Section 1: Introduction
This manual covers two communicator models, the LE4020 and the LE4020CF. They are referred to through-
out this manual as LE4020/LE4020CF unless otherwise indicated.
This LE4020/LE4020CF manages transmissions to a central station and can simulate the landline in the event
of trouble (e.g., landline down) or even substitute the landline completely in areas where the 3G/LTE or 2G
cellular service is provided and a landline is not available.
By connecting a to a control panel's standard PSTN interface, telephone-based Contact ID or SIA signals are
decoded and seamlessly routed through the LTE or 3G network to any of the compatible receiver options.
The LE4020/LE4020CF are wireless communicators for UL/ULC commercial fire and/or burglary applications.
Both models send alarm system information to a Sur-Gard System I-IP, II, III, IV or 5 receiver. The
LE4020/LE4020CF uses the LTE or 3G wireless network. The LE4020/LE4020CF can be used with UL/ULC
Listed compatible control units, as indicated in the manufacturer's installation instructions.
Note:
These communicators are designed to work with the Contact ID communication format as described in
the SIA DC-05 standard and the SIA DC-03 standard for 300 baud. Before completing the field installation of
the alarm monitoring system please ensure communication with the supervising central station is successful by
sending several events and getting confirmation that they have been received.
