CH-09-201-W(F)

Overview

The CH-09-201-W(F) is a panel mount chime alarm from the AudioLarm II series by Floyd Bell. It utilizes piezoelectric technology for sound generation and features an internally driven indicator circuit. The device operates on a DC voltage range of 5 to 25 volts, drawing between 5 and 25 mA. It produces a sound pressure level of 70 dB at 5V measured at 61 cm. The unit has a top port position and measures 1.410 inches in diameter with a maximum installation height of 1.480 inches. It is rated IP68 for dust tightness and waterproofing, with an operating temperature range of -20°C to 65°C.

Feature Summary

• Piezoelectric chime generation with integrated internal driver circuitry
• IP68 rated enclosure providing dust tight and waterproof protection
• Top-mounted port design for directional sound projection
• Wide DC voltage compatibility supporting 5 to 25 volt operation

Applications

• Industrial machinery status indication
• Panel mounted safety alarms
• Equipment operational chimes

Procurement Notes

Verify the specific part number suffix against official manufacturer documentation to confirm termination type and acoustic specifications. Ensure the required mounting hole dimensions align with the 1.410-inch diameter specification. Confirm that the 70 dB SPL meets the necessary audibility requirements for the intended installation environment. Check for UL and UR approval agency listings if regulatory compliance is mandatory for the application.

Selection Notes

Select this component when a durable, weather-resistant chime is required for panel mounting. The wide voltage range allows flexibility in power supply design without external regulation. The IP68 rating makes it suitable for harsh environments where exposure to water or dust is likely. Consider the 70 dB output level relative to ambient noise levels to ensure adequate alert audibility.

Part Context

This model belongs to the AudioLarm II series, which is described as a widely used industrial alarm line. The series focuses on solid-state piezoelectric devices designed for durability in industrial machines. The CH-09-201-W(F) represents a standard chime variant within this lineup, distinct from voice-capable announcers or high-output turbo models.
