TFA 100

Door/window alarm system with switch key

TFA 100

Simply more safety

  • Loud alarm (approx. 90 dB) upon unauthorized opening
    for approx. 90 sec. (immediate closing won’t stop the alarm sound either)
    with switch key (unauthorized alarm turnoff is not possible)
  • Two alarm functions: Prompt alarm (when present)/delayed alarm (when absent). Thanks to a delay time of approx. 12. sec., entering and leaving the room is possible without initiating the alarm system.
  • An LED is used to indicate previously initiated alarms
  • Fast mounting (easy attachment by means of screws or adhesive tape)
  • Suitable for right-opening and left-opening doors/windows
