Six LEDs display receiver operation and activity.  Refer to the table below as required.

PNL RX

Flashes yellow to indicate data is being received from the panel.

PNL TX

Flashes green to indicate data is being sent to the panel.

STATUS

Steady red to indicate memory upload.  Off when upload is complete.

RF RXD

Flashes yellow to indicate data is being received from a transmitter.

RF TXD

Flashes green to indicate data is being sent to a transmitter.

DMP 1100 Series transmitters provide Two-way (transmit acknowledge) operation.  This advanced data protocol 

allows each transmitter to confirm that each of its messages (alarm, checkin, tamper, low battery) are received 

and acknowledged by the 1100 Series receiver.  The confirmation is indicated visually by use of an LED on each 

transmitter.  This Survey LED should be used during installation to test each transmitter for proper operation.  A full 

definition of the Survey LED follows.
The red LED on an 1100 Series transmitter turns on when the processor wakes up to send a message.  Then after a 

series of communication steps are completed (successful or not), the LED turns off when the processor goes back 

to sleep.  99.9% of the time the processor is asleep in normal operation.  The following list summarizes various 

indications that can be observed on the LED and a definition for each.  Note this is for a single message.  Example, 

pressing and holding the tamper switch. 

Single 1/16 second flash 

•  Processor wakes up 
•  Transmitter receives immediate synchronization from receiver 
•  Transmitter transmits 
•  Transmitter receives immediate acknowledgement from receiver 
•  Processor goes to sleep 

•  Processor wakes up 
•  Transmitter receives synchronization from receiver - possibly not immediate 
•  Transmitter transmits 
•  Transmitter receives acknowledgement from receiver - possibly not immediate 
•  Processor goes to sleep 

•  Processor wakes up 
•  Transmitter never receives synchronization from receiver, or might receive synchronization 
•  Transmitter transmits if synchronization was received 
•  Transmitter never receives any further data from receiver 
•  Processor times out and goes to sleep 

•  Processor wakes up 
•  Transmitter receives synchronization from receiver 
•  Transmitter transmits 
•  Transmitter receives data from receiver, but not a valid acknowledgement 
•  Processor briefly goes to sleep 
•  Entire sequence is repeated, each short flash indicates a cycle
