Each version of Alarm Communicators covered by this Installation Manual are described
below:
LE2077: A Long-Term Evolution/Global System for Mobile (LTE/3G) wireless Alarm
Communicator that sends alarm communication to Sur-Gard System I-IP, II, III (SG-DRL3-
IP), IV (SG-DRL4-IP) and 5 (SG-DRL5-IP) central station receivers through an LTE/3G
digital cellular network.
CAUTION:
