How Do I Change the Smoke Detector Siren on the IQ5 NS?

To change the PowerG Smoke Detector Siren setting on the IQ5 NS, open the IQ Installer app, go to Installation, Sirens and Alarms, then find PowerG Smoke Detector Siren. Choose Fire Alarms Only or All Alarms to set exactly when smoke detectors actually sound off entirely right away.

What This Setting Controls

The IQ5 NS (available in AT&T LTE and Verizon LTE) lets you decide whether enrolled PowerG smoke detectors sound only during actual fire events, or during any alarm event on the system. With the default Fire Alarms Only setting, a smoke detector's built-in siren only activates when that specific detector senses smoke or heat. With All Alarms selected instead, every enrolled PowerG smoke detector acts as an additional wireless siren, sounding during burglary alarms, panic alarms, or any other alarm event, not just fire.

This effectively lets you turn your smoke detectors into extra siren coverage throughout the house. Since the IQ5 NS panel itself has no built-in siren speaker of its own, relying on distributed devices like smoke detectors and any dedicated siren accessories matters even more here for making sure an alarm event is heard clearly throughout your security system.

How to Change the PowerG Smoke Detector Siren Setting

1. Open the IQ Installer app. This is the mobile app used to configure the IQ5 NS, since the panel has no display of its own.

2. Connect to the panel. The app communicates with the IQ5 NS over Bluetooth or Wi-Fi to load its configuration menus.

3. Enter the Installer Code when prompted. The default Installer Code is 1111, though your account admin may have changed it to something else, like 2222.

4. Touch Installation. This opens the Installation menu, which lists Devices, Installer Settings, System Logs, Sirens and Alarms, Security and Arming, and Camera Settings.

5. Touch Sirens and Alarms. This opens the list of siren and panic-related settings, including Police Panic, Fire Panic, Auxiliary Panic, and PowerG Smoke Detector Siren.

6. Find PowerG Smoke Detector Siren in the list. This setting defaults to Fire Alarms Only.

7. Choose Fire Alarms Only or All Alarms. Fire Alarms Only means smoke detectors sound only during fire events. All Alarms means they sound during any alarm event on the system.

Why You Might Switch to All Alarms

Larger homes or homes with distant bedrooms are the most common reason to switch this setting. If a burglary alarm triggers while everyone is asleep upstairs and the nearest paired keypad is downstairs, that alone might not be enough to wake someone. Since smoke detectors are typically spread throughout a home, including bedrooms and hallways, setting them to All Alarms turns every one of them into a local siren, dramatically improving how quickly a household notices any alarm event, not just fire.

Why the Default Might Be Right for You Instead

Fire Alarms Only keeps the alarm sound specific to the event type, which some households prefer since a smoke detector sounding usually means something more urgent than a general burglary alarm. If your system already has enough siren coverage throughout your home from other devices, there may be little practical benefit to enabling All Alarms, and keeping smoke detectors dedicated to fire events avoids any confusion about what kind of alarm is actually happening when you hear one going off.

If the Setting Doesn't Seem to Apply

This setting only affects PowerG smoke detectors that are actually enrolled on your system, so confirm you have at least one added before expecting to hear a difference. If you change to All Alarms and don't notice detectors sounding during a test alarm, confirm the change actually saved in the app before backing out of Sirens and Alarms, and remember that monitoring test mode may suppress audible sirens during certain test procedures, which could explain why a test doesn't sound the way a real alarm would.

This Applies to Every Enrolled Smoke Detector at Once

This is a single, system-wide toggle rather than something configured per individual smoke detector, so switching to All Alarms applies to every PowerG smoke detector enrolled on your system simultaneously. If you have detectors spread across multiple floors or in several bedrooms, you don't need to configure each one separately in the app, they'll all switch behavior together the moment you change this one setting. This also means you can't currently set some detectors to Fire Alarms Only while others are set to All Alarms, since the setting applies uniformly across your entire installation rather than per device.

Changing the PowerG Smoke Detector Siren setting on the IQ5 NS lets you decide whether your smoke detectors serve as extra sirens for every alarm type on the IQ5 NS.
