SATEL XD-2 3
Magnetic contact
Alarm output will turn on after:

moving the magnet away from the detector (opening the window or door),

opening the SNS input.
Shock detector
Alarm output will turn on after:

detecting a shock caused by a single strong impact,

detecting a defined number of minor shocks caused by a series of light impacts,

opening the SNS input.
Shock detector and magnetic contact
Alarm output will turn on after:

detecting a shock caused by a single strong impact,

detecting a defined number of minor shocks caused by a series of slight impacts,

moving the magnet away from the detector (opening the window or door),

opening the SNS input.
Water flood detector
The alarm output will turn on approximately 1 second after the water level reaches the height
at which the probe contacts are installed. The alarm output will turn off a few seconds after
the water level drops below the height at which the probe contacts are installed.
Additional alarm output
When the detector works as a shock detector and magnetic contact, you can use 1 or 2
alarm outputs. If you enable the two output mode:

the NC output will indicate alarms from the magnetic sensor and the SNS input,

the S output will indicate alarms from the shock sensor.
When the two output mode is disabled, all alarms will be indicated by the NC output.
You can enable / disable the two
output mode by using the DIP switch (see: “Two output
mode enable / disable
”).
Supply voltage control
If the voltage drops below 9 V
(±5%) for more than 2 seconds, the detector will signal
a trouble condition. When the trouble condition is present, the NC alarm output and the LED
indicator are ON. If the two output mode is enabled in the shock detector and magnetic
contact, the trouble condition is indicated by the NC and S outputs. The trouble is indicated
for as long as the condition is present.
LED indicator
The red LED indicates:

minor shock detected (does not reach the sensitivity threshold)
– short flash,

alarm triggered by a shock
– ON for 2 seconds,

alarm triggered by opening the window or door / opening the SNS input / detecting water
flooding
– ON for as long as the condition that triggered the alarm is present,

trouble
– ON for as long as the trouble condition is present.
