How Do I Change the SIA Limits Setting on the IQ5 NS System?

To change the SIA Limits setting on the IQ5 NS, open the IQ Installer app and then navigate to the Installer Settings, then toggle the SIA Limits, which is enabled by default to hold all the delays to compliant ranges. Because the panel has no screen of its own, this is all done in the app.

What SIA Limits Does

SIA Limits on the IQ5 NS (available in AT&T LTE and Verizon LTE) applies the Security Industry Association's false-alarm-reduction standards to your timing settings. When it is enabled, which is the default, the panel holds your entry, exit, and dialer delays within SIA-approved ranges, which keeps the delays long enough to cut down on accidental alarms before you can disarm. Keeping it on is the recommended, compliant choice for most systems, since it is designed to reduce false dispatches on your security system.

Turning SIA Limits off unlocks much shorter minimum delays for custom or specialized setups. Here is how the ranges change:

So the main effect of turning SIA Limits off is that you can set much shorter minimums, like a 5-second entry delay or a 0-second dialer delay, which the SIA-compliant ranges would not allow.

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. For most installations you should leave SIA Limits enabled, since it is the standard false-alarm-reduction setup, and only disable it if you have a specific reason to use delays shorter than the compliant minimums.

Change the SIA Limits Setting

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 SIA Limits setting.
   
   Navigate to Installer Settings and find SIA Limits.
3. Toggle SIA Limits. Leave SIA Limits enabled to keep the compliant delay ranges, or disable it to unlock the shorter minimums shown above. Your entry, exit, and dialer delay options update to match the choice.
   
   Leave SIA Limits on, or turn it off.

Tips

SIA Limits exists to reduce false alarms, so unless you have a specific need, leaving it enabled is the safe choice and keeps you within industry guidelines. If you turn it off to set a very short delay, keep in mind a shorter entry delay gives you less time to disarm before the alarm sounds, and a shorter dialer delay gives you less time to cancel a signal before it reaches the central station. Certain certifications, such as UL, ULC, and EN Grade 2, also require specific delay values, so check those requirements if your system must be listed.

Changing the SIA Limits setting on the IQ5 NS controls whether your delays stay within the compliant false-alarm-reduction ranges.
