Wall Mounting Sounder
  • General
  • Feature
  • Specification
The NS series of wall mounting conventional sounders have been engineered combining rugged construction and acoustic efficiency. This results in a low current sounder with high volume, wide angle sound distribution providing good audibility in all directions. These sounders are suitable for many applications from offices to hotels, industrial plants to hospitals. The internal solid state electronics provide the user with a choice of either continuous or sweeping tones at a variety of frequencies and volume levels. The NS series sounders are available in a choice two colours - red or white and are supplied with either 3 or 14 preconfigured sounder patterns/tones. Each sounder can be matched to the environment using one of the available bases, NBL base – IP44, NBD base IP55 and NBS base IP66. The NS sounders can be integrated onto systems using other sounders or strobes from the Morley-IAS portfolio or other compatible systems.
