The batteries in my keypad seem to be draining at a very fast rate.

The expected battery life for the Keypad is typically 12 months, based on arming and disarming the system 3 times a day and triggering an alarm once per month.

However if a substantial amount of programming/operation is performed using battery power, this will reduce the battery life.

It is advisable to use a micro USB adaptor to power the device during substantial programming, setup or operation. A typical 5V micro USB power adaptor such as a phone charger is compatible. Note: the connector is located inside the battery compartment.
