I just found another post that says the siren you have is a “re-badged” Philio PSE02 Siren.
I recently created a DTH for that device and it supports playing the different built in sounds like door chime, beep, police, ambulance, fire, emergency and I also added a chirp feature that basically just turns it on and off really fast.
I checked the manual for your device and the commands are similar to the ones in my DTH so it might work, but you’ll have to try it to know for sure.
If it does work, please let me know and post the raw description so I can add it to the list of model numbers it is compatible with and the DTH fingerprint.
The buttons in the mobile app respond properly with Android devices, but I’ve heard you may have to press the buttons more than once to reset them with iOS.
Edit: I forgot to mention that if you open Live Logging before switch DTHs you should be able to see if it was able to configure the device properly when you change it.
You should also open the device’s setting through the mobile app and tap done before trying to use the device. If it doesn’t play post the live logging output.
