PENDANT TRANSMITTERS
,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 . Transmissi on is activat ed by depressing the
recessed pushbutton at the cent er of the unit. Transmitters with
an A-suffix are equipped with a 4-channel selector. The
WT-201WP is a water proof version of the WT-201.
All WT-201 unit s ar e s uppli ed wit h t he chai n i nst all ed, to be wor n
around the neck as a pendant transmitter. A key ring is also
included in the package, for use in pl ace of the chain. Oper ating
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 batt ery vol tage exceeds 8 VDC) . If the LED
does not light during transmis sion, the battery must be r eplaced
immediately.

the case, and follow the steps shown in Figure 2.
Warning! Do not open the case by insert ing a screwdriver in
places other than the slot. This can damage the transmitter.

together the bottom ends of both covers, until they snap shut.
B. Waterproof Version WT-201WP
Waterpr oof units are shipped fully as sembled 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:
Separate the two halves of the cas e and lay t he unit down on

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 watert ight and ready for use.

All WT-201 units have an
8-key DIP switch (mar ked 1 to
8). Each switch may be set t o
ON or OFF position, to c reate
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 tes t 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 sett ings.

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

- activating different alarm zones of a control panel via a
companion, multi-c hannel receiver. The channel dat a transmi tted
by the WT-201A is selected by positioning the 4 switches in
accordance with the r equired channel number. Use a ball point
pen to set the channel selector as r equired by the host sys tem.

A. Stand 10 feet away from the receiver and operate the
transmitter.
B. Verify t hat the transmitter LED l ights, indicating good battery
condition.
C. Observe that the receiver LED li ghts, indicating detection of
the transmitted RF signal.
D. Verify activation of the rec eiver's output relay assoc iated with
the channel selected in the transmitter (the WT-201
single-channel tr ansmitter operates the relay as sociated 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.

Our wireless systems are very reliable and are tested to high
standards. However, due to t heir low t rans mi tt ing power ( r equir ed
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 t ested regularly (at l east once
a week) to determine if there are s ources of inter ference and
to protect against faults.
