MS Series Industrial Motor Alarm Sirens
Motor-driven alarm sirens in MS-190, MS-290, MS-390, MS-390P and larger two-way designs. Catalogue voltage and sound ratings vary by model; select the required supply and installation arrangement before ordering.
Specifications
Product Overview
The MS series uses a motor-driven siren for audible signaling. The source catalogue separates the smaller MS-190, MS-290, MS-390 and MS-390P designs from the larger MS-490, MS-590, MS-690 and MS-790 two-way sirens. The latter group is illustrated with AC 110V or AC 230V options and different sound ratings. Materials also vary across the family, with iron, ABS, aluminum and steel listed rather than one common enclosure specification. Use the model-specific drawing to plan mounting. Supply voltage, operating duty, sound measurement conditions and weather protection must be matched to the installation; the legacy introduction's single 110dB statement does not describe every model.

Frequently Asked Questions
Which models provide two-way sound transmission?+
The legacy description identifies MS-490, MS-590, MS-690 and MS-790 as two-way sirens. Confirm the required mounting orientation and model drawing.
Is every MS siren rated at 110dB?+
No. The catalogue shows 120, 123, 126 and 130dB for MS-490 through MS-790 respectively, without a measurement distance. A single 110dB introduction cannot be used as the family rating.
Can it run continuously?+
The source makes a general more-than-40-minute operating claim but gives no model-specific duty cycle or thermal limits. Request the duty rating for the selected siren before planning continuous operation.
Is 230V the same listed option as 220V?+
Do not substitute automatically. The general text lists 220V, while the larger-model image lists 230V. Specify the exact model, mains voltage and frequency in the inquiry.
What should a purchasing inquiry include?+
Provide model, voltage, quantity, installation location, required duty cycle and any destination-market documentation. Current delivery and sample terms are confirmed with the quotation.
Applications
Factories, warehouses, lifting equipment and industrial signaling are listed uses. Suitability for ships, fire-alarm systems or hazardous locations requires model-specific documentation and installation assessment; it is not established by the general catalogue.
