Protect sounder max. 116 dB(A)

• Excellent robustness – Cast aluminium housing guarantees long lasting use in tough applications
• Outstanding perceptibility – Ideal radiation characteristics and high penetration of acoustical obstacles reduce the required number of devices
• Multi-voltage-power supply – Made to connect with different voltages, no need to stock various units
• Selectable tone – 80 different tones, 3 additional tones externally selectable
• Reducible sound pressure level – up to 30 dB, internally or externally selectable
• Pre- & main alarm – Preventing shock reactions by pre-alarming due to reduced sound pressure level
• Safe & easy handling – Designed with unlosable seal and screws to significantly shorten wiring and installation times

Sounder max. 108 dB(A)

The sounders from the DS 5 series can be used for tough demands under industrial conditions and as universal alarms. The sounders which are suitable for use both indoors and outdoors, generate warning signals in 31 different tones that can be selected with the aid of an internal switch. Optionally, a maximum of 3 additional tones can be switched to using an external controller. In addition to the factory settings, the tone combination can be individually selected by on-site programming (tone 32). Custom versions are available for special applications. The GL version is especially resistant to shock and vibration

Sounder max. 114 dB(A)

The sounders from the DS 10 series can be used for tough demands under industrial conditions and as universal alarms. The sounders which are suitable for use both indoors and outdoors, generate warning signals in 31 different tones that can be selected with the aid of an internal switch. Optionally, a maximum of 3 additional tones can be switched to using an external controller.

The GL version is especially resistant to shock and vibration

Sounder max. 108 dB(A)

• 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)
