How to use 4-State Inputs
A 4-state input can detect the following situations:
•
Active input
•
Inactive input
•
Open circuit (wire cut)
•
Short circuit
To use this input type, you must add two 4.7KOhm resistors (supplied with the module) on
the wires loop detector (or another device). Refer to diagram below.
For all inputs (2- or 4-state), use module’s GND as common. For all outputs, ensure you use
supplied lock suppressors if electromagnetic devices are installed (Electric strike, door
magnet, relay, etc.…)
Each module input can be independently used in 2- or 4-state modes. These modes can
be configured from the embedded web server menu.
To adjust the detection level (if using another resistor value) each input can be calibrated
as well as adjusting the detection range using the configuration options within the
embedded web server.
