Page 3: Introduction
1.0 Introduction Product Description The Multi‐Spectrum D390 is a stand‐alone 3IR flame detector designed specifically for installation in Semiconductor clean rooms and wet benches for fast detection of Hydrocarbon and Non‐Hydrocarbon based fires. The Model D390 senses the IR radiation in 3 discrete bands of Infrared in the range of 2‐5 microns. The Model D390 sensors and electronic circuit boards are enclosed in a sealed water‐tight Polypropylene enclosure rated IP67 making it an ideal detector for installing in harsh chemical laden environment. The detector can be used as a stand‐alone device or can be interfaced with any approved fire alarm panel. The detector will respond to one square‐foot n‐Heptane fire within 3‐5 seconds from of 30 feet. ... -

Page 5: Installation
2.0 Installation Detector Dimensions The D390 detector has (4) 6mm holes in the rear mounting flange (Figure 1) that can be used to mount the detector directly on a flat surface. The detector can also be mounted using an optional Polypropylene swivel mounting bracket (Figure 2) that allows the detector adjustment in vertical axis. Figure 1 – Detector Dimensions Mounting the Detector 2.2.1 Positioning ‐ The detector should be installed such that the center of the detector’s field‐of‐view is aimed directly at the center of the area to be protected (hazard area). Detectors should be installed above the hazard area pointing downward with no obstruction of the Field‐of‐View. 2.2.2 Direct Mounting. ‐ The detector may also be mounted directly to a flat surface using the (4) mounting hole on the rear mounting flange and secure it firmly with (4) stainless steel screws. 2.2.3 Installation Tips: ‐ When installing the detectors, be aware of the following conditions: ... -

Page 12: Operation And Startup
3.0 Operation & Startup Detector Performance & Response The D390 is a Multi‐Spectrum Infrared fire and flame detector designed for detection of Hydrocarbon and Non‐Hydrocarbon fires. The detector includes 3 separate Quantum IR sensors tuned precisely to 3 separate bands of IR radiation in the electromagnetic spectrum for responding to various types of fires. The detector electronics module assembly is encased in a sealed Polypropylene enclosure and is offered with an integral multi‐conductor cable with Teflon jacket suitable for using in harsh and chemical laden environment. Detector’s response to a flame is normally 3‐5 seconds and the response time will depend on the size of the flame and the distance from the flame. Detector Operation Once powered up, the D390 detector will go through its self‐diagnostics process and will be ready for operation after 10 seconds. During the self‐diagnostic process, the Green, Amber, and Red LEDs will turn on sequentially indicating this process. During the self‐diagnostics, the Microprocessor will check the status of IR sensors, relays, various devices, and the self‐test feature. Once the Microprocessor determines that all devices and functions have been tested and found to be within the specifications, it will then terminate the self‐test diagnostics and will return the detector to normal operation. During the normal operation, the Green LED will be turn “ON” for 1 second and “OFF” for 1 second indicating that the detector is now ready to detect fires. Detector Visual Status Indications The D390 detector has (3) bright LEDs for indicating the status of the detector: Green LED Normal operation RED LED Alarm condition Amber LED Fault condition Normal Operation: 3.3.1 During the normal operation, with no Alarm and no Fault existing, the detector will turn the Green LED “ON” for 1 second and “OFF” for 1 second indicating normal status. Unless otherwise specified the detector will be shipped with the following standard factory relay output ... -
Page 13: Fault Operation
Green LED Will continue flashing “ON” and “OFF” Fault relay Will be De‐Energized (deactivated) Analog output 2.0 +/‐0.2 mA Dirty window 0.3 – 0.9 mA Other Faults ModBus output “Fault” Command a) Non‐Latching Fault Relay mode (Factory default): When the Fault has been cleared, the detector will automatically reset itself by turning off the Amber LED and Energizing the Fault relay. b) Latching Fault Relay mode: When the Fault clears, the detector status will remain unchanged with Fault relay still De‐Energized and the Amber Fault LED remaining “ON” until the detector is reset by removing the 24 VDC power from detector momentarily. c) A Fault may occur if one or more of the following conditions exist (with standard factory configurations): Faulty Sensor (IR) Faulty Microprocessor Faulty Relay Damaged component Low input power (less than 18 VDC) High input power (higher than 32 VDC) High temperature Dirty viewing window MAN‐D390‐0001 13 ... -
Page 14: Detector Self-Test
Detector Self‐Test: 3.3.4 The D390 detector is programmed to perform an automatic diagnostic self‐test periodically (factory default is every 5 minutes). During the automatic Self‐Test, the detector will turn on both Amber LEDs flashing for 2‐3 seconds. Following the automatic Self‐Test, the detector will return to Normal Operation if no Fault was detected. Detector Optical Path Test: 3.3.5 The detector also monitors the cleanliness of its viewing window and blockage of its viewing window every second using the OptiRadar feature. If the contamination of the window exceeds the preset threshold, the detector will declare a Fault. The detector also monitors the blockage of the window by external objects. If an object is placed on the surface of the window, the detector will turn on its Amber light flashing for 60 seconds; and if the blockage is not removed after 60 seconds, the detector will declare a Fault by changing the flashing Amber light to steady on. 4.0 Maintenance Inspection and Cleaning Once the detector has been installed and powered up, it should provide maintenance free performance for years. The following is a simple guideline for keeping the detector functioning properly and trouble free: 4.1.1 The D390 detector required no field calibration or adjustment. 4.1.2 The detector is encased in a sealed Polypropylene enclosure requiring very little maintenance. However; in harsh chemical‐laden environment, dusty and oily places contaminant tend to ... -
