PENDANT TRANSMITTERS Installation Instructions
,1752'8&7,21
The WT-201 is a series of miniature transmitters, designed to
send coded transmissions to wireless receivers of the WR-200
and WR-300 series. Transmission is activated by depressing the
recessed pushbutton at the center of the unit. Transmitters with
an A-suffix are equipped with a 4-channel selector. The
WT-201WP is a waterproof version of the WT-201.
All WT-201 units are supplied with the chain installed, to be worn
around the neck as a pendant transmitter. A key ring is also
included in the package, for use in place of the chain. Operating
power is obtained from a cylindrical 12-volt alkaline battery
(Duracell MN-21, Golden Power GP-23A or equivalent).
A LED lights during transmission, indicating the battery voltage
condition (lights when battery voltage exceeds 8 VDC). If the LED
does not light during transmission, the battery must be replaced
immediately.

A. WT-201 and WT-201A
(1) Insert an 1/8 inch screwdriver blade in the slot at the bottom of
the case, and follow the steps shown in Figure 2.
Warning! Do not open the case by inserting a screwdriver in
places other than the slot. This can damage the transmitter.
Figure 2. Opening the Case
(2) Insert the 12-volt alkaline battery (Duracell MN-21 or Golden
Power GP-23A or equivalent) between the battery clips, so
that the (+) and (–) markings on the battery coincide with the
markings near each battery clip - see Figure 1. Check that the
battery is held securely by the battery clips.
(3) Gently press the pushbutton switch and verify that the LED
lights, indicating good battery condition.
(4) Carefully engage the ridges at the top end of the rear cover
with the dents at the top end of the front cover. Gently press
together the bottom ends of both covers, until they snap shut.
B. Waterproof Version WT-201WP 
Waterproof units are shipped fully assembled but not closed, to
permit insertion of the battery before final sealing. The case is
made waterproof when its two halves are assembled and secured
together with 4 screws. To prepare the unit for use:
(1) Separate the two halves of the case and lay the unit down on
its back as shown in Figure 3. Insert the 12V battery between
the battery clips. Observe polarity!
(3) Gently press the pushbutton switch and verify that the LED
lights, indicating good battery condition.
(4) Reassemble the two halves of the case and lay the unit face
down. Put a screw in each of the four holes on the back
(screws are supplied in a small bag packed with the unit).
Carefully tighten all 4 screws with phillips screwdriver No. 1.
The unit should now be watertight and ready for use.

All WT-201 units have an
8-key DIP switch (marked 1 to
8). Each switch may be set to
ON or OFF position, to create
a unique digital system code -
see Figure 4.
Figure 4. Code Selector
Use a ball point pen to set each of the switches to match the
code setting of the companion receiver.
CAUTION: The factory test code (2, 4, 5, 6, 7 ON / 1, 3, 8 OFF)
must not be used. Also avoid codes which are often OFF or
alternating ON/OFF used: all keys ON, all keys settings.

Model WT-201A is equipped
with a 4-channel selector
marked CHAN (see Figure 5).
Using this switch you can set
the transmitter for activating
one of four outputs at the
receiver. This feature is
important for zoning purposes
Figure 5. Channel Selector
- activating different alarm zones of a control panel via a
companion, multi-channel receiver. The channel data transmitted
by the WT-201A is selected by positioning the 4 switches in
accordance with the required channel number. Use a ball point
pen to set the channel selector as required by the host system.

A. Stand 10 feet away from the receiver and operate the
transmitter.
B. Verify that the transmitter LED lights, indicating good battery
condition.
C. Observe that the receiver LED lights, indicating detection of
the transmitted RF signal.
D. Verify activation of the receiver's output relay associated with
the channel selected in the transmitter (the WT-201
single-channel transmitter operates the relay associated with
channel 1).
E. Operate the transmitter from various locations within the area
covered by the receiver to determine "dead" locations, where
transmission is obstructed by walls and large objects, or
affected by structural materials.

A. Remove the chain by opening and
slipping it through the triangle on
top of the WT-201.
B. Insert the tip of a long-nose pliers
into the triangle and open it.
C. Remove the triangle.
D. Open the plastic bag which
contains the key-ring kit.
E. Slip the key-ring triangle through
the last link of the key-ring chain
and install the triangle into the
hole on the top of the WT-201
(Figure 6).

Our wireless systems are very reliable and are tested to high
standards. However, due to their low transmitting power (required
by FCC regulations) there are some limitations to be considered:
A. Receivers may be blocked by radio signals occurring on or
near their operating frequencies, regardless of the code
selected.
B. A receiver can respond to one transmitted signal at a time.
C. Wireless equipment should be tested regularly (at least once
a week) to determine if there are sources of interference and
to protect against faults.
