Transducers USA Introduces New Solid-State Buzzers with Low Frequency

Transducers USA, an industry leading supplier of audible signal devices, has announced the introduction of a new solid-state piezoelectric transducer that operates at a low frequency.


This new solid state buzzer has been designed to respond to the need for upgrading and replacing electro-mechanical transducers which have movable armatures.

The solid-state piezoelectric design feature eliminates the moveable plunger in electro-mechanical devices. With no moving parts, the solid-state circuitry promises an almost infinite life for ceramic piezo audio output.

The new Model TRIP-2612P(S) from Transducers USA delivers 400 Hz at a minimum of 95 dB with a standard 12DC. The problem with higher frequencies used in audible alarm notification appliances is that many aging individuals lose their ability to hear. Lower frequencies are better heard by those with hearing loss, such as the elderly in nursing homes.

The NFPA has been dealing with standardizing low frequencies in alarm devices and notifiers for many years now, but the current trend is to use low frequency sounders. Since hearing loss is not apparent among occupants of a hotel, for example, the NFPA 72: National Fire Alarm and Signaling Code now requires low frequency sounders must be installed in all sleeping rooms, not in corridors. This applies also to dormitories, assisted living and retirement facilities, apartments, condominiums, colleges, universities and other buildings with sleeping areas. The TRIP-2612P(S) from Transducers USA meets this NFPA code requirement.

The TRIP-2612P(S) is RoHS compliant with a flame-retardant plastic cover. It provides easy and stable PC board mounting and connections. The unit measures 26mm x 19mm off the PC board. The TRIP-2612P(S) is priced at $3.90 each in 1K quantity. Transducers USA can provide modifications to this solid-state device, as well as custom designs to suit special application needs.

To compare the sounds of high and low frequency transducers, and those from a solid-state vs. an electro-mechanical device, listen to the Live Presentation on the Transducers USA website.
