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.

• 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

RELAY OUTPUT #2 -- Example, to shunt an alarm N.C. zone

• 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.
