Roboguard 7
Minimising False Alarms
The Roboguard uses dual pyro-electric cells to look for changes in
movement, light and temperature in its field of view. It is therefore
extremely important that the guard is installed in a position that does
not inadvertently cause the guard to see changes, which could be
reported as false alarms.
Identifying false alarms:
1.
Situations where the guard is exposed to reflections of sunlight
reflecting off water or glass.
2. Situations where the guard is exposed to warm/cold thermals such
as a tar driveways.
3. Movement of the structure to which the Roboguard is attached.
4. Moving vegetation between the unit and a significant heat-source
(such as the sun).
5. Poor alignment of the sensor beams (see ‘setting up the beam
array for optimal performance’).
Steps in rectifying constant false alarms:
1.
Identify what is causing the false alarms.
2. Move the Roboguard to exclude the problem object/area, remember
the entire area doesn’t need to be covered, only such that you will
be alerted if someone enters this area.
3. Block off the desired beams to exclude problem objects, for
example large swaying palm leaves.
4. The sensor boxes may have moved during transport and will need
to be realigned to the middle position. (See ‘Setting up the beam
array for optimal performance’).
5. In some cases it is not possible to solve a problem with any of
these suggestions and the Roboguard needs to be reconfigured
(See the ‘Roboguard Configuration’ section).
6. Use dog biscuits to run dogs through the beam array in walk-test
mode to hear if the beams are set correctly.

Please contact your local Roboguard dealer if you are not able to
solve the problem.
