Setting Up an Instant Alert
A useful application for the VoiceLift Microphone is the instant alert. By connecting
an MLC 104 IP Plus control panel to the VLR 102 receiver’s relay port, you can set
up e-mail alerts to be sent out when both parts of the microphone’s Volume button
are pressed and held for 3 seconds.
To set up an instant alert, follow these steps:
1.
Wire one of the provided two-pole captive screw connectors to one end of a
communication cable.
Insert the red wire in the connector’s left slot and the black wire in the right
slot.
2.
Plug the communication cable into the receiver’s Rly (relay) port. Ensure that
the red wire is connected to the NO (normally open) port and the black wire is
in the C (common) port.

If the MLC and the PoleVault switcher are using separate power supplies,
ground the receiver’s Rly port C pin to the receiver using a jumper between the
C pin and the ground (
_
) pin on the contact input (CTC), the auxiliary input
(Aux In), or the RS-232 port.
