How Do I Change the Global Input Mode on the IQ5 NS System?

To change the Global Input Mode on the IQ5 NS, open the IQ Installer app and then navigate to the Installer Settings, then set the Global Input Mode to Normally Closed, End of Line, or Double End of Line for your zones. Because the panel has no screen of its own, this is all done in the app.

About the Global Input Mode

The Global Input Mode on the IQ5 NS (available in AT&T LTE and Verizon LTE) sets the end-of-line supervision type used by every hardwired zone whose own Input Mode is set to Global. In other words, it is the master wiring style those zones follow, so you can set the supervision once instead of configuring each zone individually. It applies to hardwired zones brought in through a wired-to-wireless converter or hardwire expander on your security system.

There are three choices. Normally Closed uses no resistor and simply watches for the loop to open. End of Line, the default, uses a single end-of-line resistor so the panel can tell a normal open from a cut or shorted wire. Double End of Line uses two resistors to distinguish an alarm from a tamper or fault on the same loop, which is the most supervised option. Your choice should match how the zones are physically wired.

Before You Begin

Because the IQ5 NS has no screen, its Installer Settings are reached through the IQ Installer app. If you have not yet connected the IQ Installer app to your panel, see our guide on setting up the IQ5 NS with the IQ Installer app before proceeding. This setting only affects hardwired zones that have their Input Mode set to Global, so zones set to a specific mode of their own are not changed by it. Make sure your resistor wiring matches the mode you pick.

Change the Global Input Mode

1. Open the IQ Installer app. Open the IQ Installer app on your mobile device and make sure it is connected to your IQ5 NS.
   
   Open the IQ Installer app connected to your IQ5 NS.
2. Navigate to Installer Settings. In the app, go to the Installer Settings and find the Global Input Mode setting.
   
   Navigate to Installer Settings and find Global Input Mode.
3. Choose the input mode. Select Global Input Mode, then choose Normally Closed, End of Line, or Double End of Line. The mode you pick applies to every hardwired zone set to Global, so confirm it matches your wiring.
   
   Choose Normally Closed, End of Line, or Double End of Line.

Tips

Match the Global Input Mode to the resistors actually installed on your zones, since a mismatch can cause false troubles or keep a zone from tripping correctly. End of Line is the standard choice and the default for most installs, while Double End of Line is used when you want the panel to distinguish an alarm from a tamper on the same two wires. If only some of your hardwired zones should use this setting, leave those on Global and set any exceptions to their own input mode individually.

Changing the Global Input Mode on the IQ5 NS sets the supervision style for your Global hardwired zones in one place.
