I have to build a control box that shuts down (7) AH's... connected to the NC contacts of a Fire Alarm..

My plan is to use (4) Altronix RB5- 24 relays controlling (7) of these..

Anyone know a easier way....

Why do you need a RIB? Just interrupt the 24 volts and be done with it.

I want to have separate controls by the panel for each AH relay...

I guess I'm not following what you're trying to do then. It seems to me that Altronix relay would do the job without using another relay.

A fire system interface?

The AH are line voltage.. RIB's are made for that..

I like the idea of having LED's showing the AH is disconnected during a FA test..

Stop killing the line voltage, do it right and kill the control circuit.

That's like asking him to load his truck with electrical tools and material. Being an electrician just isn't in his forte.

We have been though this already.. some AH keep running when you kill the control voltage...

I think it's just plain wrong for people's lives to depend on B4T's jury-rigging.

Go sit in the corner and pull your pork.. you seem stressed out..

Bullchit.



You just can't figure out how they are wired.

Even a loud mouth asshole like you can be wrong.. :no::no:

I went directly to the CT and the unit still kept running..

Some units keep running to dissipate the heat after the stat has reached temperature..

Yes that is most of them.

Which proves you don't know what you are doing.

CT supplies power to RED of stat.. this is how small units are wired,,

Breaking the RED does nothing.. it USED to work just fine.....

You're still a loud mouth asshole.. :thumbsup:

It is a small unit, yet you cannot figure out what controls the fan.

I think that says a lot ....

That was the first thing I tried you moron.. it did nothing.. stop being a jerk.. :no::no:

 

[wildleg]

a lot of commercial units made this century have a built in set of terminals for that specific purpose. you checked the literature, didn't you ? (not trying to be a smart a$$) (you could also just buy a 7 pole contactor)

An electrician could answer that if they had looked at the unit.
