A cell phone network intercom uses cell phone service at the intercom location to call any landline or mobile phone number. The intercom works in the same way has any mobile phone, however it also has some special features, which you can read about here: cell phone intercoms

Installation of a cell phone network intercom consists of these tasks:
  1. Ensuring you have good coverage where you want to install the system.
  2. Inserting and activating the SIM card that comes with the system.
  3. Connecting the 24-volt power supply.
  4. Connecting two wires to your gate controller or electric door strike.
  5. Programming resident data into the system.

1. Cellular Coverage

signal level testPrior to installing this system, it is crucial to ensure adequate cellular coverage in the intended installation area. We highly recommend conducting a thorough site survey to assess cellular reception on-site. If reception is deemed poor in the vicinity, we do not recommend proceeding with this system installation unless you want to use a cell phone signal amplifier. As a preliminary check, individuals with cell phones compatible with AT&T or T-Mobile networks can assess signal strength by visiting the designated area and examining the bars displayed on their phones. It's advisable to confirm if at least two bars are visible and if calls can be successfully made.

Furthermore, the system is equipped with status LEDs that visually indicate signal strength. Additionally, the accompanying programming application facilitates the request of signal strength readings directly at the intercom unit.

2. Installing the SIM Card

The system comes with a NANO SIM card along with activation instructions. If you prefer to use a different SIM card, it must also be nano-sized. The alternative SIM card should be a standard voice, SMS, and data NANO-sized SIM with a minimum 1GB data allowance and compatibility with 4G service. Do not use a data-only SIM card, which is intended solely for tablet PCs and will not function in the unit. For making voice calls on a 4G system and to ensure optimal service, your SIM card and provider should support VOLTE (Voice over LTE). All major US carriers support VOLTE.

SIM installationTips for Alternative SIM Cards:
  • Ensure the SIM card has calling credit and can make and receive calls on a mobile cell phone (pre-paid).
  • Confirm that the SIM card is not locked to a specific phone and can be used in other devices.
  • Verify that the SIM card does not require a PIN code.
  • Disable voicemail service on the SIM card.
Note: Some IoT SIM cards or specific networks may not function as expected. It's recommended to test using a reputable network.

If you opt to use the provided SIM card, please follow the instructions provided with the SIM's serial number.

3. Power Supply Connections

All cell intercoms come with a 24v DC power supply that connects via two wires to the intercom connections labeled "24 In". Alternatively you can use a 24Volt DC solar panel system that is rated for at least 30 watts like this one: 24 Volt, 30 Watt Solar Panel System

It is advised to install a grounding rod to the Earth Rod connection to help protect the unit from static electricity and lightning.

4. Gate and Door Opener Connections

All the cell intercoms have two relay connections. A relay is a switch that can control electric door strikes, gate controller motors, and any other electric device that needs a switch closure. As such a switch can control any type of door strike or gate opener, no matter what brand. You simply run two wires from the intercom over to the door or gate. Where you connect those wires will vary depending on the device so you will need the wiring diagram for your device. If you currently have a button, keypad, or wireless open button that opens the gate, you can connect the intercom to the same wire terminals. In the intercom App there is a button for each relay so they can be activated separately.

5. Programming Resident Data

The cell intercoms come with an Android or an Apple iOS App you use to program the intercoms. How the App looks will depend on whether you have a single-residence intercom or a multi-tenant intercom. All functions are programmed through this app and can be done remotely. Below is an example of some of the screens for the multi-tenant app.
