3. Description of Operation:
In the event of an entrapment or other emergency, an elevator occupant may press
the “phone” button on the elevator control panel, causing the elevator phone to
automatically call for help. In TEL mode the Consolidator routes the call to either of
two phone lines connected or to the Consolidator then a phone line in sequence in
Intelli-Split mode or to the Consolidator in Lobby mode. The applicable elevator icon
will turn green.
If the call is not acknowledged within a reasonable time, the phone is required to
automatically hang up and dial a second phone number. If the phone line is busy,
the Consolidator will notify the parties on the original call that another call is waiting.
The Consolidator can call into any of the elevator phones. The caller selects which
cab by touching the appropriate icon which lights-up as soon as the consolidator
door is opened. If an icon is illuminated green the cab phone is busy on a call which
can be overridden by any of the in-building handsets.
Remote/Machine Room handsets can call into any cab, even overriding emergency
calls or joining another internal call in progress.
ALL CALL (system-wide paging) is available from all internal handsets as well as
from off-site.
Phone Line Monitoring (PLM) verifies the operation of the external phone lines as
well as the lines from each cab. Cabs are assigned to groups using the quick
program keys, with 3 group alarm relays available for every 6 cabs. Each relay
signals the appropriate EMC-ALRM board. Group “0” phones do not activate PLM
alarms.
Video trigger relays indicate whenever an emergency call from a cab is in progress.
