PRODUCT OVERVIEW
Texting has become an integral part of our lives. The ease and convenience combined with the time
stamping and logging of messages, makes it a great way to communicate with friends, family and
business associates. So why not enjoy the same benefits in your alarm dialer? That’s what the CM1
does for you.
When an alarm is triggered, the unit will text message up to recipients the alarm message in
English, as you have custom programmed it.
EXAMPLE
“PUMP STATION 3”
“HIGH LEVEL ALARM”
The CM1 uses 4 character codes to communicate but you only need to know one. “HELP?” The
response will contain a few tips and a link to our YouTube page with complete tutorials.
Contact it any time for status update. Text to it “DATA?” And it will send you a report on alarms and
other status flags. It will contact you every day with a report if you wish.
The CM1 has expansion capabilities and can be customized for specific applications and OEM
needs. Private labeling is available. Optional expansion PCBs and capabilities will be rolled out over
time. Check in with us for updates or sign up for our newsletter from our website’s front page at

WIRING CONNECTIONS
Digital Inputs connections
The inputs are grouped together in two sets. CM 1
is the common for 1-4. CM 2 is the common for 5-
8. The must be used with DC voltage onl , 5VDC
-24VDC. The polarit can be either direction, as
long as there is a difference of potential between the
DI and the common, it will register as a closure.
Most of the time the commons are connected
together.
Connecting dr contacts to the digital inputs.
This example uses the 24VDC input terminals to
drive the dr contacts from the field.
Connecting a sourced input.
The common is negative. When positive is applied
to the input, the indicator on the main screen will
darken.
Connecting a sinked input.
The common is positive. When negative is applied
to the input, the indicator on the main screen will
darken.
Connecting the rela output.
This rela is a ver low wattage. It is intended to
bring on an indicator, provide an input to a PLC or
engage a small rela . See specification page 4.
POWER CONNECTIONS
1 AMP at 24VDC is suggested for an external
power suppl . Our plug in suppl is available when
ordering.

PROGRAMING

SMS AND PUSHBUTTON PROGRAMMING
The various parameters are split between local push
buttons and SMS messages. Some parameters are
more secure if the are adjusted at the CM18 onl .
Some parameters would be ver cumbersome to
adjust with up and down ke s onl . See the SMS
Codes quick reference for the SMS parameters. See
below for the local parameters.
USB PROGRAMMING
The USB port can be used instead of SMS messages
to program the SMS adjustable parameters from a
computer. A terminal program such as
H perTerminal is used. Contact us for details.
STATUS SCREENS AND NAVIGATION

The numerals below are just a legend. The R (□)
indicates that the rela is de-energized. The carrier
is shown as AT&T and the signal strength is shown
to be full. The unit is ARMED meaning read to
execute an alarm notification. Listening… means
the SMS communication is waiting for an incoming
message.
On the bottom right a Sigma character blinks to
indicate the CPU is running.
KEYS
The up and down ke s are used to increase or
decrease a value. The up ke might switch an off/on
value to on while the down ke will switch it to off.
