Overview
The SC110MH is a piezoelectric industrial alarm from the SC series, designed for panel mounting. It operates on a voltage rating of 30 to 120 VAC/DC with a continuous tone output. The device emits sound at a frequency of 4.5 kHz and produces a sound pressure level between 68 and 80 dBA. It utilizes screw terminal connections for installation.
Feature Summary
- Generates a continuous audible alert signal using piezoelectric technology
- Supports dual AC and DC power input within the specified voltage range
- Features a compact cylindrical design suitable for standard panel cutouts
Applications
- Industrial machinery status indication
- Factory floor safety alarms
- HVAC system fault signaling
- Commercial equipment monitoring
Procurement Notes
Verify the specific sound pressure level requirement against the 68-80 dBA range before ordering. Confirm that the 4.5 kHz continuous tone matches the intended auditory warning protocol. Ensure the panel mount hole diameter corresponds to the 43 mm specification. Check for any regional certification requirements such as UL or cUL if applicable to the installation environment.
Selection Notes
Select this model when a steady, non-pulsing alarm is required for immediate attention. Compare the 4.5 kHz frequency against other SC variants like the SC110HPR which offers a pulse tone. Consider the 68-80 dBA output range relative to ambient noise levels in the application area. Verify compatibility with existing control wiring for 30-120 VAC/DC operation.
Part Context
This component belongs to the Mallory Sonalert SC series, a line of industrial-grade audio indicators known for reliability. The SC series typically features robust construction for harsh environments. The SC110MH specifically provides a constant tone variant, distinguishing it from pulsed or intermittent models within the same physical footprint and voltage class.
Replacement Considerations
SC110DPR: Offers a slow pulse tone at 2 kHz instead of continuous. SC110FPR: Provides a fast pulse tone with different acoustic characteristics. SC110HPR: Features a fast pulse tone at 4.5 kHz. LSC110N: Delivers a higher volume continuous tone with integrated LED.
