Description

The NBG-12 Series Pull Stations are non-coded manual pull stations that provide a Fire Alarm Control Panel (FACP) with a single alarm initiating input signal. The NBG-12 series includes both single-action and dual-action models equipped with either a hex or key lock/reset. A single-action pull-station is activated by a single pull-down of the alarm handle. The dual-action versions require pushing in the handle, then pulling the handle down for activation. The NBG-12 series manual pull 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 along with Braille text. Molded terminal numbers can be found adjacent to the wiring terminals.
NBG-12 Series Models available:

• NBG-12S – Single action with ‘pigtail’ connections and a hex lock reset. Pigtail wires are provided for connection to the Fire Alarm Control Panel’s (FACP) Initiating Device Circuit (IDC).
• NBG-12 – Dual action model with screw terminal connections and a hex lock reset.
• NBG-12L – Same as NBG-12 except with a key lock reset.
• NBG-12LSP – Same as NBG-12L except with both English and Spanish operating instructions.

Switch Contact Rating
All switch contacts are rated for 0.25 A at 30 volts (AC or DC).

Installation

Surface mount the NBG-12 pull station to an SB-10 surface back box.
Semi-flush mounts the NBG-12 to a standard single gang, double-gang, or 4-inch (10.16 cm) square electrical box. Mount the optional Trim Ring (BG-TR) if necessary when semi-flush mounting the unit.

If, during mounting of the pull station, 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 the backbox.

1. Position the door and backplate side by side in the fully open position. (i.e. 180 degrees with respect to each other.)
2. With the backplate position fixed, move the door behind the backplate, as shown in the illustration, part A.
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. Refer to the illustration, part B.
4. With the two pieces aligned and ‘keyed’ together, slide the holes down onto the posts. Refer to the illustration, part C.
5. Holding the backplate, close the door slightly to lock the door and backplate together.

DOOR ATTACHMENT
With the door and backplate aligned and ‘keyed’ together, slide the holes down onto the posts.
Closing the door slightly locks the door and backplate together.

WARNING! Do not loop wiring under any terminals. Break wire runs to maintain IDC supervision.
Wiring Instructions for the NBG-12, NBG-12L, and NBG-12LSP

1. If semi-flush mounting, proceed to step 4.
2. Mount the backbox before wiring to the pull station.
3. Before mounting the station, pull all necessary wiring through the backbox and optional BG-TR.
4. Remove the correct amount of wire insulation. The pull station backplate is molded with a strip gauge to measure the amount of insulation to be removed.
5. Connect the wiring from the fire alarm control panel’s IDC, or any previous device on the IDC, to terminals 1 and 2 on the pull stations terminal strip. Connect the next device on the IDC or End-of-Line Resistor (ELR) to terminals 1 and 2.
6. Maintain consistent polarity with all connections throughout the IDC.

Wiring Instructions for the NBG-12S
Follow instructions 1 through 3 above, then proceed with steps 4 and 5 following:
4) Connect the field wiring from the FACP’s IDC, or the previous device on the IDC, to the pull station’s ‘pigtails’. Connect the positive (+) IDC wire to a red pigtail, and the negative (-) IDC wire to a black pigtail. Next, connect the positive (+) wire going to the next device or an ELR to the remaining red positive (+) ‘pigtail’. Connect the negative (-) wire going to the next device or an ELR to the remaining black negative (-) pigtail.
5) Maintain consistent polarity with all connections throughout the IDC.

Operation

To activate a single-action pull station, simply pull down the handle. To activate dual-action stations, push in, then pull down the handle. The word ‘ACTIVATED’ appears after the handle is pulled down. The pull station remains in the activated position until reset.

1. To reset the NBG-12S and NBG-12 hex lock pull stations, work the supplied 9/64-inch hex wrench into the lock until firmly seated and turn counterclockwise 1/4 turn.
   To reset the NBG-12L and NBG-12LSP key lock stations, insert the key and turn counterclockwise 1/4 turn.

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 alarm switch.

CAUTION
Install the pull station in accordance with the supplied instructions, applicable NFPA standards, national and local Fire and Electrical codes, and the requirements of the authority Having Jurisdiction (AHJ). Conduct regular testing of the devices using appropriate NFPA standards. Notifier is not responsible for devices that have not been properly installed, tested, or maintained.
For ADA compliance, if the clear floor space only allows a forward approach to an object, the maximum forward reaches height allowed is 48 inches (121.92 cm). If the clear floor space allows a parallel approach by a person in a wheelchair, the maximum side reach height allowed is 54 inches (137.16 cm).
