NEW Multi-Tone Alarms

Imagine a commercial airline in which alerts for conditions such as low hydraulic pressure, engine over-temperature, and over-speed (when the aircraft exceeds a predetermined maximum speed) would previously require 2 or 3 separate audible alarms. With the new multi-tone alarms, all these conditions could be handled by the same unit. This not only provides cost savings, but also contributes to design simplification. Typical applications include transportation (aircraft, railroad, long-haul trucks), as well as agricultural and construction equipment and industrial applications such as panel boxes. Available in a wide variety of sounds, including chime, fast & slow warble, and fast & slow siren (all available in AC or DC), and three different multi-tone (4 tones in a single package) units, which are available in DC ranges from 6-48 VDC. RoHS compliant, cUL, NEMA 3R/4X/12, and CSA C22.2 no. 94 approved. For samples or more information, please send an email to EngHelpDesk@dee-inc.com, and include you contact information.

Reduce Power Consumption with New Low Power “Green” Audible Alarm Series

admin2 — Wed, 23 Sep 2009 22:04:21 +0000

This new alarm series was developed to help designers build more efficient systems for customers who needed to reduce power consumption in applications such as panel boxes and industrial controls. The power consumption is one of the lowest in the industry. They are available in a wide range of AC and DC voltages. The 120 volt model consumes less than 4 watts, while the 16 volt models consume less that 0.5 watts. Because of its efficient design, the series can produce sound levels up to 105 dB despite its low power consumption. It is available in 20 continuous tone and 72 pulsing tone models, including slow, medium, and fast pulses. Other sound types are also available. This series features an embedded socket and a pluggable terminal block that provides finger-proof safe handling, prevents shock and shorting, and saves assembly time and labor. Screw terminals and flat blade terminals are available options. They are UL and cUL approved, RoHS compliant, and when combined with the accessory gasket, also meet NEMA 3R/4X/12, CSA C22.2 no 94, and IP 66 ratings/requirements.

New Miniature Speaker Series

This new product line was developed to help design and project engineers who need sounds not normally achievable with standard piezoelectric alarms. These new speakers can achieve frequency ratings of less than 2 kHz. This is an advantage in products designed for older consumers because higher frequency hearing capability tends to diminish with age. Designers are also finding that the use of lower frequency audible signals gives them a way to provide a distinguishable sound in their products. Because of this flexiblility, this new speaker is being investigated by manufacurers of products in a very wide variety of industries, including consumer products, industrial machinery, medical equipment, aerospace, and transportation applications. The heart of this speaker is a Mylar speaker diaphragm. Among other adavantages, the Mylar speaker is water and fluid resistant, which makes it ideal for outdoor, medical, and humid applications. This speaker could also mimic certain animal sounds. There are 18 models available and they come in three different types: metal frame, plastic frame, and ultra-compact (low profile) plastic frame. The 8-ohm, 0.25-watt speakers range in size from 11mm to 57mm in diameter and from 3.0mm to 12.5mm in height. The sound levels range from 75 to 92 decibels. All 18 models are RoHS compliant.
