Contact Closure

The Niles MSU480 provides a contact closure that can be triggered one of two ways:

1.The presence of status voltage on the 3-30V AC/DC status input jack or

2.Discrete infrared on and off commands.

Set the contact closure dip switch, located above the screwless connector, to the appropriate position for triggering (Figure 8).

The discrete on and off commands are available for download at: www.nilesaudio.com/techsupport

Power Status — Introduction

The Niles MSU480 status port accepts 3-30V AC/DC input voltage and provides a visible status indication at the infrared sensor or IntelliPad.

When the MSU480 sees 3-30V AC/DC at the status jack it broadcasts a status signal over the IR sensor wires. Any appro- priate sensor or keypad connected to one of the sensor wires will display power status.
