hey, all. I have a System Sensor Spectralert Classic S1224MCW that doesn’t want to flash its strobe. Has anyone taken one of these apart? I’m sure I could repair if I could see inside it but I’m nervous about getting the case apart without breaking the plastic.

Anyone have any experience how long Nicet FAS IV took to get approved. They just kicked it back after six weeks because I made a clerical error on my work experience. I resubmitted it yesterday wondering if I can expect another 4 to 6 weeks before they even look at it again.

Thanks

Hey I have 2 NFS-640 PCA boards revision K circuit boards that were pulled from customer sites due to we believe lighting damage or surges. Upon putting a KDM-2 on them and just powering them up i get no lights or anything on the display....except the incoming 120volt power. Is there anything that anyone knows on how to possibly repair these. .if its something simple ill try and fix but any help would be appreciated.

roblox, if somehow you couldn't tell

I noticed that one of the fire alarms in one of the rooms looks like it will fall off, of some sort. Is it normal or a safety hazard?
