What are the two types of fire alarm boxes?

The two types of fire alarm boxes are categorized as single action and double action. Single action fire alarm boxes require only one step to activate the alarm, typically involving simply pulling a handle or lever. This design allows for quick activation, which can be critical in emergencies when every second counts.

In contrast, double action fire alarm boxes necessitate two distinct actions to trigger the alarm. This usually involves pressing a button or pulling a handle followed by another action, such as additional pushing or pulling. The double action requirement reduces the likelihood of accidental activations and ensures that individuals intentionally activate the alarm in a genuine emergency.

This differentiation is crucial for understanding how fire alarm systems function and their respective roles in safety protocols. By knowing these two types, one can better understand the responses required during emergency situations and the rationale behind the design of fire alarms.
