The detector is functioning normally. The detector performs a Built In Test.
PAGE 24
Spectrex Inc. - SharpEyeTM Mini IR3 Flame Detector Manual – TM 787100, Rev. D April 2011 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.
PAGE 25
Spectrex Inc. - SharpEyeTM Mini IR3 Flame Detector Manual – TM 787100, Rev. D April 2011 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. When an Alarm (Detection) level condition is encountered, the detector delays the execution of the Alarm output’s relay by the specified period of time. The detector will then evaluate the condition for 3 seconds.

Spectrex Inc. - SharpEyeTM Mini IR3 Flame Detector Manual – TM 787100, Rev. D April 2011 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. 4.4.3.
