When the reed jumper is in place (default), the door sensor input is bypassed.
To enable the door sensor input, place the reed jumper on one pin only.
When the door sensor input is enabled, connect the COM (-) terminal
and REED terminal to a N.C. contact. The keypad will deactivate
output #1 whenever the contact is opened and closed, working as an
anti-tailgating feature.
The green LED will flash rapidly whenever the N.C. contact is open
and the relay is inactive.
Important Notes:
1. Always disconnect power before servicing the keypad.
2. The keypad must be properly grounded. Use a minimum 22AWG (18AWG is best) wire to
ground the circuit board’s earth terminal. Failure to do so may damage the keypad.
3. All wiring and programming should be done by a professional installer to reduce the risk of
improper installation.
4. Operating instructions are located on page 12 of this manual. Be sure to store this manual
in a safe place for future reference.
Wiring Diagram:
Earth ground terminal: Connect a continuous wire from the Earth Ground terminal to a grounding point to avoid
damage from static discharge. If using an AC adapter for power input, do not connect the AC adapter output to
Earth Ground.

IF USING THE SK-3523-SDQ WITH A MECHANICALLY OPERATED DOOR OR
GATE, MOUNT THE KEYPAD AT LEAST 10 FEET FROM THE DOOR OR GATE TO
PREVENT USERS FROM BEING CRUSHED OR PINNED. FAILURE TO DO SO MAY
RESULT IN SERIOUS INJURY OR DEATH.
