| Weight | 1 |
| Technical specification | DS 5-DN / 230 VAC Standard version Sounder with 2 externally controllable volume levels. Wherever sounders need to be operated virtually 24 hours a day for alarm purposes, e.g. in port areas, container terminals, conveyor belts in coal mines or for supplying power stations, it is important to disturb local residents as little as possible. This is especially the case in the evening and at night, when the ambient noise level is also lower. Can also be used to avoid startled reactions by starting the alarm with a reduced sound level and increasing it in steps (soft alarm). The sound level can be reduced by an external controller or via a floating contact. The reduction may be preselected during the installation in accordance with local conditions (0 to –20 dB). |
