Inputs
5.7.5.1 Line monitoring
32
The access manager has 4 inputs IN1 to IN4.
Function of the inputs
The inputs are used for the inquiry of sensors such as door-opener key, door handle
contact, door frame contact, bolt contact, vandal contact, passage control (e.g., turn-
stile, light barrier), etc.
The function of the individual inputs depends on the selected door template.
Principle
The inputs (IN1-IN4) are activated by means of a potential-free contact (switch or re-
lay contact). An open input is recognized as "high" due to the internal pull-up resis-
tor.
The inputs can be designed as follows:
•
Without line monitoring
•
With line monitoring (if supported and activated by the terminal software)
Line monitoring allows the terminal software to detect the states short circuit and in-
terruption, in addition to the states active (input closed) and not active (input open)
and report them to the higher-level system.
The current states of the inputs are indicated by light emitting diodes (see chapter
Light emitting diodes [} 4.10]).
