BATTERY INFORMATION
THE E72K-A IS SHIPPED WITH 4 “AA” ALKALINE BATTERIES: The life span has been tested in two different ways. The first test was
performed to see how many operations could be performed repeatedly before a failure. The test averaged 150 thousand operations. The second test was
performed over time for normal operations. This test revealed the the E72K-A batteries would last approximately 4 years at 80 -90 thousand operations.
Using the factory settings, the lockset is set for optimized power usage.
CHANGE THE BATTERIES: The batteries should not be disconnected longer than 10 minutes or there is a risk of affecting the lock’s memory.
IT IS RECOMMENDED TO USE ONLY ALKALINE BATTERIES: The alkaline battery has a gradual curve in the drop off voltage. This curve
determines the power settings for the two stages of battery warnings and the Fail Secure settings. A lithium battery differs from an alkaline battery in the
life cycle of the battery cell. A lithium battery has a very sharp drop off voltage, going from fully charged to a dead cell quickly. This make monitoring
the voltage settings impossible.
TWO STAGE LOW BATTERY WARNING: The E72K-A has a two stage low battery warning. The First warning stage will add a double beep and
Red LED when the user enters their code. The second warning stage will be a double beep every hour. BATTERIES SHOULD BE CHANGED
IMMEDIATELY. Double beeps will occur until the batteries fail.
