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

complete.

Step 2 - Determine the Best Signal Location

Detach the front cover by removing the four screws.

Apply power (DC and/or battery). The LE4020/LE4020CF is now in Placement Test mode.

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.

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 con-

nected to a carrier with sufficient signal strength (minimum of bottom signal strength LED on solid), it pro-

ceeds 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.

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 part-

ners) 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

3G4010/LE4010 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 pro-

ceeds to Step 5 .

Step 5 – Receiver Initialization

The red and blue LED's are both on solid and the signal strength LEDs are off.

When the LE4020/LE4020CF sends a request to communicate with the central station, the top signal

strength LED begins flashing.

When the central station communicates back to the 3G4010/LE4010, the top signal strength LED turns on

solid.

When the LE4020/LE4020CF sends a request to communicate to the next central station, the bottom signal

strength LED begins flashing...

...and turns on solid when it receives a communication back from the central station.

If at least one of the central stations does not respond back to the communicator, the signal strength LED

corresponding to that central station turns off. Once the initialization sequence is complete, the

LE4020/LE4020CF switches to steady state operation.

Step 6 - Mount the LE4020/LE4020CF

Power down the LE4020/LE4020CF by removing the DC power source and battery leads.

Using the cabinet, mark the four screw locations. Drill the anchor screw holes.

NOTE: Check for cable conduits and water pipes before drilling.

Using anchor screws (not provided), mount the cabinet to the wall.

Run the cables through the cable entry [13] or through the cabinet knockouts.

Complete the connections on the terminal blocks [11].

NOTE: Ensure that power and Telco circuit connections are made only after the cabinet has been secured to

the building or structure, and has been connected to the protective earth ground. Descriptions of the ter-

minals can be found in the 'Connecting the LE4020/LE4020CF' section.

Reattach the front cover [1] securely to the cabinet.

NOTE: Please refer to the end of this manual for wiring diagrams.
