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.

PREVENT USERS FROM BEING CRUSHED OR PINNED. FAILURE TO DO SO MAY
RESULT IN SERIOUS INJURY OR DEATH.

Installation:
1. Unlock the keylock mounted on the face of the keypad
with one of the included keys.
2. Open the faceplate of the keypad. The hinge will allow
the faceplate to open to a 90°angle.
3. Remove the 1” wiring hole cover from back of keypad.
4. Run wires into the keypad using the 1” wiring hole on
the back of the enclosure.
5. Using the wiring diagram on pg. 4, wire the keypad
according to the specific application.
6. Place the included gasket between the keypad and
mounting surface.
7. If attaching the keypad to a mounting plate such as a
gooseneck stand, use the 4 mounting plate holes
located on the back of the keypad.
These holes are
used to mount the
keypad to a
gooseneck stand.
Wiring –Connecting to a Lock Device and Alarm Arm/Disarm:
1Connect a IN4004 diode (not included) as close as possible and in parallel with an electric strike.
This absorbs possible electromagnetic interference to prevent operation of the strike from
damaging the keypad. Do not connect a diode when using electromagnetic locks.
2 Please consult the alarm control panel’s manual for more information.

1. If an incorrect code is entered 3 times in a row, the keypad will lock down.
2. To use the keypad again wait 55 seconds or disconnect and reconnect the power.
3. To avoid lockout, wait 5 seconds after entering an incorrect code. The keypad will give 3
short beeps. It is now safe to enter another code without being locked out.
Wrong Code Lockout:
Changing Code Length:
1. Disconnect power to the keypad.
2. To make the code length 5 digits, place the PIN3 jumper on pins 1 and 2.
3. To make the code length 4 digits, place the PIN3 jumper on pins 2 and 3 (default).
4. Reconnect power to the keypad.
5. Keypad will beep 22 times, then return to standby mode.
Note: This will delete all previous codes, including the master code. All
other programming will remain.

Restoring Keypad to Factory Default (see pg. 11):
1. Pull the PIN2 jumper from pins 1 and 2 (default).
2. Place the PIN2 jumper on pins 2 and 3. Wait for the keypad to beep 26 times.
3. Pull the jumper and place on pins 1 and 2. The keypad is now ready to be
reprogrammed using the programming instructions on page 10.
Note: This resets the keypad to factory default settings. All user codes
are deleted and the master code is 1234 or 12345 (see above).

Onlooker-Deterrent Coding:
This keypad has built-in onlooker-deterrent coding to help prevent people in the surrounding area from
guessing a user code or master code by following finger patterns.
4-Digit User or Master Code
Enter up to 8 random digits before the user or
master code to help deter any onlookers. If
more than 8 digits are entered before a code,
the keypad will go into lockdown for 55 seconds.
5-Digit User or Master Code
Enter up to 10 random digits before the user or
master code to help deter any onlookers. If
more than 10 digits are entered before a code,
the keypad will go into lockdown for 55 seconds.
