Connection of two detector zones for individual fire and fault alarm
The application provides the separate transmission of a fault alarm (e.g. battery low message)
and an additional fire alarm message. The fault message is non-latching and is resetted
automatically after the cause of the fault alarm is not present anymore.
Reset
The IQ8Wireless transponder is reset to the functional, normal status when the voltage of the
detector zone "Fire" drops below 5 V for at least 60 ms (e.g. by switching the fire zone on/off).
The detector zone can also be reset via an external reset button (refer to ) or a relay contact.
In this case a voltage of 9 V DC to 30 V DC must be switched for at least 1 second at the input
(input +/-) of the IQ8Wireless transponder.
