Section 1: Introduction
The Model 4724 Control Expander is a UL Listed, plug-on unit that provides greatly enhanced
software features, event storage memory, and user-friendly operation for the Model 4720 Con-
trol/Communicator. The 4724 replaces the control microprocessor on the 4720 (or on the obso-
lete Model 4721 Area Control Software). It allows full use of up to two zone expanders for a
system maximum of 144 zones.
The 4724 supports the Model 4181 (PL513) Power Line Control Interface, which controls X-
10 Modules at various locations. These X-10 Modules make it possible to automatically turn
lamps and other appliances on and off at preprogrammed times or as the result of system sta-
tus.
The Model 4724 hardware is powered by the 4720 hardware and supports the same expansion
devices as the 4720. The 4724 can be added to existing 4720 (or 4721) installations.
