ISSUE 15
If a car is already on fire phase 2 when ESUP is activated then this is automatically the duty car and will stay that
way.
When all cars are returned to their relevant floors or have been found to have stalled 3 times the fire duty car will
become Duty Car if it has not stalled.
Inputs: "ESUP ", "Emergency Supply"
Emergency Recall
Emergency recall takes the lift out of normal service and parks the lift at its recall floor. Three emergency recall
inputs provide recall to specified recall floors.
Inputs: "EMR1 ", "Emergency Recall 1" + "EMR2 ", "Emergency Recall 2" + "EMR3 ", "Emergency Recall 3"
Engineers Access
When activated Engineers Access Control will take the lift to a point in the shaft at levelling speed and then stop to
allow the lift engineer to easily gain access to the car top.
Inputs: "EAC ", "Engineer's Access Ctrl Ip" + "EAS ", "Eng's Access Stop Input"
Fire Recall
The lift will operate as EN81-73 describes: - Once initiated the lift will travel to the fire floor as soon as possible. If
the doors are open they will nudge closed, if available. Note: the door open push and the safety edge will be
ignored. If the lift is travelling in the wrong direction, it will stop at the next available floor and without opening its
doors return to the fire floor. When at the fire floor the doors will open and remain open. (They may be set to dwell
closed in customer settings). No car or landing calls can be entered. Throughout this service the FRI (Fire Recall
Indicator) output will be active.
Inputs: "FAM ", "Fire Alarm Recall"
Fire Service (Firefighting)
The lift will operate as EN81-72 describes: - Operation of a single pole Fire Control Switch installed on the main
landing will immediately initiate Phase 1 Fire Control Return.
Phase 1 Fire Control, the lift will return to the fire floor as quickly as possible. The following sequence of operations
will occur: -
All calls will be cancelled. If the lift is travelling away from the fire floor, the car will slow and stop at the next
available landing, the doors will remain closed and following a short delay the lift will start to return to the fire floor.
If the lift is travelling towards the fire floor, the lift will continue to the fire floor without interruption.
If the lift is at a landing with its doors open, the doors will nudge close immediately if available and the lift will
proceed to the fire floor, the door open push will remain operative in this phase.
Throughout the Fire Service Control sequence the "Fire Control" FCI indicator will be illuminated, landing calls will
remain inoperative and the Safety Edge (or the heat sensitive door devices) will be disabled.
Once at the fire floor the firefighting lift will park with its doors open and Phase 2 Fire Service operation will begin.
Phase 2 Fire Service, the following operations will exist on the firefighting lift:
Once they are fully closed, the doors will only open via constant pressure on the door open push. If the push is
released before the doors have fully opened they will automatically close. Once the doors are fully open they will
remain open until constant pressure of a call push causes them to close. If the call push is released before doors
are fully closed, the doors will re-open, all calls be cancelled and the lift will park with its doors open until a car push
is re-operated. The safety edge will be disabled.
Once the lift is moving, only one call will be accepted at any point, a new call entered will cause the original call to
be cancelled, the lift will travel to the last call entered. If moving away from the floor the lift will stop and reverse
direction. Once at the selected floor the doors will remain closed until signalled to open by constant pressure
operation of the door open push.
The lift will only return to normal operation if the fire control switch is in its 'Off' position, the lift is at the fire floor and
the doors are fully open.
Switching the fire control switch 'Off' for a minimum of five seconds and then to 'On' again, at any time, will always
cause the lift to return to the fire floor. Unless fitted with an in car fire switch, this switch must be on for the lift to
move whilst in phase 2.
Inputs: "FSR ", "Fire Service" + "FCS ", "Fire Car Switch"
Hospital Service
On entering a Hospital call the dispatching function will determine which lift will go on to Hospital service, all other
lifts in the group will stay on normal service. Only lifts capable of performing the service will be available. If a lift has
a fault, is on a higher priority service or is overloaded, then it is unavailable. A Hospital call cannot be placed at a
blank floor.
