General functions
FAI logic:
The FAI connections of all detectors are connected to one another. A connection to the control
panel is not required. The LED flashes on the detector that triggers first, the LED light on the
subsequently triggered detectors is static (see 9.4.1).
Contacts:
Alarm
Contact open in the event of an alarm
Fault
Contact open in the event of a fault
Tamper
Contact open in the event of tamper
Backtamper and tamper are both switched to the tamper output.
To comply with VdS and EN 50131-2-4, connect this output to a tamper detector group at the control panel.
Function of inputs:
(Pull-up resistors in the detector)

Fault Tamper Alarm
If the control panel has no fault input, the "Alarm" and "Fault" outputs can be connected
in series.
