Earlier tonight I was at a restaurant that appears to have an addressable Fire-Lite system (judging by the annunciator) and the usual Spectralert Advances and BG-12LX’s. When we were getting ready to leave, I noticed that a smoke detector near our table had both LED’s illuminated red. They stayed steady with some slight flickering for about 20 seconds before returning to the normal polling flashing. There was no smoke or steam around and it wasn’t near the kitchen. It caught me off guard seeing a detector that appeared to be in alarm, and although nothing happened, I was curious why this may have occurred. Is this how a detector appears when going through an alarm verification process, or would it have been something else?
Sometimes Fire-Lite/Notifier addressable equipment does that. It’s just kind of a hiccup. Maybe it has to do with self diagnostics, but I’ve noticed that once in quite a while, the detectors will do that. It seems to be normal.
I’ve seen the same thing happen with detectors on my 7100, but only for a few seconds. Seems to just be a quirk of the System Sensor SLC protocol.
Was it going through Alarm Verification?
[EDIT] It was going through Alarm Verification mode.
Do you know what brand the system was? Because I know that some of the Honeywell brands that use the System Sensor devices have a self-test cycle that occurs every so often where the detector’s LEDs do flicker rapidly for a few seconds.
The system is Fire-Lite. All the pulls were addressable Fire-Lite BG-12LX’s, signals were Spectralert Advances, and the smoke detectors looked similiar to the Notifier model shown here: http://www.fire-chief.com/images/fsp-851.jpg
The restaurant was built and opened several years ago. My dad says he saw the panel in the restrooms hallway, and says it had the normal “System all Normal” message along with the name of the restaurant and address, then below it “AC Power” was illuminated in green. This seems like a Fire-Lite Ms-9050UD to me, but I can’t be sure without seeing it myself.
Yeah that’s an MS-9050UD.
