QIF-2011 audio signal interface installation manual
The QIF-2011 allows external audio signals to be sent over the paging channel of the
QX-5000.
Up to four different external signals can be connected to the QIF-2011, each with an
individual level adjustment. Signal 1 has highest priority, signal 4 the lowest. Jumpers
allow setting the priority of the signals over QX-5000 native paging or alarm signals.
Signal inputs 3 and 4 have built-in attenuators to allow direct connection of 70VRMS or
25VRMS signal lines to the interface.
The external signals are activated through a dry contact closure. If needed, both the audio
and the control inputs 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 lines.
Outputs are provided to control which zones are selected for paging. Each signal can
control a specific number of zones as programmed using the QX-5000 audio configurator
(this requires a QIF-2000 input extender to be installed in the QX-5000). For simpler
systems, a common output is provided for direct interface to one of the QIF-5000 opto-
coupled inputs.
A dry contact is provided for strobe controls. It will close if either external signals or
QIF-5000 paging are active.
Shielded pairs should be used for all audio signals. The interface should be installed next
to or inside the QX-5000 enclosure.

  • Page 6 In that kind of system, supervision is not used for the signal lines: The 70V line is supervised by the existing panel and the background music is not an alarm feature. The jumpers will be set as follow on the QIF-2011: Remove Z1,Z2,Z3,Z4 jumper pairs...
  • Page 7: Material Required

    Material required: In addition to the basic material required for QX-5000 operation, a QIF-2000 must be used to provide zone selection specific to either external paging or background music. A 3.9K End of line resistor must be installed at the fire alarm panel to provide supervision for the command line for the external emergency paging signal.

  • Page 12 If only all-call is required for all external signals, connection to a QIF-2000 is not necessary and the QIF-2011 can be connected to opto-input #3 or 4 on the QIF-5000B if those are free. The configuration would be modified as follow:...
  • Page 13 ANC-5000 must be done as per figure 8. Priority jumpers must be removed and jumper JW27 on the QIF-2011 must be set as shown. Also, jumpers JW7 and JW8 must be installed on the ANC-5000. The basic scheme shown is suitable for all call operation of the FleXNet.
