Introduction
About the Mini-Key System
This system is a self-contained, standalone keypad to control a door or gate. A four or five digit customized
personal identification number (PIN) is assigned to an individual (or group of individuals) for controlled access.
The system also supports a remote keypad for access control of a second door or gate.
Key Terms
As you read through this manual, you may encounter unfamiliar words or terms associated with Mini-Key. This
section defines some of them for you.
Dealer/Installer
This person sells and installs the system and may
have programming access.
Gate or Door
Used synonymously throughout the manual, these
terms refer to controllable entry/exit areas of the
complex, normally a gate or door.
Manager
This person manages a complex and/or programs the
system.
Relay
A device that responds to an electric current by
activating other devices, allowing the system, for
example, to lock or unlock a door/gate.
Tenant
Person occupying and/or who has entry access to the
building or complex that is controlled by a Mini-Key
system.
Unit
The unit houses the Mini-Key’s core components. The
Mini-Key can only be programmed at the unit via the
keypad.

Programming Overview
Important: The Mini-Key comes preprogrammed with factory settings. When the system is first
installed, you do not need to program each feature. Review the system’s factory settings before
programming (see page 8). You may want different settings than those already defined.
Programming Basics
All programming occurs with the system's main keypad including sites that utilize the remote (second) keypad.
S
TEPS REQUIRED TO PROGRAM THE MINI-KEY
Each programming command consists of the following:
! 1-digit Programming Step Number
! One or more Data Fields
! Pound Key (#) to Save Data
Programming Step Number:
“3” to Set the Maximum Number of Keypad Errors (Strikes and Out).
Data Field:
The new number of maximum keypad errors will be “4”.
Pound Key:
The last pound key (#) saves the data.
W
HEN YOU MAKE AN ERROR DURING PROGRAMMING
If you realize in the middle of an entry that you are making a mistake, press .
S
YSTEM FEEDBACK
The Mini-Key provides audio feedback through a series of beeps as you program. These are described below:
Programming step was valid.
Duplicate entry code was entered or code not available to delete. Also
used in normal operation to indicate invalid entry due to timezone
restrictions.
Unit has reset or is powering up.
Exited the programming mode.
Entry code is accepted and access is granted.

! ! ! Programming Overview

Entering Programming Mode
The first step in programming the system is to enter programming mode. Once you are in programming mode,
the system will remain in this mode until you tell it to exit to the “run” mode, or until 60 seconds pass without an
entry on the keypad. If the system does not emit any beeps, the keypad may be locked by the "strikes-and-out"
feature (refer to page 5). Wait 3 minutes and then try again.
1. Press .
2. Enter the (6) six-digit password. The default is .
3. You will hear two short beeps when the system enters the program mode. The unit is now ready to accept
programming instructions.
Important: After entering programming mode for the first time, we suggest you change the password
to maintain the security of your system (see below).
Changing the Password
This programming step allows you to change the unit’s programming password so that only authorized
personnel may have programming access. Make sure to write down the new password so you can re-enter
programming at a later date. Factory Setting: 000000
1.
2. New Password (6 digits)
3.
Example: 9 + 123456 + #
Changes the programming password to “123456”.
Verifying the Password
Verify the password entry to ensure proper setting. If the password entered is correct, two short beeps will be
emitted from the system. If it is the incorrect code, the system will emit one long beep. If the unit responds with
an error tone, do not exit programming. The number that you entered does not match the password. Repeat
programming step #9 (see above).
1.
2. Password (6 digits)
3.
Example: 4 + 123456 + #
Verifies if the unit’s programming password is “123456”.
Exiting Programming Mode
To exit programming mode, press . You will hear 5 short beeps if you successfully exited
programming mode.

Initial System Setup
Setting the Entry Code Length
If you decide to change the entry code length after the initial programming, you will need to delete all of the
entry codes before changing the code length. Once you change the entry code length, the old codes will no
longer be valid and cannot be deleted. Factory Setting: 4 digits
1.
2. New Entry Code Length (4 or 5)
3.
Example: 8 + 5 + #
Changes entry code length to “5” maximum digits.
Setting the Relay Activation Time
This tells the system how long to activate the relay that unlocks/opens your door or gate.
Factory Setting: 10 seconds
1. for the Main Relay OR for the Auxiliary Relay
2. Number of Seconds (2-255)
3.
Example: 1 + 15 + #
Sets the main relay’s activation time to “15” seconds.
Note: If this relay activates a gate operator with a momentary contact closure, set the relay activation
time for a short period (for example, 2 seconds). A longer activation time might cause the gate to
repeatedly open and close until the activation period has expired.
Setting the Maximum Number of Keypad Errors (Strikes and Out)
This feature prohibits unauthorized persons from guessing an entry code. Anyone entering an entry code will
have a set number of times to correctly enter his/her code. Each time the code is entered erroneously, it is a
“strike”. After x number of “strikes”, the system will disallow keypad entries at the unit for 3 minutes.
Factory Setting: 5
1.
2. Maximum Number of Errors Allowed (0-10; 0 = Disable)
3.
Example: 3 + 3 + #
Changes the maximum number of keypad errors to “3”.

Entry Codes
About Entry Codes
Entry codes are programmable, numeric codes (4-5 digits in length) that allow entry or exit through a gate/door.
Tenants enter their assigned code onto the Mini-Key’s keypad to prompt the system to grant access.
Entry to
Building/Complex
Mini-Key Unit
The programming sequences described in this section define which entry codes can gain access. Keep track of
what entry codes you have added to the system and to whom they have been assigned. This will allow you to
void a code to prevent future access to the building or complex. The MINIKEY has a capacity for 500 entry
codes.
M
INI-KEY TIMER
The MINIKEY system supports an input from an external timer. This feature provides the ability to restrict
certain entry codes from gaining access during a specified time. Consult the installing dealer for information if
this option is required but not implemented.
! Enter Timer Code “1” if you want an entry code to be restricted during the specified time.
! Enter Timer Code “0” if you do not want an entry code to be restricted.
E
NTRY CODE SPECIFICATIONS
Entry codes are factory set to 4 digits long.
! 4-digit code range is 0000-9999.
! 5-digit code range is 00000-99999.
Adding an Entry Code
1.
2. Entry Code (4 or 5 digits)
3. Relay Code (1-7; see note below)
4. Timer Code (0 or 1; see note below)
5.
Example: 5 + 6666 + 1 + 0 + #
Sets code “6666” to cycle relay 1 for the activation time regardless of timer settings.

! ! ! Entry Codes

Doc 6001050, Rev E
1 = Cycle Relay 1
2 = Cycle Relay 2
3 = Cycles Both Relays
4 = Release Both Relays
5 = Toggle Relay 1
6 = Toggle Relay 2
7 = Toggle Both Relays
Cycle Relay: When someone enters a valid entry code, the relay will
energize for a set period of time (see page 5), then de-energize
(deactivate to re-lock the door). If the relay is normally energized, then
it will de-energize for the set time and then re-energize.
Release Relay: Returns relay action to default setting. If a relay is
toggled to stay energized (door is unlocked), releasing the relay will
de-energize it (door becomes locked).
Toggle Relay: Energizes a de-energized relay (or de-energizes an
energized relay) until released or toggled.
! Enter Timer Code “1” if you want an entry code to be restricted during the specified time.
Enter Timer Code “0” if you do not want an entry code to be restricted.
Deleting an Entry Code
1.
2. Entry Code (4 or 5 digits)
3.
Examples: 6 + 1234 + #
Deletes entry code “1234”.
Deleting ALL Entry Codes
This programming step will delete all the entry codes from the unit’s memory.
Important: Once you delete the codes, you cannot retrieve them.
