Field Deployment
Important: Ensure that CNS-4G and all Sensor batteries are at full strength!
Range Test Mode:
After turning the CNS 4G
“
on
”
with the power switch, it will go into a
5 minute Range Test mode. The RX Receiver
’s
RED
LED’s
will go on for 2 seconds then
turn off. Next install the CR1225 batteries in the IR-
904 Sensor. After the “booting up”
,
the Sensor will go into a Range Test mode and transmit an outgoing signal to the CNS-
4G every couple of seconds. The LED’s on the
sensor will blink, and the
RED LED’s
on
the RX Receiver will blink as they receive incoming signals from the sensor. This verifies
that the CNS-4G is within range and receiving signals from the sensor. If the distance
between the Sensors and CNS-4G exceed the RF transmission output from the Sensor,
the
RED LED’s
on the RX Receiver will become erratic or stop blinking. After this Range
Test period, the CNS-4G will automatically go into
Alarm Mode
and the Receiver
’s
Blue
LED’s
and
Green LED
’
s
will only come on when the CNS-4G receives a sensor alarm
signal.
Important: Make sure to read the User Manual for the IR-904 Passive Infrared
Sensors.
The CNS-4G is designed to accept any number or type of sensors, but all sensors must
have an ID-1 or ID-2. The CNS-4G will not
accept any other Sensor ID’s other
ID-1 and
ID-2.
When a sensor sends an alarm with an ID-1 or ID-2, the CNS-4G will receive the alarm,
connect to the cell network and send the associated Alarm ID and customized SMS text
message. This usually takes about 45 seconds, but can take up to 2 minutes depending
on cell strength and traffic. Even in areas with poor cellular coverage, the SMS text
message will eventually go through. This is one of the advantages of using SMS text
messaging.
