Alkaline Batteries
The 4000 Series lock low battery indicator consists of an advance visual and
audible warning—alternately flashing green and red lights and a low-pitched
beep every half a second in sequence with the flashing red light. The indicator is
activated when a valid access code is entered and lasts for the unlock time or until
the lever is released after unlocking. The lock will continue to function until the
batteries are completely discharged.
Warning: The batteries used in the lock must be alkaline. Non-alkaline
batteries can cause the lock to fail.
Replace the factory-supplied AA alkaline batteries (1.5 Volts x 4 = 6 Volts) with
four new, over-the-counter AA alkaline batteries as soon as possible:
1.
Remove the two screws that secure the battery pack plastic cover to the
bottom of the backplate of the inside housing using the
5
⁄
64
" (2mm)
Allen key.
2.
Slide out the battery holder containing the sealed battery pack.
3.
Slit open the sealed battery pack with a knife and replace the old
batteries, while observing the polarity (+ and -) of the batteries as
marked on the battery holder.
4.
Slide the battery holder back into place, ensuring that the circuit
connection is intact.
Note: The battery pack casing (the side with the sharp corners) should
face the door, and the battery pack (the side with the rounded corners)
should face out—away from the door.
5.
Reinstall the plastic cover with the two Allen screws.
All lock codes and setup information remain intact in the lock memory for up to
ten years while the power is disconnected. If the lock is in passage mode when
the low battery indicator is activated (the battery is low and the lock is alternately
flashing red and green lights), the lock reverts to normal locked mode when the
batteries are replaced. Test the lock to ensure that it operates properly.

Security
•
Change the Master authorization code to an eight-digit code
(command code 299) other than the factory default 12345678. Record
the new code using the “
Code Record Log Sheet for the 4000 Series
Lock
” described in the section 6.2.1 “Code Record Log Sheet”.
•
The mechanical override key is provided for use as an emergency key
only and should be stored in a secure location. However, the key
should be readily available to authorized personnel when it is required
in an emergency unlock situation.
•
For utmost security, select the maximum length of six digits for all User
and Service access codes. The number of possible unique access codes is
increased to 1,000,000, reducing the chance of someone correctly
guessing the combination.
•
If there is concern within your facility regarding illegal attempts to
guess access codes, select the maximum tamper shutdown time of 15
minutes. Note, however, that the lock is shut down for the entire time
period, regardless of whether the attempts were legal or simply invalid.
In the tamper shut-down mode, the lock can only be unlocked using
the mechanical override key or remote unlocking.

Code Record Log Sheet
Photocopy the
“Code Record Log Sheet for the 4000 Series Lock”
printed on
the last page of this manual. Use this sheet to record all authorization and access
codes and all current setup parameters for the lock. Store it in a secure location.
Perform this task for all 4000 Series locks in your facility so that a complete
hard-copy record for all locks exists for easy maintenance.
