1. INTRODUCTION
. 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 sens or
to the point on the glass farthest from the sensor (s ee 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 i s
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, select ed 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 transmis sions
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 i s 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 s pecific
marker, is transmitted automatically once in 60 minutes . The
wireless control panel is thus informed, at regular int ervals, 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 report ed.
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.
