Final answer:
When installing exterior photoelectric beams, factors such as location, environmental factors, and interference need to be considered.
Step-by-step explanation:
When installing exterior photoelectric beams, there are several factors to consider:
Location: The position and angle of the beams need to be strategically placed to effectively cover the desired area.
Environmental Factors: Weather conditions, such as rain, wind, and extreme temperatures, can affect the performance of the beams. Consider choosing weather-resistant beams or using additional protective measures.
Interference: Other sources of light, such as street lamps or nearby buildings, can interfere with the beams, resulting in false alarms. It's important to assess and mitigate any potential sources of interference.
