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
flashes 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 dependent on the receiver location and transmitters
communicating with it. 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 receiver.
Signal Level is a measure of how loud 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
