An emergency operations system is a collection of features and protocols built into an elevator to manage fire, power loss, or other emergencies. It ensures that elevators behave predictably and safely under stressful conditions.
In hydraulic elevators, this typically includes:
- Firefighters’ Emergency Operation (FEO)
- Battery Lowering Units (BLU)
- Emergency Alarm & Communication Systems
- Emergency Power Return Systems
🚒 Firefighters’ Emergency Operation (FEO)
Required by ASME A17.1 and the Florida Building Code, the Firefighters’ Emergency Operation allows firefighters to take control of the elevator during a fire.
Phase I – Recall Operation: When a fire alarm is activated, elevators automatically travel to a designated floor (usually the lobby) and park with doors open — preventing passengers from using them during a fire.
Phase II – Firefighter Control Mode: Firefighters can use a special key to manually operate the elevator and access specific floors as needed. This mode disables automatic functions and enables full manual control.
🔋 Battery Lowering Unit (BLU)
In the event of a power failure, a hydraulic elevator without counterweights may become stuck between floors. A Battery Lowering Unit activates to safely lower the cab to the nearest landing and open the doors, allowing passengers to exit safely.
This feature is especially critical in Florida, where hurricane-related outages are common. Florida code requires elevators in certain buildings to have a backup power source or equivalent emergency operation.
📞 Emergency Alarm & Communication Systems
Elevators must be equipped with:
- Alarm buttons for alerting building staff
- Two-way communication systems (e.g., speakerphones) connected to on-site security or a monitoring service
This ensures that trapped passengers can call for help at any time — even during power outages — which is a Florida code requirement for all new installations and modernizations.
⚡ Emergency Power Return Systems
In buildings equipped with emergency generators, hydraulic elevators can be configured to return to a designated floor and open the doors when primary power is lost.
This setup provides an added layer of safety and convenience, especially in facilities that serve vulnerable populations such as hospitals, senior living centers, or public buildings.
🏢 Florida-Specific Requirements
Florida Building Code and local jurisdictions often mandate enhanced emergency preparedness due to the state’s vulnerability to severe weather. Key requirements include:
- Backup systems (battery lowering or generator power) for elevators in buildings over a certain height
- Firefighter operations with standard Phase I and II features
- Maintenance of emergency signage and data tags
🚨 Why It Matters
Investing in a fully functional emergency operations system isn’t just about compliance — it’s about safety, liability prevention, and peace of mind for passengers, property managers, and first responders.
Regular inspections and testing by a licensed elevator company ensure that your system works when it’s needed most.
Conclusion
Hydraulic elevators are reliable, but emergencies can happen anytime. With a properly maintained emergency operations system in place — from battery lowering to firefighter controls — your elevator becomes a safer, smarter part of your building’s infrastructure.
If you’re unsure whether your elevator meets current emergency standards, contact a qualified technician for an evaluation. Being proactive could make all the difference in an emergency.
