tabletop unit.

Direct Plug
In its "as shipped" configuration, the unit is ready to be
plugged directly into a wall socket.
To install:
• Choose a standard, unswitched 120 V outlet to plug
alarm into.
• Pull the slide support out approximately 6 mm (1/4")
until slide snaps in place (this will help support unit in
wall outlet).
• Plug the alarm into an electrical outlet.
Mounted horizontally (sideways):
If you are going to use your alarm as a direct plug and you
are going to plug in to an outlet that is mounted
horizontally (sideways), you will need to rotate the
adaptor 90˚. To rotate the adaptor:
• With back of unit facing you (adaptor at the top), place
your thumbs on the thumb grips.
• With your thumbs, push down in the direction of the
arrows on the thumb grips and slide back door off.
