Ademco SA5140-1 - Battery Harness Kit Reviews
Submitted on 07/25/2019 Alarm Grid
We strongly recommend the Ademco SA5140-1 for anyone who wants to use a second backup battery with their Honeywell VISTA Alarm System. This convenient and easy to us wiring harness will allow you to connect two (2) backup batteries with the panel by wiring them in parallel. This will effectively double the battery life for the system. This is perfect for users who may experience frequent electrical outages. It is also great for users who want to ensure that their VISTA Panel will remain powered on for an extended period of time when the electricity is out, without having to rely on a power generator. Another excellent feature of this harness is that its positive legs have an inline fuse to prevent damage in case of a power surge.
Our technicians have found that it is easy to use the UltraTech 1240 4Ah Batteries and the UltraTech 1270 7Ah Batteries with the Ademco SA5140-1 Battery Harness. However, you should have no problem using this device with any of the similar sealed lead acid batteries that are compatible with hardwired alarm systems. Just be aware that you may have trouble fitting multiple batteries into your panel's metal enclosure. This will depend on the size of the metal enclosure and the size of the batteries. If that is the case you can always get a second enclosure to secure the batteries. Just make sure that the batteries are wired correctly at the panel in parallel.
Overall, the Ademco SA5140-1 is a great product. While it's not going to be useful for every VISTA user, those who can benefit from a second battery can put this accessory to great use. We believe that this is a fine battery harness to use with your Honeywell VISTA Panel if you intend on using two (2) separate backup batteries. Just be aware that it will take slightly longer for your batteries to obtain a full charge, as more power will need to be stored.
