D.4.3 Phase 2: Use of lift under fire-fighters’ control
Operate the car control devices and confirm that the following conditions are all met.
a)
Where Phase 1 has been initiated by an external signal, the lift will
not operate until the fire-fighting lift switch has been operated.
[See BS EN 81-72:2005, 5.8.8a).]
Yes
b) Only one car call can be selected simultaneously.
[See BS EN 81-72:2005, 5.8.8b).]
Yes
c)
Yes
It is possible to register another call in the car whilst the lift is in
motion; this cancels the previous call and the car travels to the new
registered floor as quickly as possible.
[See BS EN 81-72:2005, 5.8.8c).]
d) Registration of the car call causes the lift to travel to the selected
floor and remain there with doors closed.
[See BS EN 81-72:2005, 5.8.8d).]
Yes
e)
When the car is stationary at a landing, pressure on the door open
button causes the doors to open, and release of pressure causes the
doors to re-close. When fully open, doors remain open until the next
call is selected. [See BS EN 81-72:2005, 5.8.8e).]
Yes
f)
Car door reversal devices and door open buttons remain operative
except those that could be affected by heat or smoke.
[See BS EN 81-72:2005, 5.8.8f).]
Yes
g) If the fire-fighting lift service switch is operated from “1” to “0”
for 5 s then returned to “1”, the lift returns to the fire access level.
[See BS EN 81-72:2005, 5.8.8g).]
Yes
h) Where an additional fire-fighting car key switch is fitted, it is
marked “1” and “0”, has a pictogram and the key is removable in
the “0” position only. If the fire service access level switch is set for
fire-fighting mode, the car key switch is set to “1” to allow car
movement. If the car key switch is set in the “0” position,
movement of the car is prevented and the doors remain open if
the lift is not at the fire service access level.
[See BS EN 81-72:2005, 5.8.8h).]
i)
Any registered car call is displayed visually on the car control panel.
