eRotor electronic sirens are simplified electronic sirens designed by Technologie 2000 and assembled by SiRcom GmbH. These sirens are made as electronic replacements for mechanical sirens, and are unsuitable for frequent activation. This makes them a full replacement for namely the FP (fire-protection) mechanical sirens, intended only for the convening of firefighters. However, as eRotor allows the user to activate all standard features, as it would be with ordinary electronic sirens via Its control panel, the siren can serve for mass warning as well. Despite all this, the company itself recommends using the MAESTRO series instead, if the siren is intended to be used more often.

 
The siren, if compared to MAESTRO, has a smaller local control panel, with simplified interface. The siren most likely misses all advanced features of both MAESTRO and PREMIUM series, but retains all necessarily needed functions. It can be also connected to SSRN system, and therefore controlled remotely. The siren comes in 250W, 500W, 750W and 1500W series, of which 500W is considered to be the equivalent of mechanical siren.
