E2S upgrades general signalling sounder range
E2S has upgraded the IP ratings of its Alertalarm general signalling sounder range.
All sizes in the family, the A105N (112dB), A112N (119dB) and A121 (126dB) sounders are supplied sealed to IP66 as standard, enabling them to be installed in demanding, dusty or wet environments.
All units have 45 selectable tones and have at least two switchable alarm stages as standard.
There is also the option of a fully programmable four-stage switching version, in which any available tone can be allocated to any of the four stages.
Single-, double-, triple- or quad-stage alarm sequences can be selected from the tones provided.
In addition to having a realistic bell sound, the units can also mimic the traditional siren.
All models are synchronised when operated from the same control supply and are available in a choice of red and grey.
The latest extension to the Alertalarm family is the Spectraalarm range, combined sounder-beacon units that add Spectra beacons to the Alertalarm sounders in a single housing to give visual reinforcement of the audible warning.
A choice of flashing xenon, rotating mirror and LED technologies are available.
