PS 260/T 2-channel 4-Wire Interface
The PS 260/T 2-channel 4-Wire Interface enables connection of an ASL Pro Series intercom system to external audio equipment or to a 4-wire intercom system. Fixed 4-wire systems can be temporarily extended with ASL intercom stations, or a 4-wire TV camera intercom can be connected directly to an ASL network. Other applications include injection of external audio signal directly into the ASL intercom channels, or monitoring of the intercom signals by recording devices or paging systems.

PS 150 1-channel Telephone Interface
The PS 150 1-channel Telephone Interface connects an ASL Pro Series intercom with a telephone or 2-wire system. It enables communication between an ASL intercom network and a standard telephone, or between two ASL intercom networks via a telephone line.

PS 155 Wireless Interface
The PS 155 is a 1-channel audio interface for connecting simplex wireless intercom systems (PTT wireless intercom i.e. Motorola, Kenwood) to all ASL Analog Intercom systems. Special attention has been paid to ease of operation, enabling users to expand a wired ASL intercom with a locally approved wireless intercom subsystem.
Three modes are available to switch between send and receive, selectable on the front panel. The modes are:
PTT – Transmit mode enabled via an external switch connected to the PS 155.
VOX – Transmit mode enabled by an audio detection circuit on the wired intercom. The VOX circuit includes a special frequency contouring circuit for the human voice, with attack and release times adjustable on the PS 155 front panel.
CALL – Transmit mode enabled by pushing any CALL button on connected intercom units. All audio present at the wired intercom will be broadcast into the wireless system. Buzzers of all connected stations are automatically disabled in this mode.
