System that came out of an old hotel set for demolition soon. I still have more devices to pull out later as this was day 1. (More BG- 6 and old Fire Lite and System Sensor smokes remain) Consisted of two panels linked together for each wing. The EST panel replaced a Sensiscan 1000.
Pulled out a ton of BG-6s, Fire Lite 7004 horns with some miscellaneous smokes, an annunciatior, EST IO500 and a Miniscan 424
I’ll have better pictures soon!
Dang, excellent haul! Glad you were able to save all those devices from the wrecking ball &/or landfill! (& I hope you save even more for that matter!)
The fact that you say that those devices came from a hotel & the BG-6s reminds me a lot of the Gadsden Hotel in Arizona, the fire alarm system of which was featured prominently in an episode of Hotel Impossible (including the BG-6s it had as its manual pull stations (& may still have today in fact going by photos on Google Maps).
I love this one! In the words of Garrett Claridge, “Very old and, perhaps, vintage.”
The pull stations look fantastic! BG-6s seem to have fragile paint—the ones I see listed online typically display noticeable chipping and flaking. You’re lucky to have found some that have remained in such good condition; they aren’t easy to come by.
The Miniscan 424 panel is a great find. I haven’t seen many photos of those panels. The Miniscan 124, which appears to have been sold alongside the 424, seems to be more common.
Update 11/6 ~
The building across the lot, not adjoining but still apart of the company at the time I have some unfortunate news but still a rewarding haul from this one. This building is still rather big but due to this one having more structural problems I wasn’t allowed in certain areas (for good reason) so that limited my outcome for this haul. Within this system was only one panel being another Miniscan 424, along side the same branded 7004s, BG-6s the same singular outlying Wheelock 7002T, a Wheelock AS (turned out to be dead) and a Faraday 5410 used for general signaling. In that case it was used as a freeze alarm for the boiler room.
Back to that 424 mentioned earlier, that’s where the unfortunate news lies. The panel shows no life aside from toggling a red switch which presents life for a second but also showing a Ground Fault - which connects the dots. If anybody is interested in the second panel you are more than welcome to DM for further details on that.
Neat how you managed to save a good portion of another building’s system: nice job! Shame about the 424, but does the other one at least work? (the one you got initially)
“connects the dots”? How exactly? Is there a ground fault which is somehow preventing the panel from starting up properly?
I’m no expert with FA systems just yet, this whole opportunity to receive these alarms sparked my interest further from what was a mere career path a friend recommended me, as he’s in the industry. I only assumed that was something that had to do with the problem preventing the panel from working. That’s on me for not asking and just assuming. Anyone who could help on that topic would be greatly appreciated!
As far as the other panel goes, yes that one 100% all functions aside from one LED that’s burnt out which is no biggie. The panel was actually still on and in alarm when I was granted access earlier on. Seems like some trespassers at one point had activated it and left it on “Bell Disconnect” for months or even years now. Hence the really bent door where the lock is located.
Oh okay, might be.
Ah okay, nice! Heh, how about that.
Forgot to mention these 4, the first row are pretty common ones, the larger of the two I’m rather unfamiliar with. Can’t find any info regarding the model number SD12. I have one that’s Fire Lite and one that’s ESL.
Yeah: System Sensor 2400-series detectors (possibly 2400s which can supposedly run on both 12 & 24VDC).
Neither can I seemingly, but there’s apparently another model of that detector called the “SD14B” that seems to be much more common: both models are rebranded ESL 1025Cs.
That’s odd…
Sounds good, glad you managed to save nearly everything from those buildings! (& of course best of luck in both refurbishing the one 424 that works fully & putting together that demo board!)
Something I just realized: do you mean “7004” or “7002”? (since the 7004 is the AC version of the 7002, & it seems highly unlikely that a system from that era would have AC signals)
Never knew that’s what the difference was. I thought it was a matter of the horn grill difference between the 7002-7004. Indeed I do mean 7002 then. Thanks for correcting me on that.
Oh okay, sure thing!
Funnily enough the community once thought that 30 & 7000-series models with “T” in their name meant they were closed-grille (the “T” was thought to stand for “tamper-resistant”), but as it turns out the “T” actually stands for “terminal” or “terminal strip”, as such models have terminals instead of wire leads: most closed-grille-model 30 & 7000-series devices just happen to have terminals as Wheelock discontinued wire lead 30 & 7000-series models around the time they redesigned the grille (though terminal strip open-grille versions also exist as such models were supposedly made alongside non-T models) (all of this is going by another member’s research, which I would have never known about myself, so thanks to them for their time & effort spent finding all this out).
Gotcha! Thank you for the info!
Freeze alarm… That’s a direct opposite of a fire alarm
That would technically be a water alarm (which are actually kind of a thing: Northern Tool once sold a standalone water alarm system, & security systems can be outfitted with water flood sensors to detect flooding & sound an alarm, notify individuals (including the owner, the monitoring service, & the authorities), & even shut off the building’s water supply to help minimize damage).
Wheelock offered both wire lead and screw terminal options at the same time when the 30 and 7000 series came out. That’s why models with terminals received the “T” moniker. There were also closed-grille devices with wire leads, but those were only made for about a year (wire-lead models were discontinued around 1986).
Yes, I know: I basically said all of that already.
