Operation – Detailed Outline
OPERATION – SEARCH
When the host is turned on it searches for FOBs.
As soon as at least one FOB is registered, the system will be armed.
If the host finds a FOB during its search, it will register the FOB and
light up its associated LED.
If the host finds all four FOBs it will stop searching
After 3 minutes of searching, the host will stop searching. If no
FOBs have been found it will turn itself off.
FOB SURVEILLANCE OPERATION
FOB and host will communicate every 0.5 seconds
If the host misses two communications from the FOB, it will set itself
into ALARM mode
If the host gets an emergency alarm request from the FOB, it will set
itself into ALARM mode
CHARGE & ACTUATOR (HARDWARE) SELFTEST
The host will monitor the capacitor voltage at the actuator to test
charger circuit and presence of the actuator coil.
If voltage stays below 90V for greater than 30 seconds, it will be a
fault
If the Voltage is greater than 106V for 3.5 seconds, it will be a fault
If A/D converter self-test fails, it will be a fault
ALARMS AND FAULTS
