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 FlashScan or CLIP (Classic Loop Interface Protocol) mode. FlashScan is a patented (U.S. Pat. No. 5,539,389) High Speed Communications Protocol. Refer to the FACP Installation Manual to determine if FlashScan protocol is supported. FlashScan or CLIP operating mode must be selected in the FACP. (This selection is not available or required in FACPs that do not support FlashScan, 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.
mpul. If you have an older system that does not support the mpul software type, the software type mon may be used.
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.
1) Position the door and backplate side by side in the full 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 doors post hole is aligned to the backplates 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.
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.

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 the NORMAL position.

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).

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.
2) Mount the backbox before wiring to the pull station.
3) Before mounting the station, pull all necessary wiring through the backbox and optional trim ring.
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 addressable fire alarm control panels Signaling Line Circuit (SLC) to Terminals 1(-) and 2(+) on the NBG-12LX addressable pull station. SLC polarity is critical for this connection.
6) Connect the wiring going to the next device on the SLC to Terminals 1 and 2, again being certain to observe polarity.
7) 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.
8) 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.

Before installing detectors, please thoroughly read the NEMA Guide for Proper Use of Smoke Detectors in Duct Applications, which provides detailed information on detector spacing, placement, zoning, wiring, and special applications. Copies of this manual are available from NEMA (National Electrical Manufacturers Association, 2101 L Street NW, Washington, DC 20037). NFPA Standards 72 and 90A should also be referenced for detailed information.
NOTICE: This manual shall be left with the owner/user of this equipment.
IMPORTANT: This detector must be tested and maintained regularly following NFPA 72 requirements. The detector
should be cleaned at least once a year. GENERAL DESCRIPTION
An HVAC system supplies conditioned air to virtually every area of a building. Smoke introduced into this air duct system is distributed to the entire building. Smoke detectors designed for use in air duct systems are used to sense the presence of smoke in the duct.
The FSD-751RP air duct smoke detector is a photoelectric detector. This smoke detection method combines with an efficient housing design that samples air passing through a duct and allows detection of a developing hazardous condi- tion. When sufficient smoke is sensed, an alarm signal is initiated at the fire control panel monitoring the detector, and appropriate action can be taken to shut off fans, blowers and change over air handling systems, etc. This can prevent the distribution or it can isolate toxic smoke and fire gases throughout the areas served by the duct system.
Two LEDs on each detector may illuminate, if programmed by the system control panel, to provide a local alarm indica- tion. There is also a remote alarm output for use with auxiliary devices. The FSD-751RP has remote test capability with the RTS451/RTS451KEY Remote Test Station.
The FSD751RP incorporates a cover tamper feature. When the cover is removed for more than 20 minutes, the unit loses communication at the panel, a trouble is indicated at the panel and the alarm relay switches states thereby shutting down fans, dampers and blowers. In the case when the sensor is removed or when there is no power to the unit, only a trouble is indicated at the panel (alarm relay does not work any longer).
