Supervised PowerCode Magnetic Contact Transmitter

1111. INTRODUCTION

. INTRODUCTION

. INTRODUCTION. INTRODUCTION

The MCT-302 is a fully supervised, PowerCode magnetic contact
transmitter. It features 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 trans-

mitters, although they trigger the same RF module into transmission.
Each input has a unique 24-bit PowerCode ID, selected in the factory
from over 16 million possible code combinations.

Upon alarm, a digital message is transmitted, composed of the
disturbed input’s PowerCode ID followed by various status and
message-type markers. Alarm and other data are thus forwarded to
the receiver.

Since messages transmitted by the MCT-302 might collide with
transmissions from other PowerCode transmitters, a "smart" anti­collision transmission sequence is used.

The MCT-302 tamper switch is activated when the cover is removed.
In a tamper situation, a message is transmitted from the reed switch
input with the “tamper alert” marker ON. If the installer disables the
reed switch, tamper is reported by the auxiliary input instead.

Frequency (MHz): 315, 433.92, 868.95 or other per local
requirements (UL has only investigated at 315 MHz).
Transmitter's ID Code: 24-bit digital word, over 16 million
combinations, pulse width modulation.

Overall Message Length: 36 bits
Alarm Inputs: 2, one internal and one external, with a separate 24-bit

transmitter ID each.

Auxiliary Input Circuit Type: N.C. / E.O.L., selected with DIP switch
E.O.L. Resistor Required: 47 kΩ

Message Repetition: Repetitive transmission (once every 3 minutes)

or one-shot, as selected with on-board DIP switch.
Supervision: Signaling at 60-minute intervals or according to the local
standard from the reed switch (if enabled) or from the aux. input (if the
reed switch is disabled).
Response to Tamper Event: Tamper report every 3 minutes (until
the tamper switch is restored).
Power Source: 3 V Lithium CR-2 type battery, Panasonic or
equivalent.

A periodic supervision message, distinguished by a specific marker, is
transmitted automatically from the reed switch input only (if enabled) or
from the auxiliary input only (if the reed switch is disabled) once every
15 minutes (Europe) or once every 60 minutes (USA), or according to
local standards. 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 Thionyl
Chloride battery. A weak battery will cause a “low battery” marker to
be added to any message transmitted.

NOTE: ONCE THE COVER IS
TAKEN OFF AN ACTIVE MCT­302 UNIT, A TAMPER MES­SAGE IS TRANSMITT ED TO
THE RECEIVER.

3.1 Mounting

It is highly recommended to attach the transmitter to the fixed
frame and the magnet to the movable part (door or window), as
shown in Figure 2. Make sure that the magnet is located not more
than 6 mm (0.25 in.) from the transmitter’s marked side.

A. Remove the case closure screw (Figure 3).
B. Remove the unit’s cover as shown in Figure 4.
C. Flex out the circuit board retainer (Figures 1 and 5) and

detach the circuit board from the base.

D. Hold the base against the mounting surface and mark the drilling

points through the mounting holes (Figure 5).

E. Drill the holes and fix the base to the wall using the 2 screws with

countersunk heads supplied in the package

CAUTION! Screws with other type or size of head may short
circuit the bottom side of the printed circuit board.

F. Mount the magnet near the marked side of the MCT-302.
G. Insert the edge of the P.C. board with the RF module into the

edge supports, and press the other edge against the flexible
retainer until it snaps home with a click.

4.1 The Function Switches

A. Switch Tasks

The MCT-302 has a 4-position DIP switch function selector (Figure 7).
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.

Note:

periodic supervision transmissions.

SWITCH SW2: Determines whether the auxiliary input will behave as
a 47kΩ 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:

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. SW4 is used to select
between repetitive and one-shot transmission.

once every 3 minutes, regardless of

A. Connect the auxiliary detector’s alarm 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. If the auxiliary input is defined as an E.O.L. type (SW2 set to ON),

Normally Closed (N.C.) as well as Normally Open (N.O.) sensor
contacts can be used. A 47kΩ E.O.L. resistor must be wired at the
far end of the zone loop, as in Figure 6.

Note: An alarm message will be transmitted

once the loop is opened or short circuited

4.2 Testing the Unit

Before testing, set DIP switches SW1 through SW4 as required for
the particular application (Para. 4.1).

Insert the battery between the battery clips, at the correct polarity.

A .

For proper operation, only Lithium Thionyl Chloride battery
(Panasonic type CR2 or equivalent) should be used.

Press the tamper switch once and release it.

B .

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.

When you are satisfied that tamper alerts are transmitted

C .

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.

Momentarily open the door or window and verify that the

D .

transmitter LED lights, indicating that transmission is in progress.
If SW4 is ON, wait 3 minutes to verify that the transmission is
repeated at 3-minute intervals.

Close the door or window, thus restoring it to the undisturbed

E .

state and watch the LED. If SW3 is set to ON, a “restore”
transmission will now take place.

If the auxiliary input is used, momentarily activate the detector

F .

connected to it and check for a response similar to that described
in D above. Then restore the input loop to its undisturbed state.
The response should be as in E above.

Refer to the target receiver’s installation instructions, and let the

G .

receiver “learn” the ID codes associated with the reed switch (if
used) and the auxiliary input (if used).

ATTENTION!

must enroll the ID that you are using (if you are using the
internal reed switch, activate the reed switch. If you are using
the AUX input, trigger this input. If you are using both, activate
the reed switch and then trigger the AUX input, or vice versa).

With the target receiver in the LEARN mode, an alarm
transmission from each input will enroll the input’s ID in the
receiver’s memory.

Note Regarding Tamper Message Transmission

- If the reed switch input is enabled (
message will be sent with the reed switch’s ID.

- If the reed switch input is disabled (
message will be sent with the auxiliary input’s ID.

Each input of the MCT-302 has a different ID. You
