Loudspeaker Interface
RK-ZONE8 has 2 groups (A and B) of loudspeaker line terminals, each group can separately connect
to 8 loudspeaker lines. 1A and 1B output the same signal and can't be controlled separately.

Matching terminals are attached in the package, the cable with a cross-section of 0.5mm
to 1.5mm
is recommended.
Contact Input Interface
There are 8 contact inputs which can be supervised as needed. The interfaces can be directly
connected with dry contact outputs of third-party devices. Do not connect other power sources to
these ports.
When the supervision function is disabled, dry contact outputs of the third-party devices can be
directly connected to contact inputs. When supervision function is enabled, two 10k ohm resistors
should be installed on the dry contact outputs of the third-party device, as shown below.
Debug interface is a RS-232 port, which can be used to upgrade the firmware.

is recommended.
Note:
The voltage of contact input is 24 V DC. Only a switch or relay can be connected. Make sure the
signal type of the interfaces matches with the third-party device before installation, and not to
connect to an external power source. If the output of the third-party device has any voltage, use a
relay to convert the signal to dry contact.
