The PVA-15CST is a call station for the PAVIRO system. As standard, the call station has a gooseneck microphone with pop shield and permanent monitoring, a total of 20 buttons, an illuminated LC display, and an integrated loudspeaker. The call station can be modified to suit the user's requirements by connecting up to five PVA-20CSE call station extensions, each with 20 customizable selection buttons. Other properties:

• Five menu/function keys (pre-programmed) - one green or one yellow indicator light per button
• 15 selection buttons (customizable) - two indicator lights (green/red) per button
• Numeric zone selection (can be activated during IRISNet configuration)
• Label with transparent covering - the label can be changed at any time
• Can be used as a standing or desk/rack flushmounted device
• Internal monitoring with error logging - complies with all relevant national and international standards
• Easy configuration - use of the Configuration Wizard or IRIS-Net software

Compact unit with mounting clamp, non-addressable interface between Praesideo network and a multi-mode glass fiber interconnection to a second fiber interface, powered from Praesideo network.

A Plena end-of-line board is a PCB designed to detect the 20 kHz pilot tone generated by a supervised public address or voice alarm system. It activates a voltage free switch in the presence of a 20 kHz signal (pilot tone) above 5 V, as well as an LED for easy visual confirmation of operation.

Functions

Plena end-of-line boards monitor the presence of a pilot tone on a loudspeaker line. The board connects at the end of a loudspeaker line and detects the 20 kHz pilot tone signal. This signal is always present on the line: when back ground music (BGM) is playing, when a call is in progress, and when no signal is present. The 20 kHz tone is inaudible and at a very low level (-20dB). When the pilot tone signal is present, an LED lights up, and a contact on the board is closed. When the pilot tone fails, the contact opens, and the LED goes off. If mounted at the end of the loudspeaker line, this applies to the integrity of the whole line. Presence of the pilot tone signal does not depend on the number of loudspeakers on the line, the load on the line, or the line capacitance. The contact can be connected to a PA system, such as the Bosch Voice Alarm System, to detect and report faults on a loudspeaker line.

Several EOL boards can be daisy-chained to a single fault input. This allows a loudspeaker line with several branches to be monitored.

Since the background music also includes a 20 kHz pilot tone signal, there is no need to interrupt background music.

The PLM-8CS PLENA matrix 8 Zone Call Station is an accessory of the PLM-8M8 PLENA matrix 8 channel DSP Matrix Mixer, and like any good accessory it has a complementary aesthetic design, but behind the good looks and sleek design, there is a product of substance and usability. With one touch, the call station can call either a single zone, or a user defined group of zones. Installation couldn't be easier; Powered over standard CAT 5 from the PLM-8M8, the unit's communication is via RS485, this means that multiple call stations can be daisy-chained together reducing cable runs and installation time.

Functions

Controls and indicators

There are 8 capacitive touch areas on the surface to select zones before a call, and the LED lights are white. The PTT button is a mechanical interface, to give the user tactile feedback that the PTT has been activated. In addition to this feedback there is a LED strip above the PTT button to give the indications when the zone is busy "red" , to wait while a preamble chime is being played "yellow" , and to indicate the microphone is open and active "green". LEDs illuminate in the microphone stem and the PTT LED strip giving the user confidence that the microphone is open and active.

Labeling

Labeling the unit couldn't be easier. Simply use the PC GUI software to print of the labels. This will also include white text on black background, so the aesthetics of the unit are kept.

Unit ID and Priorities

? Priorities are made in the software of the PLM-8M8 8-channel DSP Matrix Mixer, and each call station has its unique ID, this is set via DIP switches in the base of the call station.
