• Speaker OFF—turns off the panel speaker, disabling all audible
output from the panel.
• PTT: Activate All Talk Keys—implements a push-to-talk function for all
talk selectors. When the logic input is active, the panel operates
normally. When the logic input is deactivated, all active talk
selectors are disabled. Any controls (relays, etc.) assigned to the
labels are activated or deactivated along with their assigned labels.
The LED indicators associated with the active talk selectors
operate normally regardless of the PTT status. This input only
controls latched talks.
• Activate Talk Switch #1— equivalent to pressing the panel’s first
(leftmost) talk selector; a momentary and latching activation.
• Activate Talk Switch #2—equivalent to pressing the panel’s second
talk selector; a momentary and latching activation.
• Activate Listen Labels Button—equivalent to pressing the “Listen
Labels” button to display listen labels on any display expansion
panel (XPL-12 or XPL-22) connected to the panel.
• PTT: Activate Two-Way Radio Keys—implements a push-to-talk
function for all two-way radio talk selectors. When the logic input is
active, the panel operates normally. When the logic input is
deactivated, all active two-way radio talk selectors are disabled.
Any controls (relays, etc.) assigned to the labels are activated or
deactivated along with their assigned labels. The LED indicators
associated with the active two-way radio talk selectors operate
normally regardless of the PTT status. This input only controls
latched talks.
Programmable Relay
Each ICS-2003 panel includes a relay controlled by the system
program and independent of the local panel function. This relay can be
assigned to any label(s) in the system, which will activate whenever a
talk or listen is set to that label(s). If activating the relay is the only
action desired, assign the relay to a Control label. See the Eclipse
Configuration System Manual
for more details.
The relay can activate an external device, such as an applause light in
a studio, a cue light, or a security door lock. Any programmable relay in
the system can be activated from any panel in the system, including a
direct-inward-access caller.
Mute Relay
The mute relay is activated whenever any talk selector is activated at
the panel. The mute relay is commonly wired such that whenever it is
activated, the volume of the monitor speaker in that room is decreased
(muted).
