IQ8Wireless transponder for wall mounting
34 FB 798941 / 10.06
10.3 Operation on a conventional detector zone
The IQ8Wireless transponder can be connected to the conventional detector zone input of a
fire alarm system via the relays. All IQ8Wireless devices form a common detector zone on this
IQ8Wireless transponder. You cannot split these into several, different detector zones. The
detector zone input is connected with resistor (R1) to the inversely operated >common fault<
relay (Common fault) which is activated in quiescent mode. In case of an alarm the alarm
resistor (R2) is switched parallel to R1 and the detector zone is triggered via the
>common fire alarm< relay (Common fire).
Reset
The IQ8Wireless transponder is reset to the functional, normal status when the voltage of the
detector zone drops below 5V for at least 60ms (e.g. by switching the respective detector zone
e.g. no. 1 on/off). The detector zone can also be reset via an external reset button (refer to c)
or a relay contact. In this case a voltage of 9 to 30 V DC must be switched for at least
1 second at the input (input +/-) of the IQ8Wireless transponder.

Connection data
• External power supply 9 V DC to 30 V DC
• Detector zone voltage 9 V DC to 30 V DC
• R1 quiescent resistor (e.g. 10KΩ for conventional detector zones System 8000/IQ8Control)
• R2 alarm resistor (e.g. 1KΩ for conventional detector zones System 8000/IQ8Control)
• Jumpers J1 and J2 inserted (supplied with package)
• Reset time = 0.2 to 3 seconds
Depending on the detector zone input, with this connection a fault in a single
wireless device can lead to a fault in the entire detector zone and affect the
detector function. In this case the fault message can be moved to a separate
detector zone input, so that devices that are not defective remain functional.
