MCT-100 (3.6V)

Supervised Two-Input PowerCode Wireless
Transmitter
Installation Instructions
1. INTRODUCTION
The MCT-100 is a fully supervised, two-input PowerCode wireless
transmitter designed 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. An on-board programming DIP switch
allows the installer to disable input No. 1 (IN1) in applications
where only a single input is needed.
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.
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 sent by other PowerCode transmitters, a "smart"
anti-collision transmission sequence is used (see Appendix A).
The MCT-100 is protected by a tamper switch, activated when
the cover is removed. Once the tamper switch contacts open, a
message will be transmitted from input 1 with the “tamper alert”
marker ON. If the installer disables input 1, the tamper situation
will be automatically reported by input 2 instead.
A periodic supervision message, distinguished by a specific
marker, is transmitted automatically from input 1 only (if enabled)
or from input 2 only (if input 1 is disabled) once in 60 minutes.
The receiver is thus informed, at regular intervals, of the
MCT-100 active participation in the system.
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 (Appendix A).
