PHAST LCD keypads must connect
directly to a PHAST Hub (or PHAST
Microphone Hub). Due to power
requirements and/or the need for a
separate microphone line for each
keypad, they cannot be daisy
chained to other LCD keypads; they
can, however be daisy chained with
other PHASTLink devices.
When connecting PHAST keypads
that will be used as intercoms, the
Microphone Hub taps off the
intercom audio signal carried on the
PHASTLink cable from that keypad.
PHASTLink devices cannot be wired in a star configuration.
Troubleshooting
The green LED on the SAM is not illuminated.
This condition indicates that the SAM is not powered up. Check the following:
•
Make sure the Landmark system is running.
•
Follow the PHASTLink cable back to the PHASTLink hub or cardframe, and check the RJ-45 connections, as
described in "PHASTLink Cable Information."
•
Check the Network Assignments tab in the Landmark Designer software and make sure the Vantage Q System
has been properly identified and logically connected.
