10.2.8 TB-8/TB-9 - General Purpose Input Connections
General-purpose inputs may be used in conjunction with the programmable input/
output feature of the Doors access control software. The normal state of these inputs
can be either a closed circuit that will be opened when an input is generated or an open
circuit that will be closed when an input is generated. No voltage is applied at these
inputs; the circuits are either opened or closed to indicate an input event. Refer to the
General Purpose Input section on page 34 for more information on general-purpose
inputs and input devices.
For examples of typical general purpose input connections, refer to Table 31 and
Figure 10-13 on page 86 and make the following connections.

Configuration
TB-8/TB-9 Description
TB-8, Pin 1 door status switch input - normally closed
TB-8, Pin 2 Common/Ground
TB-8, Pin 3 RTE input - normally open
TB-8, Pin 4 GPI 3 input a
/Aux RTE-B
b
input - normally open
a. General Purpose inputs can accept either a normally closed or
normally open signal. The type of signal depends upon the type of
input device. The Doors software is then programmed to accept
that type of input.
b. The Auxiliary RTE input feature is not available in 16-bit Doors
software applications.
