BG-12LR and BG-12LRA Agent Release Pull Station
Patented, U.S. Patent No. Des. 428,351; 6,380,846; Other Patents Pending
Document 51370 I56-2265-003
Description
The BG-12LR and BG-12LRA Agent Release Pull Stations are designed for use with
Fire•Lite 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 extin-
guish a re. Both pull stations provide a dual-action, normally open contact (N/O), release
initiating point with a key-lock reset feature. The BG-12LRA also includes a manual abort
switch, System Normal LED, and System Activated (release) LED. Both stations meet the
ADAAG controls and operating mechanisms guidelines (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.
Ratings
Switch contact (N/O) is gold plated for reliability and rated at 0.25 A at 30 volts (AC or
DC).
Installation
The BG-12LR pull station can be surface mounted to an SB-10 or SB-I/O surface backbox
or semi-ush 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 BG-12LR is to be semi-ush
mounted. The BG-12LRA 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.

Wiring
CAUTION! Do not detach the door of the pull station during installation. The door of
the pull station cannot be reattached to the backplate after the backplate has already been
installed onto an electrical box.
CAUTION!
Install the Fire•Lite BG-12LR and BG-12LRA pull station in accordance with these instructions,
applicable NFPA standards, national and local Fire and Electrical codes and the requirements
of the AHJ (Authority Having Jurisdiction). Regular testing of the devices should be con-
ducted in accordance with the appropriate NFPA standards. Failure to follow these directions
may result in failure of the device to report an alarm condition. Fire•Lite is not responsible for
devices that have been improperly installed, tested or maintained.
ADA Compliance
For ADA compliance, if the clear oor space only allows forward approach to an object, the
maximum forward reach height allowed is 48 inches (121.92 cm). If the clear oor space
allows parallel approach by a person in a wheelchair, the maximum side reach allowed is
54 inches (137.16 cm).

Abort Feature (BG-12LRA only)
The operation and reset of the BG-12LRA agent release pull station is the same as the BG-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, ini-
tiating the agent release process in the control panel, the System Activated LED will illuminate.
If the control panel has been congured 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 us-
ing the Abort feature.
Abort Plate Wiring (BG-12LRA only)
Connect the wiring from the agent release control panel’s Abort Circuit to the wire leads
D&E of the normally open abort switch. Connect 24 VDC (+) to a form-c relay, this relay
shall be called the Release Relay. Connect the relay's normally closed contact to the System
Normal LED wire lead A. Connect the relays normally open contact to the System Activated
LED wire lead B. Connect the 24 VDC (–) to the LED assembly ground wire C.

WARNING
When used for CO2 releasing applications, observe proper precautions as stated in NFPA
12. Do not enter the protected space unless physical lockout and other safety procedures
are fully completed. Do not use software disable functions in the panel as lockout. For ADA
compliance, if the clear oor space only allows forward approach to an object, the maxi-
mum forward reach height allowed is 48 inches (121.92cm). If the clear oor space allows
parallel approach by a person in a wheelchair, the maximum side reach height allowed is
54 inches (137.16cm).
