Batteries; Low Battery Indicator - OSI Security Devices OMNILOCK OM100 Series User Manual

Chapter 8
Four AA-size 1½-volt alkaline batteries power the System. You can expect
them to last for approximately 5 years or: 100,000 operations for Cylindrical
Locks, 100,000 operations for NT Falcon Mortise locks, 80,000 operations
for Schlage mortise locks, or 150,000 operations for Wall Mount Systems.
Each time you enter the Master or a Submaster code, the System flashes the
lights according to the condition of the batteries as follows:
Light Flashes
Grn-Grn-Grn
Grn-Grn-Red
Grn-Red-Red
Red-Red-Red
† The Battery Level appears in the log on header and some reports.

Low Battery Indicator

When the battery status declines to level 1, the System will alert the User
upon each entry by flashing the battery level indicator (Grn-Red-Red)
instead of the single green Light.
If the battery status is allowed to decline to 0, the System will indicate the
replace battery condition (Red-Red-Red) and will deny access to all but the
Master Code (access level is set to Low Battery Shutdown).
The Low Battery Shutdown feature reserves some power for memory
retention so that programming will not be lost. Replace the batteries as soon
as possible.
