Point Database  
Chapter 3 presents a description of the Fume Hood Controller point database including point 
descriptors, point addresses, and a listing of applications in which each point is found. 
Address Descriptor 
Description 
01 
CTLR ADDRESS 
Identifies the controller on the FLN trunk. Valid values: 0 through 98. 
02 
APPLICATION 
The identification number of the Application running in the controller. 
05 
LOW ALM 
This point displays an ON or OFF status. When the exhaust flow goes below the 
value specified at LOW ALM LMT for the time specified in ALARM TIME, the 
point goes into an alarm state (ON); the red LED is illuminated, the alarm 
sounds, and the message “FLOW LOW” displays at the ODP. 
06 
HIGH ALM 
This point displays an ON or OFF status. When the exhaust flow goes above the 
value specified at HI ALM LMT for the item specified in ALARM TIME, the point 
goes into an alarm state (ON); the red LED is illuminated, the alarm sounds, and 
the message “FLOW HI“ displays at the ODP. 
07 
EMER ALM 
This point displays an ON or OFF status that indicates if the EMERGENCY 
PURGE button on the ODP has been pressed. When the operator presses the 
EMERGENCY PURGE button, the point is ON, the red LED is illuminated, the 
alarm sounds, and EEE and EMERGENCY MODE display at the ODP. If pressed 
again, then the point is OFF. This point can be commanded by a field panel. 
08 
GEN FAILURE 
Indicates a hardware failure (e.g., the pressure sensor) with an ON or OFF 
status. The red LED is illuminated; the alarm sounds, and FFF and GENERAL 
FAILURE
 display at the ODP. 
10 
HI ALM LMT 
The value above FLOW STPT, in percent, at which the red LED and audible 
alarm are activated on the ODP. This point is the setpoint for HIGH ALM. Valid 
values: 100 through 255%. 
11 
HI WARN LMT 
The value above FLOW STPT, in percent, at which the yellow LED is illuminated 
on the ODP. Valid values: 100 through 255%. 
12 
LOW WARN LMT 
The value below FLOW STPT, in percent, at which the yellow LED is illuminated 
on the ODP. Valid values: 0 through 100%. 
13 
LOW ALM LMT 
The value below FLOW STPT, in percent, at which the red LED and audible 
alarm are activated on the ODP. This point is the setpoint for LOW  ALM. Valid 
values: 0 through 100%. 
14 
EMER TIMER 
When EMER ALM is set to ON, the time set for EMER TIMER is used as the 
length of time the EXH FLOW is commanded to full flow (the exhaust flow control 
device is full open). After the time in EMER TIMER times out, the EXH FLOW is 
controlled to the value set in EMER STPT. Valid values: 0 through 32, 767 
seconds.
