Description
The Honeywell Flicker detector IRD1020.1 (SKU 16532) is an infra-red (IR) flicker detector, designed as a flame sensor for automatic flame presence monitoring. It is suited for gas and liquid fuel burners, with application in oil and industrial burners. The detection principle is the flicker of infrared radiation, requiring a line of sight to the flame. It is compatible with burner control (flame safeguard) systems and has an immediate response time. The device features an axial blue design.

| Operating Principle | Operates based on infrared radiation emitted by the flame |
| Output Signal | Signal indicating presence or absence of flame |
| Response characteristic | High sensitivity, quick and accurate detection |
| Safety Function | Immediately shuts off fuel supply upon flame loss |
| Safety feature | Prevents equipment failure and reduces risk of fire |
| Typical Failure Modes | Contaminated optical window; aged cell; damaged cable sheath |
Choosing and fitting
Replacement flicker detectors of this class are chosen by matching the detection principle, spectral range, and response time to the burner control requirements. Cable length, connector type, and mounting sleeve dimensions vary between manufacturers and must fit the existing burner assembly. During installation, ensure the sensor is correctly aligned with the flame and that its viewing window is clean, as an unobstructed line of sight is essential.
Signs of failure
Failure of this type of detector often appears as a contaminated optical window, an aged cell giving a weakened signal, or a damaged cable sheath. When the detector fails, the burner control may not receive a flame-present signal, leading to a safety lockout after the safety time expires. Checking the optical window for dirt and verifying cable continuity are typical steps in diagnosis.
