IQ8Wireless transponder for wall mounting
FB 798941 / 10.06 37
10.5 Relay outputs
The transponder provides two relay outputs >common fire alarm< and >common fault<. The
operation of the two relays cannot be changed.
If the transponder is connected to a conventional detector zone, the two relays are connected
and are thus no longer available for the >common fire alarm< or >common fault< switch
functions.

Common fire alarm (Sa-Feuer)
The relay output >Common Fire alarm< is activated when at least one assigned IQ8Wireless
base or IQ8Wireless MCP transmits a alarm or fire alarm to this transponder.
Common fault (Sa-Stör)
The >common fault relay< is always activated in normal mode without fault condition. In this
way, if the power supply fails, this relay can still send a fault alarm via the status change of the
relay.
The relay output >Common fault< is activated when at least one assigned IQ8Wireless base
or IQ8Wireless MCP transmits a fault alarm to this transponder or the transponder itself
detects a fault (e.g. power supply).
The relay activation follows the fault alarm (not latched).
