PathFinder Version 4.22 User Guide15.1.4.2 Programming the 4-wire call panel alertThis feature is designed to provide an additional audible indication of an incoming 4-wire callto a panel.To program, select the Panel Config tab and use the navigate keys to choose the panel.Select the Miscellaneous view using the radio buttons. To assign a panel Alert source, rightclick in the window and select from the pop-up source list as shown below.This source can be derived from a Misc. I/O logic card (if fitted) or from an external audiogenerator connected to a matrix input.The panel alert is only audible whilst the logic input generating the 4-wire call is activated.The operation is similar to that of a non-persistent 4-wire tally.15.1.4.3 Logic inputs triggering IFBsThe Logic Input, as an IFB trigger is a useful enhancement to the IFB function. The featureis only available if the matrix is fitted with a 500-10 Misc. I/O card. The reason for targeting aLogic input to an IFB Trigger is to enable panels to be barred from operating IFB circuitswhen the system is operating in a particular mode, for example “On Air”.As an example, if the Logic Input assigned to an IFB trigger is set to, say priority 2, and apanel in the IFB trigger group set to a lower priority, i.e. priority 3. When the Logic input ismade, the panel at priority 3 will no longer break the IFB standing feed and will be barredfrom speaking to the IFB destination.Trilogy Communications LimitedIssue 1Page 89 of 89
