Organisation in spines is useful because if a spine
fails (spine bus short-circuit or faulty door phone),
it can be cut off from the system permitting the
remaining spines to work normally.
STAIRCASE LIGHT CONTROLLER RELAY
The coupler is equipped with a low voltage contact
controlled for one second subsequent to the
following events:
• pressing of "staircase lights" button on any door
phone connected to the respective spines;
• pressing of "staircase lights" button on secondary
door unit connected to the respective spines;
• pressing of "staircase lights" button on any main
door unit (with digitiser only);
• pressing on concierge switchboard button F1.
TROUBLESHOOTING
The bus coupler has two LEDs indicating the status
of the respective door phone spine. One or more
coupler LEDs will go out to indicate a short-circuit
on the corresponding door phone spine.
