Siemens VTO2004-U2 VTO2004-U3 Option Module (Microphone), Installation Instructions

INSTRUCTIONS VTO2004 U2 U3 Module Microphone VTO2004 U2 U3 Option Module Microphone illustrated in Figure 1 is installed in the Fire System to enable firefighters and other safety personnel to make announcements and broadcast safety during emergencies and drills The VTO2001 U2 U3 can be installed in either or both the Fire Voice Control Panel or the VR2005 U1 Remote Microphone station The VTO2001 U2 U3 is intended for use in dry protected environments only principal features of the VTO2004 U2 U3 Option Module Microphone include microcontroller with remote firmware update capability Push to talk voice operation with centralized contention resolution Tune down relay muting of local speakers to prevent audio feedback squeal Automatic microphone gain control Microphone supervision of short and open circuit conditions Continuous status monitoring with automatic fault reporting EMC compliant ROHS compliant and meets performance specifications within the range Can be used in UL and ULC markets 1 Option Microphone two digit CAN Bus address for the VTO2004 U2 U3 Option Module Microphone is determined by the rotary DIP switches located on the back of the module as illustrated in Figure 2 The left switch sets tens digit of the address while the right switch sets the ones digit of the address The CAN bus is selected by the installer and may be set either before or after mounting the module To set the Bus address use a small flat bladed screwdriver to rotate the center of each switch until the arrow to the digit of the address which that switch represents relevant to assigning CAN bus addresses is provided in the following Siemens Industry Inc Technologies Division documents A6V10315013 FS20 Fire Detection and Voice Announcement System Planning Manual A6V10315023

Option Module Microphone includes a hand held microphone a push to talk button and a flexible cable packaged together in a rectangular metal housing with a Microphone Interface Board MIB pictured in Figure 2 To use the microphone the depresses and holds the push to talk button until the control system enables the announcement be transmitted The operator continues to hold the button for the duration of the announcement To audio feedback during announcements the VTO2004 U2 U3 incorporates a tune down to mute the nearest loudspeaker s while the push to talk button is depressed and the microphone is and Indicators Active LED and the to Page LED are located on the front panel of the Option Module Microphone The Active LED illuminates when the presses the button on the microphone to request an audio connection to the Fire Voice Control Panel When the audio connection is made the LED extinguishes and the to Page LED is illuminated At that point the operator can talk the microphone The LED remains illuminated until the operator releases the push to talk button or is by a higher priority audio message HOUSING LED LED BUTTON MICROPHONE CABLE 3 view of the VTO2004 U2 U3 Option
