 As noted in Lobby Control section, the driver of 1st due engine that assumes Lobby Control should identify the **churn/fire pump pressure** in the pump room noting if the fire pump is running or not. If Lobby Control cannot complete this, they should designate a member to perform this task. As noted in Lobby Control section, the driver of 1st due engine that assumes Lobby Control should identify the **churn/fire pump pressure** in the pump room noting if the fire pump is running or not.

 **Churn Pressure:** is the maximum pressure a fire pump can produce when it's operating at its rated speed but not discharging water. Fire pump pressure is the pressure of the pump while it is running and flowing water through standpipe or sprinkler head activation. When checking the fire pump to verify its pressure, the churn Pressure and Fire Pump Pressure may be slightly different. Keep it simple, pump at the observed pressure at fire pump controller gauge whether the pump is running or not. This should be reported as “Fire Pump Pressure” to Water Supply. **Churn Pressure:** is the maximum pressure a fire pump can produce when it's operating at its rated speed but not discharging water.

 Larger occupancies may have fire pumps that require greater operating pressure to reach remote standpipe connections. The standpipe connections closets to the fire pump often require PRD’s or PRV’s to lower the outlet pressure of the standpipe to a more manageable pressure. Larger occupancies may have fire pumps that require greater operating pressure to reach remote standpipe connections.

 **Fire Service** is specifically designed to provide a level of safety that cannot be achieved through other service modes, such as Automatic or Independent. It requires two distinct phases which firefighters must fully understand and implement to ensure safe and proper elevator use. It is important to note that elevators are subject to mechanical failure, and the safest means of ascent is using stairwells. There have been NIOSH Line-of-Duty Deaths (LODDs) associated with improper elevator use, such as the incident in Memphis in 1994. Therefore, elevators must always be in **Fire Service mode**, and it is crucial to avoid ascending to the floor of origin. **Fire Service** is specifically designed to provide a level of safety that cannot be achieved through other service modes, such as Automatic or Independent.

 Phase 1 Fire Service is activated when elevators bypass all floor calls and are immediately recalled to the lobby. Upon arrival at the lobby, the doors will open, and power will be automatically shut off. There are two ways to achieve this phase: automatically or manually. Phase 1 Fire Service is activated when elevators bypass all floor calls and are immediately recalled to the lobby.

-==Automatic Recall==+===Automatic Recall===
  
 The building’s fire alarm system may trigger automatic recall. When the alarm is activated, elevators are automatically recalled to the lobby. If the alarm detects smoke in the elevator lobby, some systems may implement a secondary plan, recalling the elevator to the next highest floor. Not all buildings are equipped with this feature, so crews should not assume that a fire is absent if the elevators are not recalled upon arrival. For example, in buildings like One Government Center, where certain elevators do not serve all floors, it is possible that not all elevators will be recalled. If elevators are not automatically recalled during a Commercial Fire Alarm (CFA), crews must initiate a **Manual Recall**. The building’s fire alarm system may trigger automatic recall.

 Manual Recall is initiated by firefighters by placing the fire service key into the switch IN THE ELEVATOR LOBBY and turning it to the “ON” position. At this point, all elevators in that bank will recall.                                   Manual Recall is initiated by firefighters by placing the fire service key into the switch IN THE ELEVATOR LOBBY and turning it to the “ON” position.

 To initiate Phase 2 Fire Service, the elevators **must first** be placed into Phase 1 Fire Service, either automatically or manually. It is recommended to turn the lobby switch to the “ON” position, even if the elevators have been automatically recalled. Additionally, it is critical to conduct a visual inspection of the elevator shaft using a flashlight, checking both above and below the car for any signs of fire, smoke, or water. This visual check should be repeated frequently during extended incidents. To initiate Phase 2 Fire Service, the elevators **must first** be placed into Phase 1 Fire Service, either automatically or manually.
