Outdoor Stations
Install the NBG-12LO with a listed, outdoor-approved backbox
(WBB or WP-10) to meet UL requirements for outdoor use.
Without one of these backboxes, the NBG-12LO is not listed
for outdoor applications. Use the four supplied 8-32 x .375"
mounting screws to attach the Pull Station to the outdoor-
approved backbox.
Operation
To activate the dual-action station, first push in the handle, and
then pull the handle down. The handle locks into the activated
position. The word ACTIVATED appears after the handle is
pulled down. The pull station remains in the activated position
until reset with the key lock.
1) Reset the NBG-12LOB by
inserting the key into the
lock and turning it ¼ turn
(counter-clockwise).
2) Open the door until the
handle returns to the
NORMAL position.
3) Close and lock the door.
Closing the door auto-
matically resets the switch
to the NORMAL posi-
tion. Note: Opening the
pull station door will not
activate or deactivate the
FACP alarm switch.
