A. To program the keypad for Quick Code:
3289* The keypad is now in the programming mode, ready to receive new data.
42# Set the relay to latch ON when the Quick Code is inputted.
* Exit the programming mode.
B. Now the relay will be latched ON when the first 2 digits of the User Code are inputted. The relay will be deactivated
when the entire User Code is inputted:
83# Relay output is latched ON (activated).
8321# Relay output is latched OFF (deactivated).

INTRODUCTIONINTRODUCTION
INTRODUCTIONINTRODUCTION
INTRODUCTION
The SK-983A is the ideal keypad for office and home security installations. It is 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).
TERMINALSTERMINALS
TERMINALSTERMINALS
TERMINALS
! 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
necessary.

! RED — Lights ON when the first digit of the entry code is pressed. Remains on for 10 seconds, during which time the
entire code must be entered. If the entire code is not entered while the red LED is on, the entire code is canceled, and
must be entered again from the first digit.
! AMBER — Program status indicator. Synchronized with the built-in buzzer’s tone (see Figure 1).
! GREEN — Lights ON when the 5A relay makes contact.

DAP JUMPER (SYSTEM RESET)
If the personal master code is forgotten, use the DAP
jumper to override the forgotten code and permit
direct entry into the programming mode as follows:
1. Disconnect the power supply.
2. Switch the DAP jumper from OFF to ON.
3. Reconnect the power supply. The keypad will start
beeping.
4. Switch the DAP jumper back to the OFF position.
The keypad will stop beeping.
5. The keypad is now in the programming mode,
ready to receive new data.
6. Re-program the keypad as shown above, starting
with the personal master code.
