1. 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" anti-

collision 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.

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.

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

.

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.
