4550-CB
INSTALLATION
A. General Considerations
Determine where to mount the unit. Keep the following in mind:
a. Obtain the best transmitted and received signal strength for the cellular
radio. (If a very strong cellular signal is not available, first power the unit
with the AC power and turn on S4 to test for the location that provides the
best signal strength.)
b. Proximity to a Plug for the AC transformer.
c. Proximity to the alarm panel and where to route the 4550-CB unit’s relay
outputs that connect to the alarm panel unit’s inputs, and vice versa.
(These wires will need to be in conduit for a UL certificated installation.
See the UL Compliance Section.)
d. Proximity to the RJ31X Telco jack from the telephone system.
B. DIP Switch Settings
The 4550-CB has a four-position dipswitch. The dipswitches function as follows:
SWITCH NO.

RSSI Measurements
Battery Mode is a low current default that extends battery life to its maximum
in accordance with UL requirements. In this mode, the amp-hour rating of the
battery is approximately equivalent to the number of days that the unit will operate
in standby before the battery is depleted, assuming that an active phone line has
been plugged into the unit.
