• 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 station
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.
Use normally open type switches to activate the logic inputs. Connect the
switches as follows (Figure 7 on page 1-4):
• Logic input #1—pins 4 to 5 (pin 4 = ground)
• Logic input #2—Pins 11 to 12 (pin 11 = ground)
Note:
Do not apply external voltage to the logic inputs.
Mute Relay Contacts
The mute relay is activated whenever any talk selector is activated at the station.
The mute relay is commonly wired such that whenever it is activated, the volume
of the monitor speaker in that room is decreased (muted). See Figure 7 on page
1-4.
Both normally open and normally closed contacts are provided. They are rated at
1 Amp at 24 VDC. This relay is not designed for switching mains AC line
voltage. To switch an external device running on mains AC line voltage, use an
external relay (or other switching mechanism) activated by this relay.
Programmable Relay Contacts
Each station includes a relay controlled by the system program and independent
of the local station 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 station in the system, including a direct-inward-access caller.
Figure 7 on page 1-4 shows the wiring of the relay contacts to the Miscellaneous
connector.
Both normally open and normally closed contacts are provided. They are rated at
1 Amp at 24 V DC. This relay is not designed for switching mains AC line
voltage. To switch an external device running on mains AC line voltage, use an
external relay (or other switching mechanism) activated by this relay.
