What is alarmStatusInputBitmap?
This OID represents the status of up to 15 external digital input sensors connected to an alarm card, where each bit shows whether an input is open (1) or closed (0). Network engineers monitor this to track the state of environmental sensors, door locks, or emergency switches connected to the device. For example, a value of 0x0102 indicates inputs 1 and 8 are open while others are closed.
