A device which can detect a fire, and provide a signal to an alarm circuit. Fire detectors can be operated by smoke, flames, and heat, or any combination of these factors. Flame detectors are rarely used on board ships these days. Heat detectors are used in places such as the galley and laundry. Smoke detectors are used in machinery spaces, accommodation areas and cargo holds.
Heat Detector Heat detectors are generally used in storage closets, warehouses or other rooms that aren't frequently occupied. They will alert you when there's a rise in the room temperature or if there's a significant amount of heat in the room. The issue with heat detectors is they take a little longer to detect a fire than smoke detectors. However, they have fewer false alarms because they don't go off when there's steam, dust, humidity or precipitation.
Ionization Smoke Detector Ionization smoke detectors are usually found in commercial kitchens and restaurants. They activate when there's smoke present in the air. The detector has two metal plates inside, which have a constant electric current that flows back and forth. Once smoke enters the chamber, the current will no longer flow and the alarm will sound. Photoelectric Smoke Detector
Photoelectric detectors are great for detecting small fires. They are similar to ionization detectors, but instead of using an electric current, they use a beam of light to detect smoke. When smoke enters the chamber on the photoelectric detector, then it will interfere with the light and the alarm will go off.
Ionization and Photoelectric Smoke Detector A smoke detector that senses both ionization and photoelectric smoke is the best way to arm your building. This detector combines both the ionization and photoelectric detectors to work as one unit. When there's smoke in the air, it will disrupt both the beam of light and electric current, which will cause the alarm to sound. The best thing about this detector is it works as a 2-in-1 system, however it won't be able to detect heat
