What are alarm types, and how do they work?

Answer:
Portable gas detectors typically have two main types of alarms: visual and audible. Visual alarms include flashing lights or digital displays, while audible alarms produce sound signals. When the gas concentration exceeds a preset threshold, the alarms are triggered to alert the user.
