What specific type of alarm is activated in case of unauthorized access to a financial institution?

The type of alarm activated in the event of unauthorized access to a financial institution is an intruder alarm. This system is specifically designed to detect and alert personnel about unauthorized entry or suspicious activity within secure areas, such as banks or financial institutions. Intruder alarms typically utilize various sensors, including motion detectors, door and window sensors, and surveillance cameras, to monitor for signs of breach or intrusions.

While a security alert could encompass various types of security threats, it is not a specific term used to identify the alarm triggered by unauthorized access. A bank alarm is a more general term and may refer to a variety of security measures that are integrated within the institution, but it does not specifically reflect the main function of detecting intrusion. Fire alarms, on the other hand, are designed to detect smoke or heat from fires and are unrelated to the context of unauthorized access. Therefore, intruder alarms are the designated systems responsible for responding to potential threats of intrusion in a financial context.
