System limits and restrictions - Planning

A pilot tone amplifier is required to enable these features:

• Supervision of switched-off speaker lines (priority only)
• EOL3 line structure detection features (search EOL3, measure impedance, measure 1 kHz VA)
• Multiple speaker lines on an amplifier in bulk zone configuration

• Within a tree topology, you are permitted to have up to 15 ↑ hops from the central network distribution hub to a branch.
• 1GBit hops: up to 50 on fiber optic and copper
• With a ring topology, a minimum of three and a maximum of 30x PN2005 switches are permitted.
• Only the Ethernet switch PN2005 supports ring topology.

• 'PACE-Bus' limits are for one digital audio matrix.
• Do not connect the 'PACE-Bus' to two digital audio matrices.
• The UART speed must be set to 19200 baud.
• A reboot of the host station is necessary if a station ID is used with a different station type.
• 1x PT2003 can be used together with 1x I/O expander 1x PT1001 or 1x PT1002 or 1x PT2006 (cannot be used together with PT2009)
• Up to 1x PT2009 with connected PTO2006 used as emergency call station or
• Up to 8x PT2006 (with 4 different presets) can be used on the 'PACE-Bus' or
• Up to 3x I/O expander, e.g.: 3x PCIO200x, or 3x PCO200x or
• Up to 2x I/O expander together with 1x PT1001 or 1x PT1002 or
• Up to 4x 'PACE-Bus' members can be used on the 'PACE-Bus':

• 4 standard call stations e.g.:4x PT2009 with connected PTO2006, all together with maximum 72 buttons
• 1x PT2009 + 1x PCO200x + 1x PT1001 + 1x PT2006
• Cerberus PACE: 1x PT2003 can be used on the 'PACE-Bus' together with
• 1x I/O expander or
• 1x PT1001 or
• 1x PT1002 or
• 1x PT2006
• cannot be used together with PT2009
• PT2003 has the same priority as a virtual keypad.
• If a PT2003 is used, the virtual keypad shall not be used for other purposes than the PT2003 functionality.
• Alternatively: take care about the priority of the announcements and take care of triggering SD card files in selected zones by an appropriate configuration.
• PT2003 only supports the following button functions:
• Zone Select
• Select All
• Select None
• Play from SD-card
• Stop Sound
• PT2003: loudspeaker not working (up to FW1.3.3.4)
• PT2003: 'Select All' only works if at least one zone key is defined
• PT2009: loudspeaker not working (up to FW1.3.3.4)
• PT2009: 'Select All' only works if at least one zone key is defined

• Only one local analog audio input is available in the 'mixer panel'.

• Program channels shall not be used for evacuation purposes.

• It is not allowed to set all channels of one amplifier to 'Priority Only'. If so, the connected amplifier will not be supervised as long as no assigned priority channel is active.
• For PC2003: the maximum speaker line load for the internal pilot tone amplifier (sum of all 'Priority Only' channels) is 700 W.

• No more than one '*.wav' file can be played simultaneously per SD card and per station.
• The channel number of the SD card is restricted to analog audio input 1 (IN1).
• The data block size within a '*.wav' file is restricted to a maximum of 512 bytes.
• In bulk systems, a short sound can be heard in the zones connected to the same amplifier when one of the zones is activated. To avoid this, take one of the following options:
• Add a dead time of 100 ms to the playback.
• Add a time of 200 ms with the level of Zero to the beginning of every '*.wav' - file
• Add a delay of 100 ms at the start of the SD card
• In a digital audio matrix with an integrated SD card, the connected call stations PT2008, PT2003 or PT2009 and the SD card announcement have the same signal priority.

• The record buffer has a max recording time of 60 seconds.

• The AVC function can only be used with the PC1001, PC1002, PC2001, PC2003 and PC2005.
• The 'Automated volume control module' PCA2008 can only be connected to the analog audio input 4 (IN4).

• Max. 16 EOL3 per amplifier
• Max. 16 EOL3 per speaker line
• Max. 64 EOL3 per digital audio matrix
• EOL3 is supported by PC1001, PC1002, PC2001, PC2002 and PC2003

• Max. number of loop isolators PCA2005 per amplifier: 80
• 150 W: 80
• 200 W: 80
• 250 W: 80
• 300 W: 80
• 500 W: 80
• Max. number of loop isolators PCA2005 per digital audio matrix PC1001, PC1002 and PC2003: 320
• Max. 80 loop isolators PCA2005 per speaker loop
• Max. 2 speaker loops in one speaker zone per amplifier
• Maximum 200 W in one speaker loop at 100 V continuous sinus signal
• Max audio payload with 80 loop isolators (at 100 V continuous sinus signal):
• 150 W amplifier: 110 W
• 200 W amplifier: 160 W
• 250 W amplifier: 210 W with 2 speaker loops
• 300 W amplifier: 260 W with 2 speaker loops
• 500 W amplifier: 360 W with 2 speaker loops
• Connect to a digital audio matrix either only EOL3 or only loop isolators. A combination is not allowed.
• PV2002 is not recommended to be used with loop isolators.
• Minimum ↑ tapping* of speaker connected to loop isolator: 0.75 W
• Maximum tapping* of speaker connected to loop isolator: 12 W
• If loud background music is to be played in speaker loops, a low pass filter with 14 kHz 4^th order is required.

* Tapping: 100 V speakers have a transformer upstream of the chassis. The transformer has several taps on the primary side, which is where the 100 V speaker line is connected. These taps determine how much power is drawn by the speaker. With a 100 V signal, ceiling speakers typically taps to draw a power of 6 W, 3 W, 1.5 W, or 0.75 W. Halving the electrical power leads to a 3 dB reduction in the analog audio output signal.

• Working in combination with local generated test signals on input/output is not supported.

• The 'Test & Quit key' input enables all outputs on the digital audio matrix (firmware version < 1.3.B5 only).
• The 'Remote Logic Input' function is restricted to the first 32 logic control inputs.
• The 'Local Logic Input' function is restricted to the first 32 logic control inputs.
• Outputs for logic operations are restricted to the first 32 logic control inputs.
• 'GP_OUT:' Only 1…32 can be used via the ↑ API.

• PC1001, PC1002, PC2003: the analog control inputs of the PCIO200x are displayed as analog inputs 1…8.
• When there is a second PCIO200x on the same 'PACE-Bus', the analog control inputs are displayed as analog inputs 9…15.
• PC2001/2002: the analog control inputs of the PT2010 are displayed as analog inputs 9…15.

• Logic control inputs/outputs are restricted to 1…8.
• Analog control inputs 1…15 can be used.
• Analog control input 16 cannot be used.
• Full use of this function cannot be made if a PT2006 is used for the output.

A recursive macro is a macro that includes another macro within it and calls this other macro.

• It is possible to have a recursive macro that calls a button already assigned to a macro.
• Up to five recursive macro calls are supported.
• Maximum 5 remote EmuKey macros on one key are usable. The local usage is restricted only by the maximum memory size.

• Up to 6550 entries can be stored.
• ↑ RSL is restricted to 512 active stations.
• Only the first 24 inputs can be logged when 'logEvents' is active.

• Max. number of stations = 1350
• Max. number of analog audio outputs from stations to amplifiers = 1600
• The cycle time/system latency is permanently set to 1.3 ms.
• The system sampling frequency is 48 kHz.
• Viewing configuration data of protected systems requires a protocol driver that is bound to a local network adapter (no physical connection is required).
• The 'Duplicate Station ID' error can only be resolved by disconnecting one of the components from the network.
• PACE-Design > V1.3.3. Changing a station ID of a station resets it to factory settings to avoid inconsistent configuration settings. This station requires a new configuration.
• '*.wav' files on a SD card will only be played if the logic control inputs have been linked in the SD card dialog.
• If any changes are made in the SD card dialog, the link must be reestablished.
• PACE-Design ≥ V1.3.4: the activation of higher priority SD card files on a channel stops the playing of lower priority files.
• If the higher priority file stops playing, the lower priority file will not be reactivated automatically.
• Station function 'Get SD-Card Directory' does not return all files if number of files on the card exceeds 32 (DSP issue).
• Use the command 'Show Dir' in the 'microSD Card' configuration window to get all files.
• Loading snapshots: a loaded protocol driver bound to a local network adapter is needed in order to view configuration data of protected systems (but no physical link is required).
• System protection: the error messages 'Members Mismatch' (after adding or removing stations) and/or 'Security Mismatch' can be solved manually via the menu 'Extras' > 'System Protection' > 'Members Mismatch'.
