire alarm control panel
of modular design. Integrally an 8-zone panel, it will support up to 255 zones with optional zone expansion modules,
wireless receiver modules and/or GEM-RP1CAe2/GEM-K1CA Keypads. Each panel includes an integral digital commu-
nicator.
The control panel features programmable area partitioning. That is, the system may be divided into up to 8 discrete mul-
tiple-zone areas, each allowing access by only those users programmed for their respective area(s).
Opening Suppression and Closing Suppression, available through Napco Quickloader software, suppress reporting
within programmed “windows of time”. Conversely, Exception Reporting can transmit a “fail to close report” if the panel
is not armed within programmed intervals and, similarly, a “fail to open report” if the panel is not disarmed within pro-
grammed intervals of time. Furthermore, the panel can be programmed to automatically arm either area at any time. A
log containing up to 800 events (accessible through Quickloader
TM
software) monitors control-panel activity referenced to
a precision real-time clock. A detailed event history may be displayed at the computer, using NAPCO's PCD-Windows
Quickloader Software.
Keypads feature a liquid-crystal display for messages. In normal use, the LCD shows zone identification and system
status messages. Conventional LEDs and a sounder are also provided for annunciation.
Data may be quickly and easily downloaded to the control panel using a PC-compatible computer with NAPCO's PCD-
Windows Quickloader software and PCI2000 computer interface. Or, the panel may be programmed using the keypad in
its secondary mode of operation. In keypad programming modes (there are two: Dealer and User), the LCD shows
memory address, data values, programming prompts, and the alphanumeric characters required for entering up to 195
user codes and custom zone descriptions.
GEM-X255M
The standard GEM-X255 may be converted to the Mercantile “GEM-X255M” version with the optional H1217 accessory.
The H1217 kit includes the model H217 heavy-duty UL commercial enclosure, two tamper switches and tamper screws.
Note:
Do not use Fire Zones in a Mercantile installation.
