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 Fire Alarm Control Panel 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 for
feeding the control panel components.
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 Fire Alarm Control Panel.
For each input, Programming software may be used for
entering specific additional text of 25 characters in length
that will be shown on the alphanumeric display and protocol
printer in the event of an incident.
