1 INTRODUCTION 1.1 Overview The SharpEye 40/40I is a flame detector that utilizes improved IR3 technology to provide state-of-the-art fire protection. The 40/40I uses patented digital signal processing to analyze the spectral and dynamic characteristics of the infrared radiation, to identify fire events with exceptional sensitivity and extreme immunity to false alarms. All 40/40 series detectors include a heated optical window for improved performance in icing, snow and condensation conditions.

The heated optics can be set to one of the following: • Not operated • On continuously • Automatic, per temperature change (default): you can define the start temperature below which the window is heated. (The default is 68°F (20°C).) This temperature can be defined between 32°F (0°C) to 122°F (50°C). The heating stops when the temperature is 27°F (15°C) above the start temperature. For more information, see Configuring your Detector on page 29. 1.4.
1.4.5.3 SIL-2 Approved The 40/40I Flame Detector is certified to SIL-2 requirement per IEC 61508.4, Chapter 3.5.12. The alert condition according to SIL-2 can be implemented by: • Alert signal via 0-20mA current loop. or • Alert signal via alarm relay and fault relay. • For more details and guidelines for configuring, installing, operating and service – see SIL-2 Features on page 48 and TÜV Report No. 968/EZ326.00/008. 1.4.5.4 EN54-10 The 40/40I Flame Detector is certified to EN54-10 and CPD.
1.5.1.3 Other Fuels The detector reacts to other types of fire as follows: 2 2 • The baseline fire refers to n-heptane 1ft (0.1m ) and is defined as 100% sensitivity. 2 2 • For fuel fire – standard pan fire size: 1 ft (0.1 m ). • For gas flame - 20 inch (0.5m) high, 8 inch (0.2m) width plume fire. • Maximum Response Time: 10 sec.

1.6 Internal Detector Tests The detector performs two types of self tests: • Continuous Feature Test, page 19 • Built-In-Test (BIT), page 19 1.6.1 Continuous Feature Test During normal operation, the detector tests itself continuously and indicates a fault if a failure is found. This type of test complies with SIL-2 requirements.
1.6.2.1 How the BIT Operates • The detector's status remains unchanged if the result of a BIT is the same as the current status (NORMAL or BIT Fault) • the detectors’ status is changed (from Normal to BIT Fault or vice versa) if the BIT differs from the current status Note: In ‘BIT Fault’ status the detector can continue to detect a fire. 1.6.2.2 Automatic BIT The detector automatically performs a BIT every 15 minutes. A successful BIT sequence does not activate any indicator.

• Environment: • Dust, snow or rain can reduce the detectors sensitivity and require more maintenance activities. • The presence of high intensity flickering IR sources may affect sensitivity. • Aiming the Detector: • The detector should be aimed toward the center of the detection zone and have a completely unobstructed view of the protected area. • Whenever possible, the detector face should be tilted down at a 45º angle to maximize coverage and prevent accumulation of dust and dirt.
2.4 Certification Instructions Warning: Do not open the detector, even when isolated, when flammable atmosphere present. Use the following certification instructions: • The cable entry point may exceed 167°F (75°C). Suitable precautions should be taken when selecting the cable. • The equipment may be used with flammable gases and vapors with apparatus groups IIA and IIB + H2: • T5 in the ambient temperature range: –67°F (–55°C) to +167°F (+75°C).
• • • • 2.6 When using the optional tilt mount, use flexible conduits for the last portion connecting to the detector. For installations in atmospheres as defined in group B of the NFPA 72E, seal the conduits inlets. When pulling the cables through the conduits, ensure that they are not tangled or stressed. Extend the cables about 30 cm. (12 in.) beyond the detector location to accommodate wiring after installation.

Note: Removing the detector for maintenance purpose does not require the Tilt Mount to be removed). 12 Unpack the detector.
2.7 Connecting the Detector This section describes how to connect the electric cabling to the detector (Figure 7). Ø To connect the detector to the electrical cables 15 16 17 18 Disconnect the power. Remove the back cover of the detector by removing four (4) socket head-screws in the cover bolts. The terminal chamber is now revealed. Remove the protective plug mounted on the Detector Conduit/Cable entry; pull the wires through the Detector Inlet.
2.7.1 Verifying the Detector Wiring The detector has five output wiring options within the EExde integral terminal section of the enclosure. There are 12 terminals labeled 1-12. Table 17 describes the function of each terminal for all the wiring options. Table 17: Model 40/40I Wiring Options Wire Terminal No.
2.8 Configuring your Detector You can reprogram the function setup using the RS-485 connection or using the Hart Protocol as follows: • Industrial Scientific Host Software : The Industrial Scientific Host Software is for use on a PC or laptop. Refer to Manual TM777050 for programming instructions. The Host software enables you to change the functions. • Handheld Unit: Refer to Manual 777060 for programming instructions when using the Handheld Unit.
2.8.2 Alarm Delay The detector is equipped with an Alarm Delay option, which provides programmable time delays with settings at: • Antiflare* (default) *The Antiflare mode is selected to prevent false alarms in locations where fast flares may be present. The Time Delay for fire alarms in this mode ranges from 2.5 to 15 seconds (usually, less than 10 seconds).
2.8.5 Heated Optics The heated optics can be defined as one of the following modes: • Heated Mode • OFF: Not operated • On: Continuously • AUTO: Per temperature change In AUTO mode, the default HEAT ON setting is 68°F (20°C). Heating stops when the temperature is 27°F (15°C) above the start temperature. You can define the start temperature below which the window will be heated. The temperature can be defined between 32°F and 122°F (0°C to 50°C).
3.2.1 • You should only access the wiring compartment to wire or remove the detector or access RS485 terminals for maintenance. • Disconnect or disable external devices, such as automatic extinguishing systems before carrying out any maintenance. Default Functions Settings Table 20 lists the default function configuration supplied with the detector.
3.3.1 Automatic BIT Test Check that the indicators show normal conditions. See Powering Up on page 31. 3.3.2 Manual BIT Test Important: If the function setup Alarm BIT and/or Auxiliary BIT are set to Yes (default No), the Alarm, Auxiliary Relay and 0-20mA outputs are activated during a Manual BIT. Therefore, automatic extinguishing systems or any external devices that may be activated during BIT must be disconnected. Ø To perform a Manual BIT: 27 28 3.3.3 Verify that the detector is Normal Mode.
4 MAINTENANCE AND TROUBLESHOOTING This chapter deals with preventive maintenance, describes possible faults in detector operation and indicates corrective measures. Ignoring these instructions may cause problems with the detector and may invalidate the warranty. Whenever a unit requires service, please contact Industrial Scientific or its authorized distributor for assistance. 4.
4.1.3 Keeping Maintenance Records It is recommended that maintenance operations performed on a detector are recorded in a Log-book. The record should include the following: • Installation date, and contractor • Serial and tag no. • Entries for every maintenance operation performed, including the description of the operation, date and personnel ID. If a unit is sent to Industrial Scientific or a distributor for service, a copy of the maintenance records should accompany it. 4.
