Supported interfaces
Dry contact Inputs
Dry contacts can be connected to the brackets.
For instance door contacts.
The inputs are galvanically connected to the power supply.
•
Unconnected input
has a value of „
0 (Off)
“.
•
Active input
is identified as „
1 (On)
“, Ohmic resistance of the
input against the Common bracket must range between 0
Ω
and 500
Ω
.
Connection parameters:
•
Maximum cable length:
50 metres.
•
Supported sensors:
Any dry contact.
•
Alarm setting for each DI input
• Alarm inactive.
• Alarm state when the contact is activated or deactivated.
• Alarm state when the contact is deactivated.
•
Options for reacting to Alarm state:
Common settings for all inputs.
• No reaction.
• Notify of Alarm by sending e-mail or SMS.
•
Reading period:
800 ms.
•
Range of ID sensors:
Inputs use address ID in the range of 1 to 9.
•
Sensor name:
The sensor can be named independently with up to 12 characters.
•
Sensor disconnection detection:
No, the disconnected sensor returns to the value „
0 (Off)
“.
RJ11 – 1-Wire bus
Digital bus by Dallas Semiconductor, each sensor has a unique ID.
We recommend lines up to a total length of 60 m. There are known
cases of experimentation with bus function up to a distance of
tens to hundreds of metres.
Flawless functioning cannot be guarantee for cables lines than
60 m from one connector on the device. It depends on the make
of the cable, topology of the line and environment where the line is installed.
