A lift intercom is a communication system installed in a lift that allows passengers to communicate with someone outside of the elevator car in case of an emergency or other situation where assistance is needed. Lift intercoms typically consist of a speaker, microphone, and call button located inside the elevator car. In the event of an emergency or if a passenger requires assistance, they can press the call button to speak with someone outside. 12V / 24V DC Supply, 1 Car Unit, 2 Handsets , 1 Control Unit 230V AC/24V DC, 1 Car Unit, 2 Handsets, 1 Control Unit, Battery backup 12V / 24V DC Supply, 1 Car Unit, 2/3 Handsets, 1 Control Unit, lift and talk model Applications Emergency communication Security monitoring Maintenance and repair Elevator Intercom Specification
