The following inputs are shared by all interfaces (one per unit):
• Calibration resistor input
• Supervised panel tamper and power fail inputs

PPLICATION
The RDR8S module supports up to eight doors per unit. The I32O16 module
supports 32 inputs, 16 relay outputs, and 16 open collector outputs per unit.
Both RDR8S and I32O16 use standard S300 bus (RS-485) communications
and can interface with the following controllers:
• CK722
• CK721-A version 3.0 and higher
The RDR8S provides the ability to configure supervised 4-state inputs and
unsupervised 2-state inputs. Any points not used for the door can be configured
as general purpose input/output (I/O) points, possibly eliminating the need to
purchase additional I/O modules for certain installations. The RDR8S provides
power for the card reader hardware. It does not provide power for door locking
hardware.
The I32O16 provides the ability to configure supervised 4-state inputs,
unsupervised 2-state inputs, and relay outputs. Additionally, 2 open collector
outputs per terminal are available.
