Have a Silent Knight technician come in and reprogram it so the HVAC shuts down when he pulls it.
Tough to say without knowing more about the HVAC system in those buildings, but the fire alarm isn’t always required to shut the units off. Some only get shut off when smoke is detected by a duct detector at the unit, and if a unit is under 2,000CFM it isn’t touched by the fire alarm at all. In other cases, when there’s a smoke control system, then they are selectively shut off or turned on.
Magnetic door holders are pretty much always programmed to drop when the NAC’s go off. Those door holders take power to keep active, when the system switches to activate the NAC’s, they don’t want to be wasting power on door holders. Not to mention in a general alarm those doors need to be shut anyways for either smoke control purposes or to retain the fire rating on the fire wall they’re apart of.
The system should also unlock any exits on alarm, if there’s an access control system keeping any locked.
Where I live, you actually have to use some kind of door holder that lets the door close when the fire system goes into alarm. In other words, no manual door holders. My friend’s church (where scouts is) had the door holders on the bottom of the doors removed by the fire marshal because they “supported the spread of a fire”. Not actually sure if my local AHJ actually has this code, but it looks like it’s enforced.
I don’t want to bother my dad by dogging on him for fixing the system; it’s pretty old anyway. It’ll most likely be replaced by a 5820XL soon.
But hey, if that happens, I’ll gladly take the old IFP-1000 off their hands! :mrgreen:
I noticed that last time I was there there was an old ADT Unimode cabinet next to the IFP-1000, probably the system’s former control panel. It looked like it had the power supply and batteries in it, as well as the manuals. It was a fairly big cabinet, so maybe it was ADT’s knock-off of a 2001? The school was built in the 70s and I do remember seeing a 6" bell, though, that was probably a class-change bell before they got a Dukane PA system. Is anyone familiar with older Unimode systems and what devices they would use?
Edit: “pretty old” meaning the 90s.
Did the Unimode look like this? (from 1974)
While on the subject of 2001 knockoffs, I think Destin said that the KDR-1000 was one of the first. (Destin’s image)
It didn’t quite look like that, but it looked a little similar. It had three (plexi)glas(s) windows so I assume it had three bays. I’ll see if I can get my dad to snap a picture of it. The “Unimode System” logo was on the right side, by the lock, IIRC.
The Big Green, (Aka the Av-32 man) I think the 2001 was a bit smaller that that! :lol:
Hey, watch it! :lol:
I was born in 99 so don’t be talking that we are old.
99? That’s barely '90s 
I’m 18 years old, born in '96, and I feel old! Think about it, people born in 1990 are about 24 years old.
The 2001 was a modular system, available in different cabinet sizes for different applications.
The 2001 that Andrew has (and the 2001 that Destin had) were single-bay, small cabinet models. Depending on the cards installed you could have a varying number of zones. Larger buildings would have around four to six bays, with like 32 zones and voice evac capabilities. It all depended on what building the system was going to be installed in.
Back in the 11-12 school year, on May 10, 2012, we had a regular fire drill.
Ironically, the fire alarm went off AGAIN two days later at about 7:10 AM two says later. People were still eating breakfast in the cafeteria when the alarms (Wheelock NS code 3 inside, Wheelock AS code 3 outside) and we waited outside for precisely 42 minutes.
It turns out the panel was malfunctioning or in System Trouble.
Rumor was going around that one of the lunch
ladies accidentally activated the heat detectors.
I also recall a time in the 12-13 year when I was explaining to my friend how our school should’ve bought wireless mice rather than wired for the iMacs when the fire alarm went off.
Same school. Wheelock NS doing code 3 inside, and AS outside code 3.
Not really on topic, but why wireless mice?
They cost more, and have higher maintenance costs (compared to wired being 0).
Not to mention that they’re more fragile.
Sure, I like a wireless mouse, but a school would be better off with wired.
lol
11/10/14: 7th Period.
I was in one of the portables waiting for the teacher to finish his introduction and start the lesson, then the alarms sound. There’s a ZNS-MCC-FW in the room along with a newer Siemens FirePrint detector (as opposed to the older FireSmart ones in the rest of the school), and newer HMS-D pull stations.
Interestingly, the “Push Here Then” piece goes in a lot easier than the older model. (I didn’t pull it! :lol: )
There’s also an AHWP on each building, and they face each other. It’s quieter in the classroom than it is on the ramp!
Sure it’s a ZNS-MCC-FW?
Siemens rebrands Coopers NAC’s with slightly different part #'s and a different sync protocal.
Well, it’s Siemens’ equivalent of the ZNS-MCC-FW. I don’t have that model number off the top of my head.
Anyway, today we had a Veteran’s Day assembly at one of the elementary schools. My school’s band was there, and right after we played the national anthem, the fire alarms went off! It was an EST3 system with SIGA-PSs, SIGA-278s, and white Mega Drives. :lol: The outdoor signals were weatherproof Integrity horns.

I only ask because it’s pretty common to see wheelock branded NAC’s on a Siemens system as well. You can’t mix the devices, but some have all wheelock or all siemens rebranded wheelock.
Yeah, I guess you’re right.
