E2S A141 high output disaster siren and alarm
With an output at 1m in excess of 140dB, louder than a jet engine on full power at takeoff, the new A141 high output disaster siren and alarm from E2S is the most powerful device ever produced by the company - so far.
With a power increase from 100W to 400W, the output of the A141 is substantially higher than the A140 it replaces, giving it an effective warning range of between 500 and 750m depending on the atmospheric conditions. The unit has a choice of 32 user-selectable warning tones and with second and third stage alarm capability, it is ideal for use in quarries, on large industrial and petrochemical sites and for civil defence requirements. The A141 generates multiple internationally recognised alarm tones including fire, security, civil defence, alert, COMAH (SEVESO II) toxic gas alarms and disaster warnings for flood, tsunami, tornado and other severe bad weather conditions.
The A141 is powered from either 24VDC or 115/230VAC. The mains-powered versions can be fitted with battery backup to enable it unit to operate for up to 30 minutes without mains power; AC power and battery voltage can be remotely monitored for potential faults. Radio control capability, utilising secure telemetry for additional security, is available to enable wire-free installation on large sites.
Both AC and DC versions feature low start-up inrush current and low operating current draw, and, unlike traditional electro-mechanical warning devices, they are lightweight, require no maintenance and offer the reliability, low energy consumption and long life associated with solid state devices.
