Napco GEMTRANS2 Gemini 2-Point Wireless TransmitterGEM-TRANS2 2-Points
Installation Instructions
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.
• Soft white - (GEM-TRANS2 & GEM-TRANS4) or brown compact and low profile
• Reversible mounting position for left or right handed operation
• Low battery clearly displayed at keypad by zone # and transmitter #
• GEM-TRANS4 is most economical. 4 adjacent auxiliary devices can be simply
piggybacked off TRANS4's integral four-point terminal block (ex. - a bank of windows -
etc.).
• All models include: built-in reed switch magnet - battery - tamper and terminals.
Can Do N/c Or N/O Contacts
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 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
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.
