CDMA Primary Cellular
Alarm Communicator
®
CDMAEX
INSTALLATION
A. General Considerations
Determine where to mount the unit. Keep the following in mind:
a. Where to obtain the best transmitted and received signal strength for the
cellular radio. (If the installer does not have a very strong cellular signal
in his area, he may want to first power the unit from a portable 12V DC
source, switch on S4 and move the unit to a location that gives him the
best signal strength.)
b. Proximity to the alarm panel and where to route the CDMAEX’s relay
output that connects to an alarm panel input.
B. DIP Switch Settings
The CDMAEX has a four-position dipswitch. The dipswitches function as follows:
SWITCH NO.
