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.

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 of two colours - red or white and are supplied with either 4 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.
