I recently had the same problem with a Safe-T-Alert detector. Mine was showing a malfunction alarm when the supply voltage dropped to ~11.5 volts. I called the manufacturer (MTI Industries) and was told that they had reports of this problem. The detector was only a few months old and still under warranty. MTI sent out a replacement unit and when I received it, I sent the defective one back to them. I tested the replacement on a power supply down to 9 VDC, and it didn't show a malfunction alarm.
I should probably also mention, that when I had the malfunction alarm on the detector, the battery voltage was at ~11.9. I was load testing the battery, and had almost everything that ran on 12 volts turned on in the trailer.
That sounds like my problem only with slightly different voltages. Unfortunately, I've tried several different units and still have the problem. In my opinion, I can't trust Safe-T-Alert anymore. They won't resolve the issue and the device is too important to rely on their product. Thanks for backing me up. I thought I was the only one having problems.
