1.3.7 Input connection- failure notification (INPUT)
On screw INPUT is possible leads voltage 5-24V for activation failure
calling as you can see on picture 7.
Picture 7: Input connection for failure calling
Is possible to programm if input should be activated by connection or
disconnection of voltage on this screw. As next parameter you programm the
lenght of this voltage change before failure calling is activated.
INPUT is possible connecting up to 100m and is possible conecting
moore butons „switch on“ paralel or „switch off“ buttons serial. Control of type
buttons use is possible programming by parameter 6# 1 or 0. System of push
button is wired in current loop and by jumper is select from is loop powered.
Attention
- INPUT is galvanic connect with source power of current
loop and isolated from line by optocoupler. In case powered current loop from
telephone line is button galvanic connect with telephone line.
