NBG-12LR and NBG-12LRA
Agent Release Pull Stations
Document 51369 Revision A1 ECN 01-293 09/14/01
Description
The NBG-12LR and NBG-12LRA Agent Release Pull Stations
are designed for use with Notifier control panels that include
releasing capabilities. These stations are ideally suited for areas
such as clean rooms and computer rooms, where a chemical
agent is used to extinguish a fire. Both pull stations provide a
dual-action, normally open contact, release initiating point. The
NBG-12LRA also includes a manual abort switch, System
Normal LED, and System Activated (release) LED. The dual-
action stations require pushing the handle, then pulling the handle
down for activation. Like the entire NBG-12 Series of manual
fire alarm stations, the releasing 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.
Agent Releasing Models Available
NBG-12LR. Dual action with screw terminal connections and
key lock/reset. Front of station (door) is identified with the words
"AGENT RELEASE" and a symbol illustrating discharge. This
model can be semi-flush-mounted to a standard single-gang
electrical box or surface-mounted to a SB-10 backbox.
NBG-12LRA. All features as NBG-12LR plus manual abort
switch, System Normal (power-on) LED, and System Activated

Dual Action NBG-12LR
Operation
To initiate an agent release, push in the pull
station handle then pull it down. The word
"ACTIVATED" appears after the handle is
pulled down. The agent release pull station
remains in the activated position until reset.
To reset the NBG-12LR or NBG-12LRA:
1) Unlock and open the station door. Once open, the handle
will return to the "NORMAL" position.
2) Close and lock the door. Closing the door automatically
resets the alarm switch to the "NORMAL" position.
Note: Opening the door will not activate or deactivate the alarm
switch.
Abort Feature (NBG-12LRA only)
The operation and reset of
the NBG-12LRA agent release
pull station is the same as the
NBG-12LR, with the addition of
the Abort Feature:
The System Normal LED will stay
illuminated when the Agent
Release Control Panel is "All
Systems Normal." When the
station has been activated,
initiating the agent release process
in the control panel, the System
Activated LED will illuminate.
If the control panel has been
configured to abort the releasing
of an extinguishing agent, then
pushing and holding-in the abort
switch will cancel the agent release
sequence. Please refer to the
respective agent release control
panel manual for further
instructions about using the Abort
feature.
Door 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 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.
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.
4. With the two pieces aligned and ‘keyed’ together, slide the
holes down onto the posts.
5. Holding the backplate, close the door slightly to lock the
door and backplate together.
