master mode. When the switch is released it will default back to the
Listen or Speaker mode, allowing the user to receive any messages
transmitted back to it. The output amplifier offers full short circuit
protection and over heat protection.

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, pull-
ing 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 Mas-
ter and the Slave unit. Paragraph G. WIRING DIAGRAMS contains
wiring diagrams of typical intercom configurations.
