67.1.5 Input Circuit Wiring
Typically, these inputs are used to monitor door position, request to exit, or alarm contacts. Input circuits can
be configured as unsupervised or supervised. When unsupervised, reporting consists of only the open or
closed states.
When configured as supervised, the input circuit will report not only open and closed, but also open circuit,
shorted, grounded*, and foreign voltage*. A supervised input circuit requires two resistors be added to the
circuit to facilitate proper reporting. The standard supervised circuit requires 1K Ohm, 1% resistors and
should be located as close to the sensor as possible. Custom end of line (EOL) resistances may be configured
via the host software.
* Grounded and foreign voltage states are not a requirement of UL 294 and therefore not verified by UL.
