The ICR-116 Intercom Switching Relays are
ruggedized intercom panels for use in harsh
environments, such as correctional facilities.
The ICR-116 provides high quality audio
communication with complete flexible control.
The unit has connections for 16 remote
intercom Stations, each with their own Speaker
and Call-in Switch. The Call-In and Relay
Control connections are each 24-pin ribbon
connectors.
A jumper option supports either Sinking or
Sourcing Relay Drivers. Another Jumper Option
allows the Call-in switches to be referenced to
the Logic or Relay Power Source.
For convenience, all of the ICR-116
connections are connectorized. Remote
Stations connect via 4-pin 0.1” Spring Cage
Euro-Style Barrier Strips. Connections for
Power, Intercom Amplifier, and Paging
Amplifier, are Screw Terminal Euro-Style
Barrier Strips.
Associated with each Station Selection Relay is
a Station Status Indicator. The Station
Indicators show the Technician which relay or
relays are active. The indicators are intuitive,
and easily interpreted. Each Station Indicator is
either Off or On. When an Indicator is Off, there
is no activity with that station. When an
Indicator is On, that Station is selected for
Communication.
Another product, the ICR-116EX, has a multi-
pin connector on the opposite side of the PCB
for access to the normally closed relay
contacts. By using the “Back Contacts”,multiple
masters orpriority switching can be achieved.
In applications where a more powerful Paging
Amplifier is required, a Paging Relay(s)
connects Selected Station(s) to a Paging
Amplifier Output, such as the Tech Works PA-
402.
