Re: Quiet hospital fire alarm

I would check out this article. Also see this presentation on private mode signaling. From what I can understand, the alarms can be quiet for a few reasons. First, in operating rooms, a loud fire alarm can startle a surgeon. Also, there is no need to notify the occupants since most of them are incap...

Re: What is your favorite electronic horn sound?

I voted for the Edwards Integrity because it sounds like a mechanical horn. I'm not a big fan of the 892's tone for some reason.

Re: why do we have to do fire drills once a month

I don't remember where I read it, but I think one of the reasons is as follows. By doing fire drills very frequently, occupants become accustomed to it, to the point where when the alarm sounds, they will automatically assume that it is a fire drill instead of an actual fire. That way, if there is a...

Re: What tones would you prefer for voice evac?

One of my favorite voice evacuation messages is this one: QHXLsTrrHwY I believe it's a custom message, judging by the click when the message ends. I wish all evac messages sounded like this. It's very concise and the speech is clear. I don't remember who it was but someone on this board recorded the...

Here's a 5721B:
Wow, thank you! I've seen this panel in a couple of buildings but never knew the model number. The only things I knew about it were its modular design and the "signals timed out" lamp.

Fun fact: one of the systems that had this panel exclusively used ADT-branded BG-10s. Weird.

Not withstanding my idiotic contributions to this thread three years ago, I now use a 90s Lenovo keyboard. It has a buckling spring keyboard like the IBM Model M or the Wheelwriter.

Re: Daily Fire Alarm Question!

What is the history of the "WHEN BELL RINGS DIAL 911" compliance signs? Was this because old fire alarm systems lacked the ability to dial 911 on their own due to limited technology? What dictates the use of such sign? Is there some sort of safety code surrounding this that mandates their use? I ha...

Re: Simplex 4903 NAs being replaced at local supermarket.

OMG this is so similar to the situation at school. Some -9846/9105s that got directly replaced by the Siemens speaker/strobes have a visible rectangle on the left side. I believe it’s dust. It sounds like they painted the wall at some point and painted around the device. The rectangle would be the ...

Re: What is your favorite soda pool

How 'bout a Fresca? ??? Fresca is a soda. What I wrote is a line from the classic 1980 film Caddyshack. Technically my favorite soda is Polar Orange, however this beverage is sold locally in parts of the northeast and no one else here would be familiar with it, so I just listed Fresca which has a s...

The NAC on the 4001 also is FWR.
To an enthusiast, the difference between filtered and FWR is whether or not mechanical horns sound raspy. How come mechanical horns on a 4001 don't sound raspy? Can a panel output FWR but not to the level where it affects horn operation?
