• Battery brand
• Access credential settings (PIN, Prox Card, or both)
• Lock settings
In ideal conditions, you can expect up to 120,000 openings using four “AA” Alkaline batteries.
A flash of both red and green LEDs identifies a low battery condition when a valid credential
(PIN, Prox Card, or both) is presented, and the lock will still open. When you observe a low
battery condition, the batteries should be replaced as soon as possible.
Battery Pack Replacement
Always replace all 4 batteries in the pack with good quality, AA alkaline batteries. If you
replace the batteries within 2 to 3 minutes, the lock will continue working as before, granting
and denying access to users based on their access schedules.
If the battery replacement time is longer than 2 to 3 minutes, you may lose the current date
and time of the lock, even though all the user and lock configuration parameter information
will not be lost. When the lock loses its date/time, all of your access schedule times will be
out of sync, thus denying access to valid users. In this case, you MUST update the lock’s
date/time with the current date/time in the M-Unit.
You can do this simply by putting the lock in Communications Mode (enter the 900#
command on the lock keypad and tap Program on the M-Unit screen) and then tapping
Close. On the E-Plex ACS Diagnostics screen of the M-Unit, tap Sync Clock. The M-Unit
screen will refresh and displays the correct date and time. Tap Close to exit the Diagnostic
program, and then tap Disconnect to end communications.
Important: Please ensure that your M-Unit’s current date and time are set correctly before
synchronizing with the lock. If you forget to update the date/time, the lock will keep flashing
the red LED every 8 seconds as a reminder until the lock’s date/time is updated.
Note: In rare instances, when you reconnect the lock with new batteries, the lock may not
re-initialize properly; a typical symptom is that the lock does not recognize any pushbutton
input. If this happens, disconnect the battery pack, press any one of the pushbuttons for a
minimum of 2 seconds to discharge the built-in circuit capacitance, and then re-connect the
battery pack. Wait a couple of seconds until you see the green LED flash once, followed by
the sound of the motor crunching and a high pitched beep indicating that the lock has re-
initialized properly.
Sequence of Operations
This section describes the sequence of operations for accessing and programming the E-
Plex 5200/E-Plex 5700 lock.
With the E-Plex 5200/E-Plex 5700 in the Factory Mode:

default “Entry” function.

on changing to the desired BHMA lock function.
