A metal housing with siren eletru00c8nica embedded in plastic enclosure, with the installation system, sealing and safety.Arranged so the components of electrical and electronic siren, and a printed circuit board (17) connected to loudspeakers (5), a safety sensor (tamper) (6), and a device switch (11) are protected in a metal housing shielded (1) fixed such as embedded in a cabinet plu00e1sti CO (26).The horn is installed after the withdrawal of the plastic enclosure (26) fixed on the wall from its rear plastic cover (27) together with the base metal (18) of the rear armored box (1), and if the latter hinged down, exposing the assembly to the connections of the electronic The printed circuit board (17) with the electronic alarm module (m) and the battery (b) to be used.When the siren deactivated by the switch (11), preventing firing sound. After the closing of the armored box (1), followed by the closing of the plastic enclosure (26) through the switch (11) is activated, the siren, for adjustment of time and test shot.
