Honeywell GSMVLP

Honeywell discontinued the AlarmNet GSMVLP cellular alarm communicator and has replaced it with the GSMVLP4G which is a 4G cellular alarm communicator. The GSMVLP only works on AT&T’s 2G cellular network. AT&T has announced that the 2G cellular network will no longer be supported past the end of 2016. Everyone with an existing GSMVLP should upgrade immediately to the GSMVLP4G to avoid interruptions in their alarm monitoring service as certain areas of the country will experience a loss of 2G cellular coverage even before AT&T’s 2106 sunset.

The Honeywell GSMVLP is an AlarmNet cellular alarm monitoring communicator compatible with the Honeywell L3000 LYNX Plus wireless alarm control panel. Home security systems that use a telephone line to send alarm signals to a central station have a serious security risk. A home telephone line is exposed on the outside of almost every home and all an intruder has to do is cut the line before entering the home. With its phone line cut, the most foolproof home security system is rendered useless as no alarm signals will be sent to the central station.

Honeywell’s alarm communication division, AlarmNet, has been offering alternative communication paths for security systems since 1986. These alternative communication paths offer more reliable and secure options for alarm transmissions. Cellular alarm communicators were first developed as a way to protect your home security system from the risk of an intruder cutting your phone line. The threat of phone line tampering still remains, but now as more and more people are getting rid of their home phone service and relying solely on their cellphones, cellular alarm communicators are more important than ever. The GSMVLP cellular alarm communicator uses AT&T’s wireless GSM network to transmit alarm signals from the Honeywell LYNX Plus wireless security system to Alarm Grid’s central station. You can now have your home security system monitored without needing to pay any extra communications costs or worrying about protecting your phone line.

The GSMVLP cellular alarm monitoring communicator is designed to be installed inside your Honeywell LYNX Plus home security system. There are no connections needed once the GSMVLP has been installed as the cellular communicator transmits all alarm signals wirelessly to the AlarmNet servers which automatically forward the signals on to Alarm Grid’s central station for response.

When using the Honeywell GSMVLP, we recommend installing your LYNX Plus alarm control panel as close to an outer wall of your home as possible to ensure the best cellular signal strength. We also do not recommend installing inside of a closet or basement or near any other electronic devices as these locations can oftentimes interfere with cellular communications. The AlarmNet cellular alarm communicator has a green LED to indicate cellular signal strength so you can determine the best possible mounting location for your GSMVLP enabled LYNX Plus home security system. The green cellular signal strength LED should be lit solid for best reception. If is it only blinking green, marginal signal strength is present. If the green LED is not lit at all, you will need to choose a different mounting location. If your GSMVLP cellular alarm communicator does not have adequate cellular signal strength in any location of your home, you can add an external antenna to get a different point of cellular reception.

You should use the AT&T coverage viewer on AT&T's website to ensure your address has AT&T cellular coverage. If your address shows coverage, that is a good indication the GSMVLP will be able to transmit cellular alarm communications but you still would need to verify transmission from within your home. The Honeywell GSMVLP is compatible with AlarmNet’s Total Connect interactive service which allows you to control your LYNX Plus home security system from any web browser or internet enabled smartphone. If you are interested in the newer Total Connect 2.0 service, your LYNX plus wireless alarm control panel must have revision 20.1 or higher and your GSMVLP must have revision 2.6.42 or higher.
