1111. INTRODUCTION

. INTRODUCTION. INTRODUCTION

. INTRODUCTION

The WT-100 and WT-100A are general purpose, battery powered single-input
transmitters for use with Normally Open (N.O.) and Normally Closed (N.C.) sensors
and inertial vibration detectors.

A reed switch built into both units can be used with a magnet (not supplied) to protect a
door or a window. An on-board tamper switch triggers a tamper alert (Channel 2) if the
front cover is removed from the base.

A special timing circuit saves the 9-volt battery power by limiting the transmitting time.
When the WT-100 is triggered, it transmits for about 2 seconds, then inhibits itself for
approximately one minute. If an input remains disturbed, the WT-100 will keep
transmitting signals for a 2-second duration each minute, until the input reverts to the
undisturbed state. The WT-100A is a single-shot (non-repeating) model that transmits
only once upon each input trigger.

The LED lights during the transmission period. A special circuit continuously monitors
the battery voltage. If this drops below about 7.5 Volts, the transmitter automatically
transmits a low battery alert signal for 1-2 seconds, to activate a buzzer in the target
receiver. Low battery signals are repeated at one-minute intervals for a few days,
depending on the remaining amount of battery energy. The LED lights during each
transmission, identifying the unit transmitting the low battery signal.

3.1 Mounting

Open the case by removing
the screw from the front cover.
Mount the base with the
printed circuit board in the
selected location, using the
mounting knockouts.

Figure 2. Front Cover Removal

Be sure to mount the unit with the antenna wire hanging down.
Route the wiring through any wiring knockout in the base.

3.2 System Code Selection

!

The on-board CODE selector consists of an 8-position DIP switch
with keys marked from 1 to 8 (see Fig. 3). Each key is set to
either ON or OFF to create a unique digital code (256 possible
combinations). This code serves as a system code or a
password between the transmitter and the target receiver.

Select the desired system code
by shifting the keys with a ball­point pen or a small screw­driver. All wireless units used in
the system and the target
receiver must be programmed
with the same digital code.

Figure 3. Code Selector

Caution: The factory test code combination 2, 4, 5, 6, 7 ON /

1, 3, 8 OFF must not be used. Also avoid codes which are often
used: all keys ON, all keys OFF or alternating ON/OFF settings.

3.3 Channel Selection

!

Each transmitter can be set to transmit one of four different
"channel codes". The channel code is added to the system code
to activate a specific output in a multi-output receiver. Channel
codes are very useful for zoning purposes (activating various
types of zones of an alarm control panel).

The channel code selector consists of a 4-position DIP switch,
with keys marked from 1 to 4. The code is selected by switching
the corresponding key(s) to ON. You may select more than one
channel code for simultaneous activation of several channel
outputs at the receiver.

Note: Channel 2 code is transmitted automatically as a tamper
alert whenever the front cover is removed.

Setting all four-channel keys to
OFF will activate the buzzer at
the receiver (same as low
battery alert) and none of the
receiver's channel outputs.

Figure 4. Selecting Channel 2

3.4 Input Sensitivity Adjustment

Input sensitivity for vibration detectors is adjusted with the SENS.
potentiometer. The sensitivity is at maximum (response time
about 5 ms) with the control knob rotated fully towards [+] and at
minimum (response time about 30 ms) with the control knob
rotated fully towards [–]. If you are not using a vibration detector,
set the control fully towards [–].

3.5 Wiring

!

Normally closed sensors and inertial vibration detectors are wired
in series between the terminals marked N.C.

Note: If the N.C. input is not used, it must be shorted by installing
a jumper on the N.C. header below the terminal block (Fig. 1).

Normally open alarm contacts should be wired in parallel with the
terminals marked N.O..

Visonic Ltd. low current
SRN-2000C/PC series PIR
detectors may be powered
from the 1st (+) and 2nd (–)
terminals from the left.
When using the same
battery for the transmitter
and the PIR detector,
low-battery supervision is
obtained for both units.

Figure 5. Terminal Block Wiring

To use the reed switch, remove the reed switch jumper "J1"
(located near the reed switch).

3.6 Battery Installation

Note: Before installing the battery, use some masking tape to
temporarily keep the tamper switch lever down. This will prevent
the unit from continuously transmitting a tamper alert while the
front cover is removed for testing.

The units are powered by a 9-volt alkaline or lithium battery.
For proper operation, use only an alkaline or lithium battery.

Snap the battery clip onto the battery terminals and put the
battery in place (above the PC board).

3.7 Testing

!

A. Select the desired system code as instructed in Section 3.2.
B. Select a channel code as instructed in Section 3.3.
C. Activate the sensor connected to the transmitter input.

Note: If a vibration detector is used, adjust the sensitivity with
the SENSE control (see Section 3.4).

D. Verify that the transmitter LED lights during transmission.
E. WT-100: Leave the sensor input disturbed for several

minutes. Verify that the unit repeats the transmission for
approximately 2 seconds each minute.

WT-100A: As with WT-100, but verify transmission only once.

F. Check whether the receiver’s LED lights steadily, indicating

good detection of the RF signal.

G. Verify that the receiver's corresponding relay energizes while

receiving a signal.

H. Restore the transmitter's input to its undisturbed state, set all

4 channel switches to OFF and initiate a transmission. This
should cause the low-battery alert buzzer at the receiver to
sound (provided that a buzzer is connected to the receiver).

I. Re-select the desired channel code with the four channel

switches.

J. Remove the masking tape used to hold down the tamper

switch lever. The transmission triggered by the tamper switch
should cause channel 2 relay of the receiver to energize.

K. Carefully position the front cover hole over the LED. Secure

the front cover to the base with the screw and insert the
plastic cap into the hole (Fig. 2).

4.1 Product Limitations

Visonic Ltd. wireless systems are very reliable and are tested to
high standards. However, due to low transmitting power and
limited range (required by FCC and other regulatory authorities),
there are some limitations to be considered:

A. A receiver may be blocked by radio signals sent on or near its

operating frequency, regardless of the digital code used.

B. A receiver responds to one transmitted signal at a time.
C. Wireless equipment should be tested regularly to determine

whether there are sources of interference and to protect
against faults.
