- 🚨 "Burglary! Burglary! Burglary! You have violated an area protected by... 🤔 a security system - leave immediately!" [voguing intensifies at 138 BPM]
I shot this video on May 4, 2023 during a service call at a client's house. She had an older Napco Gemini security system. While my partner was inside testing the panel, I managed to get this on tape. I'm telling you right now, there was something deeply unsettling about being on the edge of the woods, in the middle of the Blue Ridge Mountains, and hearing this... creepy AF. It was very much giving Wrong Turn.
The horn/speaker shown is an ADEMCO no. 749 8Ω 25-watt exterior speaker. It was loud in-person, but not nearly as loud as the Moose MPI-30.
The siren driver is a Napco MVA-1000 Multilingual Talking Siren Driver, which was very common on Gemini panels from the early-to-mid 90's. It has pre-recorded messages in English, Spanish and French. I can't imagine roaming through the woods and someone's alarm system starts yelling at me in French... shouldn't have skipped those DuoLingo lessons... - วิทยาศาสตร์และเทคโนโลยี
"You have violated an area protected by.... a security system!" It sounds like it forgot what it was for a brief moment.
😂 Yeah, he was nervous and kept forgetting his lines.
@@lollipop7ification IIRC if the person who installed it jumps a specific wire (I don't remember which), the burglary message is changed to "You have violated an area protected by a Napco security system." (IDK why the non-specialized, non-Napco-namedropping one has that pause, seems both weird AND unnecessary.)
@@lollipop7ification who is the voice of the burglar talking siren ?
@@DanknDerpyGamer You're right! There's actually a resistor on the board that gets cut to specify which message is to be played.
I wish I had an explanation for that weird pause, too. 🫤
@KevinLyons-gn7eu I'm not sure.... It's possible that it was someone who worked at Napco, or they hired a voice actor to voice those lines.
"Stop! You violated the law. Pay the court a fine or serve your sentence. Your stolen goods are now forfeit"
Break the law on my watch, will ya? I'm confiscating your stolen goods. The next move is yours: pay your fine, or it's off to jail!
That is a cool, but creepy piece of equipment! Glad to see you back again Demetri!
I know, right?! And it's great to be back. 😁
"hercules! hercules! hercules!"
yea, those things only work if you have neighbors to call the police or act as witnesses
You ever heard of Phone Diallers, and central monitoring?
He's referring to many systems that weren't set up to dial out. A lot of older systems would be installed as "local alarms" with a very loud siren driver to a.) alert the neighbors, and b.) act as a deterrent. I had an ADEMCO VISTA-20 with a Moose MPI-11 siren driver installed in 1998 in the same way.

Even though they were fully capable of dialing out to a central monitoring station, lots of people just used them as audible warning systems.
Damn, I would be terrified for life
Right?! At least it was daylight and I wasn't alone, but still...
A house my aunt use to live in had one of these voice drivers on a Magnum Alert 1016 system. It was quite the unique install with 3 LED keypads, 3 speakers, 3 motion sensors, 2 glass break sensors and 5 smoke/heat detectors. The indoor speaker (Ademco 746) was mounted in the main floor hallway. The 2 outdoor speakers (Ademco 705) were mounted outside on each end of the house. I remember testing it one time and hearing the exact tone and voice heard in the video. I never tested the fire portion, but I do know what that sounds like on the MVA1000. The house also had an unused Ademco system from the 70’s (probably installed when the house was first built) with 2 key switch stations, a buzzer horn inside and a bell box outside on the front of the house. The panel for that was mounted in a closet on the main floor (the Napco system’s panel was in the basement furnace room). They don’t live there anymore, but I remember that system clearly to this day!
That is super cool! You've got an amazing memory. The house I grew up in also had an original ADEMCO system from the 70's with those same key-switch stations, which was upgraded to a VISTA-20 in 1997/98. In 2017, I upgraded our system to a Honeywell VISTA 20P. The key-switch on the front door had remained disconnected for decades, but during the upgrade, I found the wire for it buried in the wall behind the panel. I wired it up to our brand-new system and it still works! I had to un-solder and replace the green LED, but the original red LED still works.
I've always been fascinated by these older burglar alarms.
Napco alarm systems are one of my all time favorites. I had a napco magnum alert system at my old house. instead of a siren or voice driver I had a 12-24 volt alarm bell. That got your attention hehe
Nice!! Now you made me want an alarm bell again. lol
Fascinating…
Fascinating sure for the trespassing person.
It's a Napco MVA1000 voice siren driver. The voice sounds scary than the FBII VS299 Voice siren driver
Interesting burglar alarm!
I use silent alarms. I want police (or myself) to catch the thieves. It worked great at my college apartment. Boxing day, some idiot contractor had made a key and decided he wanted to take my stuff. Alarm triggered but made no noise. Alarm company called me, I told them to call for help.
Police caught the guy still inside my place trying to carry my TV
That's really smart! Wow! Glad they caught the guy red-handed. And of all people, a contractor... on Boxing Day nonetheless. I wish silent alarms were implemented more often in residential applications like yours. Unfortunately for the average person, the likelihood of false alarms skyrockets, because they might set it off and not realize.
I do the same. It works a treat. Even disable keypad buzzers too
Holy cow
I’ve seen plenty of voice evacuation fire alarm systems and voice smoke alarms but never seen a voice security alarm
I can understand why... fire alarm voice evacs are much more common. Talking siren drivers for burglar alarms are much more níche/gimmicky, in my opinion.
Why did the man’s voice kinda forget what he was talking about?
thats something
OK, gonna be an odd question ... a few years ago I was in my basement and heard my neighbor testing their burglar alarm. It shounded **like** a Napco MVA-1000 siren, but while the siren sound was identical, and the voice sounded identical, the voice lines were in a different order. I wonder if this was me mishearing, or if there was another talking siren similar to the MVA-1000 with the lines in a different order, or not. I am so baffled.
Interesting... there might be another variant of the Napco sirens out there with the same voice, but I'm not sure. There are other talking sirens as well, like the ELK-100 and ELK-110.
The ELK-100 says, _"Warning! Warning! Warning! You have violated an area protected by a security system. The authorities have been notified. Leave immediately!"_
The ELK-110 says, _"Intruder! Intruder! Leave immediately."_
There's also the ADEMCO 745X3, which says, _"You have violated a protected area. The police were called. Leave immediately."_
Hindsight is tricky with these, as they all sound pretty similar to each other.
@@lollipop7ification I have heard the ELK-100 and 110, and ruled that one out. This is baffling. heh.
Never knew Ademco made a speaker only 748 (749)
IKR? To be fair, it's not something you would expect them to have a speaker-only version of. Although, now that I think about it, the ADEMCO WAVE2 has a speaker-only version known simply as "WAVE", if I remember correctly.
@@lollipop7ification yes and I have one of those shown in a short video I made, though the speaker quality is quite ass but it does make your ears hurt
@@ArgoSAABArgoFireSecurityMan5 I'll check it out. I'm curious to hear what it sounds like.

Was this a test or a malfunction
It was a routine test. My partner and I were called out to service a client's system, which included testing all the zones, as well as the communication path back to the central monitoring station.
@@lollipop7ification cool!!!
Hey! What if you hooked the speaker of that white burglar alarm to a very loud and large speaker and set it at very high volume so you would be able to annoy the living daylights out of any nearby thieves until they can’t take it anymore and decide to quit robbing your belongings? Can that work or not?
Also, I think you would have to wear high-noise-cancelling earmuff-headphones to prevent your eardrums from getting hurt. Or something…
That's exactly why I love these old siren drivers. I have a few high-powered 30W speakers, and they're _super_ loud. I always wear earmuffs when testing any sirens.
Check out my video on the Moose MPI-11 siren driver: th-cam.com/video/GArnmPqGphw/w-d-xo.html
It shows how to connect a bunch of those big speakers together to make an extremely loud siren setup... 125 dB! 📢
@@lollipop7ification I think you might be able to have a chance at scaring and annoying the thieves even freaking more or something…
0:23 RIP headphone users
You’re the one that set off the security alarm
It was my partner. We were there testing a customer's system, part of a routine service call. :)
So funny 😂😂😂😂😂😂😂😂
Anyone notice how it stutters
He's nervous and keeps forgetting his lines - give him a minute. lol

Ah! The Napco MVA-1000 talking siren driver.
EDIT: 0:35 - 0:41 WTF what that, at the end, it went to the steady tone used for fire alarm activations. 0 ___ o
Actually, had that happen once IRL - made a mistake of opening my window while the alarm was counting down the end of the delay period (my folks got home from somewhere), and instead of the burglary siren tone, the fire alarm steady tone played. 0 _________ o
IDK what sends chills down my spine more, the MVA-1000 siren driver's burglary tone, or the high-low alternating tone from the old Sielnt Knight Regency alarm siren.
Here is my best guess: I think it has to do with how the siren driver determines what type of alarm is occurring. When the system was disarmed (silenced) around 0:35, the panel's alarm output shut off, which caused the siren driver to reset its counting process.
The MVA-1000 is designed to continually monitor the alarm (bell) output of the panel. Believe it or not, the MVA-1000 is constantly receiving 12V power from the panel's back-up battery. It needs this constant power to be able to monitor the panel's alarm output. Whenever the panel goes into alarm, the alarm output sends a 12V signal into the siren driver. As soon as the MVA-1000 detects that voltage, the siren sounds, and it begins processing the signal. It has a logic processing circuit, which analyzes the panel's alarm output in real-time to determine if it's a steady (burglar) or pulsing (fire) alarm, and activates the appropriate siren sound + message.
Because it needs time to process the signal (count the pulses), it automatically defaults to playing a steady tone, during those 5-ish seconds that it needs. I believe the engineers who designed it would much rather the siren sound _immediately_ when it detects an alarm signal from the control panel, versus staying silent for 5 seconds while it determines the _type_ of alarm. Especially in case of fire, you want there to be an immediate alarm.
After 5 seconds, if it doesn't detect the pulses, and determines it's a burglary alarm, it plays the burglary message and switches to the yelp sound.
So why did it switch to the steady beep when the panel was disarmed? Probably because once the panel's alarm output went dead, the siren driver stopped receiving voltage, and reset its pulse count. Because the pulse count was reset, the panel reverted back to a steady tone for 5 seconds, until it realized there was no longer an alarm, and silenced itself.
@@lollipop7ification *versus staying silent for 5 seconds while it determines the type of alarm*
Silly question perhaps, but what makes determining the type of alarm take ~5 seconds?
@@DanknDerpyGamer These days, we're used to fire alarms being pulsed in Temporal Code 3, but a lot of old burglar alarm panels (pre-Y2K) did not conform to ANSI S3.41 for Audible Emergency Evacuation Signaling. As far as I know, burglar alarms weren't always required to conform to that standard. Because of this, many security panels would pulse their sirens for fire alarms like this:
ON {1 sec}
OFF {1 sec}
ON {1 sec}
OFF {1 sec}
etc.
Therefore, because of this 1-sec ON, 1-sec OFF system, 5 seconds was plenty of time for the siren driver to count the pulses and determine if it's a fire alarm or not (best 2 out of 3).
If the delay was any shorter, you run the risk of the following hypothetical scenario:
The user accidentally sets off their alarm by opening a door (intrusion alarm; steady output from the panel). It only goes off for ~2.5 seconds because the user disarms it immediately. However, the siren driver only counted for ~3 seconds. Because the signal was interrupted and it stopped counting prematurely, it could easily mistake this abrupt interruption for a fire alarm and play the wrong message. It needs that 5 seconds to determine - beyond a shadow of a doubt - that this _is_ indeed a fire alarm.

I dont get how it is creepy but that's just me.
Fair enough. At least it wasn't dark outside!
