I am a new user-installer of Cytech and I m trying to get to know the Panel.
I have installed Comfiguration 3 and trying to program the panel.

I am trying to get in touch with the intrusion system. I installed a fake magnetic contact without EOL resistor and I managed to get the system in alarm.

But.. I measure the output siren and it's 12V although I disarmed the system.
What Should I do with this? Is it normal? If I connect a siren in the terminal block in this configuration will it starts to bell?

If you connect a bellbox to the SRN+/- terminals, it will not sound when idle, ie no alarm
The SRN+ is fixed at 12V and the SRN- is nornallly floaring and will  go to 0V when the siren  is activated, thus supplying 12V.

The Siren connection diagram can be found at
