Which type of notification is NOT included in the four types of notifications for alarm systems?

In the context of alarm systems, the four primary types of notifications typically include audible, visual, and tactile forms, which are designed to alert users of an alarm event through sound, sight, and physical sensation, respectively. Textual notifications, while they can be part of modern communication systems that send messages or alerts, are not classified as a standard form of notification for alarm systems.

Audible notifications utilize sounds or alarms to capture immediate attention, while visual notifications involve lights or displays that convey information visually. Olfactory notifications are rare but are theoretically related to detecting specific odors as alerts—though they are not standard in typical alarm systems. Textual notifications may exist in the form of messages sent to a mobile device, but they do not represent a direct alerting method of the alarm system itself.

Recognizing the types of notifications that are standard and established is vital in understanding the different forms of communication that alarm systems may utilize in alerting users to potential issues or breaches. Thus, textual alerts are not typically included in the core types of alarm notifications.
