1.0 General

The Argus Infrared Detectors (Series 242, 243 and 343) are highly sensitive, fast-acting detection units designed to detect an ember or fire in its incipient stage. 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).

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.

3.2.4 Recommended Spacing On Material Transfer Conveyors:

Refer to Figure 3.7 for a diagram of the recommended spacing of detectors for protecting a conveyor belt. For a conveyor less than 48" (1200mm) wide, two detectors shall be placed 18" (450mm) to 36" (900rnm) above the surface of the conveyor. The detectors shall not be more then 24" (600mm) apart from each other and spaced so that detectors cone of vision (90 degrees) overlaps the material being transported on the conveyor.

NOTE: It may be necessary to construct a hood or cover over the conveyor to keep the light level below the allowable limit of the detectors (10 foot candles), otherwise the system may experience unwanted alarms.

For conveyors wider than 48" (1200mm) additional detectors must be used to protect the material being transported by the conveyor.

3.3 WIRING

All wiring from control panel to the Argus Infrared detectors shall be 16 AWG (1.4mm) and shall be run in it's own steel (flexible or rigid) conduit. Recommended wire colors can be found in Table 3.3.

Table 3.3 Recommended Wire Colors

TERMINAL FUNCTION WIRE COLOR 1 Negative (Return) Black 2 Signal White 3 Positive Red 4 Annunciator Orange

GND Ground Green

NOTE: The annunciator wire is only required when the detector is being connected to either the Odyssey Fire Control system or an annunciator panel.

Each zone of detectors (refer to specific control panel manual for allowable number of detectors per zone) is connected in series to the control panel. With the control panel and detectors properly located and all power removed, pull the required wires through the appropriate sized conduit and terminate the wire at the proper detector. Leave extra wire at both ends to allow for connecting the wires to the device.

CAUTION: Do not twist together leads or use continuous wire to connect detectors in series. Wires must terminate and begin from each detector's terminal strip. Failure do so could result in system malfunction or unreported trouble signals. Refer to Figure 3.8

3.3.1 Annunciator Wiring For 242 and 243 Detectors:

The annunciator of the Argus 242 or 243 detectors provides a 24-volt DC signal back to an annunciator panel to indicate which detector has gone into alarm. In this application each detector will have it's own dedicated annunciator lead. (Refer to Figure 3.9). Therefore, when sizing conduit the number of wires will increase with each detector going back to the panel. Each annunciator lead should be marked as to what detector it is connected to. If an annunciator panel is not being utilized then the annunciator terminal will not be used.

CAUTION: When the Argus 242 or 243 detectors are used in the Odyssey Fire Control System, a PIC adaptor must be installed on each detector and the annunciator wire is to be wired in series as described in section 3.3.2. Failure to do so will damage to the Odyssey Fire Control system.

3.3.2 Detector Annunciator Wiring For Odyssey Fire Control Systems:

When connecting the detectors to the Odyssey Fire Control System the function of annunciator lead is different than non-Odyssey systems, in that the return voltage is not a 24 volt DC signal, but a voltage that identifies the detector to the control panel.

Each detector of a zone is wired in series (daisy chain fashion) to that zone's panel connection, therefore there will only be one (1) annunciator wire per zone.

Argus 343 detectors do not require any additional adapters except for the end-of-line module on the last detector of that zone string (See Figure 3.10). Argus 242 and 243 detectors, in addition to the End-of-Line Module, require a PIC Adapter (PIN ARG ODP1) with each 242 or 243 detector. Refer to Figure 3.11 for wiring details.

4.0 MAINTENANCE:

CAUTION: DIRECT OR INDIRECT EXPOSURE TO AMBIENT LIGHT WILL CAUSE THE DETECTOR TO GO INTO ALARM. ALL HOLES (FOR TESTING) AND CRACKS MUST BE SEALED WITH THICK BLACK TAPE, OR OTHER SUITABLE MEANS SO AS TO NOT LET LIGHT INTO THE DUCT.

WARNING: PLACING THE DETECTORS INTO ALARM WILL CAUSE THE CONTROL PANEL TO GO INTO ALARM, DISCHARGE THE EXTINGUISHING AGENT AND SHUT DOWN THE PROCESS BEING PROTECTED. CONSULT WITH THE CONTROL PANEL MANUAL OR YOUR ARGUS REPRESENTATIVE AS TO THE BEST WAY TO DISABLE THE EXTINGUISHER AND SHUTDOWN CIRCUITS BEFORE TESTING DETECTORS.

The Argus Infrared Detector sensitivity is preset at the factory. Simple testing with an infrared test light and cleaning of the detector lens is all that should be required after installation. Argus strongly recommends that each detector be tested at a regular interval, such as, during monthly visual inspections. At no time should each detector go more than six (6) months without being ''test fired". Lenses should be checked and wiped cleaned periodically with a soft non-abrasive cloth. In applications where tints or dyes are used the lens should be inspected more frequently and cleaned as required.

The method for test firing each detector should be by placing each detector into alarm, thereby putting the control panel into alarm (See Warning). The recommended method of putting a detector into alarm is by placing a small hole (3mm or 14 inch) in the duct near each detector so that the Argus infrared test light (Part Number: ARGD00018) can be shined into the duct at each detector (See Caution). Once the detector is placed into alarm it should light the red LED on the detector and place the control panel into alarm, sounding a bell and lighting a strobe. If the red LED or control panel does not indicate an alarm status, further troubleshooting should be performed to determine the source of the problem. Consult with your Argus manuals andlor Argus representative if a solution is not readily obtainable. If the panel does not indicate alarm when signaled, then the fire protection system is not operating within specifications and the protected process must be shutdown.

The Argus Odyssey Fire Control System uses for each group of detectors a mounted 880-nanometer infrared test light (PIN - ARGD001 01 *) to automatically test the detectors. The testing can be programmed to occur at different intervals ranging from daily to weekly testing. If authorized or configured, the Odyssey system will allow manual testing of all detectors in the system by pushing a single switch. If any detector fails this system wide test it will be noted in the monitor panel and indicate to the user the location of the failed detector(s). Any detectors that are shown to have failed the test must be inspected for possible lens obstruction, wiring fault, or other malfunction. If the detector failure cannot be found or repaired the detector must be replaced.

NOTE: Consult with the Odyssey Fire Control System instruction manual or Argus Fire Control for additional details.

After a fire or alarm the detector lens must be inspected for damage. If the lens or the detector shows any signs of scorching or other damage the detector should be replaced. Note, since damage to detector may not be visible, Argus Fire Control highly recommends that a test of the detector be conducted. Also,

No internal maintenance is required unless the unit does not respond to the test light, in which case the unit should be replaced and returned to Argus Fire Control.
