Interlogix Caddx 600-XTI-BAT Simon Xti Bat 6Vdc/21 Oomah Nimh

Hey, DIYers. I'm Jorge from Alarm Grid. Today, we're going to be talking about the backup battery for a Simon XTi and Simon XTi 5. Today we're actually going to be working with the Simon XTi. It is still the same if you have the XTi 5. The only difference is the front looks a little bit different, but the backup battery is still the same. Now the backup battery, the way that works is whenever your system loses AC power, the backup battery is what continues to keep your system powered on. If you have the system monitored because you have a cellular communicator in the system, the system will continue to send signals out even if the power goes out. First of all, because it's powered on by the backup battery, and second of all, because it's using cellular connection to send out those alarm signals. Now the backup battery in the system usually keeps the panel powered on for about four hours
