1ESL20 Lock Features
The ESL20 Electronic Safe lock has many advanced features used in commercial applications.
These features offer the Supervisor, referred to as the Master User, the ability to manage access to
the safe in many ways. The features are:
1.1 Time Delay:Time delay forces the user to wait a pre-determined time period before the
safe can be opened. This feature is a robbery deterrent, whereby the user can cooperate
with a robber in opening the safe, but forces the robber to wait before access is granted.
The idea is that a robber is too impatient to wait that long and gives up. Time delay
periods are typically set for 10 or 15 minutes. The ESL20 can be set for a Delay Period of
1 to 99 minutes. If a user keys in a valid combination, a flashing of the LED lamp
approximately 2 times per second indicates the Delay Period. At the end of the Delay
Period, a long warbling tone is sounded to indicate the completion of the delay. An Open
Period begins timing after the completion of the Delay Period and is indicated by 4 beeps
and LED flashes every five seconds. During this period, the user must key a combination
and cause the lock to open. The open period can be set for 1 to 9 minutes long. Time
Delay can be canceled during the delay period by pressing “C –(any number key) -#”.
1.2 Multiple Users:Many cash handling methods require that several people have access to the
safe. With an electronic lock in multi-user mode, there is no need for all users to share
the same combination, as is the case with a mechanical combination lock. This feature
also allows the supervisor the ability to control the subordinate users individually and
makes employee turnover easier to manage because individual users can be added and
deleted at will without affecting others. A “Poor Man’s Time Lock” effect can be
implemented daily where the Master User can disable the Multi-User Mode at the end of
the day and then re-enable the mode at the beginning of the next business day. This
causes the lock to reject all the Subordinate User Codes during off-business hours. The
individual subordinate user codes are not lost, just disabled.
1.3 Dual Control:This feature provides for a higher level of security, where two different
combinations are required to open the safe. When set, the lock requires that two users
key their individual combinations, one after the other, before the lock will open. After the
first user keys a valid combination, a short warbling tone is sounded, and the second user
is then required to key a valid code. If no second code is keyed within 10 seconds, the
lock goes to the resting condition and the process must be started again.
1.4 Armored Car Time Delay Bypass:This feature allows Time Delay to be used under
normal access situations, but provides a means to bypass time delay when cash handling
methods require that an Armored Car courier can take deposits without waiting for the
delayed access. It still requires that a valid resident User be present to open the safe.
The Armored Car Code (User 9) can be keyed in first, followed by a valid user code or,
the Armored Car Code can be used during the Delay Period to stop the delay and then
the user can open the lock with a valid code.
1.5 Duress Alarm:This feature requires that one of the optional Expansion Modules
(ESL20EXP1, ESL20EXP2 or ESL20EXP3) be attached to provide electrical connection
to external systems like alarms and monitoring services. The feature allows a user to
secretly signal that they are under duress, or being forced to open the safe in a robbery
situation. When a user keys a combination, finishing with the last number of the
combination 1 digit high or 1 digit low, a one second contact closure of the output relay is
caused. This contact closure is the same as if someone had pushed a “panic” button to
summon help. By signaling secretly at the safe, the user doesn’t risk angering the robber
and possible injury.
1.6 External Control:This feature allows the ESL20 to be disabled and enabled by an auxiliary
device like an Access Manager, Key Switch, external Alarm System, etc. The Expansion
Modules (ESLAC, ESL20EXP1 and ESL20EXP2) provide terminals for external device
connection. When the External Control Mode is enabled and the Lock Enable input loop
is open, the lock will not open when a combo is entered, it will indicate with a quick 4
beep/flash. The Factory Reset Code will clear this condition if it was set accidentally.
1.7 Auxiliary AC Power:The ESL20 can utilize an external power source to operate at
optimum performance with the batteries acting as a backup system in the case of power
failure. This feature requires one of the Expansion Modules, ESLAC (which includes a
transformer) or an ESL20EXP1 or ESL20EXP2 with the ESLTFMR added.
1.8 Subordinate User Control:The Master User has the option of allowing or not allowing
certain capabilities of the Subordinate Users as follows.
a. The Subordinate User changing their own combination.
b. Two Subordinate Users opening the safe in Dual Combo Mode.
c. The Subordinate User authorizing Armored Car Time Delay Bypass.
1.9 Reset All Functions:A function has been provided to reset all the functions to what is
considered “default” settings. It disables all the various modes, deletes all the users, their
codes, and cleans up any unknown settings. This is useful to get a fresh start after
programming has been lost track of or for personnel changes at the Master User level.
2A few things to remember.
2.1 With each keystroke the red lamp on the keypad will flash and a chirp can be heard.
2.2 If 4 (four) incorrect combinations are entered, the lock will go into a “Penalty Lockout” for 15
minutes to prevent trial and error manipulation attempts at opening the lock. The red lamp will
flash once every 5 seconds during the penalty period. If you press any key during the lockout
period, the red lamp will flash with a chirp 8 times rapidly to indicate the lockout condition.
Note that removing power during lockout will only re-start the penalty timing.
2.3 Before keying the combination, be sure that the handle of the safe is in the fully locked
position to allow the lock to open freely.

2.4 If the lock fails to open or acts strange, replace the batteries with good quality fresh alkaline 9-
volt batteries. To replace the batteries, simply turn the keypad housing counter-clockwise to
the stop and pull it away from the base. Un-snap the old batteries and clip on the new ones.
Position them in the pocket at the bottom of the housing and replace it, watching that the wires
are not pinched. You should replace your batteries once a year to prevent corrosion damage
from leaking batteries.
2.5 During any input sequence, if you make a mistake, you can press “C” to clear the previous
input and start over again.
2.6 The ESL20 uses a fixed length 6 (six) digit combination.
2.7 Use only your fingers to key the combination. Sharp objects will result in damage, which is not
covered by the warranty.
2.8 If at any time during opening or combination changing the unit is left without input for 10
seconds, it returns to a resting condition. If this occurs during a combination change, the Old
Combination is retained.
2.9 At any time during opening or combination changing the unit will register the first 5 digits of the
combination into the “buffer” that receives input. The 6
th digit will be the last numeric key
pressed. For example, if your press C-1-2-3-4-5-7-4-5-2-7-6-#the program recognizes only
the C-1-2-3-4-5-6-# input. The last numeric key pressed continues to replace the one prior
until the “#” key is pressed to indicate completion. This is a security feature that allows you to
baffle an on-looker that may be trying to memorize your combination. This is the electronic
equivalent to a Spy proof Dial.
3Users
There are 10 User Combinations possible. The Master User (User 0) is the one and only code that
is allowed to control all the other users, their access privileges and function setting. Users 1-8 are
only active if Multi-User mode is Enabled and the individual User Number has been Enabled and a
combination entered for that user by the Master User.
3.1 User 0: Designated the Master User. Has control over all Subordinate Users and setting of
all functions.
3.2 Users 1 through 8: Referred to as Subordinate Users. They only have access and privileges
as the Master User assigns them.
3.3 User 9: Armored Car Code. This is a special code used only for the purpose of bypassing
the Time Delay. This code will not open the lock alone, only authorize an opening when Time
Delay is active.
4Combination Changing
One of the strengths of an electronic safe lock is the quick and easy changing of the
combination(s). This adds to security because you can change it at will if you suspect your
combination is known by others.
The combination change method for the Primary code (Master User) can be done two ways, with or
without a User Number. All combination changes require and authorization code and two entries of
the new combo as verification.
Note: In the event that Function 60 (Subordinate Combo Change) is set to Disable (F60=0), only
the Master Code will authorize a change.
4.1 Master User Code change: At any time, the Master User combo can be changed by keying:
C -# -(Old Master Code) -# -(New Master Code) -# -(New Master Code) -#
4.2 Multiple User Mode Change and F60=1: Changing of any combination, including the Master
User Code, can be changed by the following sequence:
C-# -(User No.) -# -(Old User Code) -# -(New User Code) -# -(New User Code) -#
4.3 In the event Function 60 is Disabled (F60=0) or you are adding a new User, then the combo
change must be authorized with the Master User’s code:
C-# -(User No.) -# -(Master Code) -# -(New User Code) -# -(New User Code) -#
Combination Change Examples
The Master Combo is 159260 and you wish to change it to 918273. Do the following:
C-#-0-#-159260-#-918273-#-918273-#or C-#-159260-#-918273-#-918273-#
User 5’s combination is 342312 and you wish to change it to 768798
C-#-5-#-342312-#-768798-#-768798-#
User 5’s combination is unknown and you wish to set it to 768798, the Master Combo is 159260
C-#-5-#-159260-#-768798-#-768798-#
5Lock Feature Setting and Function Codes.
The ESL20’s advanced features are controlled only by the Master User, and are set using Function
Codes. A function can be turned on and off, or set, using the Function Code with the Master User
code as authorization for changing or setting the function. A Function Code is a 2-digit code that
associates to a particular setting. Each Function Code has a default, or standard setting, which is in
the lock when there have been no changes or after a Function Reset (F99) has been executed.
They are as follows.
Function Code List Enable=1, Disable=0
Function Function Description Setting Range Default
01 Time Delay Mode Enable/Disable 1 or 0 0
02 Set Time Delay Period 1 to 99 10
03 Set Open Period 1 to 9 5
10 Multiple User Mode Enable/Disable 1 or 0 0
11 Add/Enable a User Combo 1 to 8
12 Disable a User Combo 1 to 8
13 Disable All Users 1

A function is set in the following standard format:
C -# -(2 Digit Function Code) -# -(Master User Code) -# -(Function Setting) -#
↑SGCT ↑SGCT ↑SGCT ↑LGCT
After each “#”, a Short Good Combo Tone (SGCT)will be given, until the last “#” of the sequence is
pressed, at which time it gives a Long Good Combo Tone (LGCT)indicating the successful setting
of a function. Any time during the sequence, if incorrect numbers are pressed, a Bad Combo Tone
(4 short beeps) will sound and the lock will go to rest. A function that has an on/off condition rather
than a numeric setting requires a 1(on) or a 0(off) as the Function Setting.
Note: If a default setting is what is desired, then the setting of that function is not necessary.
5.1 Time Delay Settings (Functions 01, 02 & 03)
5.1.1 To Enable Time Delay:
C -# -01 -# -(Master Code) -# -1 -#
5.1.2 To Disable Time Delay:

Time Delay Setting Example. To set Time Delay for 12 minutes, Open Period to 4 minutes and
the Master Combo is 159260, you must execute 3 function codes as follows:
1. First, Enable the Time Delay with C-#-01-#-159260-#-1-#
2. Then, set the Delay Period with C-#-02-#-159260-#-12-#
3. And finally set the Open Period with C-#-03-#-159260-#-4-#
5.2 Multiple User Settings (Functions 10, 11, 12 & 13)
5.2.1 To Enable Multiple User Mode:

Note:Disabling a Subordinate User does not erase the combo associated to that user, so if you
re-enable that User number it is not necessary to re-enter a combo for it unless you are
treating it as a new user.
Enabling Multi-User Mode and Adding a New User Example. To add a User 3 and set a
combination for that User, the Master Combo is 159260 and set User 3 combo to 121314:
1. First, Enable Multiple User Mode with C-#-10-#-159260-#-1-#
2. Then, Add User 3 with C-#-11-#-159260-#-3-#

6Mixed Operating Modes
Any combination of modes can be active at the same time. Here are some situations that are
possible and how they interact together.
6.1 Dual Combo and Time Delay: Any one valid combo can start the Time Delay, but after the
Delay Period, two different valid combo’s are necessary to cause lock opening.
6.2 Armored Car Code, Dual Combo and Time Delay: Armored Car TDL Bypass only allows the
bypassing of Time Delay. Two valid User codes are still necessary to open the lock even the
when Armored Car Code is used to bypass Time Delay.
6.3 Duress Alarm output will be caused any time the Duress code is entered by any User during
opening or starting of Time Delay. Requires Expansion Module.
6.4 Enabling Dual Combo Mode automatically adds a User 1, even if Multi-User Mode is disabled.
Don’t forget to set a Code for User 1 or there will not be two codes to open the lock.
