Program Channel Step and Volume Step may be done with a single input as
long as the input provides a 100ms DC Shift when the substation is idle and
provides a 200ms DC Shift when the substation is busy (the station is turned
on). The operation will be as follows:
Once SVT has been programmed, if the input is activated while the station
is idle, then a “1" will be dialed for the substation. Direct Dialing will force a
“949" which will step to the next Program Distribution Channel at a Volume
of 1 (turning on the substation). If the input is activated at this point, the
station is considered busy, and a “2" will be dialed for the substation. Direct
Dialing will force a “948" step to the next Volume level of the present
Program Distribution Channel. The volume will continuously be stepped by
activating the input until the Volume wraps around turning the Program
Distribution Channel off. At that point the next activation of the input will turn
on the next available Program Distribution Channel at Volume 1. Each
successive activation of the input will continue this loop until the Program
Distribution Channel wraps itself around back to the first available Program
Distribution Channel and start all over again.
5 = Direct Dial subscriber port. When DC shift is detected this port will dial the
call number programmed i n R
ECORDER DIAL NUMBER. When DC shift is
removed the connection is cancelled.
6 = Method C elevator substation. When permanent DC shift is detected an
alarm is sent to the annunciator panel.
The alarm is cleared when the station
is called back from the annunciator or from a master-station dialing the
station (the elevator station must remove DC shift when called).
7= Supervised sub-station with two buttons (Call and Alarm). The Alarm button
will send ALARM to annunciators starting at annunciator address 1 and can
transfer to address 2-8 with optional delay. The Call button will send CALL
to annunciator address 8 and can transfer to address 7-1 with optional delay.
FAULT will follow the ALARM transfer.
