Alpha GD591 Handset for AA903/AA905 Master Station Features
The GD591 Handset is designed to be used in conjunction with the AA903 master intercom station, and RM5000EX or CB901EX intercom systems. The spiral cord for the K-style handset is a standard 4-wire type with modular connectors. A magnetic operated hook-switch design is used. The GD591 handset is designed for surface wall mounting and a backbox is not needed. When the handset is in the cradle, the master station is in handsfree mode, using the microphone and speaker on the master station. When the handset is lifted during a call, the speaker/ microphone on the master station is disconnected and the handset is used for confidential conversation. When the handset is placed back on the cradle, the call is automatically cancelled.
