NOTES:

2. The operation sequence indicated here is not complete. Provide other operations in accordance with NFPA 72 and Contract documents.

3. This sequence of operations are considered to be minimum.

4. Operation of the abort switch shall prevent activation of the clean agent and opening the pre-action valve.

1. Activation of the second smoke detector or manual release station in room 114 will result in AHU shut-down and power shut down. Activation of a second smoke detector or manual release station in other rooms will only close the smoke dampers serving that room.

5. Operation of the second smoke detector or manual pull station shall initiate a 15 second delay (adjustable) after which the clean agent shall discharge and the pre-action valve shall operate. Activation of the abort switch shall prevent discharge as long as the abort switch (deadman) is activated within the 15 second time-frame. The abort switch will not override the manual pull station.
