WARNING
• For safety, ensure that no
one is inside the premises
before starting the door
lock inhibit function.
During inhibit, doors
remain locked.
• 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 #2, as shown above is optional. When so wired, output #2 is the
inhibit control. To use, program output #2 for shunt on/off operation. When output #2 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.
• The green LED lights while relay output #1 is activated to activate the lock.
• The red LED lights to show that relay output #1 is disabled by the activation of output #2.
• Tape all unused wires to prevent short circuits.
WARNING:
• If the inhibit control is used, all personnel must exit the protected premises before output #2 is activated. Otherwise,
personnel in the protected premises will not be able to exit until output #2 is turned OFF.
• The user code for output #2 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
(-) for 10 seconds whenever a key is
touched. Use to turn ON an LED and/or a
small buzzer to notify a guard, or to energize
a relay to switch ON lights or CCTV camera.
Only one connection option is recommended.
Make sure the current sink does not exceed
the maximum rating of 100mA.
An external power supply and isolation relay
are necessary to drive high power devices
such as lights or CCTV cameras.
RELAY OUTPUT #2 -- Example, to shunt an alarm N.C. zone
Use Normally Open (N.O.) output
remove to shunt a Normally Closed
(N.C.) protection zone of an alarm
system.
