What type of devices are primarily located on engines in suburban fire apparatus?

Pre-connected devices are essential tools found on engines in suburban fire apparatus. They are configured to facilitate quick and efficient deployment of water supply lines during firefighting operations. These devices include hoses that are pre-loaded onto the apparatus and can be rapidly accessed by firefighters upon arrival at the scene. This design allows for immediate action in combating fires, minimizing time delays that can occur when stretching out hoses from a storage position.

Engine companies are typically responsible for fire suppression, which is why the presence of pre-connected devices is vital. Firefighters can quickly connect to a water source and engage with the incident without the need for extensive setup, maximizing their readiness and effectiveness.

While other devices such as safety devices may be included on the apparatus, they are not specific to the function of an engine in the same way that pre-connected devices are. Similarly, aerial devices are generally found on ladder trucks rather than engines and serve a different purpose in fire operations. Water-saving devices also do not directly align with the primary responsibilities of a suburban engine. Thus, the focus and necessity of pre-connected devices highlight their importance on engines in suburban fire apparatus.
