Overview
Each transmitter (black unit) monitors a sensor. When the sensor detects a change
(door opens or closes), it will transmit this information to one or more receivers
(white units).
Each receiver will then beep
1
(once for door closed and twice for door open).
When all doors are closed, a green light will stay on. When one or more doors are
open, an amber light will blink.
Each transmitter has a unique identification number which it transmits along with
the door and battery status. Only those receivers who know this number will
respond to this transmitter.
To make a transmitter “known” to a receiver is called “programming”.
When transmitter(s) and receiver(s) are bundled together and purchased as a set,
then each receiver “knows” each of the transmitter(s). Simply put in the batteries
and install the units.
If a transmitter is purchased separately to be added to an existing system, then
“programming” will need to be done. See page called
Programming Units
.
