The Honeywell GSM3DB25KT is an AlarmNet antenna kit with a 25’ extension cable. The GSM3DB25KT includes the GSM-ANT3DB weatherproof external antenna that can be added to an AlarmNet cellular alarm monitoring communicator or dual path alarm communicator to increase the cellular signal strength. The GSM3DB25KT also includes every other item needed to connect the GSM-ANT3DB antenna to your AlarmNet alarm monitoring communicator. The 7670F mounting bracket is used to mount the GSM-ANT3DB on a flat surface. The WA7626-CA adapter cable, the K14207LF adapter cable and the 7626-25hc coax cable are the three connection cables used to bridge the gap between the alarm monitoring communicator and the external antenna. The GSM3DB25KT antenna kit has everything you need to add an external antenna to your AlarmNet alarm monitoring communicator.
AlarmNet cellular alarm communicators like the Honeywell GSMV allow you to send your Honeywell security system’s alarm signals to Alarm Grid’s central station via the AT&T cellular GSM network. The cellular alarm communications are wireless and secure. Unfortunately, not every home in America has good cellular coverage. You can check the approximate cellular coverage at your address using the AT&T coverage viewer on AT&T's website. However, just because your address should have coverage, it does not guarantee that your cellular alarm communicator will work properly once installed. There are many things inside your home that can reduce the cellular signal strength and prevent your cellular alarm signals from reaching Alarm Grid’s central station. Lead paint, metal studs, reinforced concrete, and many other building materials can interfere with your cellular alarm communicator. Unfortunately, you will not know the exact cellular signal strength until you have installed the alarm communicator inside your home. By that time, it may be too late to try and choose a better installation spot for better cellular reception. Also, as AT&T has begun to shift away from 2G cellular technology to make room for the faster more advanced 3G and 4G cellular technologies, cellular alarm communicators that used to work great may start having communication issues. If your AlarmNet cellular or dual path alarm monitoring communicator is having communication problems, you will have to add an external antenna. The external antenna increases the gain of the cellular communicator’s antenna and allows you to move the cellular point of reception to the best possible spot. With the GSM3DB25KT antenna kit, you will have 25’ of cable extension so that you can mount your external antenna on the outside of your home and eliminate any cellular interference from within your home.
If you are adding the Honeywell GSM3DB25KT 25’ antenna kit to a Honeywell LYNX Plus GSMVLP cellular alarm communicator or to a Honeywell GSMX VISTA Series cellular alarm communicator, you will also need to purchase the Honeywell GSM-EAA antenna accessory to complete the installation.
