Yes. There are a few different types of batteries in a system. We suggest contacting the monitoring company (Wright-Hennipen) and put the sensor or system into test mode for the length of time you think it will take to change the battery. Remove the battery and take with you to purchase a new one, and install the new battery- paying attention to polarity. Then contact the monitoring company (Wright-Hennipen) to remove the sensor or system from test mode.
