Daily Fire Alarm Question!

If you look closely at the scope photo I posted the peaks of the half sine wave are flattened. That probably is due to the MOVs and other components in the power supply and across the NAC. It is possible that the flattened sine wave changes the sound of a mechanical horn. The clipped peaks make the sine wave seem more like DC. With every half cycle going to 0 volts it is obvious there is no filtering in the circuit.

Since nobody answered the 4100+ question, it is a 1,000 point panel. If the panel is part of a network the point total combines local hardware points and network external points. A 4100+ also can provide 2,000 annunciation points. That would be LEDs and switches.

4100ES, 4010ES.

I’ve got one…

How many wall-mounted visual notification appliances are required in a space that is 40x40 feet, and what intensity must the strobe be?

The reason it takes that one only 3 seconds is because when they are in trouble, they don’t reset. I also said on a normal reset. Other people I know who have 9050UDs or NFW-50’s (Notifier equivalent) say that they take around a minute and a half to reset normally. I have an NFW-50 and that’s how long it takes for me every time, regardless of the size of system.

My question: What year did voice evac start to become more prominent over using horns and bells?

Q= what key dose a GE FIREWORX FG-3 use, Thanks! :smiley:

I think it uses the EST key.

Voice evac was introduced in the early 1970’s and probably was mandated in high-rises (I think it’s 7 floors or more?) shortly after that.

And that’s the CAT-45 key.

Q: what candela rating was not used in the simplex 4903 TrueAlert series notification appliances?

Nobody answered this question yet.

I believe the correct candela is 15cd (if I’m not mistaken) and the # of strobes required is 2. For the record, I used this as a source: http://www.cfaa.ca/files/flash/MEMBERSHIP/Fire_Alarm_Data_from_CHUBB_Edwards/Strobe_Application_Guide.pdf

What does the Braille text on the Fire-Lite BG-12 say exactly? (You can find a diagram with the Braille text in the pull station’s manual.)
