Description
The NBG-12LX Addressable pull station is a non-coded, dual-action manual pull station with a key-lock reset feature. It provides NOTIFIER intelligent control panels with one addres-sable alarm initiating input. The addressable module is housed inside the pull station. The NBG-12LX is compatible with all Notifier intelligent panels and will automatically operate in either FlashScanTM or CLIP (Classic Loop Interface Protocol) mode. FlashScanTM is a patented (U.S. Pat. No. 5,539,389) High Speed Communications Protocol. Refer to the FACP Installation Manual to determine if FlashScanTM protocol is supported. FlashScanTM or CLIP operating mode must be selected in the FACP. (This selection is not available or required in FACPs that do not support FlashScanmt, therefore CLIP mode is enabled by default.) No selection is required in the Pull Station. The NBG-12LX meets 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.
Installation
The NBG-12LX Addressable pull station can be surface mounted to a NOTIFIER SB-10 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-12LX is to be semi-flush mounted.
Ratings
Normal Operating Voltage: 24 VDC. Average Operating Current (LED Flash): 300 p.A. Temperature Range: 32° F – 120° F (0° C – 49° C). Relative Humidity Range: 10% – 93% non-condensing.
Software Note for AM2020/AFP1010 Programming
The NBG-12LX is an Alarm Initiating Module of software type mpul’. If you have an older system that does not support thempul’ software type, the
software type ‘mon’ may be used.
Setting the NBG-12LX Address
The NBG-12LX Addressable pull station is factory preset with address `00.’ Set
the address for the pull station by turning the rotary address switches on the
addressable module mounted inside the pull station. Only one device per
address is allowed. Multiple modules may not be set to the same address on the
Signaling Line Circuit. Once the address is set, record it in the space
provided on the product ID label located inside the pull station.
To use the NBG-12LX with panels capable of supporting up to 159 addresses, pry
off the ‘break-away’ address block using a flat-bladed screwdriver. The break-
away piece is illustrated below. 
Note: LED is visible through translucent handle.
If, during mounting of the pull station, the door becomes de-tached, 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.
- Position the door and backplate side by side in the full open position. (i.e. 180-degrees with respect to each other.)
- With the backplate position fixed, move the door behind the backplate, as shown in the illustration, part A.
- 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.
- With the two pieces aligned and ‘keyed’ together, slide the holes down onto the posts. Refer to the illustration, part C.
- Holding the backplate, close the door slightly to lock the door and backplate together.
Wiring
- If semi-flush mounting, proceed to step 4.
- Mount the backbox before wiring to the pull station.
- Before mounting the station, pull all necessary wiring through the backbox and optional trim ring.
- 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.
- Connect the wiring from the addressable fire alarm control panel’s Signaling Line Circuit (SLC) to Terminals 1(-) and 2(+) on the NBG-12LX addressable pull station. SLC polarity is critical for this connection.
- Connect the wiring going to the next device on the SLC to Terminals 1 and 2, again being certain to observe polarity.
- If using a single-gang or SB-10 box for mounting, open the pull station door; align the mounting holes of the pull station backplate to the backbox and screw into place. Tighten both top and bottom screws.
- Set the address as described in ‘Setting the NBG-12LX Address’ and write the address in the space provided on the label. 9) Close and lock the pull station door.
Operation
Push in and pull down the handle where indicated to activate the station. The
NBG-12LX manual fire alarm pull station includes one SPST (Single Pole, Single
Throw) N/O (normally-open) switch and the addressable module located inside
the station. Pushing in and pulling down the dual action handle causes the N/O
alarm switch to close. The word ‘ACTIVATED’ is displayed on the top of the
handle when the pull station handle is pushed in and pulled down. The
activated handle can not be reset without employing the key-lock reset. To
reset the NBG-12LX pull station: 1) Insert the key and turn counterclockwise,
2) Open the door until the handle moves back into the NORMAL’ position, 3) Close the door and lock it. Closing the door automatically resets the switch to theNORMAL’ position.
Note – Opening the pull station door will not activate or deactivate the
alarm switch.
With the door and backplate aligned and ‘keyed’ together, slide the holes down
onto the posts. 
CAUTION!
Install the Notifier NBG-12LX manual pull station in accordance with these
instructions, applicable NFPA standards, national and local Fire and
Electrical codes and the re-quirements of the AHJ (Authority Having
Jurisdiction). Regular testing of the devices should be conducted in
accordance with the appropriate NFPA standards. Failure to fol-low these
directions may result in failure of the device to report an alarm condition.
Notifier is not responsible for devices that have been improperly installed,
tested or maintained.
For ADA compliance, if the clear floor space only allows forward approach
to an object, the maximum forward reach height allowed is 48 in. (1,220 mm).
If the clear floor space allows parallel approach by a person in a wheelchair,
the maximum side reach height allowed is 54 in. (1,370 mm).
