Messenger 570’s phone jacks. You can attach a standard telephone into the other jack. It is recommended that
you use this standard telephone to check the phone line for dial tone and the ability to make incoming and
outgoing phone calls.
Cellular Phones
The Messenger 570 will also work with North American analog cellular phones equipped with a dial-tone
adapter. Support for GSM and PCS cellular phones is planned for the future. Contact technical support for
details.
Low-Orbiting Satellites
The Messenger 570 works with an optional satellite transceiver capable of providing cost-effective
communication from virtually any location on Earth. Contact technical support for details.
Connecting a Power Source
The Messenger 570 is factory configured to operate on 110 VAC 50/60 Hz OR 220 VAC 50/60 Hz. It can also
operate from 12 VDC.
AC Operation
Plug the Messenger 570’s power cord into a properly grounded (three-wire) electrical outlet. The power
required by the Messenger 570 is 20 watts plus the wattage of the load (if any) attached to the “AC Switched
Output” connector.
DC Operation
Connect the positive lead of a 9 to 15 VDC source to the “DC IN” terminal and connect the negative lead to the
“Common” terminal.
IMPORTANT: When using DC power, the Messenger 570’s AC power cord MUST be disconnected AND its
backup battery MUST be disabled by removing the jumper from between the “BATT OUT” and “DC IN”
terminals.
Solar Operation
The Messenger 570 can be powered by a properly sized solar panel. Contact technical support for details.
Backup Battery
The Messenger 570 system has an internal rechargeable battery that maintains full operation in the event of a power
outage. This battery must be enabled when the unit is put into service and disabled when taken out of service. All
information programmed into the Messenger 570 system will be retained whether or not the battery is connected to
the system.
NOTE: An auxiliary DC power output on the Messenger 570 system can be used to power external sensors and
accessories. It provides 12 volts DC (nominal) at up to 200 mA. This power is taken from the Messenger 570
system’s backup battery and will provide uninterruptible power, even during a power outage.
