Figure 5: Installing detector into base:
1. Grasp the housing with one hand and the cover with
the other. Turn the cover counterclockwise fully (approx.
30 degrees) and remove cover by pulling it away from
detector unit (see Figure 4).
2. Replace with new filter and cover assembly. The cover
is keyed so it fits in place only one way. Turn the cover
clockwise until it stops.
NOTE: The base is equipped with an optional tamperproof
feature which can be used to prevent unintentional removal
of the unit while replacing the filter.
If a clogged filter was the cause of the trouble condition,
normal detector operation should resume automatically
within five minutes. If the trouble condition persists, the
detector must be returned for repair or replacement.
Installing Detector Into Base
1. Align the detector at a right angle to the base, with the
five wires and connectors adjacent to the connector
receptacle as shown in Figure 5.
2. Plug the wired connector into the receptacle.
3. Rotate the detector into the base, making sure detector
and base keyed fit is lined up. Turn the detector clock-
wise until it snaps into place.
IMPORTANT: FSH-751 will only operate with B710HD/
B524FTXE Mounting Base.

Before Installing
This detector must be installed in compliance with the con-
trol panel system installation manual. The installation must
meet the requirements of the Authority Having Jurisdiction
(AHJ). Detectors offer maximum performance when
installed in compliance with the National Fire Protection
Association (NFPA); see NFPA 72.
General Description
The FSH-751 Smoke Detector uses a small air intake fan
and a high density replaceable filter. Air and smoke are
drawn into a photoelectric sensing chamber while airborne
particulate and water mist are removed. The address-
able-analog detector transmits an analog representation
of smoke density over a communication line to a control
panel. Rotary decade switches are provided for setting the
sensor’s address.
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 FSH-751 may be
available on some control panels, but not on others. The
possible features available in the FSH-751, 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, GREEN continuous, 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 con-
trol unit of specific operation of the FSH-751.
The FSH-751 smoke detector is intended for use in nor-
mal environmental conditions, where dust and other
airborne particulate are present at elevated levels.
These elevated levels tend to cause false alarms and
high maintenance in standard detectors. FSH-751 pro-
vides a protective enclosure for a photoelectric smoke
detector chamber and allows smoke detection in areas
that tended to use exclusively heat detection.
FSH-751 requires compatible addressable communica-
tions to function properly. Connect this detector to
listed-compatible control panels only.
Spacing
Notifier recommends spacing detectors in compliance
with NFPA 72. In low air flow applications with smooth
ceilings, space detectors 30 feet apart. For specific infor-
mation regarding sensor spacing, placement, and special
applications, refer to NFPA 72 or the System Smoke Detector
Application Guide available from Notifier.
Duct Applications
FSH-751 is listed for use in ducts. See Duct Applications
Guide A05-1004 for details on pendant mount applica-
tions.

WARNING
FSH-751 is not designed to operate in explosive environments.
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.
Remove power from the communication line before
installing detectors.
All wiring must conform to applicable local codes, ordi-
nances, and regulations.
1. Wire the sensor base per the wiring diagram, please see 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. Insert 5-wire connector on mounting base into 5-pin connector on the
unit. Install the detector into the sensor base. Push the detector into the
base while turning it clockwise to secure it in place. (Please see Figure
5 and INSTALLING DETECTOR INTO BASE on page 4 for specific direc-
tions.
4. After all detectors have been installed, turn on the auxiliary power sup-
ply, then apply power to the control unit and activate the communica-
tion line.
5. Test the detector(s) as described in the TESTING section of this
manual.
CAUTION
Dust cover must be removed before the detector can sense smoke.
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 detectors must be tested after installation and periodi-
cally thereafter. Testing methods must satisfy the Authority
Having Jurisdiction (AHJ). Detectors offer maximum per-
formance 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 detector can be functionally tested with a test magnet. The test
magnet electronically simulates smoke in the sensing chamber, testing
the detector electronics and connections to the control panel.
1. Hold the test magnet in the magnet test area as shown in Figure 3.
2. The detector should alarm the panel. Two LEDs on the detector 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
detector LED status operation and expected delay to alarm.
B. Smoke Entry: Aerosol Generator
Aerosol generators for smoke entry testing are available from a number
of third party manufacturers (e.g., Gemini Scientific). Following the
manufacturer’s instructions, apply aerosol until the panel alarms.
A detector that fails any of these tests should be retested.
If the detector still fails any test, have its filter replaced (see
instructions below) and retested. Finally, if the detector con-

Figure 4. Replacing the filter cover:
tinues to fail after replacing the filter, it must be returned for
repair or replacement.
When testing is complete, restore the system to normal
operation and notify the proper authorities that the system
is back in operation.
Cleaning
The unique design of the FSH-751 eliminates the need for
typical detector cleaning. The only maintenance necessary
is replacing the filter, which is signaled by a trouble condi-
tion at the panel (see below).
The FSH-751 smoke detector has been designed to maxi-
mize the amount of time before maintenance is required.
The detector utilizes a replaceable filter that may become
clogged over time. The detector monitors itself to insure
that the filter has not become clogged. Because environ-
mental conditions can vary significantly, the amount of time
before maintenance could vary significantly as well. To fully
understand the maintenance requirements of the FSH-751 in
its installed location, it is recommended that the following
test program be conducted.
1. Install the FSH-751 detector in the desired location.
2. Connect the detector to the fire alarm control panel.
3. Maintain a record for at least 90 days of any mainte-
nance performed on or required by the detector.
4. At the end of the test period, use the record to develop
and schedule maintenance. The FSH-751 should be
serviced at regular intervals to insure that the fire alarm
system provides continuous protection.
Replacing the Filter
IMPORTANT:
When the filter becomes too clogged to draw adequate air into
the unit, power is automatically cut from the detector, sending
a trouble signal to the fire control panel. After 5 minutes, power
is restored to the detector for 72 hours. After 72 hours, power is
cut again and the detector will remain off-line until the filter is
replaced.
Note: The unit has two filters. The replaceable filter is inside the cover. A
permanent filter is mounted to the unit.
Alignment marks are
provided on the cap
and top of the perma-
nent filter.
