13. Typical applications

a) Standard wiring for a single code lock

• Connecttheybackdiode(1N4004,includedwiththecodelock)tothedoorlockinseries.

Place the diode as close as possible to the lock. When an inductance is switched off (electro-

magnet in the lock), the energy released is routed through the diode. This prevents damage

to the code lock.

• To prevent an electrostatic charge on the housing and keypad, connect the GND (-) output

to a neutral earthed wire.

• The door LED turns on when the door output is connected. If desired, the LED can be con-

guredtostayswitchedoff.

• Isolate all unused connections to prevent a short circuit.

• Congurethelocktype(“Fail-Safe”or“Fail-Secure”)withprogramcode66.

• The use of a door sensor (input T7) is optional. If no sensor is used, this input must be bridged

toGND.Whenasensorisconnected,thedoorlockcanbeconguredtodothefollowing:

- Automatically disable the lock when the door is closed.

- Trigger an alarm when the door is forced open.

- Sound a warning alarm when the door stays open for a preset duration.
