Instructions

An inter-lock system requires at least two code locks. In this example, two DK-9523 devices
are connected. Output 13 is connected to output 14 on the other device. Both devices must be
connected to the same GND (-) via output 15. This prevents the second door from opening when
therstdoorisopened.Ifdesired,thegreenLEDcanbeconnectedtoindicatethedoorstatus.
• A keypad is placed next to each door on the outside of the room.
• A door opener is placed next to each door inside the room.
• The door sensors are connected to the keypad next to each door.

automatic devices).
• Refer to the instructions for examples 1 and 2.
14. Useful tips for auxiliary features
a) Tamper monitor (NC)
The contact between pin 1 and pin 2 is normally closed (NC). This contact is broken if the device
is forced open. The contacts can be integrated into a 24-hour surveillance system for compre-
hensive monitoring. The connections can be left unconnected.
