Management of alarms generated by shocks/vibrations
The detection of the alarm generated by impulses caused by shocks or vibrations can be configured as follows.
Single pulse detection
The alarm is generated by the detection of a single pulse exceeding the set threshold.
Multiple pulse/sum of vibrations detection
The alarm is generated by the detection of at least one of the following two conditions:
I. When
3
pulses are detected in a time interval of less than
20
seconds
.
II. When the accumulation of vibrations detected in a time interval of less than
2 minutes
exceeds the set threshold.
The modes described are determined by jumper JP3:
If the jumper is ON (the jumper is inserted on the two pins):
Single pulse detection
(default setting)
If the jumper is OFF (jumper removed or "arranged" on a pin):
Multiple pulse/sum of vibrations detection
Sensitivity adjustment
Jumpers JP4 and JP5 can be used to determine the sensitivity required to generate a shock or vibration alarm. See the
following table:
Battery
The device is powered by a CR123A 3 V lithium battery and can indicate when the battery is flat. When the battery charge is
low, the device sends a signal to the control unit together with the normal transmissions.
When the battery is flat, the device does not work and the LED blinks every 4 seconds.
The battery is pre-installed at the factory with the insertion of an insulating element. Remove the insulation from the battery to
activate the device.
Tamper protection
The tamper switch protects the device from tampering attempts or attempts remove it from the installation surface.
Supervision
In normal operation, the device transmits a supervision signal to the control unit at regular intervals during normal operation.
The control unit generates a supervision alarm if the control unit does not receive the device signal within the predetermined
time.
Test
Whenever the Test button is pressed, the device transmits a signal to the control unit to test the radio range and
activates Test mode for 3 minutes.
In Test mode, the LED lights up whenever an alarm is generated.
Test mode is extended by 3 more minutes if the Test button is pressed again.
Preparation
Step 1: Remove the battery insulation.
Step 2: Enable the learning function on the control unit (see the respective manual for more details).
Step 3: Press the Test button on the device to send a signal to the control unit.
Step 4: If the control unit receives the signal correctly will respond by emitting beeps. Refer to the manual of the control unit
to complete the learning process.
Step 5: After the device has been learnt, set the control unit to "Walk Test" mode, by holding the device in the desired
position and press the Test button to check that it is within the wireless range of the control unit.
Step 6: After having checked the correct position of the device, proceed with the installation.
