ENGLISH
1. INTRODUCTION
The MCT-302 is a fully supervised, PowerCode magnetic contact
transmitter. For UL installations, the MCT-302 is for use with the UL listed
control unit, model P only. The transmitter includes a built-in reed
switch (that opens upon removal of a magnet placed near it) and an auxiliary
hard-wired input, programmable as either N.C. or E.O.L., for use with
additional sensors - pushbuttons, detectors, door contacts etc.
An on-board DIP switch allows the installer to disable the magnet-
operated reed switch if only the auxiliary input is needed.
The reed switch and the auxiliary input behave as separate transmitters,
although they trigger the same RF transmitter. Each input has a unique
24-bit PowerCode ID, selected in the factory from over 16 million possible
code combinations.
Since messages transmitted by the MCT-302 might collide with
transmissions from other PowerCode transmitters, a "smart" anti- collision
transmission sequence is used.
The MCT-302 tamper switch is activated when the cover is removed.
A periodic supervision message, is transmitted automatically. The target
receiver is thus informed, at regular intervals, of the unit’s active participation
in the system.
An LED lights whenever alarm or tamper events are reported. The LED
does not light while a supervision message is being transmitted.
Operating power is obtained from an on-board 3 V Lithium battery. When
the battery voltage is
low, a “low battery” message is sent to the
receiver.

This device complies with Part 15 of the FCC Rules and RSS-210 of
Industry and Science Canada. Operation is subject to the following two
conditions: (1) This device may not cause harmful interference, and (2)
this device must accept any interference received, including interference
that may cause undesired operation.
This device complies with the essential requirements and provisions of
Directive 1999/5/EC of the European Parliament and of the Council of 9
March 1999 on radio and telecommunications terminal equipment.
3. INSTALLATION
3.1 Mounting
(Fig. 2)
It is highly recommended to attach the transmitter to the top of the
door/window on the fixed frame and the magnet to the movable part (door or
window). Make sure that the magnet is located not more than 6 mm (0.25
in.) from the transmitter’s marked side.
Note:
Once the cover is removed, a tamper message is transmitted to the
receiver. Subsequent removal of the battery prevents transmission of
"TAMPER RESTORE", leaving the receiver in permanent alert. To avoid
this, during the enrolling process, press the tamper switch while you
remove the battery.
3.2 Auxiliary Input Wiring
(Fig. 3)
Remember!
If your application does not require the auxiliary input,
be
sure to set DIP switch
SW2
to
OFF
and to short the input terminals
together with a piece of jumper wire.
A
. Connect the auxiliary sensor contacts across the MCT-302 auxiliary
input terminals.
B.
If the auxiliary input of the MCT-302 is defined as a Normally Closed
(N.C.) type (
SW2
set to
OFF
), series connected N.C. sensor contacts
must be used exclusively. An E.O.L. resistor will not be required.
C.
For E.O.L. supervision, set
SW2
to
ON.
Normally Closed (N.C.) as well as Normally Open (N.O.) sensor
contacts can be used, as show in figure 3. A 47k
Ω
E.O.L. resistor
must be wired at the far end of the zone loop.
Note:
For UL installations, the device connected to the initiating circuit
must be located in the same room as the transmitter.
4. PREPARATION FOR USE
4.1 The Function Switches
A. Switch Tasks
The MCT-302 has a 4-position DIP switch function selector. Each
switch lever allows you to select one of two options
.
B. Setting the Switches
Set the function switches as desired prior to
applying power. Use a ball point pen or another
pointed object to shift the switch levers.
The ON
position is indicated by the arrow on the switch
body.

SWITCH SW1:
Determines whether the reed switch input will be active or
inactive.
SWITCH SW2:
Determines whether the auxiliary input will behave as an
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:
Selecting the ON position enables you to find out whether the door
or window under surveillance are open or closed.
Note: For UL installations, SW3 must be set to On position.
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.
SW4
is used to select between
repetitive and one-shot transmission. For CE compliance, SW4 must be
set to OFF.
Note:
Transmissions initiated by “tamper” events will be repeated once
every 3 minutes, regardless of
SW4
setting.
When done, Install the battery as directed in Para. 4.2.
4.2 Testing the Unit
Before testing, set DIP switches
SW1
through
SW4
as required for the
particular application (Para. 4.1).
A.
Insert the battery between the battery clips, at the correct polarity. For
proper operation, only Lithium Thionyl Chloride battery (Panasonic,
Sanyo, or GP type CR2) should be used.
Caution:
Risk of explosion if battery is replaced by an incorrect type.
Dispose used battery according to manufacturer's instructions.
B.
Press the tamper switch once and release it.
Note:
Since the cover is removed and power is applied, a tamper
situation exists. Verify that the MCT-302 transmits (the LED lights
briefly) once every 3 minutes.
C.
When you are satisfied that tamper signals are transmitted properly,
put the cover on to return the tamper switch to its normal
(undisturbed) position. Wait slightly over 3 minutes to verify that
tamper transmissions cease. If all went well, secure the front cover to
the base with the case closure screw.
