Batteries Used in the Resideo SiXCT Sensors

In this video, Jarrett from Alarm Grid explains how Resideo SiXCT Contacts use lithium 3V CR123A batteries. Each sensor will require one (1) battery. The expected battery life for this sensor is about five (5) years with average use. Once the battery dies, it will need to be replaced with a new one.

The Honeywell SiXCT is a wireless door and window contact designed exclusively for use with the Resideo Lyric Alarm System. The sensor communicates at a frequency of 2.4 GHz, though on a different channel than the commonly used WIFI frequency. One of the best aspects of this wireless sensor is that it utilizes 128-bit AES encryption in all of its wireless communication. This makes the sensor virtually impossible for others to hack or takeover wirelessly.

Like all wireless sensors, the Honeywell SiXCT needs a battery to power its communication with the panel. In this case, the sensor uses a single lithium 3V CR123A battery. The sensor gets a pretty good battery life, as it is expected to be five (5) years with regular usage. Once the battery begins to die and its voltage drops below a certain threshold, the panel will display a low battery trouble condition. This is to let the use know to replace the battery as soon as possible. This occurs when the voltage drops below 2.3V.

When it's time to change the battery for a Honeywell SiXCT, you just need to slide the front cover for the device away from the sensor's back portion. You can then pull the housing apart and access the battery compartment. When applying the new battery, make sure that the polarity is properly observed. You can then close the sensor and put it in its usual location. Make sure to use a lithium battery for the longest possible battery lifespan.https://www.alarmgrid.com/faq/what-type-of-batteries-do-honeywell-sixct-sensors-use
