The Honeywell GSM-EAA is an AlarmNet external antenna accessory that is used to connect an AlarmNet GSM-ANT indoor remote antenna or GSM-ANT3DB remote weatherproof antenna to an AlarmNet GSMX VISTA Series or GSMVLP LYNX Plus Series cellular alarm monitoring communicator.
When your Honeywell VISTA Series alarm control panel is upgraded with a GSMX cellular alarm monitoring communicator that is not connecting reliably to AT&T’s cellular GSM network, you will need to get a different point of reception for your GSMX cellular alarm communicator. You can move your Honeywell VISTA Series alarm control panel to a different location within your house that has better cellular reception. However, as the VISTA alarm control panel is housed in a beige metal alarm cabinet and may be connected to hardwired alarm devices, it is not easy or even possible to move the alarm control panel in most cases. Therefore, your other option is to leave the GSMX cellular alarm monitoring communicator in its installed location and add an external antenna which will provide a new point of reception. The GSM-ANT has a 10’ RF antenna extension cable and should be used when a metal object in your home is preventing the cellular alarm signals from transmitting properly so that you can easily move the cellular reception point around the interfering metal object. If you have a L3000 LYNX Plus wireless alarm control panel, upgraded with a GSMVLP cellular alarm communicator, it is much easier to move the alarm control panel to a location with better cellular signal strength as it is a wireless device that just needs to be plugged into a wall outlet. Therefore, the GSM-ANT is not normally used with the GSMVLP. However, when there is no spot in your entire home that provides adequate cellular reception, you will have to try installing the GSM-ANT3DB weatherproof antenna outside of your home and then connect it to your GSMVLP. Unfortunately, the GSMX and GSMVLP cellular alarm communicators, due to their smaller size do not have the needed connector plugs to connect to a GSM-ANT or GSM-ANT3DB external antenna. Therefore, the GSM-EAA external antenna accessory is used to retrofit the GSMX or GSMVLP with the needed connectors.
Before installing the GSM-EAA onto your GSMX cellular alarm communicator, you should disconnect all power to your GSMX. You will then remove the (3) screws that secure the GSMX circuit board and carefully remove the circuit board from the plastic enclosure. Next, remove the (1) screw from the back of the circuit board that holds the internal antenna to the GSMX. Use the hook on the GSM-EAA to attach to the right side of the circuit board and swing the GSM-EAA down into place. Fasten the GSM-EAA to the circuit board of the GSMX using the long screw included with the GSM-EAA. Use the same hole the smaller screw you previously removed was using to secure the GSM-EAA to the front of the GSMX. You then only need to connect the K14207LF adapter cable that came with your GSM-ANT or GSM-ANT3DB to the top of the GSM-EAA antenna accessory and secure the other SMA connector end to the SMA port of the GSMX’s plastic enclosure. Put the GSMX back into the plastic enclosure using the (3) screws previously removed and attach the GSM-ANT to the SMA connector. If you are connecting your GSMX cellular alarm monitoring communicator to a GSM-ANT3DB external antenna you will also need to purchase a WA7626-CA cable and a RF antenna coax cable separately. The WA7626-CA connects to the SMA connector on the GSMX and the RF antenna cable is used to finalize the connection to the GSM-ANT3DB.
Before installing the GSM-EAA onto your GSMVLP LYNX Plus cellular alarm communicator, you should disconnect the ECP cable that connects your GSMVLP to your LYNX Plus alarm control panel. With the ECP cable disconnected, all power to the GSMVLP will be removed. Next you should follow the same steps detailed above for removing the internal antenna of the GSMVLP and replacing it with the GSM-EAA antenna accessory. If you are adding a GSM-ANT to your GSMVLP, you will just need to attach the K14207LF cable and then connect the GSM-ANT remote antenna. If you are adding a GSM-ANT3DB, you will also need to purchase a WA7626-CA SMA-N cable and a RF antenna coax cable.
You do not need the Honeywell GSM-EAA AlarmNet antenna accessory if you are connecting a GSM-ANT or GSM-ANT3DB to an AlarmNet GSMV, VISTA-GSM, iGSMV, or iGSMHS alarm monitoring communicator.
