Wide area sounder has 750m range

30 March 2010

The A141 high output disaster siren and alarm from E2S is said to be the most powerful device ever produced by the company with an output at 1m in excess of 140dB, louder than a jet engine on full power at takeoff. With a power increase from 100W to 400W, the siren has an effective warning range of up to 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. It 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 siren is powered from either 24VDC or 115/230VAC with mains-powered versions 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. A radio control capability, utilising secure telemetry for additional security, is also available to enable wire-free installation on large sites.
