Frequently Asked Questions

Q: Why choose cellular over Wi-Fi for connected alarms?

A: Cellular alarms work in basements, stairwells and remote units where Wi-Fi is weak or absent, and they need no consumer pairing - installers deploy them like standard alarms.

Q: How long does the battery last?

A: Design life is multiple years with scheduled reporting; the platform alerts when a unit's battery is low, so maintenance is targeted rather than scheduled.

Q: Can the monitoring platform be white-labeled?

A: Yes. Dashboard re-skinning with your brand and tenant-facing notification flows are standard OEM services.

Q: What happens during a network outage?

A: Local detection and the 85dB alarm still work; events queue and sync to the cloud when connectivity returns.

Q: Which certifications apply?

A: Detector function carries the applicable standard (EN 14604 on EU models); radio modules hold their own CE/RED compliance, with documentation per model.
