When a fire handle is pulled, which system is NOT closed?

When a fire handle is pulled in the Embraer Regional Jet systems, the fuel shutoff and bleed shutoff systems are closed to prevent the fuel supply and bleed air from contributing to the fire. Additionally, the crossbleed shutoff is also activated to isolate bleed air from other systems. However, the electrical shutoff is not automatically closed when the fire handle is pulled.

Keeping the electrical circuits open allows for essential systems to continue functioning, which may include critical alerts and notifications needed for managing the situation and ensuring safety until the aircraft can be safely landed. This distinction highlights the protocol to maintain a level of control and awareness during an emergency, ensuring that flight crew members can take appropriate action without losing vital electrical power and systems communication.
