Connection diagram KleverKey reader KK2150 with security module

This article describes how the KleverKey reader KK2150 incl. security module can be connected to an external control unit or a door opener.

Introduction

The reader must be installed outside the door and connected to the remote security module (RIM) via a 4-wire cable. The security module has a potential-free relay output (BO0) to which various electrical loads such as a motor, door opener or a digital input of a control unit can be connected.

A DC power supply must be used to power the safety module and the reader: 12-24VDC, min. 5 W (see power supply KK2150).

Important:

• If the reader is installed to secure an outside door, we strongly recommend using a security module to increase overall security.
• The safety module has a tamper contact. As long as the cover of the safety module is not closed, the closing contact does not switch.
• On the KK2150 reader, all DIP switches must be set to OFF. Otherwise, the reader remains in the bootloader and flashes in different colours.
• Only one KleverKey Reader KK2150 can be connected to a security module.
• The KleverKey Gateway should be placed near the KleverKey Reader KK2150, as the Gateway transmits authorizations to the Reader via radio.
• The maximum achievable degree of protection IP54 depends on the sealing against the wall. Cable entries and fixing holes must be sealed with a sealant if necessary. Suitable sealants (e.g. silicone) must be selected according to the ambient conditions.

Control unit with input type (potential-free) closing contact

If the control unit has an input of the type "closing contact" or similar, the following wiring diagram could be considered. This input type is normally used for direct connection of a button or switch to manually close a door by pressing the button or switch.

Note: The relay of the safety module can switch max. 30VDC, max. 2.0A

Control unit with input type "digital input" or electrical load (motor)

If the control unit has a "digital input" input type, the following wiring diagram could be considered. This input type is normally used to connect another electronic device to the control unit.

Important: Make sure that the voltage levels of the safety module and the control unit match. The safety module can be operated with 12-24VDC at typ. 1W (max. 5W).
