Incorporated in an Argus fire control system the Argus infrared detector will detect, react and extinguish the threat, before it can cause extensive damage to the machinery or process in which it is installed. Taking advantage of the latest in high-speed detector sensor technology allows the Argus infrared detector to perform these tasks. The detector cell is capable of detecting an ember, spark or fire in less than one-half microsecond. This speed allows several advantages to be realized in the overall detector unit design, not the least of which is discrimination, or the ability to determine whether or not the ember or spark fits a velocity profile that would be produced by the material flow in a duct or chute. The design incorporates this capability and continually monitors the duct for embers, sparks or fire, that meet the qualifications of a particular velocity/intensity pro'file. This feature considerably reduces the risk of false alarm due to electrical noise present in all industrial environments. In addition to velocity/intensity profile monitoring, the detector incorporates an ambient light filter to reduce the sensitivity of the system to ambient or background lighting in the visible region of the spectrum, while allowing radiation in the infrared region to be detected essentially un-attenuated. The detectors are designed to "latch" or lock into alarm when an ember, spark or fire is visible to the detector cell. Once the detector is in alarm, it can only be reset by the control panel or by removing power from it. NOTE: The Argus 243 PULSE series of detectors DO NOT latch into alarm. The recommended application is for detection in dark or semi-dark areas with less than 10 foot candles (108 lux) ambient illumination. If properly located at the sides, or top of a duct, the detector design effectively eliminates the buildup of dust on the lens. Normally, the detector is mounted flush with the duct wall, so the air traveling through the ducts tend to clean the lens surface. CAUTION: Direct or indirect exposure to ambient light could cause the detector to go into alarm, causing the system to discharge the extinguishing agent. CAUTION: If tint, dye, or other materials are added to the process, and they coat the interior of the duct, the detector lens would require periodic cleaning (refer to maintenance section for details). ........ 2301 Distribution Street Part #: ARGD00059 Charlotte, NC 28203 USA Issued: June 20, 2000 Phone 704-372-1228 Revised: June 12, 2002 Fax 704-377-6131 Page 1 e-mail: [email protected] ARGUS INFRARED DETECTOR Installation, Operation ARGUS SERIES 242, 243 & 343 and Maintenance Manual FIRE CONTROL The silicon photo-voltaic cell and printed circuit board of the detectors are mounted in a steel housing 4-3/8 inch x 4-3/8 inch x 2-1/4 inch (110 X 110 X 60mm) with a cover, and holes for mounting. Three holes are required in the wall of the duct to accommodate the mounting hardware and the detector lens. The region of detector sensitivity is between the limits of 750 nanometers and 1250 nanometers, with peak sensitivity at 950 nanometers. The visible portion of the spectrum lies between the limits of 450 and 750 nanometers. Thus, the detector is -. basically less sensitive to light in the visible portion of the spectrum. The internal circuitry in the Argus detector is 100% solid-state and is designed to accept signals from the sensor which meet a fairly wide velocity/intensity profile such as would allow detection of any signal which might appear in the material flow which could cause combustion. The Argus 343 infrared spark detector adds to this detection technology by adding a Peripheral Interface Controller (PIC) to the detector's circuitry. This enables the Argus Odyssey 'fire control system to assign each detector a specific idenhfication designation and allows the Argus Odyssey fire control system to determine which detector is either in trouble or alarm. The PIC integrated in the 343 detector, permits the Argus Odyssey fire control system to automatically test all the detectors connected to the Odyssey Panel. During this testing any failures or troubles will be reported back to the Odyssey monitor panel. The 242 and 243 infrared detectors can also be up-graded so that they may be used in the Odyssey fire control system. Installing a PIC Adapter (P/N ARG-ODP1) device to the detector does this. NOTE: When using any detector with the Odyssey fire control system a test light assembly (P/N ARGD001 01 *) must be installed with each group of detectors to perform self-testing functions.
