yeah :slight_smile:
Thanks for helping!

122

No prob!! My school has a class called pltw. Helping you with this will allow me to work on teamwork! :smiley: :smiley:
PM me any details you can currently think of to me! :smiley:

123

OK
I’ll think of some features that I want in the panel.

124

That sound great! :smiley:

125

Does anybody know how a relay based trouble circuit works? What about supervisory? I am planning on adding these in to the panel after it’s done.

126

Crud…I know this but cant remember… :frowning:

127

This is what I have so far with the 2450 panel, which will have trouble and supervisory circuits.

128

hmmm… :?

129

NewAgeServer? Do you know how to make a relay based trouble and supervisory circuit?

130

I haven’t figured out a way yet. I am thinking of some ideas involving transistor logic but I haven’t tested any.

131

Question: If I were to hook up a resistor, would it draw enough to trip my relay? The relay is 2880 ohms. If I were to also put a smaller ohmerage relay that WOULD trip with a resistor, would that be how I could do trouble and supervisory? I’m basically asking if the resistor needs to have 2880 ohms to trip my alarm relay.

132

Please explain more

133

If I were to hook up an EOL resistor with less ohms than my alarm relay, but more than a trouble relay, would it trip the trouble relay and not the alarm relay?

134

Stupid me! I wired the first relay wrong. Dumb circuitlab made me think that the relay contacts were across from each other, like the coil hookups are. But it turns out that they’re next to eachother. So I was shorting out the + and - making it buzz. Wired the new one right, and it works!!! :smiley:

135

Here’s a video of the panel working.
(Still uploading as of 8PM)

136

Nice :smiley: :smiley:

137

Would a System Sensor 2424TH burn up on switched power? Just wondering before I hook it up.

138

I dont know :?

139

Switch-mode power supply power?
As long as it is not full wave rectified (I watched your video, it is not) and the smoke is 4 wire then you will be fine.

BTW, what is doing the signal coding? Some sort of timer module you bought?

140

Yeah, It’s a coder module for LEDs hooked up to NAC 1. It does continuous, fast march, slow march, and other unusual codes.
