The Single Station Remote Alarm is capable of operating at either 120VAC or 220VAC depending on which
wall mount power supply it was ordered with. It is capable of providing operating status for the left and right
banks of one CONCOA Autoswitch/Switchover system. The Single Station Remote Alarm provides power to
the Autoswitch/Switchover to operate the status indicator lights and the pressure switches.
An Autoswitch product that is configured with the alarm option is equipped with two pressure switch gauges,
two sets of status indicators, and a power status indicator. A pressure switch gauge and one set of status indicators
are used to monitor and report the state of the pressure for each side of the Autoswitch. A Switchover system
has only the pressure switch gauges.
The front panel of the Remote Alarm consists of four (4) status indicator lights, an "Alarm Silence" button, and
an audible Alarm. See Figure 1. In addition to the front panel, the left side of the Remote Alarm has a power
jack connector where the power supply cable is connected. At the bottom of the Alarm are two (2) connectors
where the Autoswtich/Switchover and Output Devices are connected.
The Single Station Remote Alarm controls one (1) set of relay contacts that are brought to the Output Connector
so they may be used to control an external device.
The status indicator lights are organized into paris representing the Left Bank and Right Bank of an Autoswitch/
Switchover System. When a system is operating normally the status indicator light will be green. If the pressure
should drop below the preset value of the Autoswitch/Switchover, the audible alarm will sound and the light
corresponding to the specific Bank will turn from green to red. When this happens, the output relays will activate.
It is sometimes desirable to silence the audible alarm prior to the alarm condition being fixed. Pressing the
"Silence" button will accomplish this. The status indicator lights and the relays will remain activated until the
alarm condition is corrected. If the second bank on the same Autoswitch/Switchover generates an alarm while
the first Bank is still in an alarm condition the other status indicator light in that system will turn from green to
red and the audible alarm that was previously silenced will sound again.
Correcting the low pressure condition will return the status lights back to green, and deactivate the relay.
