Fire Alarm NAC test

[Gb755c]

I don't understand how that can be a thorough test since the alarms are only sounding for about a minute that is a three story building no way anyone could check them all that fast. 

[NLind]

@Gb755c I always thought the same thing. But maybe our local AHJ (Authority Having Jurisdiction) doesn't require a full NAC walkthrough… who knows.

[paul9511]

what's "NAC" ?

[NLind]

@paul9511 Notification Appliance Circuit.

[Gb755c]

How often are NAC tests done there?

[NLind]

@Gb755c Once a year (official inspection)

[phillies4100]

why is this code 3 i thought it was continuous during the real fire?

[Gb755c]

@phillies4100 The original Zans 400 motherboard was either set to continuous or the panel was set to interrrupted meaning the panel isn't doing the coding and it's whatever the jumpers on the wheelocks are set to. Most likely since it's doing Code 3 the SK 5208 is probably set to code 3 and the jumpers on the horns were either set to accept the panel's code or were set that way already

[pivotous]

hey,NLind, you getting a panel at all?

[NLind]

Sometime I'd like a 4002/5208 maybe...

[RJARRRPCGP]

That Stopper sounds like the ones at Crotched Mountain school. (Greenfield, NH)

[NewAgeServer]

Is that a Silent Knight 5208? Sounds like it.

[NLind]

Correct! It's the 5208's mobo (Motherboard) in the cabinet of our old system, a Gamewell Zans400 I actually have the 5208's cabinet. When they upgraded it, the tech let me keep the cabinet.

[FireAlarmKid]

What panel is used in this system?

[coolkid2676]

5208

[eddieeddieeddie13]

Are the MIZ's in code-3 too?

[willbill808]

Yes, because they are coded by the panel.

[eddieeddieeddie13]

Cool.

[danll5]

Are they loud?

[NLind]

They're MTs set to Continuous, but the panel is now set to do Code-3 Temporal. Also there are LSM strobes (the one seen.)

[mallmaven]

Were You Able to Here the MIZs? or did he just set of that zone?

[NLind]

Since I stayed in that area and they only tested them that once, I only heard the MTs.

[markfmark1988]

on a panel i think if u press all zones button it activates a fire drill

[willbill808]

I thought the Wheelock MTs had a delay, so it would do short little blasts in code 3, not full blasts like this.

[DVaccarelli1988]

...and that's why the strobes were flashing temporally instead of steadily.

[Trainman11185]

i think it looks like a wheelock mt

[Dabura7]

even someone tested a strobe witch went on for 123 minutes

[brownguyrav2007]

what does NAC mean?

[danll5]

NAC (notification applience circuit) is were the FACP gives the power to the alarm.

[brownguyrav2007]

OOOOHHHH, in the UK they are called sounder circuits!

[danll5]

Cool

[eddieeddieeddie13]

In your "Real Fire Alarm video" the alarm was in continuous.

[mallmaven60]

That's the MT-24WM

[Federal3t22]

I believe those are MT-24-LSMs.

[mallmaven60]

Look carefully at the strobe

[mallmaven60]

They even looked like WM's in the Real Fire VID

[mallmaven60]

Unless they are wheelock EH-ELI-WM's?Something with a 117c

[NLind]

Correct. All of the NAs in the building have LSM strobes (15/75 cd)

[SilentXKnight5204]

Cool! I love the sound of MT's!

[NewAgeServer]

Well then you must love the sound of AS's too. ;)
