Call stations are used to select speaker zones, play voice messages, make live announcements, and monitor and control the Cerberus PACE Compact system.
Call stations are usually installed outside of the cabinet and connected via the 'PACE-Net' network or via 'PACE-Bus' (RS485).
The 'PACE-Net' network transmits digital control and digital audio data. A separate power supply connection is required.
The 'PACE-Bus' (RS485) network transmits digital control data. Separate power supply and analog audio connections are required.
A redundant connection to the call station can be achieved with appropriate measures:
Call station | 1x open circuit | 1x short circuit |
|---|---|---|
PT2001-A1 | Fails | Fails |
PT2001-A1 with PTO2009-A1 | No effect | No effect |
PT2002-A1 | Fails | Fails |
PT2002-A1 with PTO2009-A1 | No effect | No effect |
PT2003-A1 with PTO2008-A1 | Fails | Fails |
PT2003-A1 with PN2009-A1 | Fails | Fails |
PT2009-A1 with PTO2008-A1 Daisy chain | All can fail | All fail |
PT2009-A1 with PN2009-A1 Daisy chain | All can fail | All fail |
PT2009-A1 with PTO2008-A1 Open circuit redundant | One fails, the others are not affected | All fail |
PT2009-A1 with PN2009-A1 Open circuit redundant | One fails, the others are not affected | All fail |
PT2009-A1 with PTO2008-A1 Redundant | One fails, the others are not affected | One fails, the others are not affected Short circuit on audio: all fail |
PT2009-A1 with PN2009-A1 Redundant | One fails, the others are not affected | One fails, the others are not affected |
