FS24X-211-21-1 FS24X QuadBand™ IR3+ Fire and Flame Detector, Copper-Free Aluminum Encl., (2) 3/4 in. NPT entries FM & ATEX approved by Honeywell Analytics

Fire Sentry FS24X is a quantum leap in flame detection with its sophisticated software and detection technology.

The Fire Sentry FS24X is the latest generation high technology Multi-Spectrum Triple IR (IR/IR/IR/Visible) Flame Detector, which is part of our FSX family of advanced technology Electro-Optical fire detectors. Using our patented* WideBand IR™, WideBand 4.3 micron IR™, and Visible detection technology, the Fire Sentry FS24X is a quantum leap in flame detection. Sophisticated software algorithms and dual microprocessors ensure that the Fire Sentry FS24X has the highest flame detection performance combined with optimal false alarm rejection.

The WideBand IR™ Infrared technology using high-speed solid-state Quantum sensors allows detection of all types of fires, hydrocarbon and non-hydrocarbon, in all weather conditions. If the detector's signal is blocked by ordinary window glass, the patented WideBand IR sensors will still alarm to the fire albeit at a reduced sensitivity and slower response time.

Dual microprocessors provide a high level of fail-safe operation combined with fast and reliable performance. The master microprocessor performs high-speed digital sampling and signal-processing calculations, while the slave microprocessor handles various sensor data, performs communications, self-diagnostics and provides interface versatility and additional memory for storing Event Log and FirePic™ data.

The Fire Sentry FSX family of detectors feature our patented* FirePic data storage and information retrieval facility. FirePic™ records pre-fire data, which can be recovered from the Detector's non-volatile flash memory for post fire analysis and postulation of the fire cause. Additionally, unique Real-Time Graphing (RTG™) allows viewing of the data which the Detector actually sees. A combination of outputs makes the Fire Sentry FS24X a truly versatile detector for today's demanding industrial requirements.

The Fire Sentry FS24X detector has a detection range greater than 200 feet (Very High Sensitivity setting) for the detection of a one square-foot Heptane reference fire and has a cone of vision far greater in volumetric coverage than any other Multi-Spectrum IR Detector. This means fewer Detectors can be used as compared to other manufacturers' Detectors.

0635 9532 Vane Probe (Ø 16 mm) Fixed Cable by Testo

Use the vane probe with the compatible testo multifunction measuring instrument (please order separately) to determine air velocity and volume flow.

Vane probe - features

Use the fixed cable to connect the vane probe to the measuring instrument. The probe is equipped with a telescope, which can be extended to a maximum length of 0.85 m. The immersion depth is easy to read off thanks to the scaling on the telescope.

The clearly structured measurement menu for volume flow makes the measuring instrument intuitive to operate.

You will get exceptionally accurate measurement results with the digital probe, because the measuring instrument makes measurement uncertainty a thing of the past. You only need to send the probe in for calibration - so the measuring instrument remains in continuous use.

Areas of application for the hot wire probe

Ventilation ducts: Use the vane probe to measure air velocity in ventilation ducts with reliability. Benefit from fast calculation of the volume flow: in the "volume flow" measurement menu of the compatible measuring instrument (please order separately), configure the dimensions and geometry of the duct cross-section - the measuring instrument shows you the volume flow straight away.

• Intuitive: parallel determination of air velocity, volume flow and humidity

30-0954RK-225 Aspirator Panel for One IR Direct Connect or S2 Transmitter, with Flow Switch by RKI Instruments

Single or dual sensor system is designed to monitor gas atmospheres from extreme conditions with either temperature, moisture, or pressure challenges. A powerful air aspirator can pull a sample from up to 100 feet away. The filtered and conditioned sample gas is then passed across one or two different detectors. Each detector shares a common calibration and compressed air inlet for aspirated flow. This system is fault tolerant removing the need for expensive downtime and maintenance. The sample is diluted with air after the gas sensor and then returned to a common exhaust reducing the danger of potential hazardous gases entering a safe work space.

System integrity is maintained at all times using a flow fail monitoring device which provides a NO contact that activates if the sample line becomes blocked or damaged or if the air supply is removed or interrupted.

The panel can be used with direct-connect (sensors connected to an RKI controller), or with S2 Series, and M2 Series transmitters. All transmitters have a 4-20 mA signal for direct connection to the site DCS, PLC or site control system. If needed, RKI instruments can supply a dedicated Gas Detection Control system to provide local alarms, 4-20 mA output with a wide range of dry contacts, making the system very sophisticated and user friendly.

Integral sample filter included to remove water and dirt, automatic drain type.

RS485 Modbus output options available on the M2 transmitter.

SS4-AS2 Multi-Spectrum Electro-Optical Digital Fire & Flame Detector, Aluminum UV/IR, FM, optimised for Non-Hydrocarbons and Silane, Ethanol, Methanol, Hydrogen & Natural Gas Fires, Non-latching Alarm LED, FM, cFM, CSFM for Class I, Div.1 groups B,C & D (2) 3/4 NPT by Honeywell Analytics

The Fire Sentry SS4 Electro-Optical Digital Fire and Flame Detectors represent leading edge UV and UV/IR technology.

Fire Sentry SS4-A

The Fire Sentry SS4-A represents the world's pre-eminent UV/IR technology for ElectroOptical Flame Detectors with tens of thousands successfully operating in a multitude of installations worldwide. This multi-spectrum detector senses radiant energy in the ultraviolet (UV), visible and wide band Infrared™ (IR) spectrum. The radiant energy from all types of flaming fires will alert the detector to their presence.

To eliminate common nuisance false alarms that occasionally occur with UV-only, IR-only, Dual IR or Dual Mode UV/IR detectors, the Fire Sentry SS4 detectors' FireLogic signal processing requires that UV, visible and wide band IR radiant energy all be evaluated before declaring a fire. The smart detector utilises real-time signal processing algorithms that are optimised to alarm on all types of fires, while virtually eliminating the possibility of false alarms.

Fire Sentry SS4-AS

The Fire Sentry SS4-AS processes UV, IR and Visible (VIS) spectral ranges from ruggedised solar-blind UV, "Quantum-Effect" IR and VIS sensors correspondingly. It is optimised for detection of hydrogen, ethanol, methanol and methane (natural gas) fires and like the other detectors in its family, it responds to Type A, B and C flaming fires.

Fire Sentry SS4-AUV

The Fire Sentry SS4-AUV represents the leading edge technology UV optical flame detectors. This flame detector senses radiant energy in the ultraviolet (UV) spectrum. The radiant emissions of flaming fires will alert the detector to their presence. The SS4-AUV is for indoor applications where UV sources such as welding are not present.

Operation

The Fire Sentry SS4 detectors operate from standard 24 Volt DC power and interface to approved fire alarm panels or standard PLC's. On power up, a self-test is performed and the fault relay resets to show no faults. The front LED lights flash every ten seconds to indicate power is on.

The continuous spectral data stream of information from the sensor array is analysed by the microprocessor. Upon alarm, the detector activates the alarm relay and stores all the pre-fire spectral data in non-volatile memory for retrieval and evaluation. This Fire Pic™ data can be used to postulate the cause of the fire. As part of the FS2000™ System, the SS4 family of detectors communicate with CM1-A Controller via a four wire bi-directional RS-485 FireBus™.

The field of view for the Fire Sentry SS4 detectors is the widest in the industry with a 120° cone of vision. This means more hazard area can be covered by each detector. Greater sensitivity also increases the volume covered by each detector; up to four times more than some other detectors.

Using sophisticated microprocessor signal processing algorithms, false alarm rejection is maximised - with virtual immunity to false alarms from arc welding, corona discharge and other common non-fire sources.
