CH-09-525-W(F)

Overview

The CH-09-525-W(F) is a panel mount chime alarm manufactured by Floyd Bell Inc, belonging to the Audiolarm II series. It utilizes piezo technology with an internally driven indicator circuit and accepts DC input within a voltage range of 5 to 25 volts. The device operates at a frequency of 2.9 kHz, producing a sound pressure level of 70 dB at 5V measured at 61 cm. Power consumption ranges from 5 to 25 mA. It features wire leads for termination and top port positioning. The unit is rated IP68 for dust tightness and waterproofing, suitable for operating temperatures between -20°C and 65°C. Physical dimensions include a 35.81 mm diameter and a maximum installation height of 37.59 mm.
