14. Configuring the I-IPSIU Radio Settings
The Informer Sensor Interface Unit (I-IPSIU) uses the audio out interface for broadcast
of alerts to radio systems. The audio output is a 600-ohm interface with manual volume
control. The I-IPSIU has relays which are used as the push-to-talk (PTT) to activate the
radio system. The PTT relays are dry contact closures which are closed when the audio
from the I-IPSIU is active. The I-IPSIU can use either a contact closure or audio input for
detection of a busy radio system. You can program the I-IPSIU to use the carrier detect
(contact or audio) to delay or prohibit announcements if the radio channel is busy.
To configure the radio settings:
1. From the Commander main window, click RTU. Select the unit to configure. Click
Configure.
2. Enter the name of the Informer, the address, and the latitude and longitude. This
information is used for mapping devices and for naming throughout the Commander
system.
NOTE: Use the table in Appendix B to record Informer’s information.
3. Click RTU Configuration.
