The Honeywell GSM3DB50KT is an AlarmNet 50’ antenna kit the includes everything you will need to mount an outdoor external antenna to boost the cellular signal strength of your AlarmNet cellular alarm monitoring communicator or dual path alarm monitoring communicator. The GSM3DB50KT includes a Honeywell GSM-ANT3DB weatherproof external antenna which can be mounted on the outside of your home using the Honeywell 7670F mounting bracket which is also included. The GSM-ANT3DB requires (3) connection cables that connect the external antenna to the internal antenna found within your AlarmNet cellular alarm monitoring communicator. The GSM3DB50KT includes all (3) of the connection cables that are required.
First, you will need to to secure the SMA connector on one end of the included Honeywell K14207LF adapter cable to the plastic case of your AlarmNet communicator. Next, you will need to connect the MMCX connector on the other end of the K14207LF adapter cable to the internal antenna of your AlarmNet alarm monitoring communicator. The pin inside the MMCX connector is delicate so be careful while plugging it into the internal antenna port. After you have installed the K14207LF adapter cable, you will need to connect the Honeywell WA7626-CA adapter cable to the SMA connector of the K14207LF. The WA7626-CA has a N connector on its other end and a bracket which you can use to mount the adapter cable to your wall. With the WA7626-CA secured to your wall, you can then add the Honeywell 7626-50HC 50’ coax cable which has a N connector on both its ends. One end of the 7626-50HC connects to the WA7626-CA adapter cable and the other end connects to the base of the GSM-ANT3DB external antenna. Be sure to feed the 7626-50HC up through the hole in the 7670F mounting bracket so that antenna is secured in place. With the GSM3DB50KT fully installed, you will see a dramatic increase in the cellular signal strength of your AlarmNet alarm monitoring communicator. You can check the cellular signal strength by asking your AlarmNet dealer or by looking at the RSSI LEDs on the circuit board of your AlarmNet communicator. The RSSI LEDs are (6) lights; (1) red followed by (2) yellow and then (3) green. If the red LED is on, the device is in the default RSSI mode. The yellow and green lights indicate the cellular signal strength and the more lights that are lit, the stronger the cellular signal. You should not rely on a cellular alarm communicator that does not have at least the (2) yellow LEDs and the first green LED lit up at all times.
The AlarmNet GSM3DB50KT is the most popular antenna kit for improving the cellular signal strength of your dual path or cellular alarm monitoring communicator because it includes the 50’ 7626-50HC coax cable. The GSM-ANT3DB external antenna improves cellular signal strength in (2) ways. The GSM-ANT3DB is a 3dBi gain GSM antenna while the internal antenna of the AlarmNet alarm monitoring communicator is only 1.3dBi. Therefore, just by adding the GSM-ANT3DB, you are increasing the cellular signal strength almost (3) times over. More importantly though, the GSM-ANT3DB allows you to choose the best possible cellular reception point as it is much easier to install the external antenna at the right location than it is to move your AlarmNet cellular communicator to the best point of reception. AlarmNet communicators must be installed inside, while the GSM-ANT3DB is weatherproof and can be installed outside. You will always get a much stronger cellular signal outside your home as many different building materials used within your home reduce cellular signal strength. As the GSM3DB50KT includes the longest coax cable, you have the most freedom to install the GSM-ANT3DB outside your home to get the best possible cellular reception.
Make sure to also purchase the Honeywell GSM-EAA antenna accessory if you plan to use the GSM3DB50KT with a Honeywell LYNX Plus GSMVLP cellular alarm communicator or a GSMX cellular communicator as the GSM-EAA is needed to add an external antenna to each of those Alarmnet communicators.
