2.1 Principles Of Operation

20/20ML

The Model 20/20ML UV/IR Flame Detector is an electronic device designed to sense the occurrence of fire and flames and subsequently activate an alarm or an extinguishing system directly or through a control circuit.

The UV-IR Radiation Flame Detector is a dual spectrum optical detector sensitive to two separate ranges of the radiation spectrum, both of which are present in fires. The detector monitors the protected area, by measuring the radiation intensity in it, within two frequencies ranges of the electromagnetic spectrum, namely the Ultra-Violet (UV) and the Infra-Red (IR).

The detector integrates two dependent channels in which appropriate detection pulses are registered and further analyzed for frequency, intensity and duration.

20/20MU

The Model 20/20MU UV Flame Detector is an electronic device designed to sense the occurrence of fire and flames and subsequently activate an alarm or an extinguishing system directly or through a control circuit.

The UV Flame Detector is a single spectrum optical detector sensitive to the UV radiation spectrum, which is present in fires. The detector monitors the protected area, by measuring the radiation intensity and the frequency range of the electromagnetic spectrum, namely the UV.

The detector senses one channel in which appropriate detection pulses are registered and further analyzed for frequency, intensity and duration.

(0.1m2) fire.

Spectrex Inc. - SharpEyeTM ML & MU Flame Detector Manual – TM 767100, Rev. A, April 2005

2.2 Sensing Elements

20/20ML

The IR sensor is sensitive to radiation over the range of 2.5-3.0 micron. The IR channel will register a detection signal, at the appropriate level, when the

IR sensor is exposed to radiation in the appropriate frequency range, having an intermittent gleam pattern characteristic to flickering-fire, and when a preset threshold and time duration are reached.

The UV sensor is sensitive to radiation over the range of 0.185-0.260 micron. The UV channel incorporates a special logic circuit that eliminates false alarms caused by solar radiation and other non-fire UV sources. Furthermore, the UV channel sensitivity is stabilized over the working temperature range.

20/20MU

2.3 Modbus RS-485

For more advanced communication 20/20ML and 20/20MU has a RS 485 modbus Compatible output that provides Data communication from a network (up to 247 detectors) to a host computer on universal controller for central monitoring. This feature enables reconfiguration of factory settings, eases maintenance and allows local and remote diagnostics.

Spectrex Inc. - SharpEyeTM ML & MU Flame Detector Manual – TM 767100, Rev. A, April 2005

2.4 Types and Models

The 20/20ML and 20/20MU have two (2) housing options: St. St. 316L, and plastic. The output is via either a connector (socket) or a cable tail (up to 2m long).

3. Performance

3.1 Detection Sensitivity

Detection sensitivity is the maximum distance at which the detector will reliably detect a specific size of fire & typical type of fuel (standard fire).

Standard Fire:

(0.1m2) Gasoline pan fire with max. wind speed of 6.5 ft/sec (2 m/sec).

A 1ft

Sensitivity Ranges:

The detector has two user selectable sensitivity ranges. For each range there are two response levels.

1. WARNING (Pre-alarm)

2. ALARM

The detection distance, for the WARNING level, is approximately 10% higher than the ALARM distance. Alarm response times for a “standard fire” at a specified range are shown hereunder.

Sensitivity Range – ft (m) 50 (15) Response Time (sec) 5

For some typical ambient conditions the Zeta parameter as defined in NFPA 72 for the detector 20/20ML is 0.01 (1/meter) and 20/20MU is 0.0003 (1/meter).

Note:

Zeta parameters may vary significantly with changes in temp, air pressure, humidity, visibility conditions, etc.

Notes: 1 The alarm outputs will be activated as long as the alarm conditions are present 2 The Alarm state can be latched (optional) according to programmable function 3 The detector will be in its BIT FAULT state until it has passed a successful BIT

and will stop approximately 3 seconds after the fire is no longer detected.

Spectrex Inc. - SharpEyeTM ML & MU Flame Detector Manual – TM 767100, Rev. A, April 2005

4.2.1 Optional latching

The detector has an optional latched alarm output capability, which operates according to the programmable function. If selected, upon the detection of a fire, the detection signal is latched until manually reset (disconnecting the power supply or performing a manual BIT). Latching affects the ALARM RELAY, 4-20mA output, the ALARM LED.

4.2.2 Built-In-Test

When the programmable function “Alarm BIT” at YES, successful Manual BIT will activate the alarm relay for 3 sec. and the 4-20mA output will provide 20mA for 3 sec.

4.3 Detector Mode Setup

4.3.1 Detector setting

See Section 4.3.3 for default factory settings

The 20/20ML and 20/20MU incorporates several functions that can be set by the customer using Spectrex Host software, which will be supplied for each detector shipment

The Host software enables you to change functions as described in 4.3.2. Refer to manual TM 784050 for programming instructions.

4.3.2 Detector’s various functions

a. Sensitivity Ranges

The detector offers two (2) sensitivity settings. The settings refer to the

gasoline fire of 1ft

from

b. Alarm Delay

The detector is equipped with an Alarm Delay option, which provides programmable time delays of 0 to 30 seconds with eight (8) fixed settings: 0, anti-flare, 3, 5, 10, 15, 20, and 30 seconds.

The Alarm delay option will affect the alarm relay and the 4-20mA output When an Alarm (Detection) level condition is encountered, the detector

delays the execution of the Alarm output relay by the specified period of time. The detector will then evaluate the condition for 3 seconds. If the Alarm level is still present, the Alarm outputs will be activated. If this condition no longer exists, the detector will return to its standby state.. The LED will indicate warning level during the delay time only if the fire condition exists.

Spectrex Inc. - SharpEyeTM ML & MU Flame Detector Manual – TM 767100, Rev. A, April 2005

Anti Flare

Anti Flare mode is selected to prevent false alarm in locations where fast flares may be present. The Time delay for fire alarm in this mode is from 2.5 to 15 seconds (mostly less than 10 seconds).

Table 5: Time Delay

d. Addresses Setup

Refer to TM 784050 for instructions for defining the addresses of the detectors. The detector provides up to 247 addresses (from 1 to 247) that can be used with RS-485 communication link.

Spectrex Inc. - SharpEyeTM ML & MU Flame Detector Manual – TM 767100, Rev. A, April 2005

4.3.3 Detector Default Set Up

The detector has five (5) functions that can be programmed according to customer requirement at factory or at customer facility using software Host. The standard set up (default) that the detector is programmed to if there are no specific requirements are as follows:

Table 7: Default function set up

Detector default set up: 20/20ML 20/20MU Delay A 3 Alarm Latch NO NO Automatic BIT YES YES Alarm BIT NO NO

4.4 Built In Test

4.4.1 General

The detectors’ Built In Test (BIT) checks the following:

•

Electronics circuitry

• Sensors

• Window cleanliness

The detector can be set to perform the BIT automatically and manually or manually only.

4.4.2 Principles

If the result of a BIT is the same as the current status of the detector (NORMAL or BIT FAULT), the detector's status is unchanged. If the result of a BIT differs from the current status of the detector, the detectors’ status is changed (from NORMAL to BIT FAULT or from BIT FAULT to NORMAL).

Note: In BIT FAULT status, the detector can continue to detect a fire.

Spectrex Inc. - SharpEyeTM ML & MU Flame Detector Manual – TM 767100, Rev. A, April 2005

4.4.3 Automatic & Manual BIT

Manual Bit

Functions as described in section 4.4.4. In the case of an unsuccessful BIT all outputs will function as described in section 4.4.4.but the BIT will be automatically executed every 1 minute. This mode of operation will continue until successful BIT has been encountered. As a result, the detector will resume its normal operation.

Automatic BIT

The detector automatically performs a BIT every 15 minutes. A successful BIT does not activate any indicator.

• The FAULT relay remains CLOSED (NORMAL).

•

The LED continues to flash (1 Hz) at green.

• The 4-20mA output continues to indicate 4 mA.

An unsuccessful

BIT sequence activates the following:

• The FAULT relay is opened.

• 4-20mA output indicates BIT FAULT (2 mA).

•

The LED flashes (4 Hz) at yellow.

•

BIT procedure will be performed every 1 minute.

4.4.4 Manual BIT only

The BIT is initiated manually by momentarily connecting PIN No. 3 (or yellow wire) with PIN No. 2 (or black wire). A successful manual BIT activates the following:

• FAULT relay remains CLOSED.

•

ALARM relay is activated for 3 sec (only when Function Alarm BIT at YES)

• 4-20 mA OUTPUT current will be 20mA (only when Function Alarm BIT at YES).

• The LED will illuminate at red for 3 sec.

Unsuccessful BIT activates the following:

•

FAULT relay is opened.

• 4-20 mA output indicates BIT FAULT condition (2mA).

• The LED flashes (4 Hz) at yellow.

Note: During a MANUAL BIT, if Function Alarm BIT is in YES position, the

ALARM relay will be activated and the 4-20mA outputs will initiate 20mA. Therefore, automatic extinguishing systems or any external devices that should be activated under actual alarm conditions should be disconnected during BIT.

6. Installation Instructions

6.1 Scope

The SharpEye Models 20/20ML and 20/20MU are a self-contained Optical Flame Detectors designed to operate as a stand-alone units, directly connected to alarm systems or automatic fire extinguishing systems. The detectors can be part of a more complex system where many detectors and other devices are integrated through a common control unit. This Section does not attempt to cover all of the standard practices and codes of installation. Rather, it emphasizes specific points of consideration and provides some general rules for qualified personnel. Wherever applicable, special safety precautions are stressed.

6.2 General Considerations

Very Important

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 slight angle to prevent the accumulation of dust and dirt. Do not start an installation unless all conceivable considerations regarding detector location have been taken into account.

To ensure optimal performance and an efficient installation, the following guidelines should be considered:

A. Sensitivity

To determine the level of sensitivity, the following issues should be considered:

•

Size of fire at determined distance to be detected.

• Type of flammable materials.

B. Spacing and Location

The number of detectors and their locations in the protected area are

affected by:

• Size of the protected area

• Sensitivity of the detectors

•

Obstructed lines of sight

•

Cone of view of the detectors

• 20/20MU should not be used outdoors

C. Environment

•

Dust, snow or rain can reduce the detectors sensitivity and require more maintenance activities.

•

The presence of high intensity flickering of IR sources may affect sensitivity.

Spectrex Inc. - SharpEyeTM ML & MU Flame Detector Manual – TM 767100, Rev. A, April 2005

6.3 Preparation for Installation

Installation should comply with local codes or NFPA as applicable to flame detectors. The detectors can be installed with the use of general-purpose common tools and equipment.

1 Verify the appropriate Purchase Order. Record the Part No. and the Serial No.

of the detectors and the installation date in the appropriate Log-book.

2 Open the container package prior to detector installation and visually inspect

the detector.

3 Verify that all components required for the detector installation are readily

available before commencing the installation. In case that the installation is not completed in a single session, secure and seal detectors and conduits.

4 For wiring, use color-coded conductors or suitable wire markings or labels.

12 to 20 AWG (0.5 mm² to 3.5 mm²) wires may be used for site wiring. The selection of wire gauge should be based on the number of detectors used on the same line and the distance from the control unit, in compliance with specifications.

7. Operating Instructions

7.1 Scope

The following instructions are designed to obtain optimal performance from the detector over its life cycle.

7.2 Power-Up

1 Apply power and wait approximately 60 seconds for the automatic self-test of

the detector. Note: Applying power initiates the following sequence:

- the LED flashes (4 Hz) yellow.

- BIT is executed, if successful then:

- LED flashes (1 Hz) green,

- FAULT relay contacts close

2 Wiring Inspection: If a short-circuit or line discontinuity exists, indications will

appear on the control unit display panel. Review your wiring.

3 The detector goes into its FAULT state when supply voltage drops below

16.5V. The detector status goes back to NORMAL, when the supply voltage is above 17.5V.

4 Detector Inspection: Visually inspect the viewing window of the detector. It

should be clean and clear.

• LED should flash (1 Hz) green

• ALARM relays should be N.O

•

FAULT relay should be N.C

• The 4-20mA Output should be 4mA.

5 If any of the outputs or indications is different from the description in step 4,

see paragraph 8.6 for troubleshooting.

The Flame Detector is now ready for Functional Testing.

7.3 Reset (only when optional ‘latching’ alarm has been selected)

To RESET a detector when in its ALARM state, disconnect power, or initiate a manual BIT.

7.4 Functional testing

Following is a testing procedure for proper functioning of the detector. The detector can be tested using the Manual Built-in-Test or the Spectrex Fire Simulator - 20/20-311

Spectrex Inc. - SharpEyeTM ML & MU Flame Detector Manual – TM 767100, Rev. A, April 2005

7.4.1 Manual BIT Test

Momentarily connecting PIN number 11 or yellow wire with PIN 2 or black wire performs manual BIT.

Important Note!

If the function setup “Alarm BIT” is at YES, then the Alarm and 4-20mA Output will be activated during a manual BIT Therefore, automatic extinguishing systems or any external devices that may be activated during BIT must be disconnected.

1 Verify that the detector is operating properly. 2 Initiate manual BIT. After a few seconds the following occurs:

• Alarm Relay will be activated and the 4-20mA output turns to 20mA for 3 seconds (only if “Alarm BIT” at YES).

• The LED should light constant red for 3 seconds.

• Fault Relay should stay N.O during the test.

7.4.2 Testing with Fire Simulator Model 20/20-311 (see Appendix B)

This test simulates an exposure of the detector to a real fire condition. The detector is exposed to radiation at the required detection level. As a result the detector must generate a Fire Alarm signal.

Important Note!

If the detector is exposed to a fire simulator, the Alarm Relay and 4-20mA will be activated during the simulation. Therefore, automatic extinguishing systems or any external devices, which may be activated during this process, must be disconnected.

1 Apply power to the system and wait up to 60 seconds for detector to turn to

normal state and the LED flashes (1 Hz) green. If the detector is on, skip this step.

2 Aim the Spectrex Fire Simulator Model 20/20-311 at the target point of the

detector (see Fig. 15), in a way that the radiation emitted by it is facing directly towards the detector. (See appendix B)

3 Press the operation button once

•

The LED should light steady red for a few seconds.

. After few seconds,

• The 4-20mA output should turn to 20mA for a few seconds and then return to 4mA.

• The Alarm Relay should also turn on during this period.

This completes the installation procedure. The detector and system are now ready for operation.
