The relay is a potential-free change-over contact
assigned permanently as a common trouble relay and
is activated when the fire alarm control panel is in the
normal mode.
If the control panel detects at least one trouble
incident, relay activation will be interrupted and the
relay will change its control status.
This application also permits transmission of a trouble
signal via the potential-free relay contact when the
control panel is in CPU failure mode or in the event of
mains and battery failure.

Monitored inputs IN1 and IN2 allow you to monitor two
external devices, such as an external power supply for
feeding the control panel components.
For each input, Customer Data Editor 8000C may be
used for entering specific additional text of 25
characters in length that will be shown on the plaintext
display and protocol printer in the event of an incident.
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.
