Description:

The BG-12LA Pull Station is a non-coded manual pull station which provides a Fire Alarm Control Panel (FACP) with a single alarm initiating input signal. The pull station also provides a second set of contacts rated up to 3 Amps at 30 volts (AC or DC), for auxiliary functions. The BG-12LA is a dual action model equipped with a key lock reset. It is UL listed and meets the ADA requirement of a 5-lb. maximum pull down force to activate. Operating instructions are molded into the handle. Molded terminal numbers can also be found adjacent to the wiring terminals.

Mounting

Surface mount the BG-12LA pull station to a SB-10 surface backbox. Semi-flush mount the BG-12LA to a standard singlegang, double-gang, or 4-inch (10.16 cm) square electrical box.

Operation

1) Before mounting the pull station, pull all necessary wiring through the backbox.

2) Remove the correct amount of wire insulation. The pull station’s backplate is molded with a strip gauge to measure the amount of insulation to be removed.

3) Connect the wiring from the fire alarm control panel’s Initiating Device Circuit (IDC), or any previous device on the IDC to terminals 1 and 2 located on the pull station’s terminal strip. Connect the next device on the IDC or Endof-Line Resistor (ELR) to terminals 1 and 2. Note: Maintain consistent polarity with all connections throughout the IDC.

4) Connect the wiring for the normally open (N/O) auxiliary switch circuit to terminals 3 & 4.

To activate the dual-action station, first push in the handle, and then pull the handle down. The handle locks into the activated position. The word ‘ACTIVATED’ appears after the handle is pulled down. The pull station remains in the activated position until reset with the key lock.

1) Reset the BG-12LA by inserting the key into the lock and turning it ¼ turn (counter-clockwise).

2) Open the door until the handle returns to the ‘NORMAL’ position.

3) Close and lock the door. Closing the door automatically resets the switch to the ‘NORMAL’ position. Note: Opening the pull station door will not activate or deactivate the FACP alarm switch or the auxiliary function switch.
