Advanced Acoustic Sensor / PowerCode Transmitter

. INTRODUCTION

. INTRODUCTION. INTRODUCTION

The MCT-501 combines two modules:

•••• The Sentrol Inc. ShatterPro™ acoustic sensor with Pattern

Recognition Technology™ (Protected under U.S. Patent
5,192,931)

•••• The Visonic Ltd. MCT-302 PowerCode™ transmitter

1.1 Acoustic Sensor

The acoustic sensor module of the MCT-501 is omni-directional,
providing 360° coverage. Coverage is measured from the sensor
to the point on the glass farthest from the sensor (see Fig. 3). The
sensor can be mounted as close as 1 m (3.3 ft) from the glass.

Figure 3. Typical Range Measurement

When mounted on opposite wall or adjoining walls, the range is
6 m (20 ft) for plate, tempered, laminated and wired glass.

When mounted on the ceiling, the maximum range is 6 m (20 ft)
for plate, tempered, laminated and wired glass

For armor-coated glass, mount the sensor no more than 3.65 m
(12 ft) from the glass.

1.2 PowerCode Transmitter

The acoustic sensor shares its housing with a miniature
transmitter which has a unique 24-bit PowerCode ID, selected in
the factory from over 16 million possible code combinations.

Upon alarm (glass break detection), a digital message is
transmitted, composed of the PowerCode ID followed by various
status and message-type markers. Alarm and other data are thus
forwarded to the wireless alarm control panel.

Since transmitted messages might collide with transmissions
from other PowerCode transmitters used in the system, a smart
anti-collision transmission sequence is used.

The MCT-501 is protected by a tamper switch that is activated
when the cover is removed. In a tamper situation, a message is
transmitted with the “tamper alert” marker ON.

A periodic supervision message, distinguished by a specific
marker, is transmitted automatically once in 60 minutes. The
wireless control panel is thus informed, at regular intervals, of the
sensor’s active participation in the system.

A red LED mounted on the transmitter PCB (visible only when the
cover is off) 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 3.6 V Lithium
Thionyl Chloride battery. A weak battery will cause a “low battery”
marker to be added to any message transmitted.

. INSTALLATION. INSTALLATION

3.1 Optimizing Detection and Avoiding
False Alarms

For best detection, avoid installing in:

!

Rooms with lined, insulating, or sound deadening drapes.

!

Rooms with closed wooden window shutters inside.

For best false alarm immunity:

!

Avoid 24-hour loop applications (perimeter loop OK).

!

Don't use where white noise, such as air compressor noise, is
present (a blast of compressed air may cause a false alarm).

!

Avoid rooms smaller than 3 x 3 m (10 x 10 ft) and rooms with
multiple noise sources such as small kitchens, glass booths
noisy areas, garages, small bathrooms, etc.

Areas to avoid:

!

Glass airlocks and glass vestibule areas

!

Noisy kitchens

!

Residential car garages

!

Small utility rooms

!

Stairwells

!

Small bathrooms

!

Other small acoustically live rooms. For glass break protection
in such applications, use shock sensors on the windows or
window frames.

Do Not Install In Humid Rooms The Wireless MCT-501 is not
hermetically sealed. Excess moisture on the circuit board can
eventually cause a short and a false alarm.

Avoid 24-Hour Loop Applications The MCT-501 is
recommended for perimeter loops and is designed to function in
occupied area. In 24-hour loop applications, where the sensor is
armed all day and all night, the false alarm prevention technology
will be pushed to its limit. Some sounds can duplicate the glass
break pattern the acoustic sensor detects.

Install the MCT-501 on a perimeter loop which is armed
whenever the door and window contacts are armed.

Protecting Occupied Areas

The false alarm immunity is best in rooms with only moderate
noise. For 24-hour occupied area protection, use shock sensors.

Proper Testing

The MCT-501 is designed to detect the breaking of framed glass
mounted in an outside wall. Testing the sensor with unframed
glass, broken bottles, etc., may not trip the sensor. The sensor
typically does not trip to glass breaking in the middle of the room.
No burglar breaks glass in the middle of a room, so such “breaks”
are false alarms.

NOTE: MCT-501 may not consistently detect cracks in glass, or
bullets which break through the glass. Glass-break sensors
should always be backed up by interior protection.

For best false alarm immunity the sensor should be located at
least 1.2 m (4 ft) away from noise sources (televisions, speakers,
sinks, doors, etc.). The sensor must always be in direct line of
sight of all protected windows. It cannot consistently detect glass
breaking around corners, in other rooms, etc. Front or back, up or
down orientation is not necessary.

3.3 Preparing the Unit

A. Use a screwdriver to

separate the cover
from the base, as
shown in Figure 4.

You will find inside a
nylon bag with the
battery, two masonry
anchors (wall plugs)
and two mounting
screws.

B. Get to know the

items indicated in
Fig. 5 - they are all
relevant to the steps
you will have to take
in the course of
installation.

C. Verify that all 4 DIP

switch levers are set
to OFF as shown in
Figure 6 below. If not

- set them all OFF.

Figure 6. DIP Switches - Correct Position

D. Insert the battery into the battery clips, as shown in Figures 7

and 8. Observe Polarity!

3.2 Sound Travel Considerations

Since the sound of breaking glass travels directionally out from
the broken window, the best location for mounting the sensor is
on the opposite wall - assuming the glass to be protected is within
the sensor's range and line of sight. The ceiling and adjoining
(side) walls are also good sensor locations. A ceiling mounted
sensor will have better detection if positioned 2 - 3 m (6 - 10 ft)
away from the protected glass into the room.

As with all glass-break sensors, detection is reduced with
same-wall mounting, since such detection is partially dependent
on glass break sound reflecting off the opposite wall. Test the
range with Sentrol 5709C unit held flat against the glass. There
may be a reduction in range, depending on room acoustics.

Figure 7. Battery Insertion

E. Click the tamper switch

once and release it to reset
the transmitter at power up.

Note: Since the cover is
removed and power is
applied, a tamper situation
exists. Verify that the
MCT-501 transmits (the
transmit LED lights briefly)
once every 3 minutes.
