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 line and short circuit. To make these
possible, resistors must be properly connected to the end of lines of the input (Fig. 1). When
an open line or a short circuit occurs on one of the input lines, a fault message is transmitted
to the control panel. The input must be potential-free.
Normal operation (output lines monitored)
-
Be used for controlling (e.g. operating a horn/strobe).
-
The module switches the externally supplied 24 VDC voltage in active status on the
output.
-
In inactive status the output line is monitored for open line and short circuit (Fig. 3).
-
The jumper on the input/output module must be plugged onto J2 (Fig. 2)

Configuration
The following configurations are possible through controller or configuration tool:
After activating the output remains:
l
Steady output
‒
Pulse output: How long the contact remains active can be configured by controller or
‒
configuration tools (pulse duration).
Failsafe behavior when the FD18-BUS detector line is current-free or in degraded mode.
l
The error behavior defines the position of the output in case of an error:
Off: Output remains in the same position as before the error
‒
Activation: Output is activated in case of an error
‒
Deactivation: Output is deactivated in case of an error
‒
The controller does not monitor external equipment status (activated/inactivated).
Inverted operation (output lines not monitored)
-
Be used for controlling (e.g. closing a door).
-
The module switches the externally supplied 24 V DC voltage in active status on the
output.
-
In normal status there is no monitoring for open line and short circuit.
-
The jumper on the input/output module must be plugged onto J2 (Fig. 4).
