Frequently Asked Questions
While our security hub includes a built-in alarm siren, purchasing a secondary siren provides an extra layer of protection in parts of your home that may be out of earshot of the main siren. If you live in a larger home, placing an extra siren in locations far away from the main siren can provide several benefits, including:
- Notifying you that an intruder has entered an area of your home.
- Notifying you when an environmental emergency (such as a fire or flood) has started somewhere around your home.
- Scaring away potential intruders. Dogs barking, alarms, and other loud noises are known to be effective deterrents against intruders.
Our secondary alarm system works quite simply. Like the other pieces of equipment in our system, it connects to the hub via a wireless connection, such as radio frequency or Z-wave. Because all of the equipment in our system uses this same connection, whenever any one sensor is triggered, it will send a notification to the hub, which will then trigger an alarm on both the hub and any secondary sirens. While the alarm is going off, the hub will send a notification to the monitoring team, who will then reach out to you via phone call or text to ensure everything is okay. If you need help or are unable to answer, the monitoring team will dispatch authorities to your home.
Our secondary siren is designed to be as loud as possible, to serve the double purpose of notifying you when trouble is nearby, and hopefully scaring that trouble away.
