    Item Overview

    This GSM Dialer is compatible with most security systems. Simply purchase a GSM SIM card from an authorized cellular service provider, insert it into the dialer, and connect a standard phone line from your alarm system into the GSM Dialer.

    This GSM Dialer works just like a landline telephone, but it creates a standard phone line using a cellular connection. This device is perfect for those who don't have a telephone landline. This GSM Dialer is also great for added security since it makes it impossible for a burglar to cut the phone line outside of your business or residence.


    If your alarm system has the capability to call you directly over a standard landline, then your alarm will work with this GSM Dialer. Simply remove the standard telephone line from your existing landline or VOIP phone port and plug it into the phone port on the GSM Dialer.

    Your alarm system must have the capability of programming phone number(s) and recording a message directly into it. You cannot program phone numbers or record a message directly into the GSM Dialer. The GSM Dialer simply acts as a phone line for the alarm to call out on.

    Professional Monitoring:

    This GSM Dialer is intended for VOICE DIALING, but will also work with Ademco Contact ID, data tones, that are compatible with professional monitoring.

    Disclaimer: If used with Professional Monitoring Disclaimer: Just like all digital VOIP phone lines, cellular service may also cause Contact ID (used with professional monitoring) to fail, not reporting the alarm condition. Most alarms are programmed to retry in the event of a failure. However, the re-attempt(s) may also fail, causing no signals to be transmitted and no response to be taken from the central monitoring station. By purchasing this unit, you agree and understand the risks involved with using this cellular dialer with Contact ID, or any form of professional monitoring.


    LED Display:
    This GSM Dialer has very easy-to-read LED lights. The cellular signal strength is shown by 4 led lights. (1 light means low signal; 4 lights mean highest signal.) It also has led indicators to let you know when the device is powered on, when the device is dialing, and when the phone call has been established. It also has a module and SIM led light.

    Automatic Reset: New!
    To help prevent interruption of service, this GSM Dialer is equipped with an automatic reset feature. This feature automatically resets the dialer if it looses cellular service, can't find a signal, or fails.

    How Does it Work?

    1. Purchase a regular SIM card from any provider (make sure the provider has a signal in your area!)

    2. Connect a standard phone line to the telephone line port on the back of the GSM Dialer.

    3. Plug the antenna into the jack on the back of the GSM Dialer.

    4. Insert a SIM card (sold separately) into the slot on the back of the GSM Dialer.
