Transmitter
,1752'8&7,21
The MCT-100 is a fully supervised PowerCode, two-input
wireless transmitter for electronic security applications. Both
inputs can be set to operate with a normally closed (N.C.) loop, or
with an end-of-line (E.O.L.) loop in which both N.C. and N.O.
sensors can be used.
Each input has an individual 24-bit PowerCode ID which
identifies it to the target receiver as if it were a separate
transmitter.
Each ID is randomly selected in the factory from 16 million
possible code combinations and retained in the non-volatile
memory of the MCT-100.
Compatible receivers can "learn" specific IDs and respond only to
them.
Disturbing an input loop of the MCT-100 initiates transmission of
the specific input's PowerCode ID followed by various status and
mode designators. Alarm information and other data are thus
forwarded to the alarm control panel or to the head-end
computer, depending on the type of system in which the
MCT-100 is used. Since messages transmitted by the MCT-100
might collide with messages transmitted by other PowerCode
transmitters, a "smart" anti-collision transmission sequence is
used (Para. 3.2). Each input initiates its own transmission of a
periodic "supervision" message once every 60 minutes. The
receiver is thus informed, at regular intervals, of the input's active
participation in the system.
63(&,),&$7,216
Frequency (MHz): 315, 404, 418, 433.92 or other frequencies

Installation Instructions

An indicator LED lights during transmission 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"
designator to be added to any message transmitted (Para. 3.4).
Nominal Battery Capacity: 1.2 Ah
Current Consumption: 5 µA standby, 8 mA in operation
(including LED)
Battery Life (with LED on):
@ 10 transmissions per day: Over 10 years
@ 50 transmissions per day: About 6 years
Battery Supervision: Automatic transmission of a battery
condition data as part of any status report.
Operating Temperature: 0°C to 49°C (32°F to 120°F).
Dimensions: 110 x 63 x 25 mm (4-5/16 x 2-1/2 x 1 in.).
Weight: 66.5 g (2.34 oz)
Compliance with Standards: Meets FCC Part 15, ETS 300-220
and MPT1349
The 418 & 433.92 MHz models of this device comply with the
European Council Directive EMC 89/336/EEC & 92/31/EEC, and
bear the CE mark and certification.

Route the wires through a wiring knockout in the base.
If an input is defined as a Normally Closed (N.C.) type (SW-1 or
SW-2 are set to OFF), series connected normally closed sensor
contacts must be used exclusively.
If an input is defined as an E.O.L. type, Normally Closed (N.C.)
as well as Normally Open (N.O.) sensor contacts can be used. A
47 kΩ resistor must be wired at the far end of the E.O.L. zone
loop, as in Figure 3.
