and should ring even if panel is compromised.
In almost every wired system the bell is held off ( kept silent ) as long as the cable to the panel is intact and the panel is providing a hold off voltage to the siren. Amything that prevents the hold off signal reaching the siren will cause the siren to operate on it's internal battery. The battery is a rechargable battery kept fully charged by power ( 12 volt ) from the control panelAlso with a wired system In the same situation can an intruder unwire. I personally have a wired and it doesn't seem so easy
isn't it easy for a burglar to just unplug the panel quickly and that's that ?
The intruder can actually enter through the entry route and as long as he unplugs the control panel within the permitted entry time (in my case 20 secs) then that's that... the siren doesn't ring
Am I correct?
