Fire detectors do not detect the presence of fire, rather they detect heat or smoke depending on the type of detector. Smoke detectors have a light inside which shines on a receiver when smoke is present in the room it rises up and causes a break in the light therefore activating the alarm, this also makes it common for false activations in these types of alarms due to dust and dirt in the air. Heat detectors on the other hand have a small plate on the outside which is temperature sensitive. Heat detectors can be reactant to different levels of heat depending on what their use it. Usually they are made to activate at around 185 degrees F. When the ambient temperature reaches this (very low temperature for a fire) the metal plate will melt off its contact points therefore activating the alarm. These are just two types of detectors.

What is fire detection in an alarm?
Fire detection is a crucial component of any fire alarm system, which is responsible for detecting and alerting people to the presence of a fire. A properly functioning fire alarm system with reliable fire detection capabilities is critical for ensuring the safety of occupants in buildings. There are various types of fire detection devices, including smoke detectors, heat detectors, flame detectors, and gas detectors. Smoke detectors are the most common type of fire detection device, which detects the presence of smoke particles in the air. Heat detectors, on the other hand, detect an increase in temperature that indicates the presence of a fire. Flame detectors detect the presence of flames, while gas detectors detect the presence of hazardous gases that could ignite and cause a fire. Fire alarm service in Glendora or any other location is also a critical aspect of maintaining a fire alarm system's proper function. Routine fire alarm service includes testing and inspecting the system's various components to ensure they are operating correctly. Fire alarm repair in California is necessary when any part of the system malfunctions or requires replacement. In conclusion, fire detection is a critical component of any fire alarm system, which is responsible for detecting and alerting people to the presence of a fire. Along with regular fire alarm service and fire alarm repair, reliable fire detection is essential for ensuring the safety of occupants in buildings. Therefore, it is crucial to maintain a functioning fire alarm system by investing in regular maintenance, service, and repair.
