They receive a signal from a fire sensor (smoke, heat or carbon monoxide detector) and automatically transmit it to the fire alarm panel. In wireless systems, the signal from the detectors to the control panel is transmitted with radio frequency. Heat detectors usually have built-in thermistors to sense the heat.

Fire Protection: The Four Types of Fire Detectors The four types of fire detectors are ionization/photoelectric, photoelectric, ionization, and heat. The differences in these four types are found in how they detect a fire – heat is obviously triggered by temperature while the other three are from smoke.

With fire alarm monitoring, the system is connected to the fire department. When smoke sets off a fire alarm, heat triggers a sprinkler head, or someone activates a manual pull station, a message is sent to the central monitoring station where an operator immediately notifies the appropriate local fire department.

In commercial and residential intrusion and fire alarm systems circuits are typically DC. However, most residential doorbells are 24vac. An ac transformer is simpler and cheaper to make. As you can see the light and the doorbell switch are in parallel with each other.
