MW-09-201-S

Alarms, Buzzers, And Sirens Overview

The MW-09-201-S is a piezoelectric chime alarm manufactured by Floyd Bell Inc, belonging to the Audiolarm II series. Designed for panel mounting, this internally driven indicator utilizes wire leads for connection and operates within a DC voltage range of 5 to 25 volts. The component generates an acoustic output at a frequency of 2.9 kHz with a sound pressure level of 70 dB measured at 5 volts and a distance of 61 cm. It consumes between 5 and 25 mA of current during operation. The unit features an IP68 rating for dust tightness and waterproofing, ensuring reliability in harsh environments. Operating temperatures range from -20°C to 65°C, and it holds UL and UR approval agency certifications.
