The small size of the Trip 80 series piezo alarm belies its huge sound output. A typical sound-pressure level of 103 to 106 dBa comes out of a case 26 mm in diameter by 22 mm high. As a result, it's a good fit for industrial control, automation, and a myriad of other alarm applications. The alarm operates at a frequency of 2700 Hz ±500 Hz and is available in printed-circuit pin or wire-termination configurations. Operating from a supply voltage of 8 to 16 V dc, the Trip 80 consumes 25 mA maximum. Pricing is $1.50 each in 100-unit quantities. Lower unit prices come with larger quantities. Lead time is stock to four weeks.
