The pull station is a dual-action model equipped with a key lock reset, an approved outdoor gasket, and an accompanying outdoor back box. It is UL listed and meets the ADA requirement of a 5-lb. maximum pull-down force to activate. Operating instructions are molded into the handle.

The features of the pull station include Dual-Action operation, a Key-Lock
Reset function, Screw Terminal Wire connections, an outdoor-use gasket, an
outdoor-approved 4-inch backbox, and a sealed switch with gold-plated
contacts.
Note: The NBG-12LOB is applicable with the WP-10 backbox in retrofit
applications. To meet UL requirements for outdoor use, the NBG-12LO Pull
Station must be mounted to the WBB or WP-10 Backbox to create the NBG-12LOB
model.

Door Attachment and Reattachment
If the door becomes detached, complete the following steps to reattach the door to the backplate. The door cannot be connected to the pull station if the unit is mounted to a back box.
- Position the door and backplate side by side in the fully open position. (i.e. 180 degrees with respect to each other.)
- With the backplate position fixed, move the door behind the backplate, as shown in the illustration, part A.
- Align the hinge posts and holes by bringing the door up to meet the backplate, paying particular attention to the keying that occurs when the door’s post hole is aligned to the backplate hinge post. Refer to the illustration, part B.
- With the two pieces aligned and keyed together, slide the holes down onto the posts. Refer to the illustration, part C.
- Holding the backplate, close the door slightly to lock the door and backplate together.
Wiring Instructions
-
Surface mount the supplied Weatherproof Backbox (WBB) using the side flanges incorporated into the backbox design.
The box can be positioned to allow conduit connection from any side. The pull station will mount in any position desired. -
Before mounting the pull station, pull all necessary wiring through the backbox.
-
Remove the correct amount of wire insulation. The pull station’s backplate is molded with a strip gauge to measure the amount of insulation to be removed.
-
Connect the wiring from the fire alarm control panels Initiating Device Circuit (IDC) or any previous device on the IDC to terminals 1 and 2 located on the pull stations terminal strip. Connect the next device on the IDC or End-of-Line Resistor (ELR) to terminals 1 and 2. Note: Maintain consistent polarity with all connections throughout the IDC.
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.
- Reset the NBG-12LOB by inserting the key into the lock and turning it ¼ turn (counter-clockwise).
- Open the door until the handle returns to the NORMAL position.
- Close and lock the door.
Closing the door auto- matically resets the switch to the NORMAL position. Note: Opening the pull station door will not activate or deactivate the FACP alarm switch.
CAUTION

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. For ADA compliance, if the clear floor space only allows a forward
approach to an object, the maximum forward reach height allowed is 48 inches
(121.92cm). If the clear floor space allows a parallel approach by a person in
a wheelchair, the maximum side reach height allowed is 54 inches (137.16cm).
