This sensor must be installed in compliance with the control panel system installation manual. The installation must meet the requirements of the Authority
Having Jurisdiction (AHJ). Sensors offer maximum performance when installed in compliance with the National Fire Protection Association (NFPA); see NFPA
72..
GENERAL DESCRIPTION
Model FSL-751 is a plug-in type smoke sensor that uses a laser based photoelectronic sensing chamber. The sensor uses analog-addressable communications
to transmit smoke density and other information to the control panel.
Two LEDs on each sensor light to provide a local, visible sensor indication. Remote LED annunciator capability is available as an optional accessory (Part No.
RA400Z).
Notifier panels offer different features sets across different models. As a result, certain features of the product may be available on some control panels, but not
on others. The possible features available in the product, if supported by the control unit are:
1. The panel controls the LED operation on the sensor. Operational modes are RED blink, RED continuous, GREEN blink, and off.
2. The remote output may be synchronized to the LED operation or controlled independent of the LEDs.
Please refer to the operation manual for the UL listed control unit for specific operation of the FSL-751.

SPACING
Notifier recommends spacing sensors in compliance with NFPA 72. In low air flow applications with smooth ceilings, space sensors 30 feet apart. For specific
information regarding sensor spacing, placement, and special applications, refer to NFPA 72 or Notifier’s System Smoke Detector Application Guide , available
at no charge from Notifier.
WIRING INSTRUCTIONS
All wiring must be installed in compliance with the National Electrical Code, applicable local codes, and any special requirements of the Authority Having
Jurisdiction. Proper wire gauges should be used. The installation wires should be color-coded to limit wiring mistakes and ease system troubleshooting. Improper
connections will prevent a system from responding properly in the event of a fire.
Disconnect power from the communication line before installing sensors.
All wiring must conform to applicable local codes, ordinances, and regulations.
1. Wire the sensor base (supplied separately) per the wiring diagram (Figure 1).
2. Set the desired address on the sensor address switches.
NOTE: Some panels support extended addressing. In order to set the sensor above address 99
on compatible systems, carefully remove the stop on the upper rotary switch with thumb as
shown in Figure 2.
3. Install the sensor into the sensor base. Push the sensor into the base while turning it clockwise
to secure it in place.
4. After all sensors have been installed, apply power to the control unit and activate the commu-
nication line.
5. Test the sensor(s) as described in the TESTING section of this manual.
CAUTION
Dust covers provide limited protection against airborne dust particles during shipping. Dust covers
must be removed before the sensors can sense smoke. Remove sensors prior to heavy remodeling
or construction.
TESTING
Before testing, notify the proper authorities that the system is undergoing maintenance, and will

temporarily be out of service. Disable the system to prevent unwanted alarms.
All sensors must be tested after installation and periodically thereafter. Testing methods must satisfy the Authority Having Jurisdiction (AHJ). Sensors offer
maximum performance when tested and maintained in compliance with NFPA 72. The sensor can be tested in the following ways:
A. Functional: Magnet Test (P/N M02-04-01 or M02-09-00)
This sensor can be functionally tested with a test magnet. The test magnet electronically simulates smoke in the sensing chamber, testing the sensor elec-
tronics and connections to the control panel.
1. Hold the test magnet in the magnet test area as shown.
2. The sensor should alarm the panel.
Two LEDs on the sensor are controlled by the panel to indicate sensor status. Coded signals, transmitted from the panel, can cause the LEDs to blink, latch
on, or latch off. Refer to the control panel technical documentation for sensor LED status operation and expected delay to alarm.
B. Smoke Entry: Aerosol Generator (Gemini 501)
The Gemini model 501 aerosol generator can be used for smoke entry testing. Set the generator to represent 4%/ft. to 5%/ft. obscuration as described in
the Gemini 501 manual. Using the bowl shaped applicator, apply aerosol until the panel alarms.
A sensor that fails any of these tests should be cleaned as described under CLEANING, and retested. If the sensor fails after cleaning, it must be replaced and
returned for repair.
When testing is complete, restore the system to normal operation and notify the proper authorities that the system is back in operation.
CLEANING
It is recommended that the detector be removed from its mounting base to facilitate cleaning. The detector is cleaned as follows:
NOTE: Before removing the detector, notify the proper authorities that the smoke detector system is undergoing maintenance and will be temporarily out of
service. Disable the zone or system undergoing maintenance to prevent unwanted alarms.
1. Remove the detector cover by prying away the four side tabs with a small-bladed screwdriver, and then pulling the cover from the base.
2. Vacuum the screen carefully without removing it. If further cleaning is required continue with Step 3,
otherwise skip to Step 7.
3. Remove the screen assembly/chamber cover by pulling it straight out (see Figure 4).
4. Clean the chamber by vacuuming or blowing out dust and particles.
5. Replace the sensing chamber cover, aligning the arrow on the top with arrow on the printed circuit
board.
6. To replace the screen, place it over the chamber assembly, turning it until it snaps into place.
7. Replace the cover using the LEDs to align the cover and then gently pushing it until it locks into place.
8. Reinstall the detector.
9. Test the detector as described in TESTING.
10. Reconnect disabled circuits.
11. Notify the proper authorities that the system is back on line.
Laser Safety Information
This smoke detector does not produce any hazardous laser radiation and is certified as a Class 1 laser
product under the U.S. Department of Health and Human Services (DHHS) Radiation Performance Standard
according to the Radiation Control for Health and Safety Act of 1968.
Any radiation emitted inside the smoke detector is completely within the protective housings and external
covers. The laser beam cannot escape from the detector during any phase of operation.
The Center of Devices and Radiological Health (CDRH) of the U.S. Food and Drug Administration implement-
ed regulations for laser products on August 2, 1976. These regulations apply to laser products manufactured
after August 1, 1976. Compliance is mandatory for products marketed in the United States.
CAUTION
Use of controls, adjustments, or performance of procedures other than those specified in this manual may result in hazardous radiation exposure.
