INTRODUCTIONINTRODUCTION
INTRODUCTIONINTRODUCTION
INTRODUCTION
The SK-983A is the ideal keypad for office and home security installations. Itis a self-contained security keypad with a built-in
5A relay for electric door strike and other security and access control applications. With its EEPROM memory, the keypad’s
programmed data is saved in case of power failure. Security is assured with over 100 million possible combinations for the
master, user, duress, and quick codes. Other security features include duress output and a built-in tamper switch. For
convenience, the SK-983A also supports egress input (a push-button switch inside the protected area for easy exit when one-
way security is sufficient).

!12VDC IN — Connect to the (+) and (-) terminals of a 12VDC power supply. The keypad’s (-) terminal is the
grounding point for the keypad.
Important — Connect to a
regulated power supply only.
!DU OUT (Duress Output) — Outputs a transistor ground when the
Duress Code is entered. Connect to activate an alarm control
panel or telephone dialer. Output: Ground (-) output, 100mA,
25VDC max.
!EG IN (Egress Input) — Connect to the 12VDC IN (-) terminal via
a momentary push-button switch. Allows user to bypass the
security code by pushing the push-button switch. This switch is
normally put inside the protected premises near the door to allow
those inside the protected premises to exit without keying in the
code. Leave this terminal open if it is not used.
!O/P RELAY — 5A N.O. dry relay contact for connection to a door
striker. Programmable N.O. or N.C.
Important — Connect
the included 1N4004 diode in parallel to the electric
strike or magnetic lock (see page 4).
!N.C. TAMPER — N.C. contact when the keypad is secured on the
back box. The contact opens when the keypad is separated from
the box. Connect to the 24-hour zone of an alarm system if

To program the SK-983A, you will first need to decide the following information:
- The Master Code and/or the User Code.
- Relay configuration — momentary or shunt, and relay momentary output time (1 to 999 seconds) in momentary mode.
- Whether or not Quick Code is to be used.
- Result of improper code entry after 10 successive tries (30-second code lockout, Duress output, or neither).
Now you can program the keypad as shown in Figure 3.

For convenience in first-time programming, the SK-983A comes preprogrammed with the Master Code 0000. Additional
codes and or data should be programmed at the owner’s discretion. However, to ensure security, the owner should program
a personal Master Code to replace the factory-set Master Code.

In this example, the following data will be stored in the keypad:
- Change the factory Master Code 0000 to a personal Master Code 3289.
- Set the User Code to 8321
- Set the relay output to momentary mode, 5 seconds.
- Set the keypad to lock 30 seconds after 10 consecutive incorrect code inputs.
Programming — Enter the data as follows:
0000* Enter the programming mode using the factory-set Master Code.
03289# 3289 has been stored as the new personal Master Code.
18321# 8321 has been stored as the new User Code.
405# The relay output has been set to momentary mode with 5-second output.
70# The keypad has been set to lockout code entry for 30 seconds following 10 consecutive incorrect code
entries.

AD (EXAMPLES)
The following examples use the sample data programmed above.
Example 1 — Activate the 5A relay with the User Code.
To activate the relay output (for instance, to energize the electric door striker), enter the User Code followed by the “#” key.
8321# The relay output will be active for 5 seconds.
Example 2 — Activate the 5A relay with the Master Code.
Under normal circumstances, the User Code is used to activate the relay. However,if several keypads are programmed with
the same personal Master Code but different User Codes,the relay can be activated by typing in the Master Code followed by “#1.”
3289#1 Relay output will be activated for 5 seconds.
Example 3 — Duress Code.
If a user is being forced by a thief to use the keypad to open a door, he/she can use the Duress Code. This allows a user under
duress to activate the 5A relay and trigger an alarm at the same time. The keypad determines it automatically by adding 2
to the first digit of the User Code. (Example: If the User Code is “1234,” then the Duress Code is “3234.” If the User Code is
“8321,” then the Duress Code is “0321.”) To activate the Duress Output, enter the Duress Code followed by the “#” key.
0321# The relay output will be active for 5 seconds,and a Duress signal is sent to an alarm control device.
Example 4 — Using the Quick Code
The Quick Code, if programmed, allows the keypad to latch the relay ON by keying the first 2 digits of the User Code. To turn
the relay OFF, key in the entire User or Master Code. This is useful when, for instance, the relay needs to be ON during the
day to allow unrestricted access to the protected premises, but OFF during the evening to restrict access. In this example, the
supervisor uses the Quick Code to latch the relay ON in the morning, and the User Code to shut it off in the evening.
