GEM-P816 Installation Instructions
INTRODUCTION
GENERAL DESCRIPTION
Napco's Gemini GEM-P816 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 16 zones with the use of optional zone expansion
modules, wireless receiver modules and/or GEM-RP1CAe2/GEM-K1CA Keypads. Each panel includes an integral
digital communicator.
Opening Suppression and Closing Suppression, available through Napco Quickloader software, suppress reporting
within programmed “windows”. Conversely, Exception Reporting can transmit a “fail to close” if the panel is not armed
within programmed intervals and, similarly, a “fail to open” if the panel is not disarmed within programmed intervals.
Furthermore, the panel can be programmed to automatically arm either area at any time. A log containing up to 400
events (accessible through QuickloaderTM 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 status
messages, and the log can also be viewed. 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 the 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 16 user codes and custom zone descriptions.

INSTALLATION
MOUNTING
Control Panel
Choose a mounting location accessible to (a) a continuously-powered AC source, (b) system ground, a steel or
copper ground rod, ideally no further away than 10 feet, and (c) telephone lines (keep telephone wiring away from
keypad wires). Remove appropriate knockouts for cables. Place the control panel at a convenient viewing height
and mark the mounting holes. Attach the enclosure using screws suitable for the mounting surface.
Grounding
Connect the control-panel grounding screw to a metal cold-water pipe or a long steel (or copper) ground rod driven
deeply into the earth. Do not use a gas pipe, plastic pipe or AC ground connections. Use at least 16-gauge wire.
Make the run as short and direct as possible, without any sharp bends in the wire.
Keypad
A keypad should be located near each exit/entry door. The keypad features a handy pull-up reference label.
Before mounting the keypad onto the wall, push the Sliding Label Plate (with label and felt backing affixed and
handle facing forward) down the guides at the rear of the keypad until it snaps into place. Once installed, the
Sliding Label Plate cannot be removed without first removing the keypad from the wall. Note: (1) The keypad fire
and panic keys should not be considered a substitute for a listed manual initiating device, such as a pull box. (2)
Each GEM-RP1CAe2 includes provisions for four additional zones. See ADDING EXPANSION ZONES.
If installing onto a double-gang box, insert mounting screws through the two vertical elongated holes on the left
side of the case and into the box. If the box is visible when viewed from the front, adjust the keypad vertically and
tighten the screws. Then, using hardware suitable for the mounting surface, add one or two screws at the right
side of the keypad case directly into the wall to ensure a secure installation. Note: Do not overtighten the screws!
Uneven walls may cause the keypad case to distort.
CAUTION: This equipment generates and uses radio-frequency energy. If not installed using conventional installation
practices for RF devices, it may cause interference to radio and television reception. It has been tested and found to
comply with the limits for a Class A computing device pursuant to Subpart B of Part 15 of FCC Rules, which are
designed to provide reasonable protection against such interference. However, there is no guarantee that
interference will not occur in a particular installation. If it has been found to cause interference to radio or television
reception, which can be determined by removing and reapplying AC and battery power to the equipment, the installer
should try to correct the interference by one or more of the following measures: reorient the receiving antenna;
connect the power transformer to a different outlet so that the control panel and receiver are on different branch
circuits; relocate the control panel with respect to the receiver.

GEM-P816 Installation Instructions
Wiring
Wire keypad(s), zones, expansion zone modules and output devices as shown on the Wiring Diagram. Note that the
Wiring Diagram contains important information not available elsewhere in this manual.
Adding Expansion Zones
GEM-P816 control panel can support up to 16 zones as is, however this number may be increased to as many as 16
programmable zones using optional expansion zone modules (EZMs).
Wireless Systems
With the addition of at least one GEM-RECV series receiver, the GEM-P816 will support up to 16 wireless transmitters.
The panel can accommodate one or two receivers within the premises, responding to the one with the stronger
transmitter signal. If any transmitters are selected for the default program, a GEM-RECV receiver will automatically be
programmed.
The keypad can display the status of any transmitter, indicating the condition of the zone (normal or open) and
transmitter troubles (low battery, tamper or supervisory failure), and signal strength of the last transmission. A receiver
failure will be indicated by “E06-NN” (“no response”, with NN representing the receiver number).
TYPICAL RESIDENTIAL FIRE INSTALLATION (Where permitted by local codes)
At least one smoke detector should be installed directly outside
each sleeping area. If there is more than one floor, additional
smoke detectors should be installed on each level, including the
basement. The living-area and basement smoke detectors
should be installed near the stairway of the next upper level.
For increased protection, additional detectors should be installed
in areas other than those required, such as the dining room,
bedrooms, utility room, furnace room, and hallways. Heat
detectors, rather than smoke detectors, are recommended in
kitchens, attics, and garages due to conditions that may result in
false alarms and improper operation. Large areas and areas with
partitions, ceiling beams, doorways, and open joists will require
additional detectors.
Refer to NFPA Standard No. 74 (National Fire Protection
Association, Batterymarch Park, Quincy, MA 02269) for
additional information, including proper mounting of detectors.
CAUTION: Do not run telephone wiring near speaker wires; do not run keypad wiring with loop wiring.

TESTING THE SYSTEM
After installation is completed, test the system as follows.
1. Call the central station to inform them of the test.
2. Initiate an alarm, preferably on a zone that activates a steady siren, and verify proper signalling.
3. Call the central station to confirm their receipt of a good transmission.
Note: Be sure to test all enabled keypad panics.
Signal Strength Testing/Wireless Systems
To test the operation of wireless transmitters, proceed as follows.
1. Enter the Fault-Find Mode. (See Dealer Mode on page 52. Panel must be disarmed).
2. Fault a point of the transmitter to be tested by opening the loop. If the signal strength of the transmitter is 3 or
greater, the keypad will beep, as follows:
3. Restore the wireless point (close the loop).
The transmitter signal strength will be displayed on a scale of 3-10 with 3 considered marginal and 10
considered excellent. Note that if the signal strength is less than 3, the keypad will not beep and the strength
will not be displayed. Except in the Fault-Find Mode, signal strengths less than 3 will be entered into the
system log. Upon zone restore, the keypad will beep once.

KEYPAD CONFIGURATION MODE
This section will focus on configuring the GEM-RP1CAe2/GEM-K1CA and GEM-RP2ASe2/GEM-K2AS Keypads. We recommend
that either a GEM-RP1CAe2 or a GEM-K1CA keypad be used for programming.
KEYPAD INSTALLATION
Each keypad must be assigned an address number (1–7) and each requires its own configuration procedure (see CONFIGURING
THE KEYPADS, which follows, and DIRECT ADDRESS KEYPAD AREA OPTIONS). At least 1 keypad must be used; only 1 is
required for a single-area Commercial Burglary installation.
•GEM-RP1CAe2/GEM-K1CA - is a 2-line combination fire/burglary/access keypad capable of supporting 4 EZM zones. A GEM-
RP1CAe2 or GEM-K1CA is recommended for use with programming.
•GEM-RP2ASe2/GEM-K2AS - is a utility LCD keypad combining several preset LCD words with a limited message line. NOTE:
Due to space constraints, available messages are abbreviated and will scroll automatically.
CONFIGURING THE KEYPADS
A total of up to 7 keypads may be connected to the panel. GEM-RP1CAe2/GEM-K1CA and GEM-RP2ASe2/GEM-K2AS keypads may
be intermixed but require different configuration procedures, as described in the following paragraphs. If you have a GEM-K1CA key-
pad, please see the "Important Note" on page 5 regarding the differences between the GEM-RP1CAe2 and the GEM-K1CA keypad
buttons. The buttons displayed below will be for the GEM-K1CA keypad.
Configuring the GEM-RP1CAe2/GEM-K1CA Keypad
Each GEM-RP1CAe2/GEM-K1CA keypad must be configured for (a) keypad tactile beep; (b) entry
sounder; (c) keypad address; (d) EZM address; and (e) zone response.
To enter the GEM-RP1CAe2/GEM-K1CA Configuration Mode:

GEM-P816 Installation Instructions
BASIC OPERATION
This section provides a brief overview of system operation. For detailed operation, refer to the User's Guide furnished
with the keypad (see page 7 for a listing of User Guides for each keypad) and to the Keypad Programming Modes at
the end of this manual. NOTE: Keypad displays shown in this text are for the GEM-RP1CAe2/GEM-K1CA keypads.
GEM-RP2ASe2/GEM-K2AS displays will be similar, although abbreviated, and will scroll automatically.
USER CODES & ZONE DESCRIPTIONS
(Refer to the GEM-P816 Programming Instructions (WI995 and WI1182) for a detailed explanation of programming).
Up to 16 personal user codes may be programmed at the keypad. NOTE: The Area Options associated with each
User Code may only be programmed in the Dealer Program Mode.
Default User Code.
The first code programmed should replace the default (User 01) code, “U01 123 • • • - • • - • • ”, (1,2,3), which should
not be selected as a user code.
Each user should be assigned his own dissimilar code and should be cautioned against divulging his code to anyone
else. Thus should it become necessary to remove a user from the system, that one code may be cancelled without
affecting other codes, and that user would then be prevented from entry. Note: Duplicate User Codes are not allowed
by the panel; therefore a duplicate Code entered in the LCD Window will erase when Uis pressed.
Changing or Canceling a User Code
To change any user code, merely program over the existing user code as described in the Programming Instructions.
Similarly, to cancel a user code, blank out each number of the user code.
Arm/Disarm Code (Programmable in Dealer Program Mode only)
An Arm/Disarm Code may be used to arm/disarm the area in which it is programmed. Up to 6 digits may be
programmed or it may be programmed as a two-digit code for the purposes of arming quickly.
Arm-Only Code (Programmable in Dealer Program Mode only)
An Arm-Only Code may only be used to arm the area in which it is programmed; it never has any disarm capability.
Up to 6 digits may be programmed or it may be programmed as a two-digit code for the purposes of arming quickly.
Service Code (Programmable in Dealer Program Mode only)
A Service Code is an Arm/Disarm Code that is easily activated when needed, and dormant at other times. Intended
for the occasional or temporary user (repairman, etc.) who would otherwise be denied access to the premises. It may
then be used to arm and disarm just as any other User Code. A Service Code can be armed/disarmed from a
disarmed state, but it cannot be armed/disarmed from an armed state, after another user code has been entered. Up
to 6 digits may be programmed or it may be programmed as a two-digit code for the purposes of quicker arming.
Access Code
The Access Code will trip the panel's PGM2 Output Relay while armed or disarmed if the “Access Control on PGM2
Output” and “PGM2 Output Access Control Time” is programmed. The Access Code is programmed as any other user
code, but without arm/disarm capability. Note: These systems have not been investigated by UL for compliance with
UL294 (Access Control Systems).
Ambush Code
The Ambush Code is special user code entered by the user typically to cause a silent report to be sent to the central
station. Thus, should the user be forced to disarm by an assailant, he can silently signal an emergency while
appearing to be merely disarming the panel. (Check the glossary for programming required to enable this feature).
Zone Descriptions (GEM-RP1CAe2/GEM-K1CA only)
Zone descriptions follow the Program Code in the normal programming sequence. Program the description, up to two
lines, letter by letter. Enter an identifying description for each zone. Characters are selected by pressing keypad but-
tons multiple times, "Cell Phone" style. Buttons 1through 9plus 0and Gare used. Press Rto
move cursor right, press [B] to move cursor left.
To advance to the next zone (or to any other zone), move the cursor to the displayed zone number (i.e., “01”) using
