SLAVE MODE:
Some applications may require that the intercom constantly transmit
(i.e. act as a microphone) as opposed to constantly receive (i.e., act as a
speaker). To accomplish this the intercom must be switched into the Slave
(Push-to-Listen) mode.
Disconnect power to the intercom before any installation,
maintenance, or configuration changes are performed.
Move the J3 jumper block on the P.C. board from the MAS to SLA
position (see Figure 1). This can be done using long nose pliers, pulling the
block off the "MAS" and center position and placing it on the "SLA" and
center position.
When hooked to a Master unit it may be necessary to override the
Slave unit in order for the Master unit to be able to transmit. The remote
control and ground lines must be connected between the Master and the
Slave unit. Paragraph G. WIRING DIAGRAMS contains wiring diagrams of
typical intercom configurations.
