Operation
Push in and pull down the handle where indicated to activate the station. The NBG-12LX manual fire alarm pull
station includes one SPST (Single Pole, Single Throw) N/O (normally-open) switch and the addressable module
located inside the station. Pushing in and pulling down the dual action handle causes the N/O alarm switch to close.
The word ACTIVATED is displayed on the top of the handle when the pull station handle is pushed in and pulled
down. The activated handle can not be reset without employing the key-lock reset. To reset the NBG-12LX pull
station: 1) Insert the key and turn counterclockwise, 2) Open the door until the handle moves back into the
NORMAL position, 3) Close the door and lock it. Closing the door automatically resets the switch to the
NORMAL position.

With the door and
backplate aligned and
keyed together, slide
the holes down onto
the posts.
Closing the door slightly
locks the door and
backplate together.
1) If semi-flush mounting, proceed to step 4.
2) Mount the backbox
before
wiring to the pull station.
3) Before mounting the station, pull all necessary wiring through the backbox and
optional trim ring.
4) Remove the correct amount of wire insulation. The pull station backplate is
molded with a strip gauge to measure the amount of insulation to be removed.
5) Connect the wiring from the addressable fire alarm control panels Signaling
Line Circuit (SLC) to Terminals 1(-) and 2(+) on the NBG-12LX addressable
pull station. SLC polarity is critical for this connection.
6) Connect the wiring going to the next device on the SLC to Terminals 1 and 2,
again being certain to observe polarity.
7) If using a single-gang or SB-10 box for mounting, open the pull station door;
align the mounting holes of the pull station backplate to the backbox and screw
into place. Tighten both top and bottom screws.
8) Set the address as described in Setting the NBG-12LX Address and write the
address in the space provided on the label.
9) Close and lock the pull station door.
