NAPCO GEMC-WL-WD2 User manual

1
GENERAL DESCRIPTION
The GEMC-WL-WD2 is a 2-point window/door transmitter designed
for use in Napco Gemini C-Series wireless systems, and with Napco's
GEMC-RECV series wireless receivers (see WI1682). When used
with the supplied magnet, the transmitter functions as a window/door
sensor. Terminals are provided for supervised external contacts so
that one or more additional contacts may be used in conjunction with,
or instead of, the internal reed switch. A jumper (J1) allows the use of
external contacts (such as UL Listed door/window magnets or ball
contacts, fire alarm pull stations, thermal detectors, waterflow tamper
switches, etc.), instead of the internal reed switch within the same
room (maximum 20' wire length for Burglary installations, maximum 3'
wire length for Fire installations*; 22-18AWG) for Fire and Burglary
sensors. In addition, the GEMC-WL-WD2 includes a rear tamper to
protect against the removal of the transmitter from the wall.
The GEMC-WL-WD2 is powered by a 3-volt lithium battery that will
power the transmitter for up to 5 years. When battery voltage drops
below normal, a low-battery report will be sent to the receiver (replace
battery with a Duracell 3V lithium battery DL123A, Varta/Power-One
model CR123A or Panasonic CR123A only; use of another battery
may present a risk of fire or explosion).
Each transmitter has a unique factory-programmed code (printed on
the battery holder and also on the rear case) that distinguishes itself to
the receiver. (Note: See control-panel instructions for entering this
six-digit hexadecimal code and its checksum digit into the panel; be
sure to enter all numbers and/or letters, including leading zeros, if
any).
Note: When connected for use with a Fire system, and a fire condi-
tion sends a fire alarm signal, this signal will be sent until the condition
clears.

INSTALLATION
Note: The transmitter and magnet may be mounted in any position
with no degradation in performance. Thus, if a left-handed reed
switch is required, the unit may be mounted upside down. However,
for reference purposes in this text, the transmitter will be considered
oriented with the antenna at the top, as shown in these illustrations.
1. Remove the cover. Remove the GEMC-WL-WD2 transmitter
cover by inserting a small screwdriver into the slot at the bottom
and twisting while applying upward pressure. See Fig. 2 below.
2. Insert the battery. Observe battery polarity. Insert battery with
positive (+) terminal toward terminal block. See Fig. 3. The
battery will not make contact if inserted backwards.
3. Identify transmitter parts. Refer to Fig. 4.
4. Select transmitter location. Avoid mounting the transmitter near
the floor. Low level mounting can reduce transmission range and
may subject the transmitter to damage.
5. Remove transmitter and magnet mounting plates.
Transmitter: Use a small screwdriver to push in retaining tab (Fig.
6) and slide cover upward. Magnet: Insert small screw driver into
slot at either end of magnet cover. Push in and twist to pop off
cover. If using external contacts, skip to Step 7.
6. Attach mounting plates. Note: While use of the transmitter
mounting plate is recommended, mounting holes in the rear case
allow mounting without the plate. Use #6 flat-head screws to affix
the mounting plates, observing alignment marks shown in Fig. 6.
Mount the magnet within ½" from the transmitter. Place the tam-
per spring that emerges from the transmitter rear cover into the
top of the oval hole in the transmitter mounting plate. Move the
transmitter down until it snaps onto its mounting plate; snap the
magnet onto its mounting plate. For internal contacts, skip to Step
9.
7. (For external contacts only). Install contact or sensor and
transmitter mounting plate (if used). Mount the external contact or
sensor as described in its instructions. For recessed wiring, drill
an access hole for the wire.
8. (For external contacts only). Connect to terminals. Connect
two wires from an external sensor having normally-closed
contacts (or a normally-closed loop) to Point-1 (Terminals 1–2).
Similarly, if required, connect a sensor (or loop) to Point-2
(Terminals 2–3).
9. Complete transmitter setup. Install Jumper J2 (see Fig. 4) to
enable the holdoff timer (after triggering, unit waits 3 minutes
before retriggering). For example, if used on doors in heavy traffic
areas, this will prevent multiple alarms and thus conserve battery
life. Note: If J2 is installed, both points will be delayed 3 minutes
before retriggering. If internal reed switch is used, remove Jumper
J1 (see Fig. 4) and short Point-1 (Terminals 1–2). An external
contact may be connected to point 2.
10. Close the transmitter case. Close the case by engaging the
hooks at the top, then snap the bottom together.
11. Program the panel. Enter (a) the zone number to which the
transmitter will be mapped; (b) the 6-digit ID code with checksum
digit; and (c) the wireless point number. Refer to the programming
instructions for the control panel and keypad in use. Note: In UL
burglary installations, program the burglary alarm output for all
protective devices.

WIRING
The GEMC-WL-WD2 may be wired in any of the following configurations; refer to the diagrams below: Note: For Commercial and Resi-
dential Fire installations, only ONE initiating device may be connected to this transmitter (only normally open contacts used for Fire). For
Commercial Burglary installations, multiple initiating devices may be used as long as the devices all serve the same function (i.e. door, win-
dow, motion, etc.).
Notes: 1. Caution: Changes or Modifications not approved by Napco may void the user's authority to operate the equipment.
2. This device may not cause interference.
3. This device must accept any interference, including interference that may cause undesired operation of the device.
4. Only loop 1 is supervised.

To terminate more than two conductors or
conductors of different wire sizes to a terminal,
use the "pigtail" type wiring method as shown at
right. Use insulated wire for the pigtail, and firmly
secure the conductors to the pigtail using an ap-
propriate wire nut or crimp connector for the num-
ber and gauge of conductors used.
