Yes, the Qolsys security system gives you the option to arm your system in Stay or Away modes. Arming the alarm system in Stay mode will arm all your security sensors except for your motion sensors. This can be customized by programming specific motion sensors to arm in Stay mode (ex. having the basement motion armed in Stay mode). Away mode will arm all of your security sensors including your doors, motions, glassbreaks, etc. Life safety devices, like monitored smoke detectors and carbon monoxide detectors, connected to your system will stay on 24/7.
