Connection to input/output module

Aspirating smoke detectors FDA241 and FDA221 can be connected to a fire
control panel via an input/output module.
For fire control panels FC20xx and FC72x, the aspirating smoke detector should be
connected via the communication transponder FDCC221S, see chapter
'Connecting to the detector line with the FDCC221S [➙ 71]'.
NOTICE
Incorrect configuration of the fire control panel
Signals from the input/output module are not evaluated correctly
● After connecting the input/output module, check the configuration of your fire
control panel.
● Adapt the configuration if necessary.
Only use potential-free contacts to connect the input/output module to the
interface card [➙ 29] of the aspirating smoke detector.
The 'Smoke 4...20 mA' analog output must not be used to connect the
input/output module.
An output on the input/output module must be connected to the configurable 'GPI'
input of the aspirating smoke detector so that it is possible to reset an alarm or
the status of the aspirating smoke detector from the fire control panel.
Please be aware that the configuration of the aspirating smoke detector must be
adapted using the 'FXS2051 ASD Configuration Tool' software in this case. See
also document A6V10332759, chapter ''Other settings' menu', section 'Reset
input configuration options'.
Different connection variants are possible. Two variants are shown as examples
below.
The selection of a suitable input/output module is dependent on the number of
inputs and outputs required.
