As a result of the changing and more demanding environment for duty of care, there is the need to improve the facilities for the evacuation of disabled, injured or incapacitated persons from public premises. In an emergency evacuation situation or when the public power supply fails, an authorised person controls the ELPS from the externally installed switch by using a remote control key, like the ignition switch in a car. The “emergency power” switch is usually installed adjacent to the call button for the elevator or on the control panel in the lift car, and once activated powers the lift (elevator) hoisting system from its internal inverter and batteries independent of the mains power. The “on emergency power” button at the control point illuminates to signal power is being provided to the lift (elevator) traction system from the ELPS system.
