User manual AUSTRALIAN MONITOR PAGENET 88

[. . . ] PageNet 88 Zone Paging System Operating Manual PageNet 88, Zone Paging System Product Description The PageNet is an 8 zone matrix system designed to accept up to 8 zone paging microphones, 4 program sources and 1 priority input. The heart of the system is the PageNet 88 matrix which allows any of the 4 program inputs to be assigned to any of the 8 output zones. Up to 8 zone paging mics (PageNet 88M only) can be used with the system, allowing any combination of the 8 zones to be paged from any of 8 different locations. The PageNet 88M is an attractive, compact desk mic with `Zone Select', `Zone Page', `All Page, and `Clear' buttons, The mic base also includes status LED's for each zone and a `System Busy' LED. [. . . ] 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. Simply connect DC power source to the +/­ terminals. SUM: This can be seen as a 5th auxiliary input. 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. A Trim control for the SUM is provided internally. 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. The Alert tone will mute all program sources when it is active. [. . . ] Do not operate equipment on a surface or in an environment which may impede the normal flow of air around the unit, such as a bed, rug, weathersheet, carpet, or completely enclosed rack. If the unit is used in an extremely dusty or smoky environment, the unit should be periodically "blown free" of foreign matter. Removing the cover will expose you to potentially dangerous voltages. There are no user serviceable parts inside. [. . . ]
