What scenario is represented by the dispatch code x90T?

The dispatch code x90T typically indicates a test of the alarm system. This code is used to signify that the alarm is being tested to ensure it is functioning correctly without indicating any actual emergency or service requirement. It’s crucial for maintenance checks and ensures the equipment is operational, thereby preventing potential issues during real incidents.

In contrast, the other scenarios would involve different codes that relate to actual repairs, weather-related incidents, or malicious activities, which would require a different response protocol and would not simply be a testing situation. Therefore, understanding the implications of dispatch codes is essential for effective incident management and response.
