Line supervision setting for ONE series device
Support Handbook - ONE series
1 DESCRIPTION
This documenttion explains how to settup the frecuency and attenuation of the line
suppervision at ONE series devices on detail. Line supervision is a method used by the
device to meassure the current impedance and check the correctperformance at speakers
lines.
LINE SUPERVISION FRECUENCY CHANGE
Follow those steps to proper config the line supervision frecuency
1. From main menu, hold BCK botton for 3 sec.
2. Press OK + BCK at the same time for 3 sec.
3. Enter the Access ID and press OK. See APPENDIX I for the correct reference.
4. Enter Login level 3 access (with password 0003 by default).
5. Change the frequency value with the "up" and "down" arrow keys between 19 (kHz)
and 24 (kHz). By default the equipment is set to 19 kHz.
6. Press BCK until recover main menu.
3 ADJUSTING THE LINE MONITORING VOLUME.
To adjust the volume of the line monitoring, proceed as follows
1. From main menu, navigate with the "right" and "left" keys until you find the
"Configuration" option. Press "Ok".
2. Enter Login level 3 access (with password 0003 by default).
3. Navegate until the path “Configuration/Zones”.
4. You must perform the following procedure with each of the areas you wish to monitor

6. Press OK + BCK at the same time for 3 sec.
7. Enter the Access ID and press OK. See APPENDIX I for the correct reference.
