What device receives alarm signals from protected premises and re-transmits them to the Fire Department?

The device responsible for receiving alarm signals from protected premises and re-transmitting them to the Fire Department is known as a Central Station Transmitter. This device plays a crucial role in fire alarm systems, ensuring that any alarm activation within a building is promptly communicated to emergency services.

When an alarm is triggered, the Central Station Transmitter collects the data and sends a signal to the appropriate fire department, enabling a quick response to the incident. This function is vital in environments such as homeless shelters, where the safety of occupants is a top priority, and swift action can be vital in emergency situations.

While fire panels and alarm communicators have their specific roles within a fire alarm system—managing alarms and communicating with internal systems, respectively—they do not directly transmit alerts to external emergency services. Emergency relays may be used within the alarm system for local alarm sounds or notifications but are not responsible for transmitting alarm signals to the fire department. Thus, the Central Station Transmitter is the essential component for that external communication.
