WIRING DIAGRAM
This diagram shows a single entrance vandal resistant door panel connected to multiple
apartments with full isolation to prevent a single apartment compromising the whole
system.
The lock release shown is fail secure. The SP35 door monitoring PCB is also shown along
with a set of normally closed door contacts. This will be used to activate the door open
LED on the telephone handsets.
The isolation cards each support four apartments. All the isolation cards can be mounted
together in one location or separately on each landing.
