Combined acoustic/optical alarm device, red flash, white housing


Combined acoustic alarm signaling device is EN 54-3 compliant with additional optical display, in white housing, and offers a selection of 32 signal tones including the DIN tone and other countryspecific tones. All tones comply with EN 54-3. Tone configuration takes place via a 6-pin DIP switch. Up to two different signal tones may be activated. Signaling device with flat base, suitable for wall and ceiling mounting.
The integrated optical display with red signal flash is only authorized under EN 54-23 in open category O for 24–29 V DC operating voltage. Below 24 V DC, the device is classified as an acoustic signaling device with additional display. To help define your conventional Visual Alarm Devices (VADs) requirements in line with the EN54-23 standard, we have developed an easy to use online guide. Simply enter the room dimensions and ambient light conditions and the guide will help your device selection:

  • EN 54-3 compliant
  • Cat. O under EN 54-23
  • Synchronous sound and flash trigger
  • Volume adjustable to 2 levels at the device
  • Suitable for wall and ceiling mounting

Additional Information:

Not suitable for use outdoors or in damp areas. Please use therefore the optional bases and accessories (Part No. CWR, PS188, PS189). Use of the deep IP socket reduces the dB output by an average of 4 dB. Replacement for Part No. 766240.
