USING THE CONTROL OUT
The CONTROL OUT connector has 4 screw terminals and provides two different outputs. The two terminals on the left provide a set of normally open, dry relay contacts, and the two terminals on the right provide a 12Volt DC output.
The set of dry contacts close whenever the SAS-1 is triggered. They will remain closed as long as the signal that triggered the SAS-1 is present. Depending on the setting of the delay control, they will open anywhere between ¼ of a second to 30 seconds after the signal that triggered the SAS-1 is removed. With this feature, the SAS-1 can activate television lift systems, operate electric projector screens, control lighting systems, etc.
The 12Volt DC is present at the other two terminals whenever the switching section of the SAS-1 is activated. Depending on the setting of the delay control, the voltage turns off anywhere between ¼ of a second to 30 seconds after the signal that triggered the SAS-1 is removed. This feature is provided as a convenient interface for using the SAS-1 to control other Niles switching devices, such as the AVS-2, SPK-1 and RFS-1. Refer to the section titled “System Expansion” for more details.
NOTES: THE DRY RELAY CONTACTS CAN SWITCH A MAXIMUM OF 28VOLTS DC AT 1 AMP. THE 12VOLT DC OUTPUT CAN SUPPLY UP TO 400 MILLIAMPERES (.4 AMP).
SYSTEM EXPANSION
There are other Niles switching devices available which are used to expand the switching capabilities of the SAS-1. Depending on the application, one or more of these expansion units may be needed. For example, by connecting the AC-2 Voltage Activated AC outlet to the SAS-1 you now have a signal-activated, switched AC outlet. Or, by connecting both an SPK-1 and an AC-3 to the SAS-1 you can switch 4 channels of speakers for surround sound and turn on any needed power amplifiers at the same time. The SAS-1 can have several of these expansion units connected to it, however, there is a practical limit of the number of units which may be connected.
A maximum of four expansion units may be connected to the DC control output of the SAS-1.
EXPANSION CAPABILITIES
The following expansion units are currently available for use with the SAS-1:
AC-3 – Voltage Activated AC Outlet Strip | AVS-2 – Voltage Activated Audio/Video |
| A-B Switch |
SPK-1 – Voltage Activated Speaker A-B Switch | RFS – Voltage Activated RF A-B Switch |
