State conditions under which the following detectors is likely to give a false alarm.1) optical detector and heat detector ?

1) Optical detector:
- Dust or other particles in the air can trigger a false alarm by scattering light and causing the detector to mistake it for smoke.
- Steam or humidity in the air can also trigger a false alarm by refracting light and causing the detector to mistake it for smoke.
- Insects or small animals moving in front of the detector can also trigger a false alarm by blocking or reflecting light in a way that the detector interprets as smoke.

2) Heat detector:
- High humidity or condensation can cause the detector to falsely detect a rise in temperature and trigger an alarm.
- Nearby heat sources such as ovens, heaters, or direct sunlight can cause the detector to falsely detect a rise in temperature and trigger an alarm.
- Dust or debris buildup on the detector can insulate it and cause it to falsely detect a rise in temperature.

Optical detectors:

- Dust and dirt accumulation on the optical sensor
- Steam or smoke from cooking or other sources
- Fumes from solvents, cleaning agents, or adhesives
- Insects or debris entering the detector
- High humidity or condensation
- Misalignment of the detector

Heat detectors:

- High ambient temperature caused by heating appliances, sunlight, or proximity to hot surfaces
- Excessive heat from nearby light fixtures or other sources
- Rapid temperature changes, such as after a door or window is opened
- Steam or moisture from showers, baths, or other sources
- Heat buildup from overloaded electrical circuits or malfunctioning equipment
- Installation in a location where the detector is not exposed to free air circulation
