Simon XT - What should you do, when you receive a low system battery alert

If your Simon XT is beeping due to a "System Low Battery", or you received a call/email about a low battery from the Central Station, here are the steps to resolve the issue.

Step 1 

The first step is to check the panel's status and verify that you have a "System Low Battery". Note: If your panel is reporting an "AC Power Failure", then you will need to fix the power failure before you troubleshoot the low battery.

 Step 2

If you recently installed the system, or had a power failure, you can run a "Sensor Test" to try to clear the low battery warning.

Follow the instructions below...

Step 3

If the previous steps did not clear the "Low Battery Message", or if it comes back again, you can check the battery voltage by holding down the number "6" on the panel. If the battery voltage shows 1.00 V, most likely the battery is disconnected and you will need to check the battery connections. Next, give the battery 24 hours to charge.

If it still shows the "Low Battery Message" after 24hrs, you will need to replace the battery.

  • Wish the battery would have lasted a little more than 15 months, but was very inexpensive to replace. I love having my alarm system from SafeMart. All the parts are readily available if you need anything. The How To videos are great as well. Saved a bunch of money, customized the alarm the way I wanted, and when it needs to be fixed, I do it myself.

  • Hi Richard,

    I am glad to hear that you are happy with our service! It's unfortunate that the battery in your system did not last as long as it was supposed to; typically the backup battery in the Simon XT/XTi lasts about 3-5 years (depending on use). Fortunately, the vast majority of our customers don't experience problems with the backup battery on the Simon system. If you have any other questions, please let us know or search our Help Center!

  • Hi,

    My Simon XT was installed in July 2011, and the 'Low System Battery' came up last night. I just checked the voltage which showed 5.13V. Do I need to replace it? Is it still under warranty?

     

  • I have the above issue and press six and nothing happens. Is there another way to check the volt?

  • Hi,

    My Simon XT has been in use about 4 years and we got a low battery message this morning.  I tested it using the "6" key like you suggested, and the battery shows 6.63v still.  You don't say what the minimum rating should be on the voltage of the battery before replacement.  What should it be, and at what voltage does the simon xt start dinging you to replace the battery?

     

    Thanks!

  • Never did see a reply on what voltage should be

  • The voltage should be somewhere around 6.5 V typically. The control panel will start giving you the low battery trouble if it is below 5.4 V or if the battery is wearing out and not holding the charge like it should. If the voltage is above 5.4 V and you have already done the sensor test and the low battery message will not go away, then the battery is probably not holding the charge properly and needs to be replaced. You can unplug the power supply for a few minutes and check the voltage again to see how quickly the voltage drops when running on battery.

  • Thank you so much for your blog!!! Saved me! My system is good to go!
