Clean lines, full protection.
Self-powered Grade 3 outdoor siren with 122 dB, polycarbonate housing and galvanised steel inner cover. Available with a white or grey body and a flash in blue, red, green, clear or alternating red and blue.

Cable protection
The siren sounds if the wires to the control panel are cut or short-circuited, or if the voltage drops below 10 V.
Dual tamper
One on the cover and one on the base, against attempts to open it or remove it from the wall.
Installation without the rush
It is fitted before the control panel is connected and activates at first power-up. It also has a test mode.
