Your San Francisco smoke detector notifies you that there’s an emergency -- even if you’re not home
The trouble with ordinary smoke detectors is that they only think there’s a possible fire when they feel dense smoke. But, your enhanced San Francisco monitored fire alarms can detect both heat and smoke. As your system senses a fire emergency, they sound off an unmistaken bell, send your mobile device an emergency alert through your mobile app, and ping your Vivint monitoring professional.
