It is a pull station, But where is the t-bar? It moved to china. Because the T-bar is gone, you have to activate with a key. Use the keyhole to activate the alarm. THIS IS ILLEGAL FOR OTHER BUILDINGS IN REAL LIFE. WHAT IF YOU NEEDED TO PULL A FIRE ALARM IN CASE THERE IS AN ACTUAL FIRE, BUT YOU DONT HAVE THE KEY?! THAT WOULD BE ILLEGAL!!!
