Product overview

Fire alarm devices for any application


The sounders create an acoustic alarm signal in case of an event. All devices offer a broad range of tone patterns.

  • 16 integrated tone pattern e.g. DIN Tone Sweep-down/Continuous/...
  • 3 sound levels (min/mid/max)
  • Sound pressure level (Up to 99dBA wall devices / Up to 96dBA ceiling devices)
  • Tones are fully synchronized across all loops of a panel
  • Sounders according to EN 54-3
Voice sounders

The devices with voice messages are able to play a precise voice instruction for different events in the building. With help of a voice message, the evacuation process is faster and the building occupants receive clear instructions.

  • Each voice message can be emitted in two languages with an attention tone
  • 15 languages integrated in the device
  • 5 predefined message categories
  • Customer-specific devices (customized order/preprogrammed in factory): Plus 2 languages, Plus 2 message categories, Plus 2 tone patterns
  • All voice messages are fully synchronized in an audible area (across all loops of a panel)
  • Voice messages according to EN 54-3

Addressing two senses – an optical and an acoustical signal – speeds up the alarming and evacuation process. We increase the awareness of the optical signal with a high flash intensity and a very short pulse length. The device has multiple options for brightness which can be adjusted according to the room size.
