A well-composed alarm system will also work well in emergency situations (such as fire, flooding, and gas leak). Installing the appropriate detectors of additional protection will enable you to respond rapidly. After detecting a threat, the devices will transmit a signal to the alarm control panel, which, in addition to triggering the siren, will immediately start e.g., forced ventilation (if there is a large amount of smoke or gas) or close the water cutoff valve (if a flood is detected) and immediately notify you that call for help is necessary. Every second counts.
