Program Flow Diagram
The diagram below shows all the programming options.
Programming is performed by inserting a link between the A and K terminals (or by
having the detector wired in place) and holding down the Push Button when
switching on the power.
The red led on the PCB flashes at 1 second intervals. When the required number of
flashes is seen (see later for the list of possible choices) the button is released to
store the first value. At this point the led comes on for five seconds to confirm the
value is stored.
The led then starts flashing again, and this time the button needs to be pressed to
store the second value.
Once the two values to be stored are entered, the led flashes 10 times rapidly, and
the module starts operating.
Most values entered can range between 1 and 255 (see below for limits). If more
are seen, or the programming is aborted by switching off, then the programming
must be repeated.
