NO-400-006 1 I56-3524-006R
This sensor must be installed in compliance with the control panel system
installation manual. The installation must meet the requirements of the Au-
thority Having Jurisdiction (AHJ). Sensors offer maximum performance when
installed in compliance with the National Fire Protection Association (NFPA);
see NFPA 72.
GENERAL DESCRIPTION
Models FSP-851, FSP-851T and FAPT-851 are plug-in type smoke sensors that
combine a photoelectronic sensing chamber with addressable-analog commu-
nications. The sensors transmit 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 the sensor are controlled by the panel to indicate sensor status.
An output is provided for connection to an optional remote LED annunciator
(P/N RA400Z/RA100Z). Models FAPT-851 and FSP-851T combines a photoelec-
tronic sensing chamber and 135°F (57.2°C) fixed temperature heat detector. The
FAPT-851 also transmits an alarm signal due to heat (135°F fixed) per UL 521.
Notifier panels offer different features sets across different models. As a result,
certain features of the FSP-851, FSP-851T and FAPT-851 may be available on
some control panels, but not on others. The possible features available in the
FSP-851, FSP-851T and FAPT-851, 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 con-
trolled independent of the LEDs.
Please refer to the operation manual for the UL listed control unit for specific
operation of the FSP-851, FSP-851T and FAPT-851.
The FSP-851, FSP-851T and FAPT-851 require compatible addressable com-
munications to function properly. Connect these sensors to listed-compatible
control panels only.
SPACING
Notifier recommends spacing sensors in compliance with NFPA 72. In low air
flow applications with smooth ceilings, space sensors 30 feet apart. When us-
ing the FAPT-851 as a heat detector in FM3210 compliant applications, space
sensors 20 feet apart. For specific information regarding sensor spacing, place-
ment, and special applications, refer to NFPA 72 or the System Smoke Detec-
tor Application Guide, available from Notifier.
Duct Applications: FSP-851 and FSP-851T are listed for use in ducts.
See Duct Applications Guide A05-1004 for details on pendant mount applications.
NOTE:
FSP-851 is listed for use inside DNR(W) duct smoke detectors.
WIRING GUIDE
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. Im-
proper connections will prevent a system from responding properly in the
event of a fire.

Remove power from the communication line before installing sensors.
1. Wire the sensor base (supplied separately) per the wiring diagram, Figure 1.
2. Set the desired address on the sensor address switches, see 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 communication 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 ship-
ping. Dust covers must be removed before the sensors can sense smoke. Remove
sensors prior to heavy remodeling or construction.

TAMPER-RESISTANCE
Models FSP-851, FSP-851T and FAPT-851 include a tamper-resistant capability
that prevents their removal from the bracket without the use of a tool. Refer to
the base manual for details on making use of this capability.
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. Test-
ing 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 mag-
net electronically simulates smoke in the sensing chamber, testing the
sensor electronics and connections to the control panel.
