Operating Options
NUMBER OF ALARM IMPULSES SELECTION
The selection of DIP switch 3 allows the definition of the number of presence impulses (two
or four) that must be detected by the sensor (in an interval of 8 seconds) before an alarm is
signalled. The choice must be made depending on the level of sensitivity it is required to give
the burglar alarm system; greater sensitivity is obtained with two impulses (DIP switch 3 OFF)
but also greater consumption and a consequent reduction of the autonomy of the batteries.
DETECTOR REMOVAL ALARM EXCLUSION
Selecting DIP switch 4 allows the activation or exclusion of the alarm linked to the removal
of the detector following the opening of the alarm contact located on the back of the
appliance itself.
OPERATING WITH A FLAT BATTERY
The detector signals flat battery when the batteries have reached the end of their operational
life. The flat battery condition is communicated to the control unit and displayed by making
the detector's yellow LED blink after each transmission. In flat battery conditions the green
LED is kept switched off independently of the LED switch-on selection.
INITIALIZATION PHASE
Following the first switch-on of the detector, the appliance requires approximately 1 minute
to stabilize itself and enter the operational operating mode.
The initialization phase is signalled by the continuous switch-on of the red LED.
OPERATING IN OPERATIONAL MODE
When operating in operational conditions the detector sends an alarm transmission when
the set number of impulses (two or four) are detected within a time interval of 8 seconds.
To save on battery consumption the detector inhibits itself automatically for 5 minutes after
each alarm transmission, after which the sensor is operational again and ready to signal
possible further alarms. An alarm transmission is represented by the red LED blinking; in
the case of a flat battery during the transmission the yellow LED is switched on immediately
after having made the transmission itself while the green walk-test LED is deactivated to
preserve the life of the batteries as long as possible.
