The hospital call things I’ve looked at are wired into the tv control, and theres usually a pullcord in the bathroom that’s supposed to be tied so you can reach it from the shower. When you pull it this weird little clear plastic reset button pops up and starts blinking. When you push it back in it resets. I’m gonna try using one as a lightswitch, I haven’t unscrewed one to look into it yet. The nurse desks have weird panels where the nurse calls beep and light up, there’s some kind of intercom but I have no idea how to work it. The control box is hidden in a wall, I found it because I heard the blink relay for the room light clicking after I set one off in a room. The newer ICU ward has a digital nurse call hidden in the headboard.
The hospital I go to has the same standpipe like the one you posted but it’s behind a door with a glass window and with old shiny silver water/CO2 extinguishers back there. Most of the standpipes are dead now but if I find a live one I’d like to try using it. They’ve got those cheap plastic nozzles but I’ve used one of those with a city hydrant wetting down dust and that stream was crazy.
I will fix them now. I just got back from a b-ball tournament. The two pictures that i Can’t put up is the gas and line pressure panels. I had
them on imageshack, But I deleted them. Then, I deleted them off my camera! That was a huge mistake. Sorry, Everyone.
The “map” is actually a graphic annunciator. It tells basically where the alarm is from on the map. It was really cool to see it when I got to pull the fire alarm. It flashed on the map below “Lobby” then on the side it gave more information such as “Pull Station” “Lobby”
I’ll bet you anything that the first picture of the pullstation, when it’s pulled, it calls some one to that pull to acknowlege if there’s a fire first, then if there is, the guy uses a key for that key switch behind the pull bar and that sets off the alarms.
