3-21-010 Motor Driven Sirens Motor Driven Sirens The E2S range of motor driven sirens oer the traditional “air raid” type warning signal designed to give eective warning over wide areas. The powerful low frequency sound is ideal for covering long distances and is instantly recognisable. The simple, rugged design is low maintenance and oers the lowest cost solution to disaster warning applications such as COMAH (SEVESO II) toxic gas alarms, ood and tsunami warning, security alert, civil defence, tornado and bad weather alert. Using the matching control panel, these sirens can produce up to 3 distinct warning tones and there are a variety of control options to suit customer requirements. Controls can be linked by hard wire, telephone cables or radio control using digital telemetry to create a secure communication network. E2S has considerable experience in this eld and is able to oer full pre and post installation support including assistance with siren selection. A robust, rugged cast aluminium siren with a very powerful low frequency output. Ideally suited for use in factories, reneries, quarries, construction and industrial sites, as well as both underground and surface mining. Precision machined aluminium body with all weather enclosed, continuously rated motor. Ideally suited for use in factories, reneries, quarries, construction civil defence and industrial sites, as well as both underground and surface mining. All weather enclosed motor is ideally suited for outdoor use. This siren would be used for audible warning at reneries, oil rigs, in the event of res and open-cast mining operations. This precision machined unit produces a powerful dual low frequency sound that is ideal for long distance signalling. • Maximum Output: 135 db (A) @ 1m • Tones: Continuous or Wail Tone (when supply is switched on/o) • Frequency: 560Hz • 1 Km eective range • Voltages: 400v 3 Phase • Motor Power: 2.2kW • Duty: Continuous • Enclosure Material: Cast Aluminium • Colour: Grey, other colours available • Operating Temperature: -20 to +40°C • Storage Temperature: -40 to +70°C • Relative Humidity: 90% at 20°C • Weight: 50Kg • Maximum Output: 140 db (A) @ 1m • Tones: Continuous or Wail Tone (when supply is switched on/o) • Frequency: 560Hz • 1.5Km eective range • Voltages: 400V 3 Phase • Motor Power: 4kW • Duty: Continuous • Enclosure Material: Cast Aluminium • Colour: Grey, other colours available • Operating Temperature: -20 to +40°C • Storage Temperature: -40 to +70°C • Relative Humidity: 90% at 20°C • Weight: 68Kg • Maximum Output: 145 db (A) @ 1m • Tones: Continuous or Wail Tone (when supply is switched on/o) • Frequency: 560Hz • 2.5Km eective range • Voltages: 400V 3 Phase • Motor Power: 7.5kW • Duty: Continuous • Enclosure Material: Cast Aluminium • Colour: Grey, other colours available • Operating Temperature: -20 to +40°C • Storage Temperature: -40 to +70°C • Relative Humidity: 90% at 20°C • Weight: 118Kg Part codes: Part code: Other voltages available on request.
