Signal Level And Margin - Bosch Radion B810 Reference Manual

RADION receiver SD
Motion walk test
Remove and replace cover to activate a 90-sec Walk Test Mode. During this Test Mode, any
activity in the sensor's coverage pattern will cause a transmitted alarm and LED activation.
Each alarm will also extend the Test Mode for an additional 90-sec. Walk Testing should be
done across the coverage pattern. The edge of the coverage pattern is determined by the first
flash of the LED. This may change slightly depending upon the sensitivity setting. Walk Test
the unit from both directions to determine the pattern boundaries. Although generally not
required, if masking is desired, the lens diagram shows the appropriate areas to be masked.
Use an opaque material (such as, electrical tape) to mask the desired areas.
Final test
While the detector is in the Walk Test Mode, turn on all heating and air conditioning sources
which would normally be active during the protection period. Stand away from the sensor and
outside the coverage pattern and watch for alarms. After setup and tests are completed, and
there has been no activity in the sensor's coverage pattern for approximately 90-sec, the LED
will flash to indicate that the Walk Test mode is ending.
Maintenance
At least once a year, a walk test should be performed to verify the range and coverage for
proper operation.
Magnet walk test
Perform a magnet test to ensure proper functionality of the door and window contacts.
Magnet testing can be performed by opening or closing the door/window in which the magnet
is installed. In this test, you are verifying the distances of which the magnet engages and
disengages the transmitter.

Signal level and margin

The signal level and margin (ambient signal) of the RADION system is dependant on the
location in which the B810 receiver and transmitters communicating with it are installed.
Installing the receiver in an environment that has a lot of radio transmitter communication or
other exterior disturbances, may reduce the receiver signal strength and margin signal of the
B810 receiver.
Signal Level is a measure of how loudly a RADION receiver is hearing a message from a
RADION transmitter; this value is displayed as a percentage with a range of 0% - 99%.
Signal Margin is a measure of how well a RADION receiver is hearing a message from a
RADION transmitter given the current ambient noise levels, or 'white noise' at the receiver.
This value is displayed as a percentage with a range of 0% - 99%.
The concept of signal margin can be related to two people conversing in a room; when the
room is quiet they hear each other clearly and the "signal margin" would be very high. In a
noisy room they would not be able to hear each other as clearly and the "signal margin" would
be much lower. When the signal margin is low enough conversation is no longer possible.
The RADION receiver will continually monitor the signal level of every system transmitter and
report an interference trouble (sometimes called Jamming) if the signal margin of a
transmitter is reduced to the point where communications may be lost.
To ensure reliable system communications, the signal level and margin of every transmitter,
including repeaters, should be tested and verified to be reporting "good" at the time of
installation and in the unlikely event of a interference trouble report.
