supply at an earlier time can result in severe damage or injuries, depending on the condi-
tion of the system and the environment.
In order to provide a clearer overview, the components of the EMC protection circuits of the inputs
and outputs that are provided on the control board are not shown in the connection diagrams.

Power supply

The Purging unit can be powered by a separate power supply unit, or by the power supply device of
the aspirating smoke detector.
In order to avoid undefined potential situations, the inputs and outputs for the control lines between
the Purging unit and the evaluation unit of the aspirating smoke detector are potential-free within
the unit.
If several Purging units, each with its own independent power supply device, are operated with a
common timer for synchronising the time or with a common push-button „Manual activation" or
something similar, the supply voltage minus terminals of the Purging units (terminal 2) must be
connected to each other.

9.4 Connection of and interaction between Purging unit, aspirating smoke detector
and fire detection control panel
Perform the connection in accordance with Figure 12 or 13 below. The connections that are needed
for the respective function are represented by solid lines, the optional connections are represented
by dashed lines.
All contacts in Figures 12 and 13 are shown in the de-energised condition of the devices, which
means
– the fault contacts of the F-BO-AFE70 and of the ASD are in the „fault" condition.
– the alarm contact of the ASD is in the „no alarm" condition.
It is recommended that the alarm output and the fault output of the aspirating smoke detector
should be evaluated separately and connected separately to the fire detection control panel.
The alarm contact of the aspirating smoke detector is connected to the fire detection control panel
like a standard fire detector, by means of a monitored line (e.g., via a conventional line or a loop
input module). The fault contact of the aspirating smoke detector is also connected like a standard
fire detector, by means of a monitored line (e.g., via a conventional line or a loop input module), to
the second input of the fire detection control panel. For the required resistance values of the resist-
