Likely multiple codes, each one triggers a specific hardcoded message.
I'm assuming this was from the past ("when i was a teenager") when the messages were much more generic and fixed than they are today.
- paulie_a 9y agoNo it was the same 4 codes, and the same message: "loud' It definitely is from my teenage years but whenever I visit folks I drive by that tower a block away. You can tell nothing has been upgraded
- AdamJacobMuller 9y agoThis was just a siren then? Makes sense. Smart system, really. Very simple to install/maintain and very simple to have a robust transmitter infrastructure around. If you just substitute your 4-digit code for a longer, say, 64, digit one with some time-based component, and perhaps shift the required frequency too based on time, you actually end up with a very robust very simple system.

- gnode 9y agoI disagree. The frequency hopping would make it harder for a signal jammer to prevent a legitimate transmission. If you can't predict the frequency on which the transmission is being listened for, you'd need to jam a broader spectrum, needing much more power to perform the attack.
