Simplex 4004 Program Zone as supervisory?

Fire Alarm Help
1

I have a Simplex 4004 Conventional FACP with a 4 zone expander, with a total of 6 zones. The first two are water flow, and I have programmed the other 4 as Fire/Supervisory with using only a 4.7k ohm, or 3.3k ohm resistor.

The supervisory zone shows normal, but when shorted with a valve tamper, or low/hi air switch activation, the FACP goes into full alarm, and not supervisory condition as it should?

I suspect it has to do with an additional resistor configuration requirement, but does anyone else have the expanded manual or detail on this?

Thanks,
Paul

If it’s programmed as fire/supervisory it is likely designed one of two ways:

  1. you wire a resistor in series with the waterflow switch.
  2. you wire the waterflow switch as normally closed with the EOLR in series so it opens the zone.

I’m not fully sure how the 4004 works but there is a member on here who does, I sent him the link to this topic.

Here is the field wiring diagram for WF/SUPV.

That’s exactly what it was.

Having the 6.8k e.o.l. at the end and across the last supervisory switch, and the 530ohm resistor in series before the first supervisory switch as shown in the 841-992 diagram. In my case zones 1 & 2 are dry sprinkler water flow, and zones 3 through 5 are Low/Hi Air, and Valve supervision, and zone 6 alarm, with one pull and one smoke for panel protection. I was looking all over for that 992 diagram!

My manual shows a lot, but not that detail, as the 841-992 field wiring diagram does.

This resistor set-up was very much like a version that you did not see much of, at least in the Louisville Ky area, was a single zone card on the Simplex Black 2001 FACP’s that the card did both initiating and indicating. That is it had horn/strobes and heats, and pulls on the same circuit. The e.o.l. might have been a 6.8k, and the 530ohm resistor had to be in series with the initiating device, but parallel with the circuit, and the same with the horn/strobe, which was usually a Wheelock 7002T.

But that did the trick on our 4004, and allowed me to wrap up an odd job in our surplus warehouse.
Thank you very much,
