The design of the ORDONE smoke exhaust control panel is the result of research into the typical configuration of a smoke exhaust system in a residential building.

The ORDONE smoke exhaust system was specially designed for use in this configuration.
It is built of a signal panel bearing the reference ORDONE and connection boxes for installation either on each building storey (B.E.A = addressable storey box) or close to the elevator machinery (B.N.S = non-stop box), or near to the exhaust unit (B.C.E = exhaust control unit).
