4.2 Auto-Program Mode
Auto-Program is used when a system is first installed, or when device additions or deletions
are necessary. It determines the number, address and type of devices to be programmed by
polling the addressable loop. The AIM-200 determines which devices have been physically
installed on the loop and compares this information against the program stored in memory.
If a particular device responds differently, the AIM-200 displays the new address and type. If
accepted by the programmer, the information is stored in the non-volatile memory. Certain
other parameters are pre-selected by the AIM-200, such as zone assignment and detector
sensitivity, with the installer given an opportunity to change those parameters as desired.
Entering Auto-Program Mode
Once in Auto-Program mode, the AIM-200 turns off all LEDs, places a flashing “AP” on the
digital display, and begins polling all 198 possible addresses. It stores the address and type
of each device as found. It then compares each new address/type with the old information
stored in its memory. If the old and new address/type match, the AIM-200 proceeds to the
next address, and repeats. This process could take several seconds to complete all de-
vices. Only removal of the PK-1 key can abort the process.
If a mismatch is found between the actual devices installed on the loop and the information
in memory, information about the actual device is displayed. The operator may accept the
new device by pressing ENTER, or reject the device and retain the information that was in
memory by pressing SKIP. Mismatches include an installed device that is not in memory, a
non-existing device that is in memory, or a different Type code.
After any mismatches are accepted or rejected, the AIM-200 displays a count of the number
of programmed detectors, alternating with a count of programmed modules. The operator
may exit to: Program Edit mode by pressing ENTER; Auto-Program mode (repeat) by press-
ing SKIP; or normal operation by removing the PK-1 key.
