SPECIALOUTPUT FUNCTIONS
In normal operation the output relay has temporary function, i.e. it is energized on a few instants after pressing
the control key (delay caused by code recognition), it is de-energized 300 mS after a key has been released.
Some special functions are available for output relay conduct.
STEP-BY-STEPFUNCTION
The relay is activated by pressing the remote control key and remains activated until the key is pressed again.
TIMER FUNCTION:
The relay is activated by pressing the remote control key and remains activated until the preset time has ela-
psed. The period is timed restarts every time the key is pressed and can be disabled early by pressing the key
for at least 3 sec.
BURGLAR ALARM FUNCTION
This function is combined with outputs 1 and 2. When key 1 is pressed, the step-by-step function will be ena-
bled on channel 1 (used to enable / disable burglar alarm function). Besides having the normal operation linked
to key 2, channel 2 is briefly enabled once when channel 1 changes from OFF to ON and twice when chan-
nel 1 changes from ON to OFF.
An visual warning or alarm can thus be connected to channel 2 to warn that the burglar alarm has been trig-
gered off or disabled.
