Fireman's Lift and Emergency Power for Life Safety
An engineer-written guide to firefighter lifts and emergency power — how a fire lift is protected and operated, and how standby supplies keep lifts, pumps, alarms and smoke control running during a fire.
During a fire, normal lifts are taken out of service because they can carry occupants into danger or fail with the power. A firefighter lift is different: it is engineered to keep working under fire conditions so firefighters can move crews and equipment up tall buildings quickly instead of climbing stairs under load.
For that lift — and for pumps, alarms, smoke control, and emergency lighting — to keep operating, the building needs a reliable emergency power arrangement. This lesson explains how a firefighter lift is protected and controlled, and how standby supplies and automatic transfer keep the essential life-safety loads energised when the mains fails.
How it works
Why firefighter lifts exist. In a tall building, sending crews and heavy equipment up many flights of stairs is slow and exhausting and delays the attack on the fire. A firefighter lift gives them a protected, powered route upward. It is for firefighter use under their control during the incident — not for occupant evacuation, which uses the protected stairs.
Protection and the fireman’s switch. The fire lift sits in a protected shaft and is served by protected lobbies, so fire and smoke are kept away from the car and landing doors. A firefighter’s control switch (often at the entrance level) puts the lift under manual firefighter control, with priority over normal calls, so the crew decides where it goes.
Fire recall. On a fire signal, lifts are recalled: cars return to a designated level (usually the ground or a defined fire-recall floor) and park with doors open so no one is trapped between floors. Normal lifts then stay out of service, while the firefighter lift becomes available to firefighters under the control switch.
Emergency and standby power. Life-safety systems must keep running when the normal supply fails in a fire. A standby source — typically a generator, sometimes supported by batteries/UPS for instantaneous loads — feeds an essential (life-safety) section of the distribution. This is what powers the firefighter lift, fire pumps, alarm and detection, smoke control, and emergency lighting.
Automatic transfer and protected wiring. An automatic transfer switch (ATS) detects loss of the mains and starts the generator, transferring the essential loads to it within seconds, then transfers back when normal power returns. The supplies and circuits feeding life-safety equipment use fire-rated cable on protected routes and are supervised, so the essential loads survive and operate for the required duration during the fire.
Main types
In the UAE
- Firefighter lifts and emergency/standby power for life safety follow the UAE Fire & Life Safety Code of Practice and are reviewed and inspected by Civil Defence (in Abu Dhabi, ADCD), with the electrical supply coordinated with ADDC.
- Essential life-safety loads — fire lift, pumps, alarm, smoke control, and emergency lighting — must be fed from a standby supply with automatic transfer and fire-rated cabling on protected routes.
- Fire recall, the firefighter control switch, protected shaft/lobby, and standby-power operation are verified together at Civil Defence commissioning before occupancy.
How GPR applies this
As an Abu Dhabi MEP and fire contractor, GPR delivers the electrical side of firefighter-lift and life-safety power — an essential distribution fed by a standby generator through an ATS, with UPS where instantaneous backup is needed, all on fire-rated cable and protected routes. GPR coordinates fire recall and the firefighter control switch with the lift supplier and fire alarm, and commissions the whole arrangement for ADCD inspection and handover.
Frequently asked questions
What is a firefighter lift?
A lift engineered to keep operating under fire conditions in a protected shaft, placed under manual firefighter control during an incident so crews and equipment can be moved up a tall building quickly. It is not for occupant evacuation.
What is fire recall of lifts?
On a fire signal, lift cars automatically return to a designated level and park with doors open so no one is trapped, after which normal lifts stay out of service and the firefighter lift is used by firefighters.
Why do life-safety systems need standby power?
Because they must keep working when the normal supply fails in a fire. A standby generator (sometimes with UPS) feeds an essential section that powers the fire lift, pumps, alarm, smoke control, and emergency lighting.
What does an automatic transfer switch (ATS) do?
It detects loss of the mains, starts the standby generator, and transfers the essential loads to it within seconds, then transfers back when normal power returns.
Why is fire-rated cable used for these supplies?
So the essential life-safety circuits keep operating during the fire for the required time; fire-rated cable on protected routes resists fire damage and the circuits are supervised for integrity.
