People have to sleep. Your security system doesn’t. Our UL Listed Monitoring Station is on duty 24 hours a day, 7 days a week, ensuring your safety — even when you’re not at home. You don’t even need a traditional phone line. Monitored home burglar and fire alarm systems from First Response have a built-in cellular connection with a backup battery, so even if the power goes out, your home and family are still protected against the dangers of intrusion, fire and smoke.
