Description
The NBG-12 Series Pull Stations are non-coded manual pull
stations which provide a Fire Alarm Control Panel (FACP)
with a single alarm initiating input signal. The NBG-12
series includes both single-action and dual-action models
equipped with either a hex or key lock / reset. A single-action
pull-station is activated by a single pull-down of the alarm
handle. The dual-action versions require pushing in the
handle, then pulling the handle down for activation. The
NBG-12 series manual pull stations are UL listed and meet the
ADA requirement of a 5-lb. maximum pull force to activate.
Operating instructions are molded into the handle along with
Braille text. Molded terminal numbers can be found adjacent
to the wiring terminals.
NBG-12 Series Models available:
NBG-12S – Single action with 'pigtail' connections and
a hex lock reset. Pigtail wires are provided for connec-
tion to the Fire Alarm Control Panel's (FACP) Initiating
Device Circuit (IDC).
NBG-12 – Dual action model with screw terminal
connections and a hex lock reset.
NBG-12L – Same as NBG-12 except with a key lock reset.
NBG-12LSP – Same as NBG-12L except with both
English and Spanish operating instructions.

If, during mounting of the pull station, the door becomes de-
tached, 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 the backbox.
1. Position the door and backplate side by side in the full open
position. (i.e. 180 degrees with respect to each other.)
2. With the backplate position fixed, move the door behind the
backplate, as shown in the illustration, part A.
3. 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's
hinge post. Refer to the illustration, part B.
4. With the two pieces aligned and 'keyed' together, slide the holes
down onto the posts. Refer to the illustration, part C.
5.
Holding the backplate, close the door slightly to lock the door
and backplate together.
