VA4Z SVA4Z SUAUDIO SYSTEMSVA4Z XM S48244Slave module for Public Addressand evacuation compliant withthe EN60849 standard for small tomedium installations• Matrix composed of 4 audioinputs, 1 microphone input foremergency messages, 4 outputsfor 4 independent zones.Optional switching module• Maintains the emergencymicrophone facility to the VA4Z• In case of failure of one or moremaster or slave units, it willautomatically connect one PSSmicrophone station directly toamplifier input, allowing users tomake an all-call announcement• For each zone it allows a+b wiringon same amplifier: when twoloudspeaker lines are used ina zone, they can be connectedto the same amplifier and thismodule will ensure the separateline surveillance, in compliancewith the EN60849 and BS5839 part8 standardsSlave module for Public Addressaudio system• It has the same features asVA4ZS and, in addition, itfeatures automatic gain control:the sensing microphone(PABFMP) can be connected toone of the audio inputs• It will allow VA4Z to carry out anintelligent measure of the noiselevel, adapting the gain of thecorresponding zonesV-EVAC SYSTEMPSS DTPaging microphone consolePSS24DT Code 27835PSS96DT Code 31208PSM8 Code 29972PMM-JB Code 29973VA4Z S VA4Z SU VA4Z XMSCode 27828 294150 dB Inputs/OutputsAudio input impedance10KohmInput sensitivity0dBAudio output impedance50KohmOutput levels0dBMaximum input/output level+14dBuAudio bandfrom 10Hz to 22kHzSampling48kHz 24 bitsDistortionda 0.02% a 1kHzOutput noise102dBu A-weighted100 V Inputs/OutputsMaximum power per channel500W per ogni VA8ZAmplifier gain measurement1kHz 18kHzLine impedance measurement100V 18kHzGround fault measurement12 VDC 0 a 10 MohmsDigital audio messages4 messages, total length 2 mins 11 secsBandwidth8kHzSampling16kHz 16 bitsAlarm input/output contactsAlarm inputs (24V -72V activation) 4Output contacts (error due to lack 4of the line file component)Contact input1 power fault or battery back up faultOutput contact (on/off control) 1Serial connectionsConnection to PSS8491 RS485Connections to message console 2 RS232Connections to PC2 RS232Colour Grey RAL7016 2 RU 19”Dimensions (WxHxD)430x88x230mm17
