When connected to a Chuango alarm system controller and an incident occurs, the 105S siren will go off with the strobe light flashing. For smaller premises, the unit can work as an independent on-site controller with other accessories, such as remote controls, door/window contact sensors and PIR motion detectors. Two for one, not a bad deal.

The piano finish and streamlined design make Chuango 105S an art of its own, and it beacons a sense of serenity and security (in a non-intrusive blue hue), when functioning as an idle system controller. When connected to a Chuango system controller as a siren, it stays unobtrusive and behind the scene if not triggered.
