Honeywell LTE-iV Dual Path Ethernet and Cellular Communicator

Hooking up your new Honeywell dual-path Ethernet and 4G LTE communicator to your Honeywell Vista (or Honeywell equivelent such as ADT SafeWatch Pro or First Alert) is actually pretty simple.  Its just four wires to connect.

Always power down your alarm panel before making any connections.  Unplug the AC transformer from the nearby 110VAC outlet and remove either the RED or BLACK wire from the backup battery in the bottom of the metal control panel box.  Only one wire is required to be removed.  You can confirm power has been removed by checking that your keypad is dark (off).

Dual-Path Models (LTE-iA or LTE-iV)

Step 1 is mounting the communicator. Generally mounting the plastic box next to the metal control panel enclosure is the easiest.  Do NOT place the communicator inside the metal box if you want cellular reception!

Wiring To The Motherboard – Vista P Series Residential Panels

Standard Honeywell Residential Vista P Series security panel include the Vista-10P, Vista-15P, Vista-20P, Vista-21iP, and the SafeWatch Pro 3000. Older panels such as the Vista-20SE etc. wire pretty much the same but have no capability for Total Connect 2 interactive services (remote control). Be sure to check the wiring diagram shown on the control panel’s inside door for your panel model and keypad wiring terminals. 

Vista wiring Diagram 1

Your LTE dual-path communicator is essentially a virtual keypad for Total Connect 2 remote control which is why it connects directly to your panel’s keypad ECP bus.  Its just a four wire connection with 2 wires for 12VDC power and 2 wires for data In and Out.  Use the wiring diagram that matches the control panel you own.  If unsure there is always a wiring diagram on the inside door of your control panel.  Just look to see what four terminals are used to connect keypads.  Use the included transformer and backup battery to power the communicator since this unit draws a LOT of power!

DO NOT REMOVE ANY EXISTING WIRES, JUST ADD THE NEW BLACK, RED, GREEN, AND YELLOW WIRES TO THE APPROPRIATE KEYPAD TERMINALS.

Wiring To The Motherboard – Vista Commercial Panels

Standard Honeywell commercial Vista series security panel include the Vista-50P, Vista-128BP, Vista-128BPT, Vista-250BP, Vista-250BPT and others.  Note only the Turbo series (model end with T) can use Total Connect 2 interactive services (remote control).  Be sure to check the wiring diagram shown on the control panel’s inside door for your panel model and keypad wiring terminals.

Your LTE communicator comes with a 4-wire connection harness.  Plug one end into the bottom left side of the communicator, feed into your control box (make sure the door can still close!) and connect to the four screw terminals shown for keypads.

Communicator Power Up

Power up your Vista panal and the LTE communicator by plugging in the AC transformers and attaching the backup batteries – both in the panel as well as the communicator.

Don’t power down the communicator during this first-time initialization process.

Once the LED sequencing completes the communicator is ready for service!

AlarmNet Registration

We will remotely register your dual-path Ethernet/LTE communicator with AlarmNet once we have the device’s MAC and CRC address.  Registration can also be triggered locally as long as an AlarmNet account has already been created but remote registration is failing.  In this case pressing the Test Message / Registration Switch three times will start the registration process with AlarmNet.

Panel Programming

In order for us to pull your Zone List from your panel and tweak the configuration for Total Connect 2 service please follow these simple steps.  This applies to Honeywell residential P series panels such as the Vista-20P only.

  • Enter Program Mode:  [Installer Code] 800.  You will see “20” displayed on the keypad if successful.  The default Installer Code is 4112.  If your Installer Code is unknown then just power down the panel (unplug transformer and battery) and then power back up.  Within 50 seconds of power up press * and # simultanously on a keypad until “20” displays.
