Style 6 Loop Operation
This LED indicates that the AIM -200 has been programmed for redundant
communications loop operation. Select or deselect for the entire loop by
pressing the control switch.
Note 1: To function as a redundant communications loop, the AIM - 200
loop must be wired in accordance with Figure 12.
Note 2: An isolated -redundant circuit is a variati on of a redundant circuit
(see Figure 13). If wired as an isolated -redundant
communications loop, the AIM -200 should be programmed for
redundant circuit operation.
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.
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 devices. 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 pressing SKIP; or
normal operation by removing the PK - 1 key.
