4. QUEUE

The OPM-3SM incorporates a playback queue to manage the order that
messages play. This queue will manage up to 32 pages. Pages are put into the
queue on a first in, first out basis. The queue is compatible with pages from any
of the three page channels and/or the messaging input. The priority input offers
live, or direct, access to the output of the system. A priority page will pause the
playback queue. When the priority session completes, the queue will continue
from where it left off.

5. PRIORITY

The OPM-3SM offers a Priority input to gain immediate access to the public
address system. Activation of priority halts the playback of recorded pages.
When the priority page is completed, the OPM-3SM will resume playback from
the beginning of the message that was interrupted. Priority Activation methods
include Analog Station, Dry Loop and Loop Start. A valid connection via any of
these methods provides direct access to the system. Status of the Record
Activation switches is not relevant.

6. MESSAGING, PRE-RECORDED

The OPM-3SM offers a pre-recorded messaging system for quick and easy
access to standard or frequently used pages. This system allows messages to be
recorded and permanently stored in FLASH memory. Playback is provided via
DTMF command or contact closure. The messaging portion of the OPM-3SM can
store up to 99 messages in 8 minutes of memory.
