L717 Budget Power Supply Unit is an Intercall Nurse call may be used with smaller Intercall 700 & Intercall 600 systems and the unit provides power and data signals for the network devices and stores the text programming information & when this is customised, it will need to be downloaded to any new display, call logger or pager interface installed on the system at a later date. The L717 is programmed using the LIMK Limkit programming kit and software which plugs into the connector on the right shown below. The system functions are configured using the DIP Switches on the L717.
IMPORTANT NOTE:
IMPORTANT NOTE:
The L617 600 Series Power Supply is still available for maintaining earlier Intercall 600 systems as you cannot replace the L617 with a L717 without ensuring all network devices are 600/700 compatible. Generally speaking, Intercall 600 devices manufactured after 2003/2004 are compatible with the L717.
