(a) The RRM02 can be connected to any available Router inputs.
y
The Router inputs are to be programmed as 'Miscellaneous Input'.
y
Miscellaneous inputs used by multiple RRM02 units are to have the same priority as each other and be set to
'No Chime'.
(b) RRM02 serial data not connected to the Router.
The BUSY LED will not operate, and the ACTIVE LED will only indicate that the PTT button is being held down.
(c) VAR4/VAR12/VAR20, VAR8, and VAR8-ACU: the power supply from the Router input should not be used.
DAU: the power supply from the Router input can be used.
(d) The Router can be either a rack mounted or a wall mounted ASL PA/VA system.
y
Rack mounted system: VAR4, VAR12, VAR20, or VAR8
y
Wall mounted system: DAU (Distributed Amplifier Unit)
Please refer to the user documentation specific to your Router for pinout details.
(e) Audio inputs from RRM02 units are to be routed to an intermediate Router output (any available), which is then
connected to any available Router input. In this example, Output 1 and Input 3.
This intermediate Router input to be programmed as 'Miscellaneous Input', with chime programmed. This audio
input is then routed to the required audio zone output(s).
(f)
Any available Router intermediate digital inputs, connected as a simple contact closure to ground.
The contacts to be programmed to route the appropriate audio inputs from the RRM02 units to the intermediate
Router output which will be fed back into the Router.
In this example:
y
Contact 1 routes Input 1 to Output 1 when contact is closed.
y
Contact 2 routes Input 2 to Output 1 when contact is closed.
(g) Router output(s) serving the required audio zone output(s).
In this example, Output 2.
(h) Refer to the BMB01 Remote I/O Unit user documentation for connection details.
(i)
Any available BMB01 digital inputs, connected as a contact closure to a supply, which is provided by any available
BMB01 digital output configured for Busy Indication.
y
The digital input is to be programmed to route the intermediate audio input to the required audio zone
output(s).
In this example, Digital Input 1 routes Input 3 to Output 2 when the contact is closed.
y
The digital output is to be programmed for a Busy Indication when the Router inputs connected to the
multiple RRM02 units are routed to the intermediate output.
In this example, Digital Output 1 indicates Busy when audio Input 1 or audio Input 2 is routed to Output 1.
Cable screen tails to be connected to system ground and to be < 3 cm.
