MS 390 High Volume Motor Siren

MS 390

It has a stainless metal body.
It is a low consumption, loud large size, excellent sounding motor siren.
The electrical connection is made from the plastic record on the back.
It must be enclosed in a panel in open areas.
It is recommended to operate in an emergency.
After working for 2 minutes, the electricity should be cut off automatically, otherwise the product will heat up and burn. A protection or time relay must be added to the circuit for this process. We recommend our electronic sirens for places that need to be operated for a longer period of time.
