Mircom QIF-2011 Installation Instructions Manual

QIF-2011 Audio Signal Interface Module
Installation Instructions
The QIF-2011 allows external audio signals to be sent over the paging channel of the
TM
FleX-Net . This configuration will not interfere with the fire alarm/MNS audio system, even in
the case of complete power failure of the QIF-2011.
Up to four different external signals can be connected to the QIF-2011, each with an individual
TM
level adjustment. Signal 1 has the highest priority and signal 4 the lowest. FleX-Net paging
will have absolute priority over all external signals. In addition, jumpers can be set to force the
disconnection of external signals in case of alarm. Signal input 2 (V2:V2) has a built-in
attenuator to allow direct connection of 70VRMS or 25V RMS signal lines to the interface.
Signal input 4 (V4:V4) is for 0dB maximum background music only.
Signal Input (V4:V4) is UL/ULC listed for background music or low level paging signals (0dB or
less). Use of signal inputs 1 to 3 for frequent high-level paging, background music or for
connection of external emergency audio signals is not covered by the UL/ULC listing of this unit
and requires permission from the local fire protection authorities. The jumpers JW7 and JW8 on
the ANC-5000 Audio module must be removed (open) for this application.
The external signals are activated through a dry contact closure. If needed, both the audio and
the control input wiring can be supervised for faults by setting the appropriate jumper. When
supervision is required, 3.9K Ohms end of line resistors must be connected to each control and
audio signal line.
Shielded pairs should be used for all audio signals. The QIF-2011 should be installed next to or
TM
inside the FleX-Net enclosure, using a CH-1063 adapter plate.
