MCT-237
Wireless CodeSecure™ Two-Way Keyfob Transmitter
1. INTRODUCTION
1.1 Description
The MCT-237 is a miniature CodeSecure™ 6-button keyfob
transmitter, designed for use with the PowerMax Pro unit. The
device enables the user to arm/disarm the alarm system and to
view system status.
For each PowerMax Pro control panel, a maximum of eight
MCT-237 keyfob devices may be enrolled. Operating power is
obtained from an internal 1.5 V alkaline battery. Each transmitter
is supplied with a small keyring.
Transmission is initiated by pressing any one of the six
pushbuttons. Upon pressing a specific button, the keyfob
transmits a CodeSecure™ digital sequence identifiable by the
PowerMax unit, and a 4-bit function code associated with the
button that was pressed.
The next time a button is pressed, the keyfob will transmit a digital
sequence of three transmissions that differs from the one used in
the previous transmission and the respective function code. As a
result, malicious "code grabbing" is virtually impossible.
The main features of the MCT-237 are:
• Status, alarm memory, and trouble data retrieval from PowerMax Pro.
• Visual indications by LCD icon display.
• LCD backlighting activation.
• Various audible signals sounded by the speaker in response to
specific actions.
• 1.5 Volt Alkaline battery.

3. TESTING AND MAINTENANCE
3.1 Testing a New Unit
Since the keyfob transmitter is supplied with the battery already
installed, the unit is practically ready to be tested.
IMPORTANT! Before testing, "teach" the PowerMax Pro the
ID code of the keyfob, as instructed in the PowerMax Pro
Installer Guide.
A. Stand near the PowerMax Pro control panel and press the
keyfob button marked with a closed padlock icon.

B. Make sure that the control panel responds as programmed and
as stated in the PowerMax Pro Installer Guide.
C. Operate the keyfob from various locations within the area
covered by the receiver to determine "dead" locations, where
transmission is blocked by walls and large objects, or affected by
structural materials. For optimum operation, point the keyfob
directly toward the PowerMax Pro control panel.
Note: If dead/marginal zones are a problem, relocating the
PowerMax Pro control panel may improve the performance.
