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

Module Identification
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.
