I am reading through the cut sheet for a Simplex 4007-9101 FACP and I am confused about maximum current ratings. One area says there is a maximum of 6A output current for: special application notification appliances. then it says there are 4 NAC circuits rated 3A ea or 2A for regulated 24 VDC. the V/O and V/A alarms I have looked at show they operate on 29Vrms (which is generaly an AC term) so i guess my question is… do I have 2 or 3 Amperes per circuit, and is that only up to 6A total or do I have the full 8, or 12.
let me know if you need additional info, i can scan the document I am looking for and highlight the areas I am looking in.
I looked up the datasheet on the 4007ES. The power supply is capable of 6 amps if using special application notification appliances. These are devices that are UL listed to be used with the stated panel in the per circuit quantities listed in the instructions. The notification appliance electrical characteristics are known and are matched to the panel.
The Regulated 24 ratings are for “other” notification appliances. This reduced rating allows for such things as an unknown turn on surge current by the appliance. In field experience I have measured devices that draw less than 1 amp steady state but have a 9 amp turn on surge measured using a Fluke 87 meter on the 1 ms min/max function.
The 4007ES NAC ratings have to be added together for 6 amps total. In other words, 4 circuits at 1.5 amps, or 2 circuits at 2 amps each and 2 circuits at 1 amp each, or one 3 amp circuit and 3 circuits at 1 amp each.
I would need to see the notification appliance datasheets you are looking at. The only ones I have seen that use the 29 VRMS term are the addressable devices for IDNAC. The 4007 does not have IDNAC. What is the datasheet number you have.
The 29 VRMS rating is applicable because the IDNAC is a combination of steady DC with communication riding on top of it. The communication creates an AC component to the voltage.
Thank you for the reply, the data sheets I was looking at were addressable units, but I don’t see any need for addressable notification devices so I am going to need to look into other types. (not to mention the fact that you just advised me they will not work anyways)
V/A was: model # 49AV-WRF
V/O was: model # 49VO-WRF
the current usage with max candelas settings were .215A and .208A respectively. I already knew I was going to need a NAC extender, but I’m working on drawings and location right now and trying to figure out a wiring scheme that will be within the current capabilities of this panel.
Update: You specifically asked about the 4007-9101 panel NACs. I found that the 4007-9201 does have the IDNAC for ES addressable notification appliances.
I dont know if it comes with experience or what but i find these data sheets to be very vague and difficult to interpret. does this come stock on the panel or is it an additional module? if it is stock that means i will need TrueAlert Notification appliances or can it run them as a conventional notification appliance since it is a “Hybrid”
Datasheets highlight key features and spell out a few specific things consultants/engineers are looking for, all in a few pages, so vague is kind of the name of the game.
You need to find the installation manuals to really get a good idea of what something can or can’t do.
I have done numerous Google searches to locate installation manuals, they do not seem to exist for this panel, at least not openly and free for the taking. I have found a manual an used it as a rough “go by”
I personally wish that a different manufacturer was involved, Simplex (not trying to vendor bash) seems to like to keep their information as secret as possible which is making it extremely difficult for me to learn about these systems.
They do everything in house so they have no reason to release any information to the general public. Everything is supposed to be done by a trained Simplex tech or designer, they don’t sell widgets to end users but instead they sell, maintain, and service the entire system.
