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.

3.1 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. 
3.2 Replacing the Battery 
Caution: Risk of explosion if battery is replaced by an incorrect 
type. Dispose of used batteries according to the instructions.
 
The battery should be replaced upon receiving a low battery LCD 
indication. A replacement 1.5 V AAA alkaline battery, such as GP 
(or equivalent), should be used. Replace the battery as follows:
