SmartSwitch™ TD812 Dual-Input Transmitter
The battery-powered Isaacs TD812 Standard Power transmitter monitors two sets of dry contacts and transmits the contact state (open or closed) in uniquely coded radio signals to its mated Isaacs receiver(s).
The mated receiver(s) detect the TD812 transmitter signal and uses it to control relay output(s).
In addition to the change-of-state signals, the transmitter sends periodic status signals to allow full supervision of the system.
