I bought the siren hoping for the best. Unfortunately, I'm pretty disappointed in how it actually functions.
Almond+ Compatibility:
This is gets added to the Almond+ system as a functional, binary, 'on/off' siren. It is very loud.
The 'five tones' and 'three volumes' cannot be configured if included in an Almond+ system.
The only application for this device is an alarm.
Vera3 UI7 Compatibility:
I was able to include the siren into my Vera 3 system. UI5 handles it the same way as the almond+ (on/off '_applianceModule' with default noise & volume).
The mios UI7, however, supports 'Device Configuration options'. By changing one of the configuration settings (a rather convoluted process) I was able to change the noise and volume.
There are at least two disappointing consequences for this architecture.
1) The device has to be 'configured' every time you want to select a different tone/volume. It is not an 'instant' process.
2) There is no straightforward programmatic means to trigger the different tones (yet?). It is not a simple matter to use this for multiple purposes. (i.e. I was envisioning it as a cat trainer and a door chime)
Conclusion
Without some work done by Securifi (or Vera) to support the 'device options' configuration process, this will only ever be a single tone siren best suited to 'alarm' applications. Even supposing eventual controller support, the lowest configurable volume is unpleasantly loud, and users may want to muffle it mechanically, or by adding an in-line resistor the speaker.
