8 Connection of External Signals

8.2 All Stop Input

You can stop all connected units automatically by connecting external signals (for example, from
re-alarm detectors.)
All stop input is available only for managed ("target") units. It does not affect units which have been
designated as not managed ("Not target") or individually operated ("Indiv Op").
1) Input location
The communications connector panel on the side of the Intelligent Controller or on an optional
communication adaptor connected to the Intelligent Controller:
DI1 (No. 17), DI-COMM (No.16)
2) Operation
While the input is asserted ON, a stop signal is sent periodically (once per minute) to all indoor
units.
3) Display
This message disappears when normal status is restored.

8.3 All Start Input

You can start all connected units automatically by connecting external signals.
All start input is available only for managed ("target") units. It does not affect units which have been
designated as not managed ("Not target") or individually operated ("Indiv Op").
1) Input location
The communications connector panel on the side of the Intelligent Controller or on an optional
communication adaptor connected to the Intelligent Controller:
DI2 (No.18), DI-COMM (No.16)
2) Operation
When inputting ON from OFF, the operation signal will be transmitted to all the indoor units.
When both "All stop input" and "All start input" are set ON simultaneously, only "All stop input" is enabled.
