SaS-Relay
exteral device
FAULT
Contact : change-over (EMI protected)
Breaking capacity : 30 V DC / 1A
Function : Common trouble (SaS-relay FAULT)
If the control panel detects at least one trouble incident, relay
activation will be interrupted and the relay will change its
control status.
Normally energized mode of the relay contact
The relay is activated when the FACP is in the normal mode.
This application provides a fault message even in the
emergency operation of the panel. In case of a total power
loss, a fault message can be transmitted via the dry relay
contact.

Do not connect relays (AE) of the FACP with alternating voltage. Even in the case of a >dry relay
contact< it is not possible to switch an external AC-voltage.
Inputs IN1 and IN2
GND
e. g. external power supply
12
IN
Monitored inputs IN1 and IN2 allow you to monitor two
external devices, such as an external power supply.
An external contact is required for activating an input and will
be open in the normal mode. This contact is used to switch
input IN1 or IN2 to GND in order to send a trouble message
to the FACP.
For each input, customer data may be used for entering
specific additional text of 25 characters in length that will be
shown on the display and protocol printer in the event of an
incident.
