How many master alarm panels can a single initiating device actuate?

The capability of a single initiating device to actuate multiple master alarm panels is a crucial aspect in the design and functionality of alarm systems in medical gas installations. This design allows for enhanced flexibility and coverage across different areas of a facility.

When an initiating device, such as a flow switch or a pressure switch, is activated, it can trigger multiple master alarm panels simultaneously. This means that alarms can be displayed in various locations throughout a facility, allowing for prompt awareness and response by personnel regardless of where they are situated. This multichannel capability ensures that critical information about the status of medical gases is communicated effectively, enhancing safety and operational efficiency.

In contrast, the other options either limit the functionality to a single master panel or refer to devices that serve different roles in the alarm system, such as area alarm panels or computers, which do not play a direct part in the actuation process initiated by a single device. Thus, the ability for one initiating device to actuate multiple master alarm panels is fundamental in providing a comprehensive and responsive alarm system within medical gas installations.
