E2S Offers High-Output Alarm With 750m Range

The new A141 high-output disaster siren and alarm from European Safety Systems (E2S) delivers an output of more than 140dB at 1m, which is louder than a jet engine on full power at take-off. With a power increase from 100W to 400W, the output of the A141 is higher than the A140 it replaces, giving it an effective warning range of between 500m and 750m, depending on the atmospheric conditions. The unit has a choice of 32 user-selectable warning tones and, with a second- and third-stage alarm capability, it is suitable for use in quarries, on large industrial and petrochemical sites and for civil defence requirements.

The A141 generates multiple 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 the 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 available to enable wire-free installation on large sites. Both the AC and DC versions feature low start-up inrush currents and low-operating-current draws. They are lightweight, require no maintenance and offer the reliability, low energy consumption and long life associated with solid-state devices, according to the company.

What is Class I Division 2?

Image
A Class I Division 2 is a location: (1) In which volatile flammable gases, flammable liquid-produced vapors, or combustible liquid-produced vapors are handled, processed, or used, but in which the liquids, vapors, or gases will normally be confined within closed containers or closed systems from which they can escape only in case of accidental rupture or breakdown of such containers or systems or in case of abnormal operation of equipment, or (2) In which ignitable concentrations of flammable gases, flammable liquid-produced vapors, or combustible liquid-produced vapors are normally prevented by positive mechanical ventilation, and which might become hazardous through failure or abnormal operation of the ventilating equipment. Class I Division 2 Classification Class I Division 2 refers to the ANSI/ISA 12.12.01 standard. This standard was previously UL1604 until UL recommended the newer ANSI/ISA standard be used and that all hazardous location products be certified under this standa

FUSE SIZING CONSIDERATIONS FOR HIGHER EFFICIENCY MOTORS

Image
When selecting the proper fuse for short circuit protection in motor starting applications, it is important to not only ensure that the fuse will not nuisance open during motor start up times, but also that the fuse will coordinate as required with overload relays. When sizing fuses between 125% and 150% of the motor nameplate current, several advantages, including ease of coordination with an overload device, a smaller disconnect, and increased short circuit protection from a lower fuse rating, can be achieved. However, if sizing at this level prevents the motor from starting, it may then be necessary to increase the fuse ampere rating and it then becomes important to know the NEC sizing limitations. As of June 1, 2016, the US Department of Energy has mandated that newly manufactured electric motors will need to meet NEMA Premium® efficiency standards. As motor efficiencies increase, motor locked rotor currents can also be expected to increase. In addition to this, with across-the-lin

7/8 16UN Connectors that Provide 600 Volts and 15 Amps

TURCK announces new A-Size 3 and 4-pin 7/8 16UN powerfast™ connectors that provide up to 600 Volts and 15 Amps of power. These IP67 rated connectors provide a modular wiring system designed to handle high current applications for machine power distribution, while providing resistance to vibration commonly associated with conveyors, motors and material handling applications. The cordsets are available with a tray rated, exposed run PVC flexlife ® cable, with or without STOOW rating, and 14 AWG wires that allow you to replace hard wiring with a robust, quick disconnect system that saves the time and money spent installing a conduit system. The A-Size powerfast line offers male and female, straight connectors, standard and custom lengths, and pigtails or extensions. To make the system complete, fully encapsulated mating receptacles, with 1/2”-14 NPT mounting threads are available.
