Wiring Instructions for the NBG-12, NBG-12L and NBG-12LSP
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 BG-TR.
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 fire alarm control panel's IDC, or any previous device on the IDC, to terminals 1 and 2 on the
pull stations terminal strip. Connect the next device on the IDC or End-of-Line Resistor (ELR) to terminals 1 and 2.
6) Maintain consistent polarity with all connections throughout the IDC.
Wiring Instructions for the NBG-12S
Follow instructions 1 through 3 above, then proceed with steps 4 and 5 following:
4) Connect the field wiring from the FACP's IDC, or the previous device on the IDC, to the pull station's 'pigtails'. Connect
the positive (+) IDC wire to a red pigtail, and the negative (-) IDC wire to a black pigtail. Next, connect the positive (+)
wire going to the next device or an ELR to the remaining red positive (+) 'pigtail'. Connect the negative (-) wire going to
the next device or an ELR to the remaining black negative (-) pigtail.
5) Maintain consistent polarity with all connections throughout the IDC.
Operation
To activate a single-action pull station, simply pull-down the handle. To activate dual-action stations, push-in,
then pull-down the handle. The word 'ACTIVATED' apears after the handle is pulled down. The pull station
remains in the activated position until reset.
1) To reset the NBG-12S and NBG-12 hex lock pull stations, work the supplied 9/64-inch hex wrench into the
lock until firmly seated and turn counterclockwise 1/4 turn.
To reset the NBG-12L and NBG-12LSP key lock stations, insert the key and turn counterclockwise 1/4 turn.
2) Open the door until the handle returns to the 'NORMAL' position.
3) Close and lock the door. Closing the door automatically resets the switch to the 'NORMAL' position.
Note – Opening the pull station door will not activate or deactivate the alarm switch.
CAUTION
Install the pull station in accordance with the supplied instructions, applicable NFPA standards, national and local Fire and Electrical
codes and the requirements of the Authority Having Jurisdiction (AHJ). Conduct regular testing of the devices using appropriate NFPA
standards. Notifier is not responsible for devices that have not been properly installed, tested or maintained.
