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.
