Weird electrical issue - anyone have experience?

Helping my mom pass inspection so she can move into her new house.

Fire alarms aren't all going off at the same time...

Well, let's call them A, B, and C.

When you test A - all of them sound.
When you test B - B and C sound.
When you test C - only C makes sound.

Is this just a matter of how we wired them? All on the same circuit I believe, but not understanding the communication issue between them.

Odd place to bring this up, I realize - but I don't have many other places to go, and the nearest electrician is likely a hundred miles away so if it's simple and is just wiring them differently I can do that.

yep, I would say they are definitely wired wrong,i`m no expert but I do know there are series circuits and parallel circuits and it sound s like the alarms are wired the wrong way.maybe they are wired in a series when they should be wired in a parallel,or maybe they are wired in a parallel when they should be wired in a series.

I would think finding the correct schismatics online wouldn't be hard .

Yep, wired wrong.

I deal with fire systems all the time.

Kind of wondering what kind of system she has because most residential in the US are battery operated and independent of each other.

Sounds like one that is hard wired to emergency services . The stand alone battery types don't usually send a signal other then the scream .

Black and white need to be hooked up properly, as well as red/orange

The red/orange wires need to be all connected to each other on one circuit, it will notify the alarm system


I don't think this matters for inspection purposes as long as each one works when pressed, the communication to alarm unit isn't required, but good for safety obviously.

I would check all the wire nut connections, particularly the red one, pull them apart and make sure they are twisted onto bare wire properly.

These have batteries, and are on electricity at the same time.

Independent of each other is what I'm used to, but the code inspector seems to expect them to all go off together

This helped me find a website that makes sense of it
communication between alarms

I'll have to check that the red wires are wired correctly

Let's start with what system have you installed?

I agree with Tardacus. Wiring/sequential order...easily rectified. Series and/or parallel mixed up....

Because there was reports of DHS hacking and there are other dot's that need to be connected I feel this new YT vid puts together some really important facts into one YT clip . The Awans had access to DHS and this might be why DWS threatened the Police chief ...The short first part is interesting while the main body is a politician on Cspan
