Single Zone Fire Condition
Upon receipt of a fire condition by activation of a detector or pull station, the Common Fire indicator will light and the
zonal Fire indicators will flash at around 2Hz. The fire and local fire relays will also operate and signal any systems to
which they are connected. Any annunciators connected to NAC1 and NAC2 will operate. If the zone that has activated
is contributing to the extinguishant release sequence, the First stage activated LED will light and the first stage relay
contact will operate.
Double Zone Fire Condition
Upon receipt of a second fire condition when the control panel is switched to Automatic and Manual mode, the Abort
input is not active, and the Disable Extinguishant Sub-system function has not been invoked, the control equipment
will respond as above and as listed below:
• The second stage alarm output will operate. (NAC circuit S3)
•
The 2nd stage contact will operate.
• The release imminent indicator will operate
• The seven segment LED displays will indicate the time remaining until release in seconds.
