SmartSeries Remote Subset Amplifier

General Information

The Model 723-905 SmartSeries Remote Subset Amplifier is an intelligent handset amplifier, speaker
amplifier, and FSK modem intended for use in GAI-Tronics Page/Party
amplifier is an integral part of GAI-Tronics desktop, desk-edge, and flush-mount stations. It has been
designed to be remotely mounted with the enclosure, allowing the associated subsets to be mounted on a
desktop, on the edge of a desk, or flush mounted. The amplifier is not designed for outdoor use and must
be mounted at an indoor location.

For proper operation, the Model 723-905 SmartSeries Remote Subset Amplifier must be installed in the
Model 7245-005 Amplifier Enclosure with auxiliary inputs and used with one of the following subsets:

Single Party Subsets: Multi-Party Subsets:

®

and SmartSeries systems. The

Model 726-101 Desktop Subset Model 7265-101 Desktop Subset (5-party)

Model 711-102 Desk-Edge Subset Model 7115-102 Desk-Edge Subset (5-party)

Model 716-102 Flush-Mount Subset Model 7165-102 Flush-Mount Subset (5-party)

The SmartVolume™ feature is not supported for Model 7265-101. Also, the SmartVolume™ feature is
not available for speakers equipped with L-Pads or for multiple speaker applications. The Model 723­905 Remote Amplifier is designed solely for use with the magnetic hookswitch subsets listed above.
Subsets containing an RF hookswitch are not supported.

The Model 723-905 Remote Subset Amplifier provides the following features when installed in a
SmartSeries ADVANCE system:

• Enables one-way paging from the remote

subset handset. Priority Page feature
enables important messages to override
operational communication

• Enables two-way party line communication

from the remote subset handset

• Monitors and controls off-hook and page

status of the remote subset handset. Limits
off-hook and page durations to prevent open
microphone and nuisance page problems

• SmartVolume™ feature measures the ambient

noise and automatically adjusts the speaker output
level (desk-edge and flush-mount stations only)
when used with externally connected speaker

• Contains page amplification to broadcast

announcements over the station’s speaker

• Monitors and reports problems with handset

amplifier, the speaker amplifier, and speaker voice
coil to the MCU

• Supervises the externally connected speaker

(desk-edge and flush-mount stations only)

The following features are available as options to the standard configuration of a station used in a
SmartSeries ADVANCE system and installed in a special enclosure.

• The Selected Page Destination feature allows the manual selection of up to four page destinations.

• The Supervised Input feature allows the monitoring and supervision of one or two initiating device

circuits (IDCs), initiating an alarm when the supervised device is activated.

• The Power Relay Module provides a relay contact output, typically to switch power to a visual

signaling device, for directed or relay group operation. Supervision of the controlled device’s cable
can also be enabled.

• The Station Emergency Party Line feature supports annunciation for two party lines.
