User's Manual

If the unit is equipped with a motion sensor or accelerometer the unit is programmed to monitor
the activity of the sensor. In the event that the conditions arise that would allow the processor to
start a count down sequence to an alarm the following would occur.
A period of inactivity would be selected when programming the device. This could be typically 30
seconds. If no activity is recorded within this period the onboard warning beeper would begin to
emit an audible warning of an impending alarm. This would have another time base selected,
typically 15 seconds. At the end of the 15 seconds the transmitter would automatically initiate its
alarm transmission sequence which will not stop until manually reset. If at anytime during the
initial countdown or during the audible countdown the sensor picks up activity commensurate with
normal activity the unit will auto reset and no transmission would occur.
Typical applications and duty cycles for this application
Heartbeat transmissions will last for a maximum of 600 milliseconds but will more typically send
for less than 200 milliseconds. These would be repeated automatically once every 10 to 60
minutes depending on the application. These signals would be the normal operating cycle for the
transmitter. The only time that an alarm signal would be generated would be where a life-
threatening situation arose and then the unit would only transmit until reset. The automated
signals would expect to be sent once every 10 seconds and typically last no more than 600
milliseconds. If a response to an attack were to take 2 minutes to respond to then the operative
would be exposed to 12 transmission bursts of 600 milliseconds.
