What type of auxiliary fire alarm system connects through the municipal fire alarm system to the fire service communications center?

The correct choice is a local energy and shunt system. This type of auxiliary fire alarm system maintains a connection with the municipal fire alarm system and has the capacity to activate or communicate directly with the fire service communications center when an alarm is triggered.

A local energy system operates independently using its own power source, while the shunt function allows for routing signal transmission to the municipal system. This ensures that local alarms can effectively notify the fire department, even if the main system fails or is powered down.

In contrast, options like direct connection and networked alarm focus more on specific types of configurations. A direct connection typically implies a straightforward link without the additional functions provided by local energy and shunt systems. The networked alarm option suggests integration within a broader system, which may not imply the specific linkage to municipal firefighting resources that the question emphasizes. The remote signaling option indicates distance communication technology, which might not encompass the localized energy requirements described in the correct answer.
