FAQ’s on Sync-It™ (NFC technology)

Where can I get help within the app?

You can find help relative to the page you are stuck on within the app by tapping the (?) button.

I’m trying to log into the app and I’m being told I already have an account?

Our new app uses the same backend platform as FireAngel’s web based Installer Wizard. You can log in using the existing username and password you previously registered with. If you are still experiencing difficulties logging in, please contact our Customer Support team.

Where do I need to place the phone over the alarm for successful NFC data extraction?

Hold your phone against the NFC device, move phone until it vibrates and hold still for 5 seconds until test is complete. Please do not move your phone once connected and until test is complete. If moved too soon, connection will be lost and you may need to repeat the process again.

What does device unique ID error mean?

This means the device cannot be added to an account on the app. Options to extract device diagnostics data, run test and also create a maintenance and compliance report are still available.

What FireAngel products can I extract data from using Sync-It™ (NFC) technology?

Currently, data extraction through Sync-It™ (NFC technology) is only available with FireAngel’s FA3328-EUT Temperature and Humidity Sensor with CO alarm.

How do I know which Sync-It™ (NFC technology) test to run?

If you need to assess compliance, review detailed diagnostics, or generate a full record for reporting, the Full Maintenance & Compliance Report is the most appropriate option. It provides a comprehensive overview, including device and environmental data, and can be exported as a PDF or shared via email.

If you require key diagnostic data quickly without additional maintenance questions, the Quick Report offers a faster snapshot of device and environmental performance, also available for export.

If you simply need to confirm a device is functioning correctly in the moment, the Product Test provides a quick, in-app check of core performance within seconds.

Where can I download the FireAngel Installer app?

Sync-It™ (NFC technology) data extraction is available to download via Play Store on Android phones and iOS App Store on iPhones.

How do I check if my mobile phone has NFC capability?

If your phone is set up for contactless payments you will have NFC functionality. iPhone 7 and above have built-in NFC chips and NFC capability is automatically enabled. Most new Android phones also have an NFC chip which will need to be activated. Find ‘NFC’ in your phone setting, toggle to activate and follow the steps outlined for your mobile device.
