Note:
• Connect a 1N4004 diode as close as possible to and in parallel with the DC-
powered electromagnetic or electric lock. This absorbs possible electromagnetic
interference to prevent operation of the lock from damaging the keypad. A 1N4004
is not required for AC-powered locks.
• Connect the ground (-) terminal of the keypad to earth to prevent electrostatic
discharge from damaging the keypad.
• The connection of relay output #1 disable to output #3 as shown above is optional.
When so wired, output #3 is the inhibit control. To use, program output #3 for shunt
on/off operation. When output #3 is ON, relay output #1 will not work. For example,
this can be used to prevent users from entering the protected premises during the
evening or weekend. See programming option 61.
• As wired, the green LED lights while relay output #1 is activated to activate the
lock.
• As wired, the red LED lights to show that relay output #1 is disabled by the
activation of output #3.
• Tape all unused wires to prevent short circuits.
WARNING:
• If the inhibit control is used, all personnel must exit the protected premises before
output #3 is activated. Otherwise, personnel in the protected premises will not be
able to exit until output #3 is turned OFF.
• The user code for output #3 in this case should be given only to personnel
authorized to enter the premises any time. It should not be given to other users.

The Key Active Output will switch to ground (-
+12V
) for 10 seconds whenever a key is touched.
Use to turn ON an LED and/or a small buzzer
N.O. relay
to notify a guard, or to energize a relay to
contact
switch ON lights or CCTV camera.
Only one connection option is recommended.
Isolation
Make sure the current does not exceed the
relay
maximum rating of 100mA.
An external power supply and isolation relay
are necessary to drive high power devices
such as lights or CCTV cameras.
Use Normally Open (N.O.) output
contact to shunt a Normally Closed
(N.C.) protection zone of an alarm
To protection zone of an

system.
Set relay output #2 to Start / Stop mode
