The alarm is a white rectangle that is mounted on a wall. It has a red frame around it.
When pushed, it creates a large alarm that rings through the area, and Meat Puppets come to check it out. They will shoot you when they find you. If it is turned on, you have to turn it off or they will keep coming. It is turned on by Labcoats and Construction Workers.
- The alarms look very similar to the switches in the Psi Practice Room.
- It can be activated by the player.
