Fire-LITe Alarms BG-12LR Agent Release Pull Station User
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 fire. 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-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 BG-12LR is to be semi-flush 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
- Insert the key into the lock and rotate 1/4 turn counterclockwise.
- Open the door until the handle returns to normal.
- 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.
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 floor space only allows forward approach to
an object, the maximum forward reach height allowed is 48 inches (121.92 cm).
If the clear floor 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 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.
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 floor space only
allows forward approach to an object, the maxi-mum forward reach height
allowed is 48 inches (121.92cm). If the clear floor space allows parallel
approach by a person in a wheelchair, the maximum side reach height allowed is
54 inches (137.16cm).
