Very helpful thank you.

[@bukast1]

thanks for your teaching but i want to know which type of resistance need for the last end

[@2zzjosh267]

What resistor value it must be for the EOL relay ?

[@javcala545]

you are fucking amazing! I coulnt find a good book for this stuff. I really need it to get a job now. Thanks

How do these panels identify which smoke head is alarming.

[@forhizglory]

Is it possible the reason you need a resettable power supply is that the smoke detector used a latching relay if some type. This once it latches you have to actually drive it with a reverse voltage or the latch is reset by re applying power?

My panel won't reset after being silenced. I reset all the pulls but it didn't work. Help?

[@N617A]

so you open the pull stations, silence it then hit reset? that should be enough to shut them off. if not you might have a smoke detector on the fritz or the panel is having trouble reading the resistor.
