Electrical Requirements for Sensors and Relays
● HiPath1130/1150/1190
On the HiPath1130/1150/1190 the external audio source (e.g., music) is connected di-
rectly to the MB at the X8 slot (see Figure 3-3).
● Connection Values for an External Music Source*
*〉 This port supports commercial CD players, receivers, MD, etc. (See Figure 4-33, “Protection and Grounding
Connection Diagram”, on page 4-43).
The activation logic based on the initial position of the sensor contacts as well as its
resulting actions are programmable.
If a sensor is programmed, the relay can be activated through that sensor. It can be
activated either manually or automatically after a specified time. When the relay is
activated, the contacts close. When it is deactivated, the contacts open.
