Input
With the input a status can be monitored, the input can be configured by controller or
configuration tools as follows:
l“Status“input or “Alarm“input
lLead monitoring for open line or open line and short circuit
lWhen inputting status, according to different status of contact, can be set as fallows:
– Normal mode: normally open NO input
– Inverted mode: normally closed NC input

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.
Output
External power output (Default)
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)

Fig.3 Connection for normal operation with output line monitored for short circuit and open line
Configuration
The following configurations are possible through controller or configuration tool:
lAfter activating the output remains:
‒Steady output
‒Pulse output: How long the contact remains active can be configured by controller or
configuration tools (pulse duration).
lFailsafe behavior when the FD18-BUS detector line is current-free or in degraded mode.
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).

Fig. 5 Connection diagram for inverted operation, e.g. when used as door retainer.
In inactive status the 24 V DC are permanently applied to the output and may keep a door
open, for example. When the output is switched to active, the output goes into "open" status
(= no 24 V DC voltage) and the door is closed.
Comment:
In this example, the door would also close if the 24 VDC supply were to fail, e.g. due to a line
problem (short circuit, open line).
Configuration
Under inverted mode, the following configurations are possible through controller or
configuration tools :
lAfter activating the output remains:
‒Steady output
‒Pulse output: How long the contact remains active can be configured by controller or
configuration tools (pulse duration).
lFailsafe behavior when the FD18-BUS detector line is current-free or in degraded mode.
The error behavior defines the position of the output through controller or configuration
tools 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).
Dry contact output
Potential-free contact (Output not monitored)
-Be used for controlling (e.g. closing a door).
-Output control is not monitored.
-An externally supplied 24 V DC voltage is not needed.
-The jumper on the input/output module must be plugged onto J1 (Fig. 6).

Configuration
The following configurations are possible by controller or configuration tools :
lThe contact is active, when:
‒Normal mode: normally open NO closes
‒Inverted mode: normally closed NC opens
lAfter activating the output remains:
‒Steady output
‒Pulse output: How long the contact remains active can be configured by controller or
configuration tools (pulse duration).
lFailsafe behavior when the FD18-BUS detector line is current-free or in degraded mode.
The error behavior defines the position of the output through controller or configuration
tools 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).
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 states of
the inputs/outputs. 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, housing FDCH221 is optional.

Preparation
1. Determine type of installation:
– Installation outside a switching cabinet or a control unit:
use FDCH221 housing (Fig. 10) .
– Installation directly in a switching cabinet or a control unit:
mount the module on an even surface (Fig. 9).
Damage by water!
In humid or wet environments always use FDCH221 housing!
Mounting FDCH221 housing
1. Open the housing.
2. Determine the position of the cable entries in the housing
and break them out.
3. Mount the housing on an even surface with two screws
(Fig. 10). Distance between holes: 182.0±1.0mm.
4. Insert the cables and fix the cables in the housing.
5. Insert the seal and fix the lid additionally with four screws
(Fig. 11) (only this way is IP65 protection guaranteed).
The housing lid is transparent. Consider a suitable
installation position to make sure that the LEDs of the
module are visible at any time.
