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.

Section 2: Installing the LE4020/LE4020CF
2.1 C24 Communications Enrollment
The LE4020/LE4020CF requires enrollment with C24 Communications to operate. For more information,
please visit www.connect24.com, contact C24 Communications customer service at 1-888-251-7458 (US) / 1-
888-955-5583 (Canada) or contact the central station to inquire if they are a C24 Communications Master
Reseller.
Note: Enrollment with C24 Communications should be performed before turning on the LE4020/LE4020CF
unit.
Before inserting or removing the SIM card, please ensure the unit is turned off.
Step 1 - Initialize the LE4020/LE4020CF with C24 Communications
The LE4020/LE4020CF can be initialized with C24 Communications by:
web - www.connect24.com
mobile - m.connect24.com
To complete enrollment, a C24 profile, installer ID/PIN (or web credentials) and the 20-digit SIM number are
required.
Note: The SIM activation process with the cellular carrier typically takes between five and ten minutes to com-
plete.
Step 1 - Determine the Best Signal Location
1. Detach the front cover by removing the four screws.
2. Apply power (DC and/or battery). The LE4020/LE4020CF is now in Placement Test mode.
Step 2 - Determine Best Signal Location
1. Remove the screws and the front cover of the LE4020/LE4020CF metal enclosure [1].
2. Fit the antenna [2] (ensure that the bolt [3] is fastened tightly).
3. Connect the antenna to the 3G Radio [5] and ensure the connector is secure.
Note: Before inserting or removing the SIM card, please ensure the unit is powered down.
4. Ensure the SIM card is placed in its socket [6].
5. Power up the LE4020/LE4020CF module [4]Use a DC power source rated 12V/0.7A connected to +/-
12V terminals [9]
Step 2a – SIM Card Is Activated.
The red LED is on solid, the blue LED is off and the signal strength LEDs display the average signal strength.
In this state, the LE4020/LE4020CF is registered to the network.
Red Blue Blue/Green

ON OFF - -
If the signal strength is too low (bottom signal LED off or flashing), the LE4020/LE4020CF will proceed to
Step 3: scan for, and attach to, carriers with sufficient signal strength. If the LE4020/LE4020CF is connected to
a carrier with sufficient signal strength (minimum of bottom signal strength LED on solid), it proceeds to Step
4.
Step 2b – SIM Card Is Not Activated
The red LED flashes, the blue LED is off and the signal strength LEDs display the average signal strength.

Red Blue Blue/Green

FLASHING OFF - -
In this state, the LE4020/LE4020CF is unable to register to the network because it is inactive. The signal
strength indicated is from any nearby cell tower (including cellular towers belonging to non-roaming partners)
and does not necessarily reflect the signal strength of the intended network. The LE4020/LE4020CF remains
in this state until the SIM is activated. Once the SIM is activated, the LE4020/LE4020CF proceeds to Step 2a.
Step 3 – Carrier Scanning Due To Insufficient Signal Strength
The LE4020/LE4020CF scans the surrounding network and connects to the carrier to provide a signal strength
of at least 7 CSQ. While this action is being performed, all four LEDs activate to show a scanning sequence in
progress. The LEDs cycle from top to bottom and then bottom to top until the LE4020/LE4020CF connectes
to a carrier with a signal strength above 7 CSQ (minimum of bottom signal strength LED on solid).

Once this is completed, the LE4020/LE4020CF proceeds to Step 4.
Step 4 - Acquire C24 Communications Programming
The red LED is on solid and the blue LED flashes. The flashing blue LED indicates that the
LE4020/LE4020CF has requested programming from C24 Communications and is waiting for a response.

Once remote programming is completed, the blue LED switches to solid and the LE4020/LE4020CF proceeds
to Step 5.
Step 5 – Receiver Initialization
The red and blue LED’s are both on solid and the signal strength LEDs are off.
Red Blue Blue/Green

When the LE4020/LE4020CF sends a request to communicate with the central station, the top signal strength
LED begins flashing.
