18 Channel 1 alarm is
latched
YES/NO   NO: When alarm condition is reached, the
device activates the alarm relay . When the
alarm condition is removed the alarm relay is
deactivated .
YES: When alarm condition is reached, the
device activates the alarm relay . When the
alarm condition is removed the alarm relay
remains set until the device is reset .
19 Channel 2 alarm is
latched
YES/NO
 
20 Alarm delay 0..240 s
 
When alarm condition is reached, a delay
period can be introduced before the alarm is
activated .
If the detector alarm condition is
removed before activation, the
delay is reset .
21 Auxiliary relay is used
for channel 2 faults
YES/NO
 
NO: Device faults are reported on the fault
relay; this relay is common on 2 channel
units .
YES, the AUX relay will separately report
CH2 faults; CH1 faults continue to be
reported on the fault relay . Common faults
will be reported by both relays .
Faults common to both channel
are, for example, ASD EEPROM
fault, external input fault, etc .
22 Channel 1 label 16 character (ASCII
code from decimal
32 to 127)
 
Provides a label to name a channel in free
text .
Example: "Building A" "Building
B"
23 Channel 2 label 16 character (ASCII
code from decimal
32 to 127)
 
24 Channel 1 fan speed
mode
Manual, Auto   Selects the fan speed control mode The optimal flow though the
device is about 45 litres/minute.
Typically, this is equivalent to
fan speed 5 .
Low and high flow limits are set
to meet the EN54 requirements.
A flow fault is given if the flow
goes out of the -20% and +20%
of the reference flow range.
In Auto mode, following
initialization, the unit sets the
fan speed to reach the reference
flow programmed in the device.
In Manual mode, the user can
set the fan speed.
Use PipeIQ LT to change default
configuration of the reference
flow (both modes) and fan
speed (manual mode).
25 Channel 2 fan speed
mode
Manual, Auto
 
26 Channel 1 manual fan
speed
1..10
 
Defines the fan speed in manual mode .
27 Channel 2 manual fan
speed
1..10  
28 Reference flow for
channel 1
32 – 65 litres/min
 
This value represents the correct flow level
to maintain .
29 Reference flow for
channel 2
32 – 65 litres/min
 
30 High flow threshold for
channel 1
Internal Setting
 
High flow threshold
31 High flow threshold for
channel 2
Internal Setting  
32 Low flow threshold for
channel 1
Internal Setting
 
Low flow threshold
33 Low flow threshold for
channel 2
Internal Setting
 
34 Flow fault delay 0..240 s
 
A delay can be set to stop reporting a flow
fault for a defined period .
If the fault condition is removed
before activation of a fault, the
delay will be reset .
35 Channel 1 filter due date DD/MM/YY
 
Date to clean air filters . When date is
reached, the device will give a filter fault .
36 Channel 2 filter due date DD/MM/YY
 
37 General fault is latched YES/NO
 
NO: The general fault relay is activated
when a fault is present and will reset when
the fault is removed .
YES: The general fault relay is activated
when a fault is present . When the fault
condition is removed the relay remains set
until a device reset .
38 General fault delay 0..240 s   A delay can be set to stop reporting a
general fault for a defined period .
If the fault condition is removed before
activation of a fault, the delay will be reset .
39 Pressure 68758 – 110000 Pa   Not used .
40 Power restart alert time 0 (Not Used), 1..240
s,
255 (no time limit)
 
When the device is switched on, it can give
a power on alert . The time period for this
alert signal can be set by the user .
