This manual covers two communicator models, the LE4020 and the LE4020(CF). They are referred to

throughout 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 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 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 install-

ation 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.

Technical Specifications

The input voltage to the LE4020/LE4020CF can be drawn from the UL/ULC Listed control panel or

provided by an external UL/ULC Listed power supply rated for the application (external power-limited

source).

NOTE: The power supply must be Class 2, Power Limited. For residential applications a suitable power

adaptor is model DSC ADP1310(W)-NAU or DSC ADP1320-NAU (for USA) and model DSC ADP1310(W)-

NA (for Canada).
