PRE-INSTALLATION
The two-digit CAN Bus address for the VTO2004-U2/U3 Option Module (Microphone)
is determined by the two rotary DIP switches located on the back of the
module, as illustrated in Figure 2. The left switch sets the tens digit of the
address while the right switch sets the ones digit of the address. The CAN bus
address is selected by the installer and may be set either before or after
mounting the module. To set the CAN Bus address use a small flat bladed
screwdriver to rotate the center of each switch until the arrow points to the
digit of the address which that switch represents.
Information relevant to assigning CAN bus addresses is provided in the
following Siemens Industry, Inc., Building Technologies Division, documents:
- A6V10315013 FS20 Fire Detection and Voice Announcement System Planning Manual
- A6V10315023 FS20 Fire Detection and Voice Announcement System Configuration Manual
OPERATION
Refer to Figure 3. The VTO2004-U2/U3 Option Module (Microphone) includes a hand-held microphone with a push-to-talk button and a flexible cable, packaged together in a rectangular metal housing with a surface-mounted Microphone Interface Board (MIB pictured in Figure 2). To use the microphone, the operator depresses and holds the push-to-talk button until the control system enables the announcement to be transmitted. The operator continues to hold the button for the duration of the announcement. To prevent audio feedback “squeal” during announcements, the VTO2004-U2/U3 incorporates a tune-down relay to mute the nearest loudspeaker(s) while the push-to-talk button is depressed and the microphone is active.
Controls and Indicators
The “Preannouncement Active” LED and the “Ready to Page” LED are located on
the front panel of the VTO2004-U2/U3 Option Module (Microphone). The
“Preannouncement Active” LED illuminates when the operator presses the “push-
to-talk” button on the microphone to request an audio connection to the
FV2025/2050 Fire Voice Control Panel. When the audio connection is made, the
“Preannouncement Active” LED extinguishes and the “Ready to Page” LED is
illuminated. At that point the operator can talk over the microphone. The LED
remains illuminated until the operator releases the push-to-talk button or is
overridden by a higher priority audio message.
