Battery Information
THE I-QUE IS SHIPPED WITH 4 AA ALKALINE BATTERIES.
The life span of the batteries 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 that the i-Que batteries would last approximately four years at 80 - 90
thousand operations. Using the factory settings, the lockset is set for optimized power usage.
Changing the Batteries
When the batteries need to be changed, you will have 10 minutes to remove the old batteries and install the four
new AA batteries, before memory is effected.
IT IS RECOMMENDED TO USE ONLY ALKALINE BATTERIES,
due to the predetermined power settings in the lock. 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 makes monitoring the voltage
settings impossible.
Two Stage Low Battery Warning
The i-Que has a two-stage low battery warning.
The
first warning stage
will add a
double beep and yellow 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.
To ensure the lock fails in a locked or unlocked mode, use Function 36 Fail Secure page 7 or the lock
will fail in the last state, either open or closed.
The batteries can also be checked manually using Function
17 Battery Status Check above.
