Siren and strobe installation on alarm Panel Pro

Hi all

I appreciate if you could help me to install siren and strobe (they’re one unit) as it comes with 4 wires and I don’t know which one should get connected.

Current config:
Brand: Networx NX4

Red cable → POS (terminal 7) +12 V supply
Blue cable → COM (terminal 12) Common/negative
White cable → SIREN (terminal 13) Siren control
Black cable → AUXOUT1 (terminal 14) Strobe control

I’d like to connect existing screamer as Alarm 2.

I really appreciate any help on this.

New device: Konnected Alarm Panel Pro 12-Zone
