Resetting Air Conditioning Controls
Overview
Indication
Resetting
The 4100ES may be used to control building air conditioning systems during a fire alarm.
During the management of the alarm, it is often desirable to be able to delay restoring the air
conditioning system to normal operation, e.g., to clear smoke even after the alarm conditions
have been cleared.
The A/C RESET control allows this delayed restoration.
When a zone alarm occurs, among the other alarm indications, the A/C AUTO indicator lights
to show that the 4100ES has taken control of the air conditioning system. This operation
remains in effect even after all alarms have been cleared and the 4100ES system has been
reset and is back to normal.
Before the A/C AUTO operation can be reset, all alarms must be acknowledged, and the
alarms must be reset to normal via the <SYSTEM RESET> key.
Once the system reset is complete, and there are no alarms present, the <A/C AUTO RESET>
key can be pressed to restore the air conditioning system to normal operation. The A/C AUTO
indicator will turn OFF.
