DHD Fire alarm will not stop. Smoke detectors going off

The  SLX-AD-T3 firefighter sensor that we have installed is designed to be a helpful listener, not a smoke detector itself. It works by picking up the alarms from your existing smoke detectors, which were installed by an electrician following standard electrical codes.

Here's some information about how our sensor and system work:

• The firefighter sensor listens for existing smoke detector alarms. It doesn't have its own smoke detection abilities.
• If a malfunction on the standard smoke detectors triggers their alarm, it's not a DHD system issue, but an electrical system smoke detector issue. Unfortunately DHD can't troubleshoot electrical system issues.
• This likely means a malfunction with the smoke detectors themselves. The firefighter sensor is working correctly by responding to their alarm, which does trigger our alarm, as designed. 

In short, the firefighter sensor is a messenger, relaying what the smoke detectors are saying. If the smoke detectors are going off due to an electrical issue, the firefighter sensor is functioning as designed. The malfunction is with the electrical smoke detectors themselves and would need to be addressed with the builder or electrician.
