To the left of the fire door, set into an inside wall, is a large metal panel 
marked Danger High Voltage. She knew it would be here because she’s consulted
the building plans. The panel was pivotal in her planning. Now, she pulls the 
panel open and hooks a small diagnostic comp over the lower flange, then draws 
out a section of white- and orange-striped wire. Using an Armalite multitool, 
she strips a short section of its insulated plastic coating, connects two leads 
from the Telex comp to the stripped section of wire, then cuts the wire between 
the two leads. This effectively disables the motion detectors monitoring each of 
the stairway landings above her.
