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.

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.

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

The RM-325 is a 2-channel intercom user station for the RTS-TW Intercom System. It is designed for use with a headset, and it can be placed on a desktop, or rackmounted with optional rackmount hardware.

The SS-1002 and SS-2002 Intercom Speaker Stations may be used with a headset, a built-in speaker and panel microphone, or an optional gooseneck microphone. As an alternative to a headset, a telephone-style handset may also be used. The SS-1002 is a single-channel station; the SS-2002 provides switch selectable access to either of two (2) intercom channels. Both the SS-1002 and SS-2002 come in four (4) versions to suit a variety of applications. The "S" and "P" boxes are portable versions. It has a carrying handle and dual "loop-through" intercom connectors which permit stations to be quickly interconnected using prefabricated cables. The "RM" box is a stationary version. It also has dual "loop-through" connectors for quick interconnection, but the case is designed for desktop or console-mount applications. The "U" box is designed for permanent, in-the-wall mounting. It uses push type wire terminals for connection to the intercom system. In addition to the standard SS-1002 / SS-2002 units, there is a two (2) channel "RM" version. The rack-mountable ("RM") version is suitable for desktop use, or can be rackmounted using the optional RM-14 rackmount kit.
