General Description

Description, Specifications, and Installation Manual

Keep all high-voltage and low-voltage wiring separated. If high-voltage and low-voltage 

wiring must be run together, all wiring must have an insulation rating greater than the 

maximum circuit voltage.
The relay output connectors accept 14-22 AWG wire. Four dry relay output contacts are 

provided with both normally open and normally closed contacts. 

Audio Input

The Audio Input is used to detect channel busy audio. The Audio Input detects from 

50 mV to 500 mV

p-p

.

Table 3 Audio Input

Terminal Description
1 and 2

Input from radio to indicate when radio is in use.

Radio and Audio PTT Outputs

The I-IPSIU has two SPDT relays rated at 5 A at 30 Vdc.
The relays are preset to activate when a voice message is initiated. These relays are used 

to active the push-to-talk (PTT) on the radio equipment.

Audio Out/Adjust

The audio output level is adjustable from 0 to 2.5 V

p-p

 into 600 ohms with 1 kHz tone. 

A removable eight-position connector is located on the rear of the I-IPSIU for making 

electrical connections. The connector accepts 5 mm (3/16 in) stripped wire, 18-26 AWG.
Make electrical connections to the Input/Output connector as follows.

Radio Connections

Use Tables 2, 3 and 4 to interface to the radio system or other external broadcast systems. 

Use Table 5 to interface between the I-IPSIU and radio. The Universal Adapter Cable 

provides flying leads on one end and a DB9 connector on the other. The DB9 connector 

interfaces to a second cable which provides the interface to the radio.
