Document 51369
Description
The NBG-12LR, NBG-12LRA, and NBG-12LRAA 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. These pull stations provide a dual-action, normally open contact
(N/O), release initiating point with a key-lock reset feature. The NBG-12LRA and NBG-
12LRAA also include a manual abort switch, System Normal LED, and System Activated
(release) LED. These stations meet the ADAAG controls and operating mechanisms guide-
lines (section 4.1.3[13]), and the ADA requirement for a 5 lb. maximum pull force to activate
the pull station. Operating instructions are molded into the pull station handle along with
Braille text. Molded terminal numbers are also present. NBG-12LRAA is compliant with
ULC S527-11/ULC S528-14 requirements for releasing applications with abort functionality.
Ratings
Switch contact (N/O) is gold plated for reliability and rated at 0.25 A at 30 volts (AC or DC).
Installation
The NBG-12LR pull station can be surface mounted to an SB-10 or SB-I/O surface
backbox or semi-flush mounted on a standard single-gang, double-gang or 4" (10.16 cm)
square electrical box. The optional BG-TR trim ring can be used if the NBG-12LR is to be
semi-flush mounted. The NBG-12LRA and NBG-12LRAA must be surface-mounted to a
SBA-10 backbox.
Operation
To initiate an agent release, push in and pull down on the handle. The word 'ACTIVATED'
appears after the handle is pulled down. This will remain until the pull station is reset.
The pull station includes one Single Pole, Single Throw (SPST) Normally Open (N/O)
switch which closes upon activation of the pull station.
Resetting the Pull Station
1. Insert the key into the lock and rotate 1/4 turn counterclockwise.
2. Open the door until the handle returns to normal.
3. Close and lock the door.
NOTE: Closing the door automatically resets the switch to the 'Normal' position. Open-
ing the door will not activate or deactivate the alarm switch.
