Definitely sounded like one, esp. the EM variety.
I just posted a new video of my current fire alarm system. Another video with all of my collection will be posted soon.
A video of Dan B. testing some kind of Simplex 4005 fire alarm system (probably replacing a 2001) that has a mix of Simplex 2903+2901-9806 horn/lights and 4903-9219 horn/strobes on 20bpm March Time (but the 2903 lights flash at 120bpm).
- Gotta love fire alarms at conventions. This is at the Baltimore Convention Center. You can hear bits and pieces of the EVAC message. The tone you hear is a steady tone that sounds for 6 seconds.
http://www.youtube.com/watch?v=N40hxQdmBOw&feature=related - Simplex True Alerts in code 3.
- Simplex 4903 electromechanicals in continuous. If you listen closely, the horn skips whenever the strobe flashes.
- TrueAlerts in code-3 (skip to 4:28). Note that once they’re outside there’s an AS or MT in code-3 and it’s actually in sync with the TrueAlerts.
- More airport fun - Orlando Int’l. Ceiling-mount Integrety speaker/strobes with slow whoop.
- A somewhat rare find these days - 7002Ts.

- Customed 4100U voice EVAC. White TrueAlert speaker/strobe seen in the hallway.
- Girl pulls what looks like a BG-8 pull station setting off a Wheelock SafePath system and electronic horns.
