Installation
2 Installation
2.1 Installation guidelines
Installation should comply with the National Fire Protection Association (NFPA) 72E or any
other local and international regulations and standards, as applicable to flame detectors
and installation of Ex approved products. To ensure optimal performance and efficient
installation, consider the following guidelines.
Sensitivity
To determine the level of sensitivity, consider the following:
• Size of fire at the required distance to be detected
• Type of flammable materials
• Proximity to false alarm sources
Wiring
The wire gauge must be designed according to the distance from the detector to the
controller and the number of detectors on the same power line.
To fully comply with EMC directive and protect against interference caused by RFI and EMI,
the cable to the detector must be shielded and the detector must be grounded. The shield
should be grounded at the detector end.
Spacing and location
The number of detectors and their locations in the protected area are determined by:
• Size of the protected area
• Sensitivity of the detectors
• Obstructed lines of sight
• Cone of view of the detectors
Environment
Dust, snow, or rain can reduce the detector’s sensitivity and require more maintenance
activities.
The presence of high intensity emission sources may affect sensitivity.
2.2 Preparation for use
The installation sequence may vary according to the physical structure of the site.
Note
Installation steps are also detailed in the Quick Start Guide supplied with the detector.
The following tools are required for installation. These are standard tools and are not
supplied with the detector.

Operation
3 Operation
3.1 Power up the detector
Procedure
After connecting the detector to power, wait up to 60 seconds for the detector to
completed the initial start-up procedure.
Note
Turning on the detector initiates the following sequence of events:
a. The yellow light-emitting diode (LED) flashes at 4 Hz.
b. The built-in test (BIT) is executed.
c. BIT completes.
d. Detector enters Normal mode, indicated by:
• Flashing green LED at 1 Hz.
• Fault relay contacts closing.
• mA output is 4 mA (for models featuring analog [voltage] output, this will be 2
V).
3.2 Testing procedures
This section describes the explosion proof testing procedure using the Spectrex™ explosion
proof FS flame simulator series. The detector can also be tested using the Manual BIT.

To perform a flame simulator test:
1. Power up the system and wait for up to 60 seconds for the detector to return to
normal status.

Initial setup
4 Initial setup
4.1 Continuous feature test
The detector is supplied with default settings, including a continuous feature test.
To change these settings, refer to the Spectrex SharpEye 40/40C and D Series Flame
Detectors Modbus® Manager Manual.
During normal operation, the detector tests itself continuously and indicates a fault if a
failure is found. This type of test complies with SIL-3 requirements.
The detector continuously tests:
• Input voltage level
• All internal regulator voltage level
• Voltage level status of sensor and sensor circuitry for noise or disconnection in the
electronic circuitry
• 0-20 mA level output
• Relays and heater operation
• Processor watch dog
• Software
• Memory
• Oscillator frequency
4.2 Response to fault indication
If a failure is found, the detector indicates by:
• Light-emitting diode (LED): yellow flashes (4 Hz)
• Fault relay opens
• 0-20 mA: 1 mA default
• Analog voltage output: 0 V output
(SharpEye 40/40D models only)
The fault indications remain until the detector is turned off. The fault indications return if
the fault is still found when power is restored.
4.3 Built-in-test (BIT)
The detector's BIT checks the following:
• Sensors
• Window cleanliness
SharpEye 40/40 27
Page 28
Initial setup Reference Manual
December 2021 00909-0100-4975
• Electronic circuitry
The detector can be set to perform the BIT in the following modes:
• Automatically and manually
• Manually only
BIT operation
The BIT is intended to check optical integrity and electronic circuitry. The detector's status
remains unchanged if the result of a BIT is the same as the current status (Normal or BIT
Fault). The detector’s status changes if the BIT differs from the current status.
Note
In BIT Fault status, the detector can continue to detect a fire in most cases.
Automatic BIT
The detector automatically performs a BIT every 15 minutes. A successful BIT sequence
does not activate any indicator. The BIT interval can be modified if required by the
customer using the RS-485 Modbus® Manager or HART® communicator. In case of a BIT
fault, this sequence continues until a successful BIT occurs, when the detector resumes
normal operation.
• As result of successful automatic/manual BIT, the fault relay remains energized.
• As result of unsuccessful automatic/manual BIT, the fault relay de-energizes.
Manual BIT
You can initiate manual BIT using the Modbus® Manager or HART® communicator.
Connecting terminal 3 to ground also initiates manual BIT. Alarm duration during manual
BIT is configurable using the Modbus Manager or HART communicator.

6 Troubleshooting
6.1 Light-emitting diode (LED) is off, fault relay is open, 0-20 mA shows 0 mA, analog voltage output is 0 V
Note
Analog voltage output applies to SharpEye 40/40D models only.
Potential cause
No power to the unit.
Recommended actions
1. Check that the operating voltage is correct, according to Electrical
specifications.
2. Check power polarity.
3. Check the terminal wiring.
6.2 Light-emitting diode (LED) flashes yellow at 4 Hz, fault relay is open, 0-20 mA shows 1 mA
Potential cause
Low voltage.
Recommended action
Check that the operating voltage is correct, according to Electrical specifications
Potential cause
Faulty detector.
Recommended action
Re-power the detector.
6.3 Light-emitting diode (LED) flashes yellow at 4 Hz, relay is open, 0-20 mA shows 2 mA
Potential cause
Built-in test (BIT) fault.

Troubleshooting Reference Manual
December 2021 00909-0100-4975
Recommended action
Ensure the detector window and reflector mirror are clean.
Potential cause
Faulty detector.
Recommended action
Re-power the detector.
6.4 Light-emitting diode (LED) constantly red, alarm relay energized, 0-20 mA indicates alarm
Potential cause
Existing alarm condition.
Recommended action
Check cause of alarm.
Potential cause
Alarm latched.
Recommended action
Ensure the alarm latch is not enabled in the detector settings.
Potential cause
Faulty detector.
Recommended action
Re-power the detector.
6.5 No HART® communication, 0-20 mA shows 0 mA
Potential
No HART is available at 0 mA level.
Recommended action
For Fault mode, the default indication is 1 mA. Configure this to 0 mA.
Emerson does not recommend this when using a HART connection in order to
preserve the HART communication.
