Hello everyone,

I have a but of a problem with a kentec syncro running hochiki loop sounders.With ever increasing regularity I am getting sounder disconnected faults from loop base sounders,sometimes if I unplug them and refit them the panel will clear and never show them again,for others they are permanant.It is a fairly new system so its unlikely they have all gone faulty already,but its never to soon I guess.The kentec syncro sees them if I power down th eloop and let it relearn for 20 minutes but then it quickly misses them again.Any ideas would be much appreciated.

Are you using YBO bases or the older CHQ-Bs......??

Have you spoken to Kevin at Kentec Technical.....??

Too obvious maybe, but water in a sensor or sounder anywhere on the loop can cause spurious fault messages ("sounder internal fault" is another).

Are you using the YBOs as stand alone sounders or behind detectors?

Have you tried swapping the bases to see if the fault follows the base ?

We've had a few problems with "internal faults" on CHQ-Bs but but not on YBOs....

Well thanks for your help, Im assuming they are faulty now, put them in a programmer, it couldnt see them so i guess they have failed. theyare mounted behind the smoke detctors,Have ordered some replacements so I will hope that works.

thanks all

Quite a few engineers having similiar issues with new Hochiki kit, had to flash an Advanced panel before new loop beacons would work. Ask tech for a flash upgrade for panel

have you tried testing it by the panel , it could be a wiring issue
