NAPCO GEM-TRANS2 User manual

GENERAL DESCRIPTION
The GEM-TRANS2 is a 2-point window/door transmitter designed for use in Napco GEM-series wireless systems. When used with the
supplied magnet, the transmitter functions as a window/door sensor. However, terminals are provided for normally-closed external
contacts so that one or two additional devices may be used in conjunction with, or instead of, the internal reed switch. A jumper option
is provided to allow a normally-open external contact to be used. This allows the use of one external contact instead of the internal
reed switch. The GEM-TRANS2 is powered by a 3-volt Type DL123A lithium
battery, which 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.
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.)
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 consid-
ered oriented with the antenna at the top, as shown in these
illustrations.
1. Remove the cover. Remove the GEM-TRANS2 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. Choose a location for the transmitter.
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 ” from the transmitter. Snap transmitter and magnet onto their mounting plates. 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 thereby 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 con-
nected 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.
