5816 is a type of emergency alarm system typically used in residential properties. It features an emergency response system that is connected to a monitoring center, which can provide police, fire, and medical emergency assistance. The alarm is triggered by a panic button, smoke detector, carbon monoxide detector, glass break sensor, or other monitoring devices connected to the system. In the event of an emergency, the alarm is activated and an automated system dispatches emergency responders to the location. Remote access to the alarm can be provided via an app, allowing the user to check the status of their system as well as control settings from a distance.
