5.5.2 SUPERVISORY OPERATION
If a VESDA is configured in the Cheetah control panel for
SUPERVISORY
, the following levels and states will
be seen and activated on the panel:
♦
Alert Level
= Pre-Alarm LED illuminates on panel, piezo sounds (constant), and Pre-Alarm 1 state
entered for the configured panel zone. None of the onboard relays change states. Condition is non-
latching and will clear itself when obscuration level drops below the
Alert
Level in the VESDA. (Unless
VESDA is set to latching on Alarms)
♦
Action Level
= Pre-Alarm LED illuminates, on panel, and Pre-Alarm 2 state entered for the configured
panel zone. None of the onboard relays change states. Since this is a new smoke level, Piezo will
resound if it was silenced in
Alert
Level. Condition is non-latching and will clear itself when obscuration
level drops below the
Action
Level in the VESDA. (Unless VESDA is set to latching on Alarms)
♦
Fire-1 Level
= Supervisory and Pre-Alarm LEDs illuminate on Panel, Piezo sounds and Supervisory
State activates for the configured panel zone, and on board Supervisory relay energizes. This state is
latching and panel will need to be reset after obscuration drops.
♦
Fire-2 Level
= Supervisory and Pre-Alarm leds illuminated on Panel, and Supervisory State activated for
the configured panel zone, and on board Supervisory relay remains energized. Since this is a new Alarm
Level, Piezo will resound if it was silenced in
Fire 1
Level This state is latching and panel will need to be
reset after obscuration drops.
L
Note:
Pre-Alarm conditions are non-latching in the control panel. However, if the VESDA is configured to
latch on alarm states, the VESDA will keep that level from clearing on the control panel. Since this
Supervisory State is caused by VESDA
Fire 1
or
Fire 2
, it is a latching event at the panel whether the
VESDA is configured to latch on alarm or not.
5.5.3 TROUBLE
OPERATION
If a VESDA is configured in the Cheetah control panel for
TROUBLE
, the following levels and states will be
seen and activated on the panel:
♦
Alert Level
= Pre-Alarm LED illuminates on panel, piezo sounds (constant), and Pre-Alarm 1 state
entered for the configured panel zone. None of the onboard relays change states. Condition is non-
latching and will clear itself when obscuration level drops below the
Alert
Level in the VESDA. (Unless
VESDA is set to latching on Alarms)
♦
Action Level
= Pre-Alarm LED illuminates, on panel, and Pre-Alarm 2 state entered for the configured
panel zone. None of the onboard relays change states. Since this is a new smoke level, Piezo will
resound if it was silenced in
Alert
Level. Condition is non-latching and will clear itself when obscuration
level drops below the
Action
Level in the VESDA. (Unless VESDA is set to latching on Alarms)
♦
Fire-1 Level
= Trouble condition on Panel, Trouble LED illuminates, Piezo sounds and on board Trouble
relay changes states. This state is latching and panel will need to be reset after obscuration drops.
♦
Fire-2 Level
= Trouble condition on Panel, and on board Trouble relay remains in the Trouble state.
Since this is a new Alarm Level, Piezo will resound and Trouble Led will re-illuminate if it was silenced in
Fire 1
Level. This state is latching and panel will need to be reset after obscuration drops.
L
Note:
Pre-Alarm conditions are non-latching in the control panel. However, if the VESDA is configured to
latch on alarm states, the VESDA will keep that level from clearing on the control panel. Since this Trouble
State is caused by VESDA
Fire 1
and/or
Fire 2
, it is a latching event at the panel whether the VESDA is
configured to latch on alarm or not.
