Digital Acoustics HS-A1 Getting Started Manual

HS-A1

Getting Started Guide

Introduction

The HS-A1 is an analog handset with an armored cable and a hook switch
mechanism designed to be connected to an IP7 intercom module to enable full
duplex audio operations with a TalkMaster operator console or SIP Phone.

The HS-A1 can place a call by removing the handset from the switch hook. If
configured for TalkMaster, it will place an Incoming Call. If the IP7 is
configured to dial out to a SIP Extension, it will initiate a call to the specified
phone number.

If the HS-A1 is called from TalkMaster or from a SIP phone, the internal piezo
buzzer will sound to indicate there is an incoming call. The HS-1A must be
connected to either an IP7-SE8 or IP7-FD IP Module.

Installation

The Handsets are designed to be flush mounted in a 2-gang box. A 3-pair
cable is used to connect the Handset to an IP7-SE8. On the back of the
handset is a seven position 3.81mm DIN connector. The connection details
are:

For best audio quality, install the Handset as close as possible to the IP7
to reduce the chance of picking up audio noise. Use an 18 AWG 3-pair
multi-conductor with a shield. Refer to the IP7 Reference Manual for
instructions on connecting the shield and reducing audio noise.
