Figure 3. Wiring Example with E.O.L resistors
Notes:
1. An alarm message will be translated once the loop is opened
or short circuited.
2. Use jumper wire to ground any unused input (DIP switch SW1
or SW2 must be set to off).

Before testing, set DIP switches SW1 through SW4 as required
for the particular application.
The MCT-100 is equipped with
a 4-position DIP switch function
selector (Fig. 4). Each switch
lever allows you to select one
of two options, as explained in
the following table:
Figure 4. Function Selector

Input 1 is E.O.L. (47 k

Input 2 is E.O.L. (47 k

Alarms reported only once
SWITCH SW1: Determines whether input 1 (IN1) will behave as
a 47 k
Ω
End-of line (E.O.L.) input or as a normally closed (N.C.)
input.
SWITCH SW2: Determines whether input 2 (IN2) will behave as
a 47 k
Ω
End-of line (E.O.L.) input or as a normally closed (N.C.)
input.
SWITCH SW3: Determines whether the transmitter will report a
restore event when an input restores from an alarm condition.
Note: If the MCT-100 is used in conjunction with motion
detectors, there is no point in setting SW3 to ON, because the
detector restores automatically after an alarm. However, when
the MCT-100 is used with a door or window magnetic switch,
selecting the ON position will enable you to find out whether the
door or window under surveillance are open or closed.
SWITCH SW4: In non-supervised systems, it is sometimes
required to report an alarm repeatedly at short intervals, until the
disturbed input reverts to its normal (undisturbed) state. Switch
SW-4 is used to select between repetitive and one-shot
transmission.
Note: Transmissions initiated by "tamper” events will be repeated
once every 3 minutes, regardless of SW4 setting.

A . Insert the 1/2 AA battery between the battery clips, making
sure that the polarity is correct. For proper operation, only
Lithium Thionyl Chloride battery (as specified in Section
2) should be used.
Note: Before each supervision report, the battery voltage is
tested. If a low battery condition is detected, a "low battery"
alert signal will be included in the supervision message.
If the battery is not replaced, all following transmissions will
include the "low battery" alert signal, which has to be acted
upon without delay.
B. Since the cover is removed and power is applied, a tamper
situation exists. Verify that the MCT-100 transmits (the LED
lights briefly) once every 3 minutes.
C. When you are satisfied that tamper transmissions are carried
out properly, put the cover back on to return the tamper switch
to its normal undisturbed position. Wait slightly over 3 minutes
to verify that tamper transmissions cease.
D. Momentarily disturb any one of the sensors connected to the
first input (IN1) and verify that the transmitter LED lights,
indicating that transmission is in progress. IF SW-4 is on, wait
3 minutes to verify that the transmission is repeated at
3-minute intervals.
E. Restore the sensor to the undisturbed state and watch the
LED. If SW-3 is set to ON, another transmission will take
place upon restoral.
F. Repeat Steps C and D above with the second input (IN2).
G. Refer to the target receiver's installation instructions, and let
the receiver "learn" the ID codes associated with both inputs
of the MCT-100.
REMEMBER! Because each input of the MCT-100 acts as
an independent transmitter with an individual ID, make sure
that both input IDs are learned by the receiver.
H. Secure the front cover with the screw and screw cap (Fig. 2).

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 regulating authorities),
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 digital code
used.
B. A receiver can only respond to one transmitted signal at a
time.
C. Wireless equipment should be tested regularly to deter-mine
whether there are sources of interference and to protect
against faults.
