National Time And Signal 411 Power Issue

In my system test, I use a relay. I will Skype you and show how it works

In order to drive the 4030 off the 2001 I used a relay card wired to the audible NAC output. A 12 VAC transformer’s power output was fed through that relay and into the 4030 to create an unsupervised AC circuit to power the horn.

Now to be fair, Simplex did actually have an AC NAC card for the 2001 which was able to supervise a circuit with AC signals and sound them in alarm.

As for my rant in my previous post, I was on my phone and did not get to write a full response. ccs46, please learn the terms and what they mean before you attempt to help and provide false information. I’m not going to give a warning though since you made it obvious that you were guessing but it can still be defined as potentially false advice, so please do not do that again.

Transformer: Increases or decreases AC voltage
Rectifier: Converts AC voltage to Full-Wave Rectified DC
Filtering Capacitor: Smooths out Full-Wave Rectified DC to produce “clean” DC
Voltage Regulator: Reduces a higher DC voltage to a lower voltage and maintains that lower voltage
Relay: Allows one power source to switch another. Think of it as a light switch controlled with electricity.

Since this is kind of off topic but in the zone on what we are talking about, I have a FWR question. What was the problem with using Simplex alarms with a panel that gives out FWR? I forgot.Also what was that panel? Lastly, are their any other FWR traps that is important to know on what might damage alarms?

Two words: Isolation transformer.

I honestly did think you were using a ac card because I heard it some where but nvm. I will try my best to provide the best information.

So after achieving the information I needed, I finally got them to work and Ill be making a video of them soon.
