“Arm Stay” on an ADT System If you currently use ADT—or are thinking about getting an ADT security system—understanding its different arming modes is essential to keeping your home properly protected. One of the most commonly used settings is Arm Stay, a mode designed specifically for times when you and your family are inside but still want strong perimeter security. Knowing how and when to use Arm Stay ensures that you maximize protection without unnecessary false alarms.
What Does “Arm Stay” Mean?
Arm Stay is a security mode that activates the perimeter sensors around your home while bypassing the interior motion detectors. This allows you to freely walk around inside without triggering the alarm.
Here’s what the system monitors when Arm Stay is activated:
Armed (Perimeter)
- Door and window sensors
- Glass break detectors
Bypassed (Interior)
- Indoor motion sensors (PIR motion detectors)
Because the interior sensors are inactive, you can move from room to room comfortably—perfect for nighttime use or daily routines. However, the moment a protected door or window is opened, the system immediately begins its alarm countdown.
Top 3 Things You Must Know About Arm Stay on an ADT System (And When to Use Stay Mode)
The name “Stay” itself is a reminder: use this mode when people or pets are staying inside the house. Arm Stay is ideal in several common situations:
1. Sleeping at Night
This is the most popular use. You want strong protection from break-ins, but you also want the ability to move around the house without triggering indoor sensors.
2. Working or Relaxing at Home
If you’re spending the day inside—working, watching TV, cooking, or taking a nap—Arm Stay keeps your perimeter secured without disrupting your movements.
3. Homes With Large Pets
Standard motion detectors can be triggered by larger dogs. Using Arm Stay lets your pets roam freely while maintaining essential perimeter protection. Your furry friend stays comfortable, and you stay worry-free.
Arm Stay vs. Arm Away: What’s the Difference?
To fully understand your system, it’s important to know how Arm Stay compares to Arm Away.
| Feature | Arm Stay | Arm Away |
|---|---|---|
| Intended Use | When people or pets are inside the home | When the house is empty |
| Armed Sensors | Doors, windows, glass breaks | Doors, windows, glass breaks AND interior motion sensors |
| Motion Sensors | Bypassed | Active |
Arm Away is the higher-security mode since it activates interior motion sensors as well. This mode is best used when no one is home.
Some ADT models also offer variations like:
Instant Arm / Night Stay
This is a version of Arm Stay on an ADT System that removes the entry delay. If someone opens a protected door or window, the alarm sounds immediately. This mode is excellent for overnight use when you want maximum perimeter protection.
Maximizing Your ADT System
If you’re new to ADT or want to get more out of your system, it’s helpful to explore accessories or compatible devices. While ADT services must be purchased through ADT directly, online marketplaces like Amazon are great for:
- Extra door or window sensors
- Key fobs for quick arming and disarming
- Replacement keypads
- Third-party smart home devices that integrate with ADT systems
- Reviews from other users who have the same equipment
Upgrading your system with the right accessories can significantly increase your home’s safety and convenience.
