L717 Intelligent Power Supply Unit.
The L717 may be used with Intercall 700 & Intercall 600 systems provided all network devices were manufactured
after August 2003. 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. The L717 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. When using with an Intercall 700 with Intercom, the (A) and (B) cables do
not connect to this unit.
