GENERAL DESCRIPTION

Models FSP-951 and FSP-951-IV are plug-in type smoke sensors that combine

a photoelectronic sensing chamber with addressable-analog communications.

The sensors transmit an analog representation of smoke density over a com-

munication line to a control panel. Rotary dial switches are provided for set-

ting the sensor’s address. (See Figure 1.)

FIGURE 1. ROTARY ADDRESS SWITCHES:

TENS ONES

C0162-00

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 RA100Z).

Notifier panels offer different features sets across different models. As a result,

certain features of the photoelectric sensors may be available on some con-

trol panels, but not on others. FSP-951 will support only FlashScan® protocol

mode. FSP-951-IV will support either FlashScan or CLIP (Classic Loop Inter-

face Protocol) mode. The possible features available in the photoelectric sen-

sors, if supported by the control panel are:

1. The sensor’s LEDs can operate in three ways—on, off, and blinking–and

they can be set to red, green, or amber. This is controlled by the panel.

2. The remote output may be synchronized to the LED operation or con-

trolled independent of the LEDs.

3. Devices are point addressable up to 159 addresses.

Please refer to the operation manual for the UL listed control panel for specific

operation. The photoelectric sensors 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 (9.1 m).

For specific information regarding sensor spacing, placement, and special ap-

plications, refer to NFPA 72 or the System Smoke Detector Application Guide,

available from Notifier.

Duct Applications: FSP-951 and FSP-951-IV are listed for use in ducts. See

The FSP-951 and FSP-951-IV are intelligent photoelectric smoke sensors designed for use in fire alarm systems. These plug-in type sensors combine a photoelectronic sensing chamber with addressable-analog communications, allowing them to transmit an analog representation of smoke density over a communication line to a control panel. They are UL 268 listed for Open Air Protection and UL268A listed for Duct Applications, and are also suitable for use inside DNR(W) duct smoke detectors.

Function Description:

The primary function of these sensors is to detect smoke. When smoke enters the sensing chamber, the sensor transmits an analog signal to a compatible control panel, indicating the smoke density. This allows the panel to monitor for potential fire conditions. The sensors are equipped with rotary dial switches for setting their unique address, supporting up to 159 addresses. Two LEDs on the sensor provide visual status indications, controlled by the control panel. These LEDs can operate in three ways (on, off, or blinking) and can be set to red, green, or amber, depending on the panel's capabilities. An output is also provided for connecting an optional remote LED annunciator (P/N RA100Z), which can be synchronized with the sensor's LED operation or controlled independently.

The FSP-951 model supports only FlashScan® protocol mode, while the FSP-951-IV supports both FlashScan and CLIP (Classic Loop Interface Protocol) modes. These sensors require compatible addressable communications to function properly and must be connected to listed-compatible control panels only.

Usage Features:

Installation: Sensors must be installed in compliance with the control panel system installation manual, the National Electrical Code, applicable local codes, and any special requirements of the Authority Having Jurisdiction (AHJ). Proper wire gauges and color-coded wires should be used to minimize mistakes and ease troubleshooting. Power must be removed from the communication line before installation.
1. Wire the sensor base (supplied separately) as shown in the wiring diagram.
2. Set the desired address using the rotary dial switches.
3. Install the sensor into the sensor base by pushing it in and turning clockwise to secure it.
4. After installation, apply power to the control panel and activate the communication line.
Spacing: Notifier recommends spacing sensors in compliance with NFPA 72. For low air flow applications with smooth ceilings, sensors should be spaced 30 feet apart (9.1 m). For specific information on sensor spacing, placement, and special applications, refer to NFPA 72 or the System Smoke Detector Application Guide.
Tamper-Resistance: The sensors include a tamper-resistant capability that prevents removal from the base without a tool. Details on using this feature are provided in the base manual.
Duct Applications: The FSP-951 and FSP-951-IV are listed for use in ducts. Refer to the Duct Smoke Detectors Applications Guide HVAG53 for details on pendant mount applications. They are also listed for use inside DNR(W) duct smoke detectors.

Maintenance Features:

Testing: All sensors must be tested after installation and periodically thereafter, following methods approved by the AHJ and NFPA 72. Before testing, notify proper authorities and disable the system to prevent unwanted alarms.
- Functional (Magnet) Test: A test magnet (P/N M02-04-01 or M02-09-00) can be used to electronically simulate smoke in the sensing chamber, testing the sensor electronics and connections to the control panel. Hold the magnet in the designated magnet test area, and the sensor should alarm the panel. The panel controls the sensor LEDs, which can blink, latch on, or latch off, with specific operations detailed in the control panel's technical documentation.
- Smoke Entry Test: Sensitivity readings are available through the FACP. Canned aerosol simulated smoke (canned smoke agent) can also be used for smoke entry testing. Approved products include HSI Fire and Safety 25S, 30S (PURCHECK); SDi SMOKE CENTURIAN, SOLOA4, SMOKESABRE, TRUTEST; and TESTIFIRE 2000. When used properly, these agents will cause the smoke detector to go into alarm.
Cleaning: If a sensor fails any test, it may need cleaning. Before cleaning, notify proper authorities and disable the system.
1. Remove the sensor from the system.
2. Remove the sensor cover by pressing firmly on the four removal tabs.
3. Vacuum the screen carefully without removing it.
4. If further cleaning is needed, remove the chamber cover/screen assembly by pulling it straight out.
5. Use a vacuum cleaner or 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 and turning until it is firmly in place.
7. Replace the cover, aligning with the LEDs and gently pushing until it locks into place.
8. Reinstall the detector.
9. Test the detector as described in the TESTING section.
10. Reconnect disabled circuits.
11. Notify the proper authorities that the system is back on line.
Dust Covers: Dust covers provide limited protection during shipping but must be removed before sensors can detect smoke. Sensors should be removed prior to heavy remodeling or construction.

Important Considerations:

Smoke detectors should not be used with detector guards unless the combination has been evaluated and found suitable for that purpose.
Canned aerosol simulated smoke formulas vary by manufacturer. Misuse or overuse may have long-term adverse effects on the smoke detector. Always consult the manufacturer's instructions for warnings or caution statements.
