LB-07-530-W(S)

Alarms, Buzzers, And Sirens Overview

The LB-07-530-W(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 operates on a DC voltage range of 5 to 25 volts. It 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. The device draws a power current between 5 and 25 mA. Physical dimensions include a diameter of 1.410 inches (35.81 mm) and a maximum installation height of 1.480 inches (37.59 mm). It features wire leads for termination and porting from the top, ensuring reliable operation within a temperature range of -20°C to 65°C.
