Sensors of the "Dry contact" type

Attention! There are 12 V, up to 200 mA on the input / output lines of the device (IO1-IO4) in the "output"
mode, . If used improperly, the connected equipment may fail.
The number of connected dry contact sensors is limited by free IO lines of the device and the total current
consumption of the sensors, if they require additional power.
If the sensor needs extra +12 V power, you need to use one of the input / output lines in the "output" mode. Thus, it
is possible to control the power of the sensor additionally using a logical level on the line. This can be useful, for
example, in the case of sensors whose alarm is reset by removing power.
If the factory cable length is not enough, it can be increased by using If the factory cable length is not enough, it can be increased by using
each other each other sequentially sequentially sequentially sequentially sequentially sequentially sequentially sequentially
The maximum permissible loop length is 100 meters. The maximum permissible loop length is 100 meters.
The corresponding IO line to which the signal wire from the sensor is connected must be switched to the
"input" mode in the device settings.

Two wire sensors

Sensors and other signal sources which do not require additional power or they are powered from other power
sources and it is isolated from the signal line, connected to the IO and GND terminals of the device. The polarity of
the connection is important unless otherwise directly indicated in the documentation for the sensor.
Such type of sensors include:
• Supply voltage sensor
• NetPing Supply Voltage Sensor 995S2

• Door sensor metal
• Air Flow Sensor (model AMC520)
