4 SAFETY DEVICES
The Alpha stairlift is equipped with the following safety features:
4.1 Armrests
The armrests, which must be closed (horizontal) or folded up while driving empty, prevent falling
from the chair and act as support for getting in and out of the chair in the landings.
4.2 Contact bottom
The contact bottom is attached to the underside of the footrest and serves as an additional safety
feature. It reacts to pressure so that the system stops immediately if the footrest hits an obstacle.
The travel command in upward direction remains active.
4.3 Lateral covers on the drive and carriages
Contact-sensitive covers are fitted to the sides of the drive and the carriages, which prevent
jamming in the direction of travel. The travel command in the opposite direction remains active.
4.4 Emergency stop (optional)
The stairlift can be equipped with an emergency stop button. If you need to stop the stairlift in an
emergency, press the red button and the lift will stop. Unlocking is done by pressing it again or
turning it clockwise.
4.5 On/Off switch
The stairlift is fitted with an on/off switch. When the lift is not in use, this switch should be turned off.
4.6 Alarm button (optional)
The stairlift can be equipped with an alarm button to summon help. Pressing the alarm button will
sound a loud emergency signal.
4.7 Speed limiter and safety gear
The stairlift is equipped with a speed limiter and a safety gear. If the stairlift descends at an
increased speed (e.g. due to a defect or similar), the increased speed is immediately detected by
the overspeed governor and the safety gear is triggered. The safety gear brings the stairlift to a
stop by holding it against the rails. This prevents the stairlift from falling.
