RFXCom transmit on/test signal to Alecto SA-30?

[Marcel458]

I use Domoticz on Centos 7 for a few years. Recently installed a RFXCOM (RFXtrx433 USB 433.92MHz Transceiver Version: Pro XL1/1041).
The smoke alarms we have in our house, brand Alecto, type SA-30 where detected and the notifications are working.
What I would like to do is transmit a signal from Domoticz to these Alecto's like pushing the test button. It seems the "panic switch" only receives, the turn on toggle doesn't trigger the alarm.
Should it be possible to activate the siren by Domoticz?
