I. Introduction
The Advantage Controls RA-6 Remote Alarm unit is designed to communicate an alarm or abnormal
condition of operating equipment to areas outside the equipment area. The unit is comprised of a
base unit and a remote unit. The RA-6 has 6 input channels and each channel can be individually
congured in the base unit to monitor dierent types of input signals, such as dry contact, AC/
DC voltage or open collector transistor. These signals can be from virtually any source such as
conductivity/resistivity monitors, level switches, pressure switches, limit switches, motor contactors,
etc.
The base unit provides power for the remote unit and has jumpers for conguring the input channels.
Channels 1-4 have a xed 1-second delay and channels 5-6 have either a xed 1-second delay or
an adjustable time delay. The remote unit has a green power on LED, a red alarm LED and red
individual alarm LED’s. An audible alarm is provided with an alarm silence switch. The alarm silence
can be maintained or timed. A power failure alarm is incorporated into the remote unit and also an
optional alarm relay output..
II. Installation
The base unit is normally mounted in close proximity to the equipment to be monitored. The base unit
requires 120 VAC power, 2 conductors for each channel input used and a single multiconductor cable for
connection to the remote unit.
Wire the 120 VAC power to the power in terminals. Connect the 2 signal wires from each source to be
monitored to the desired input channel. Any channels not used can be left open. Refer to the supplied
drawings for each unit for wiring information.
The base unit jumpers must be programmed for the type of signal to be applied to each channel.
WARNING: The unit can be damaged if the wrong signal type is applied to a channel. The channels are set
as 28-120 V(AC or DC) by default. Refer to the jumper settings drawing for jumper settings for each channel.
If an adjustable delay is desired for channels 5 or 6, the corresponding jumper must be moved to enable the
adjustable delay.
The remote unit can be mounted in any convenient location where it can be seen and heard by operating
personnel. The multiconductor cable to wire the base to the remote unit must have 2 wires for ground and
12V power and 1 wire for each channel used. For example, if 4 channels are used, a 6-conductor cable can
be used. To wire the remote unit, remove the 4 screws holding the cover in place, pull the cable through
the cord grip connector in the bottom of the box and connect the wires to the terminal strip as shown in the
drawing. If required, set the jumpers for the power fail or alarm recycle features.
NOTE: If the RA6R remote unit is used with a base unit that has the recycle circuitry installed, the recycle
jumper on the base unit must be placed in the o position. Base units that do not have the recycle circuitry
installed must only be used with the RA6R remote board for the recycle function to operate properly.
