machine room along the
suspension cable to the emergency
telephone mounted on the car top,
to which it is connected.
BNOS lift emergency

The lift emergency telephone 20-0028 is available either as a single unit or in two sets:
20-0021
Set 1 = telephone 20-0028 plus external loudspeaker and microphone with all connecting cables.

Connection
3
Step 1:
– Connect loudspeaker, microphone and buttons for inside the car = MLM A.
– Connect outside-car speech module for on top of the car, if required = MLM B (not in the case of 20-0028).
– Connect outside-car speech module for underneath the car, if required = MLM C.
Step 2:
Connect 12 V DC, if required (must be potential-free – use BNOS UPS or existing emergency power supply in
conjunction with BNOS DC/DC converter).
Only required for: illumination, camera, integrated heating, integrated add-on amplifier, connecting 12 V
through to an MLM.
Not required for: telephone operation, including all functions.
Step 3:
Connect telephone line (a/b line from analogue PBX extension or analogue direct exchange line) => a long
beep signals the telephone's operational readiness.
