23. Mute Current / Next Alarm
A network failure alarm will be indicated by providing 3 beeps over both audio outputs every 30 seconds but only when Permanent
Alarm Mute is set to Alarm Tones Enabled (Permanent Alarm Mute is set to Alarm Tones Disabled by default). A network failure
indicates the unit is not registered to the SIP server or there is a communication failure with the gateway. The three beeps can be
muted by clicking on "Mute Current / Next Alarm" button in the IP Programming software or pressing and holding the Reset button
for five seconds. The Status LED will continue to flash to assist troubleshooting. The alarm beeps can also be permanently disabled.
See Permanent Alarm Mute below. Factory Setting: Disabled
24. Permanent Alarm Mute
Permanent Alarm Mute is set to Alarm Tones Disabled by default, so network failure alarms will not be indicated over the audio
outputs. Only the status LED will flash to indicate the network failure. To enable alarm tones over the audio outputs, select Alarm
Tones Enabled.
25. Programming a Username and Password to Restrict Access to Programming
To increase security, a username and password can be programmed to limit access to the PA-250-IP using Viking IP Programming
software. When no username and password are programmed and the security code is still set to default (845464), the PC software
will not require a username, password or security code when connecting to the PA-250-IP. If the PA-250-IP has been programmed
with a username and password, a pop up window will ask for the username followed by the password. If the unit's security code has
been changed from default (845464), it will then prompt for the correct security code.
If the username and password are unknown, they can only be erased by resetting all network parameters to default with the Reset
button (see section E on page 7). If the username and password are known but you wish to erase them, that can be accomplished by
exporting the data from the PA-250-IP, resetting all network parameters to default with the Reset button (see section E on page 7) or
clicking on "Clear IP Settings" and then importing the data back into the PA-250-IP.
26. IP Firmware
Update IP is currently not available. The ability to update IP firmware will be made available in a later release of Viking IP
Programming software. If an IP firmware update is needed, Viking Technical Support will assist in updating the IP firmware.
27. Unit Firmware
If new Unit firmware is available, after opening the programming software a pop up window will ask if you would like to update the
firmware. Another way to update is accomplished by clicking the "Update Unit" button. You can then browse to the folder that contains
the HEX file for updating the unit's firmware. This method is typically only used when Viking Technical Support has sent you updated
firmware.
