Simplex Fire Strobe
|
I like these. My elementary school (1992) had these. This is a medical building where my eye doctor is located. I assume this is from the 80s or 90s. What's interesting about these is that instead of a strobe light, it's got a normal halogen bulb that lights up each time the alarm buzzes (at least that's how the ones at my elementary school went).
The ones at my elementary school would do "march time" which is "HONK HONK HONK ... HONK HONK HONK ... HONK HONK HONK".
