Use a timeout value that is greater than the one used by the device
itself to allow automatic re-arming upon detection of the device's own timeout
response. This allows maintenance of a near-continuous armed status.
Using a value less than the device's timeout may result in a timeout
event or exception if a check is not inserted soon enough. A suggested starting
value is 11000 since a common device timeout is 10000. Using a value that
is too much greater than the device's own timeout value will cause unnecessary
delays in the detection of faulty conditions.
