Universal Remote Control MSC-400 Programming Manual page 87

Relay +12V Normally Open
NC (Normally Closed)
1 For a device that provides voltage for use with a switch closure:
a) Connect the +V terminal on the controlled device to the Relay 1 NC terminal on the MSC-
400 Rear Panel, using one of the included three-pin plug-in connectors.
b) Connect the ground terminal on the controlled device to the relay 1 COM terminal using
the same plug-in connector.
2 For a device that requires external control voltage:
a) Connect a jumper (24-14 AWG two conductor stranded wire, typical) from the 12V out ter-
minal on the MSC-400 Rear Panel to the Relay 1 COM terminal as shown in Normally
Closed (Relay 2 Shown).
b) Connect the Relay 1 NC terminal to the +V terminal on the controlled device.
c) Connect the GND terminal on the controlled device to the GND terminal on the MSC-400
Rear Panel as shown.
When a properly programmed MSC-400 compatible remote sends an On command (latching, press and hold
or timed), Relay 1 will Open and the controlled device will respond with an interruption to its normal action.
When the Off Command (latching, press and hold or timed) is sent, RELAY 1 will close and the controlled
device will respond by resuming its normal action. Wire Gauge: 24-14AWG two-conductor stranded; Max
Load: 30V; .5A.
NOTE - Latching commands initiate an action until another command is sent. Press and hold and timed com-
mands perform the specified action only for as long as the button on a remote is held (press and hold) or for
the duration of the switch closure (timed).
Relay 2
1 Follow instructions as detailed in Relay 1 using the Relay 2 terminals.
12V Out
1 See Sections: Connections Relay 1/Relay 2 above for use with the MSC-400 internal relays.
12VDC
1 Connect the included 12VDC 3.5A power supply after all system connections have been made and
confirmed. Polarity: Pin=+12V; Sleeve=GND
