Safety Informaion
IMPORTANT
The equipment is fixed, wall-mounted and shall be installed in the position specified in these instructions (see
Figure 1: Parts). The equipment enclosure must be fully assembled and closed, with all the necessary
screws/tabs and secured to a wall before operation. Internal wiring must be routed in a manner that prevents:
- Excessive strain on wire and on terminal connections
- Loosening of terminal; connections
- Damage of conductor insulation
Never install this equipment during a lightning storm!
Instruct the end-user to:
- Not attempt to service this product. Opening or removing covers may expose the user to dangerous voltages
or other risks. Any servicing shall be referred to trained service persons only.
- Use authorized accessories only with this equipment.
Do not dispose of the battery in fire or water. Disposing of the battery in a fire will cause rupture and explo-
sion.
Do not dispose of the waste battery as unsorted municipal waste. Consult your local regulations and /or laws
regarding recycling with regard to this lead-acid battery. Doing so will help protect the environment. Some of
the materials that are found within the battery could become toxic if not disposed of properly and may affect
the environment.
This equipment, LE4020/LE4020CF, is fixed and shall be installed by Service Persons only (Service Person is
defined as a person having the appropriate technical training and experience necessary to be aware of hazards
to which that person may be exposed in performing a task, and of measures available to minimize the risks to
that person or other persons). It shall be installed and used within an environment that provides the pollution
degree max 2, over voltages category II, in non-hazardous, indoor locations only. This manual shall be used
with the Installation Manual of the relevant alarm control panel. All instructions specified within that manual
must be observed.
The performance of the LE4020/LE4020CF depends greatly on cellular network coverage. Therefore, it should
not be mounted without first performing placement tests to determine the best location for reception (minimum
of one green LED ON). Optional antenna kits – LTE-15ANT, LTE-25ANT, LTE-50ANT (15ft/4.6m, 25ft/7.6m
or 50ft/15.2m) – are available.

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.
