“Status” inputs and “Alarm” inputs
“Alarm“ inputs trigger an alarm as soon as the input is activated. “Status“ inputs trigger a
monitoring status change as soon as they are activated.
Line monitoring and circuitry
The input lines are monitored for open line or open/short line. To make these possible,
resistors must be properly connected to the end of lines of the input (Fig.6). When an
open line or a short line occurs on one of the input lines, a trouble message is
transmitted to the control panel.
The input must be potential-free.
Structure
The module consists of the module carrier, the printed circuit board, the cover and the
protection cover. The printed circuit board includes the LEDs. The LEDs indicate the
status of the inputs. The cover of the printed circuit board is transparent, so that the state
of the LEDs is visible even when the housing is closed.
To protect the modules from environmental influences, there are additional options for
the housing.
