The CH-09-201-Q(M) is a panel mount chime alarm from the AudioLarm II series by Floyd Bell Inc. It utilizes piezoelectric technology for audio 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 and emits a frequency of 2.9 kHz. The unit is rated IP68 for dust tightness and waterproofing, with an operating temperature range of -20°C to 65°C. Physical dimensions include a 1.410-inch diameter and a maximum installation height of 1.480 inches, utilizing wire leads for termination.
Verify the specific suffix (M) against official datasheets to confirm terminal type and mounting configuration. Ensure the required acoustic output matches the 70 dB specification at the intended operating distance. Confirm that the 5-25 VDC input range aligns with the system power supply. Validate UL/UR approval requirements for the target application environment.
Select this component when high ingress protection is required for harsh environments due to its IP68 rating. The wide voltage tolerance supports various industrial control voltages without external regulation. The internally driven nature simplifies integration into existing control circuits. Consider the physical size constraints as the unit requires a specific panel cutout for the 1.410-inch diameter housing.
This part belongs to the AudioLarm II series, recognized as a widely used industrial alarm line. The series emphasizes durability and reliability in demanding settings. The manufacturer focuses on solid-state piezoelectric solutions for consistent performance across varying environmental conditions.
