Alarm Systems

Alarm Systems

For the highest security standards in your poultry house

Modern houses for poultry production are equipped with technical management aids for monitoring and notification purposes. The real-time monitoring of the house enables farm managers to react instantly in case of problems and are thus able to prevent any further damage. Big Dutchman alarm systems raise the bar regarding security requirements and functionality. 

AC Touch

For the highest security standards

The alarm device AC Touch is at the forefront of a whole new generation of alarm systems. Instead of a key, AC Touch is accessed using a fingerprint sensor. This ensures that changes to settings and acknowledged alarms can be traced back to the responsible person with absolute certainty, which is an excellent advantage on farms with several employees.

Furthermore, the large coloured display makes the alarm device easy to use. All alarm inputs and functions are displayed clearly and can be easily adjusted. Another important feature is the ‘black box’, which cannot be deleted and saves all alarms and activities.


  • Provides secure access using a fingerprint sensor
  • Tracks and records changes made by different employees
  • Triggers alarms for various criteria, such as temperature, fire and motor failure
  • User-friendly
  • Alarms can be recorded and cannot be deleted for one year


  • 10 analogue or digital alarm inputs, including temperature alarm, fire alarm, motor failure
  • All inputs are fail-safe in case of wire breaks (as an option, also for short circuits)
  • 10 relay outputs actively switch on emergency fans or MultiStep groups, dependent on temperature limits or alarm notifications
  • The temperature is monitored using temperature profiles which can be pre-configured or set up individually (broilers, layers)
  • Temperature monitoring registers both sudden temperature changes and temperatures below or above the absolute values with regard to the current outside temperature
  • Secure identification using a fingerprint sensor, able to cater to up to 20 users with different access rights
  • Progress curves of all alarms of the past 30 days can be displayed
  • Long-time storage that cannot be deleted for one year
  • Phase failure monitoring (optional) reports power failures
  • Backup battery including monitoring of the battery status
  • Automated test alarm
  • Less important alarms can be muted for the night
  • Integrated microphone records alarm messages

AC 3-T A

Simple, robust and easy to use

AC 3-T A has a wide functional range and is equipped with an extremely long-lasting battery. This ensures the highest operational reliability, especially in regions where power failures are common.

AC 3-T A consists of two housings to save space when installing the operating unit in a control cabinet door. The second housing holds the battery and the phase control (optional) and can be mounted in the control cabinet. All relevant functions are structured very concisely and are therefore very easy to use. The battery housing is also ideally ventilated.


  • Equipped with a broad functional range
  • Powered by a battery with an extremely long life
  • Dependable in areas with frequent power outages
  • The design of the unit saves space
  • User-friendly


  • Minimum and maximum temperature alarms can be set individually and alarms are generated if the temperature is below or above these target values
  • Two alarm inputs are available - one for the climate and production computer and one for phase monitoring and the protective motor switch of the control cabinet
  • Three different backup thermostats switch on selected fan steps, if a climate controller fails
  • Active battery monitoring ensures that the status of the battery is checked every two minutes
  • Contacts of the backup relay remain switched on for up to six hours after a power failure
  • Alarms can be switched off using the key in the unit until the issue has been solved
  • The integrated testing and memory function guarantees that the alarm system reminds the farmer to adjust the minimum and maximum temperatures in rearing and broiler houses according to the birds’ age
