2.0 Installation Detector Dimensions The D381 detector is supplied with powder coated Aluminum enclosure. The enclosure has (4) 7mm holes in the rear mounting flange (Figure 1) that can be used to mount the detector directly on a flat surface or onto the optional swivel mounting bracket that allows the detector adjustment in vertical and horizontal 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 with no obstruction of the Field‐of‐View. 2.2.2 Using Swivel Mounting Bracket – This method will allow the detector to be adjusted in vertical and horizontal axis for optimum orientation. First, secure the Swivel Mount to the surface to be mounted. Next attach the detector onto the swivel mounting bracket using bolts supplied. 2.2.3 Direct Mounting. ‐ The detector may also be mounted directly to a flat surface using the (4) 7 ... -

Page 10: Operation And Startup
4.0 Operation & Start‐Up Detector Performance & Response The D381 is a Multi‐Spectrum UV/IR/IR medium range flame detector optimized for use in variety of indoor/outdoor applications in Class I, Division 2 area installations the detector includes a highly sensitive UV sensor and 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 will respond to both Hydrocarbon and Non‐Hydrocarbon within 3‐5 seconds, the response time will depend on the size of the flame, type of fuel, and the distance from the flame. Detector Operation Once powered up, the D381 detector will go through its self‐diagnostics process and will be ready for operation after 10‐12 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 UV and 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 D381 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: 4.3.1 During the normal operation and with no Alarm or 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 output configuration with power applied: ... -
Page 11: Alarm Condition
Alarm Condition: 4.3.2 When the D381 detector is exposed to fires and declares an Alarm, the following conditions will occur (with standard factory configurations): Red Alarm LED Will turn “ON” steady Green LED Will continue flashing “ON” and “OFF” Alarm relay Will be activated Auxiliary relay Will be activated Fault relay Will remain unchanged Analog output 20.0 +/‐ 0.2 mA ModBus output Will declare “Alarm” command Please note that the Red Alarm LED will remain “ON” and the Alarm relay will remain Energized as long the fire is present. Once the fire has been extinguished the detector status will be as follows: a) Non‐Latching Alarm Relay mode: The detector will automatically reset itself by De‐ Energizing the Alarm and Auxiliary Relays, turning off the Red LED, switching the analog output to 4 mA and removing the Alarm command from ModBus output b) Latching Alarm Relay mode: The detector status will remain unchanged with Alarm and Auxiliary relays still Energized and the Red Alarm LED remaining “ON” until the detector is ... -
Page 12: Detector Optical Path Test
a) Non‐Latching Fault Relay mode: 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: 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 recycling the 24 VDC power to detector momentarily. Detector Automatic Self‐Test: 4.3.4 The D381 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 several seconds indicating the self‐test process. During the self‐ test process, the detector will turn on its internal UV and IR test sources momentarily which will be reflected from the Sapphire window back into the UV and IR sensors for analysis. Following the automatic Self‐Test, the detector will return to Normal Operation if no Fault was detected. Detector Optical Path Test: 4.3.5 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 within 1” of detector’s 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. 5.0 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 working and trouble free: 5.1.1 The D381 detector requires no field calibration or adjustment. ... -
Page 13: Manual Test
5.2.2 Manual Test: In addition to the continuous Automatic Self‐Test, the D381 detectors can be tested manually on a periodic basis. Referring to Fig. 3, Detector Wiring Schematic, the manual test can be initiated by momentarily connecting wire Blue/Black (Test) to 24 VDC (return) of power supply. To facilitate the manual test, A momentary pushbutton switch can be installed and located at the Fire Alarm panel or Control Center. 6.0 D381 Detector Response Characteristics Performance Testing The D381 detector, like any other flame detectors, will respond to various types of fires differently both in time and distance. For this reason, the Factory Mutual (FM) baseline performance testing is performed for all flame detectors using 1ft. x 1ft. n‐Heptane pan fire for fuel fires and 30”‐36” high plume fire for gas flames. This procedure would allow the end‐users a means of comparing the flame detectors of various manufacturers for response time and sensitivity. Below is the response characteristic of the D381 detector as tested and witnessed by FM: Table 2 – D381 Detector Response @ High Sensitivity ‐ Indoor Fuel Type Flame Size Distance Response (ft / m) Seconds (Average) n‐Heptane 2” Dia. 11.75 / 3.6 ... - Page 14 Table 4 – D381 Detector Response in the Presence of False Alarm Source False Alarm Source Fire Size and Distance Unmodulated Modulate Fuel (ft./m) Response Time Response Time Seconds (Ave.) Seconds (Ave.) Sunlight 12”x 12” n‐Heptane 80/24.4 5.7 2.5 Incandescent Lamp – 60W 2” Dia. n‐Heptane 9.75/2.97 2.7 3.3 Infrared Heater – 1500W 2” Dia. n‐Heptane 9.75/2.97 2.5 2.3 Sodium Vapor Lamp 2” Dia. n‐Heptane 9.75/2.97 3.9 1.6 Florescent Lamp 2” Dia. n‐Heptane 9.75/2.97 3.8 3.0 ...
