MS-390 Motor Siren — 110 dB Sound Alarm
The MS-390 motor alarm siren produces a sound of over 110 dB, loud enough to be heard from a great distance and to immediately deter any unauthorized entry attempt. It operates directly on 220-240V AC mains voltage, without batteries or additional power sources, making it suitable for residential, commercial, and industrial installations. The electric rotor mechanism offers high reliability and a long lifespan, with minimal maintenance.

How it works and how to install it
The MS-390 siren operates by driving a rotor with an electric motor powered by 220-240V AC: the rapid rotation of the rotor generates the characteristic, loud, and penetrating sound typical of motor sirens. Installation is done by fixing the metal bracket to the wall with screws, connecting the two power wires to the alarm panel's relay output, and tightening the terminals — no advanced electrical knowledge is required, but 220V safety regulations must be observed. The entire process usually takes less than 20 minutes.
Frequently Asked Questions
Can this siren be used with any alarm panel?
Yes, the MS-390 siren connects to any alarm panel that has a relay output capable of switching 220VAC — this is the standard configuration for most alarm panels on the market.
Does it withstand rain or moisture if I mount it outdoors?
The housing is made of durable materials, but the manufacturer does not specify a certified IP rating; for outdoor mounting, placement under a roof or in an area sheltered from direct exposure to precipitation is recommended.
How loud is the sound produced — can someone on the street hear it?
The sound level exceeds 110 dB, equivalent to a jackhammer at close range; the sound is clearly audible within tens of meters, including outdoors or through standard partition walls.

Inspired to create a chair where the backrest and armrests are molded from a single piece of plywood
Inspired to create a chair where the back and arms are moulded from a single piece of plywood, Hecht and Colin describe employing a process similar to that a tailor might use to cut a pattern in fabric. This approach resulted in the beautiful structure wherein the moulded back and arms component is supported by a simple A-frame wood dowel construction. One of the benefits of this design is an increase in comfort due to natural movement in the plywood back.

Made entirely of oak, the Bow Chair is comfortable, visually pleasing and brimming with character. The molded plywood seat is unusually wide in proportion to its depth and a waterfall edge at the front softens contact with the hamstrings.
