Notifier FSI-851 User manual

FSI-851 Plug-in Intelligent Ionization Sensor
Installation and Maintenance Instructions
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 FSI-851 is an intelligent sensor that uses a state-of-the-art sensing chamber. This sensor is designed to provide open area protection and is intend-
ed for use with compatible control panels only.
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 feature sets across different models.As a result, certain features of the FSI-851 may be available on some control panels, but
not on others. The sensor will support either FlashScan™ or CLIP (Classic Loop Interface Protocol) mode. The possible features available in the FSI-851,
if supported by the control unit include:
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 FSI-851.
The FSI-851 requires compatible addressable communications to function properly. Connect this sensor 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. For specific information
regarding sensor spacing, placement, and special applica-
tions, refer to NFPA 72 or the System Smoke Detector
Application Guide, available from Notifier.
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. Improper connections will prevent a sys-
tem 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, see Figure 1.
2. Set the desired address on the sensor address switches, see Figure 2.
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 finger
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 communication line.
5. Test the sensor(s) as described in the TESTING section of this manual.
Dust covers provide limited protection against airborne dust particles during shipment. Dust covers must be removed before the sensors can
sense smoke. Remove the sensors prior to heavy remodeling or construction.
TAMPER-RESISTANCE
Model FSI-851 includes a tamper-resistant capability that prevents its 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. Testing
methods must satisfy the Authority Having
Jurisdiction (AHJ). Sensors offer maximum performance when tested and
maintained in compliance with NFPA 72.
Test the sensor as follows:
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
electronics and connections to the control panel.
1. Hold the test magnet in the magnet test area as shown in Figure 3.
2. The sensor should alarm the panel.
Two LEDs on the sensor are controlled by the panel to indicate sensor sta-
tus. 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.
When testing is complete, restore the system to normal operation and notify the
proper authorities that the system is back in operation.
CLEANING
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 sensor to be cleaned from the system.
2. Remove the sensor cover. Press firmly on each of the four removal tabs that
hold the cover in place.
3. Vacuum the outside of the screen carefully without removing it. If further
cleaning is required continue with Step 4, otherwise skip to Step 7.
4. Remove the chamber cover/screen assembly by pulling it straight out.
5. Use a vacuum cleaner or clean, compressed air to remove dust and debris
from the sensing chamber.
6. Reinstall the chamber cover/screen assembly by sliding the edge over the
sensing chamber. Turn until it is firmly inplace.
7. Replace the cover using the LEDs to align the cover and then gently push-
ing 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.
