Siemens ALCC Desigo Modular Audio Level Conversion Card, data sheet

Fire Safety system Level Conversion Card ALCC Architect Engineer Specifications Converts speaker level audio at 70VRMS a Desigo Fire Safety Modular system ZAC 40 amplifiers to line level audio Supports input from two 2 audio sources built in prioritization Supports A or B wiring Quantity 63 conversion cards Model ALCC on one 1 audio riser Single channel output at 0.775 VRMS output adjustment capability for each channel Audio path supervision for both channels Built in diagnostic light diodes LEDs UL 864 Listed ULC Listed Product Overview Audio Level Conversion Card Model ALCC converts speaker level audio at from a Model ZAC 40 amplifier or via a Model ZAC 30 with a Siemens panel to line level audio on a Desigo Fire Safety Modular Desigo Modular panel Audio can be provided between the legacy Siemens panel via ZAC 30 and a Desigo Modular system ZAC 40 by also adding one 1 ALCC into the Desigo Modular system line level audio output of a Model ALCC can subsequently be inputted into Siemens Audio Input Card Model AIC of the remote Desigo Modular system Specifications ALCC provides the capability of conducting a global emergency page multiple remote and networked Desigo Modular system nodes with each riser holding a maximum of 63 nodes The emergency page originates at Desigo Modular system where it is broadcast at 70VRMS over an audio riser by Model ZAC 40 on a Desigo Modular system Model ALCC plugs into one 1 in Models CC 2 or CC 5 and can occupy any slot within the either card cage single remote Desigo Fire Safety Modular system node contains one 1 Model which steps the incoming speaker level audio down to line level audio is compatible with the AIC audio input 0.775 VRMS adjustable to AIC digitizes the audio which is subsequently by a Model DAC NET to local amplifier s for over the local speaker zones Model ALCC is of supporting two 2 global paging stations Model ALCC incorporates 2 two independent channels cases where simultaneous paging should occur Model automatically prioritizes the signal on the primary over the secondary channel On board audio circuitry monitors the audio risers for incoming while supervision circuitry reports any issues with audio path via front accessible LEDs If necessary circuitry disconnects its output from the AIC input causing a trouble command to be to the system ALCC relies on the originating amplifier for of the audio risers and on Model AIC for of the connection to Model ALCC Model AIC monitors the presence of signal on its input Model AIC is responsible for reporting audio faults to the Desigo Modular control panel Technologies Division Model ALCC Level Card Sheet 7346 Controls and Settings FOR STATE is powered presence of audio on the riser presence of audio on the riser of the ALCC is sourced from primary user of the ALCC is sourced from primary user fault is present on the primary channel try cycling the on the card fault is present on the secondary channel try cycling the on the card Ratings POWER Back Plane Current Terminal 24V max Back Plane Current Standby Current The Back Plane and Screw Terminal currents represent the maximum currents consumed by Model ALCC the worst case operating condition Back Plane and Terminal currents are only used for of the power supply to Model ALCC Standby current represents the current consumed the 24V battery by Model ALCC in the quiescent mode and is used in the battery size calculation FOR STATE ALCC is not powered certain the card is properly plugged check for failure on PSC 12 CC 5 CC 2 absence of audio on the primary riser riser wiring if audio is intended absence of audio on the secondary riser check riser wiring if audio is intended output is sourced from the secondary riser output is sourced from the primary riser audio channel is fully functional audio channel is fully functional for Ordering TYPE Level Conversion Card NOTICE The information contained in this data sheet document is intended only a summary and is subject to change without notice product s described here has have a specific instruction sheet s cover various technical limitation and liability information of install type instruction sheets as well as the General Product and Limitations document which also contains important data provided with the product and are available from the Manufacturer contained in the aforesaid type of documentation should be consulted a fire safety professional before specifying or using the product further questions or assistance concerning problems that might arise relative to the functioning of the equipment please contact Manufacturer Fire Safety Industry Inc Technologies Division Fernwood Road Florham Park NJ 07932 973 593 2600 2017 New Issue 0
