- Different types of detectors are installed within a fire alarm system. A detector evaluates the condition when there is an emergency or when they trigger the fire. But the detectors require cleaning on regular basis otherwise they will not perform their function properly.
- Call points are also present within the fire alarm system. Call points are used to initiate the audio signals manually. They just have a button and we just need to push the button. Call points can also work automatically.
