ACS 16.2 Installation and Operation Manual
DESCRIPTION
Audio Outputs
The ACS 16.2 provides two balanced low impedance stereo outputs. The output
level may be adjusted with internal single turn trimmers.
Silence Sensors
The ACS 16.2’s outputs have built-in silence detectors that monitors the sum each
stereo channel. The factory default delay is set at 10 seconds, with a threshold of -30
dB, while the restore time is set at 2 seconds. Upon silence detection the “SS-1”
and/or “SS-2” LEDs light along with the “SS1” and/or “SS2” relays will activate for
the duration of the silence. Serial data is also sent on the loss and restoration of audio.
The sensors may be programmed for:
• Silence sense threshold. The audio level below which is consider silence. This
may be set to -20 dBu, -25 dBu, -30 dBu or -35 dBu.
• Number of seconds of silence that must be present before an alarm state is
reached (Acquire delay.)
• Number of seconds that valid audio must be present before an alarm state is
cleared (Restore delay).
PIP (GPI/Trigger)/Remote Control Inputs
The ACS 16.2 has 16 status inputs that may be configured for PIP (“triggers”) or
remote control operation. The status inputs accept momentary contact closures to
ground, open collectors or TTL/CMOS input logic levels.
Open Collector Status Outputs
The ACS 16.2 provides sixteen open collector status outputs. The status outputs
may be configured to operate in one of three modes:
• The status outputs follow the associated channel.
• The status outputs a one-second pulse when the associated channel is selected.
• Software control
Relay Outputs
The ACS 16.2 contains eight SPST (normally open) relays. Each relay may be
latched on, latched off or momentarily turned on using serial commands. The
“pulse” time may be set from 100 msec to 9.9 seconds. The default pulse length is
one-second. Alternately, the relays may be set for “MPX” mode. In the “MPX” mul-
tiplex mode, the relay follows the associated input channel assigned to output two.
