2 Product Information
2.1 How it Works
The VESDA VLQ detector continually samples air from the protected environment via two pipe inlets for the
sampling pipes on each side of the pipe inlets (A1, A2). Upon entering the detector, the air passes through
respective inlet manifolds (B1, B2) and the aspirators (C1, C2). The sampled air then enters the filter (D)
where the majority is exhausted out through filter exhaust (I2) and a portion from each inlet is separated into
two pathways, one pathway enters as clean air (E1,E2) and the other pathway enters as sampled air (F1,F2)
into the detection chamber (G). Sampled air is used for smoke detection and the clean air used for optics
protection. After smoke detection the air is exhausted out of the chamber exhaust (I1). Flow measurement is
performed at the chamber exhaust (H).

2.2 Detector Overview
The VESDA VLQdetector is a lightweight unit designed to be ceiling or wall mounted and operates with a
simple sampling pipe network. The detector unit features two sampling pipe inlets, unobtrusive exhaust vents,
a simple control panel and display, and a buzzer to provide audio notifications.
AUSBport, described below in Section 2.2.3, provides the ability to interface with a computer, which allows
configuration with the Xtralis QSC software. Configuration DIPswitches and wiring terminals are located
beneath the detector and are accessible by removing the detector base..

Indicators
The VESDA VLQ detector provides information via a series of Status LEDs.
LED Color Description
A Power Green The Power LED illuminates when the detector is
powered up.
B Filter Replacement Yellow The Filter Replacement LEDis lit when the filter is due
for replacement.
C Fault Yellow The Fault LED is lit when a fault condition is detected.
D Pre-Alarm Red The Pre-Alarm LED is lit when the Pre-Alarm threshold
is reached.
E Fire-Alarm Red The Fire LED is lit when the Fire threshold is reached.

Buttons
The VESDA VLQ detector provides accessibility to a range of functions via a set of control buttons.
Button Description
Reset / Silence Resetting the detector unlatches all latched alarms and
faults, returns relays to their normal state and clears the
active event list.
Silencing silences the buzzer for the current fault.
l To reset the detector, press this button once, 'rs' is
displayed on the panel.
l To silence the buzzer, press and hold this button till
"SI" is displayed on the panel (5 to 10 seconds). SI is
displayed alternately with the highest priority fault
code. The buzzer will remain silent unless another fault
is reported.
l To take detector out of Silence mode, press this button
once while detector is displaying "SI".
While the filter is removed, pressing the Reset / Silence
button once will reset the filter use percentage value.
Disable / Standby Disabling the detector disables all relay outputs with the
exception of the fault relay. The aspirator remains active.
Standby shuts down the aspirator and puts the detector
standby mode. There is no smoke detection during standby,
and the fault relay is activated.
l To disable the detector, press this button once.
l To re-enable the unit, press the button while "db" is
displayed on the panel.
l To place the detector in standby mode, press and hold
this button until "Sb" is displayed on the panel (5 to 10
seconds). To take detector out of standby mode, push
and hold this button when "Sb" is displayed on the
panel (5 to 10 seconds).
Note: You must be logged on to the detector through
front panel to use this button. Refer to Section 5.1
for further information.
Test Two Test modes are available:
l Lamp and Buzzer Test: Press this button to ensure
that all LEDs,display segments and buzzer operate
correctly. "Lt" is displayed momentarily when the
button is pressed.
l Alarm and Fault Test:Press and hold this button until
"At" is displayed on the front panel (5 to 10 seconds). It
activates alarm and fault relays. To stop the test press
and hold this button when "At" is displayed on the
panel.
Note: You must be logged on to the detector through
front panel to use this button. Refer to Section 5.1
for further information.

Button Description
Normalize Airflow /
AutoLearn Smoke
Airflow Normalization sets the reference point for airflow
thresholds based on ambient operating conditions.
AutoLearn Smoke sets the alarm thresholds based on the
environmental conditions.
l Press this button once to start the flow normalization,
'no' is displayed on the panel. Normalization takes
between 5 to 10 minutes. To cancel normalization
press this button while 'no' is displayed.
l To start the AutoLearn smoke press and hold this
button till "AL" is displayed on the panel. AutoLearn
takes 15 minutes to complete when started from the
panel. To cancel the AutoLearn press and hold this
button when "AL" is displayed.
Notes:
l AutoLearn Smoke thresholds are volatile, therefore if
thresholds are set using AutoLearn smoke then it must
be run each time the detector is powered up.
l AutoLearn Smoke over-rides the DIPswitch settings
within the smoke threshold range. Refer to Section 5.3
for further information.
l You must be logged on to the detector through the front
panel to use this button. Refer to Section 5.1 for further
information.
Table2-2: Control Buttons (continued...)
2.2.2 Buzzer
The buzzer will sound under the following conditions:
l During power up self testing.
l When a Pre-Alarm is raised, the buzzer will alternate between on and off until the detector is silenced or
the smoke is no longer present.
l When a Fire alarm is raised, the buzzer will beep continuously until the detector is silenced or the smoke
is no longer present.
l When a Fault is detected, the buzzer will alternate between on and off until the detector is silenced or the
fault condition is corrected.
l During a manually initiated system test.
2.2.3 USB Port
Detector configuration can be performed using the Xtralis QSC software installed on a computer connected to
the detector via the USB port. The USB port is located on the outside of the detector, beneath the shroud. It is
necessary to remove the rubber grommet in order to access this port.
