LTE-IV, LTE-IA, and LTE-IC Communicators – Quick Installation Guide 

For Online Support visit: https://mywebtech.honeywellhome.com/   

General Information and Component Identification 

Congratulations on your purchase of Honeywell's LTE-IV/LTE-IA communicator (LTE-IC 

in Canada).  These communicators send alarms and messages from the security 

system’s control panel to AlarmNet for subsequent transfer to the central monitoring 

station.   
In addition to alarm reporting, they provide upload/downloading capability of Honeywell's 

control panel programming data.  Refer to the 

Installation and Setup Guide

 for the use of 

these features. 
These communicators represent the most innovative communication technology for the 

security industry and use sophisticated encryption to ensure the highest level of security. 
This guide addresses a simple installation using default programming values where 

possible and is applicable for the majority of installations.  For detailed information on 

UL, ULC, and configuration of remote services, please refer to the appropriate 

Installation and Setup Guide

 for the product.  The LTE-IV, LTE-IA and LTE-IC are 

henceforth referred to as the communicator or communications module. 

  The communicator requires an AlarmNet account.  For new installations, please 

obtain the account information from the central station prior to programming. 

  For control panels that do not support ECP, refer to the installation guide to use Zone 

Trigger Mode. 

  The control panel treats the communicator as an ECP device, so ensure to program 

the control panel with the communicator’s device address.  Refer to the control 

panel’s 

Installation and Setup Guide

 for details. 

REMOTE SERVICES  

Honeywell offers secure web based services that enable users to remotely monitor and 

control their security system.  These web services enable users to; monitor and control 

their security system from a website or smartphone, receive email notifications of system 

events, and receive event confirmations. 
Dealers can enroll their customers for "Remote Services" by using the AlarmNet 360 

website.  Once enabled, the specific programming fields associated with these features 

can be programmed into the communications device either remotely using the AlarmNet 

360 website or locally using the 7720P programming tool. 
 

Due to Honeywell's continuing effort to improve our products, your device may look slightly different than 

pictured.

1. Determine Signal Strength and Select a Location 

The communicator must be mounted indoors.  When choosing a suitable mounting location, 

understand that signal strength is very important for proper operation.  For most installations 

using the internal antenna, mounting the unit as high as practical, and avoiding large metal 

components provides adequate signal strength for proper operation.  
In this step, you will use the communicator to determine signal strength in order to find a 

suitable mounting location. 

 

LTE-I Initial Power Up

: Upon initial power up, the communicator LEDs blink in repeated 

sequence from top to bottom indicating network initialization. 
Green (REG) 

 Yellow (TX/RX) 

 Red (FAULT) 

This sequence may take up to 15 minutes. 

Do not reset power during this time.

  

When initialization is complete, the Signal Quality display LEDs will light and the yellow and 

red LEDs may blink (per their respective functions). 

After initial network setup, subsequent resets or power ups can take up to 90 seconds. 

 

Note: Read and follow the RF Exposure notice on the other side. 

1.  Unpack the communicator and open the case by pushing in the two bottom tabs with a screwdriver 

while separating the case front. 

2.  Temporarily connect the AC transformer or battery to the communicator.  
3.  Choose the installation site with the 

best signal strength

 by observing the signal quality bar 

graph.  Signal strength should be within 2-5 bars.  The best signal strength is usually found at the 

highest point in the building, near a window.   

4.  Mark the location for the communicator.  

2. Mount and Wire the Communicator 

1.  Locate the case back over the selected mounting position such that the opening in the case 

back is aligned with the wire/cable opening on the mounting surface.  

2.  Pass the wires/cable through the opening in the case back, or route through the removable 

side  knockouts  located  on  the  back  cover.    Then  secure  the  case  back  to  the  mounting 

surface using four screws (supplied).  Make the following connections:

3.  When all wiring has been completed (including the Internet cable if used), attach the case 

front.  Position the top first, then press the bottom section until it snaps in place.  Secure 

bottom using the supplied cover screw.  (Required for UL installations.)

 

4.  You may power up the communicator and control panel.

3. Connect the Internet Cable  

Connect one end of the Ethernet cable (Category 5) to the communicator’s RJ45 Ethernet 

connector and the other end to the cable/DSL router as shown in the figure.  

 

UL

 

  For UL installations, the Ethernet connection between the communicator and 

the router cannot exceed 12 feet.  Both units must be located within the 

same room. 

  Use a Listed cable/DSL router suited for the application.
