User manual AUSTRALIAN MONITOR PAGENET 88

[. . . ] Any program source operating in to a selected zone will be muted by any paging mic when an announcement is broadcast in to that zone. An added feature of the PageNet system is that zones can easily be removed from the paging function via front panel buttons on the matrix. For example, if a meeting room in a hotel is not to be disturbed, then that zone can be easily taken out of the paging chain. Likewise at the end of the meeting, the room can again be added to the paging function. [. . . ] Rocking the switch in to the `Up' position turns on the AC power. When the switch is in the `On' position, a blue LED located above the switch will illuminate. If the PageNet matrix is connected to a 12-24 volt DC supply, this switch will not effect the operation of the system from the DC supply. If both AC and DC are connected, then the PageNet will continue to operate normally when this switch is turned `Off'. The DC supply needs to be disconnected from the rear panel to completely `turn off' the PageNet matrix. Rear Panel Features AC Power Inlet The 3 pin IEC power inlet is located on the bottom left of the rear panel and accepts a standard mains power lead fitted with an IEC connector. Before plugging in a power lead, please check the rear panel to ensure that the voltage label shows the correct AC operating voltage for your part of the world. The inlet is equipped with an in-built AC fuse holder fitted with a 1 Amp slow blow fuse plus a spare fuse. Please ensure that the mains power cord is disconnected before attempting to check or replace this fuse. Power consumption is 25 VA (max). Terminal Strip The terminal block below the mains power inlet provides a number of functions. A `Phoenix' connector block (supplied) can be unplugged for easy cable connection. This terminal block carries the following features: 12VDC: The PageNet matrix will operate from 12-24VDC. Connecting a line level source to the `SUM and `COM' (see below) allows a 5th input to be active to all zones. This input mixes with all other inputs and is transmitted to every zone irrespective of the status of `Page Enable' section. The 5th or SUM input can become a priority input by simply making and holding a contact closure (COM and EMERGENCY). When an EMERGENCY contact closure is held, the SUM signal will have overall priority and be broadcast into every zone (including de-selected zones) while the contact closure is held. Such an input may be used for an external evacuation signal, or for special pre-recorded announcements. EMERGENCY: When used in conjunction with COM as a contact closure, this trigger will mute all program sources while the closure is held. It may be used in conjunction with the `SUM' input (see above) or simply used as an overall mute switch (possibly to shutdown the unit in the event of a separate evacuation system being activated) ALERT: The Alert terminal is an activation point (when used with COM) for the in-built Alert tone generator. EVAC: The Evac terminal is an activation point (when used with COM) for the in-built Evacuation tone generator. The Evac tone will mute all program sources when it is active. 15 Pin Connectors Eight 15 pin `D Sub' connectors are provided as a logic input from each of the 8 zone microphones. Microphones 1 and 2 have priority over Mic's 3-8 and need to be wired back to the matrix. Microphones 3-8 however can either be cabled back to the matrix or `daisy-chained' (15 pin input and output connectors are provided on each mic). [. . . ] Service Information Equipment should be serviced by qualified service personnel when: A. The equipment does not appear to operate normally, or exhibits a marked change in performance E. The equipment has been dropped, or the enclosure damaged. Engineered by Audio Telex Communications Pty Ltd, Sydney, Australia A. B.
