1 Introduction
The VPR-SD1 is an aspirating smoke detection system that utilizes an air-sampling pipe network to draw air
towards analog addressable point detectors installed inside a sealed enclosure.
The single channel VPR-SD1 detector enclosure (Figure1-1) has one pipe inlet and provision for one or two point
detectors allowing for redundant or double-knock detection. The range of supported point detectors is detailed in
Section 2.3.1 on page 10.
Point detectors are wired directly into the Signaling Line Circuit (SLC), which provides connectivity to the fire alarm
control panel for the reporting of alarms or faults originating from a point detector.
The detector enclosure provides a configurable aspiration system and airflow monitoring. Airflow status is displayed
on a ten element bar graph with adjustments for flow sensitivity and high/low flow thresholds. Flow faults are
indicated on the display interface LEDs, and reported to the fire panel via isolated dry relay contacts.
Note: The VPR-SD1 system has been tested and listed to UL 268 and UL 268A and must be installed in strict
compliance with these instructions to maintain the UL listing.

2.1 Mounting the Detector Enclosure
Notes:
l This equipment must be installed by a qualified installer in accordance with all local and national code
requirements.
l The detector assembly must be installed at an accessible position to facilitate maintenance and testing.
l Ensure that there is sufficient clearance to mount the detector, noting the location of air sampling pipes and
cable entry points. Owing to the rigid nature of the plastic pipe, installation must provide for sufficient movement
in all pipe work (air inlet, air exhaust and cable pipes) to allow pipe ends to be easily fitted and removed.
l Ensure that the exhaust pipe is free from any obstacles at all times.
l Do not mount the detector assembly close to a heat source.
l Mount the detector assembly in a secure location which is accessible only by authorised personnel.
Warning: Prior to drilling the attachment holes for the mounting bracket, ensure that all mounting surfaces (i.e.
walls, cabinet sides, etc.). are clear of electrical wiring and plumbing.
Mounting Procedure:
1. Remove the transparent cover (E) by using the corner stud key (B)to unscrew the tamper-proof corner studs
(A).
2. Tape the mounting template to the mounting surface and use it to accurately mark the holes corresponding to
the four corner fixing points.
3. Drill four holes in the mounting surface.
4. Remove the mounting template.
5. Secure the unit to the mounting surface through the four corner fixing points. Use appropriate fasteners for the
type of surface that the unit is mounted on. The diameter of each mounting hole is 0.19 in. (5 mm). Typical No. 8

3 Pipe Network Installation
This section provides a simple guide to pipe installation and should contain all the information required for simple
installations based on the standard configurations shown in Section 3.9 on page 17.
Use appropriate CPVC pipe with sampling point holes drilled along its length. The pipe run is terminated with an end
cap that may have a sampling hole drilled in its center.
The position of each individual sampling point should be in accordance with the rules for the positioning of point
detectors. It is important to note that the concentration of smoke on an individual sample point will be diluted by the
clean air from the other sampling points.
3.1 Pipe Specification
CVPC Pipes
For compliance, the pipe should have a nominal outer diameter (OD) of 1.05 in. (26.7 mm). The sample pipe is
normally supplied in boxes of 15 ft (4.57 m) lengths and is cut as required and joined by solvent welded sockets
(permanent), or socket unions (removable). Refer to Table 1-1 on page 1 for ordering information.
The pipe shall be orange and be marked with descriptions such as "CAUTION- Smoke detector sampling tube - Do
not disturb" as required by NFPA 72.
Note: The VPR-SD1 inlet port is tapered to allow a push fit of the sampling pipe. The pipe should be cut squarely to
ensure a good, airtight seal. Solvent adhesive should not be used for this joint. Using adhesive on the inlet
and outlet port connections will void the warranty of the detector enclosure.
Use pipe cutting shears or a wheel type plastic tube cutter to cut pipes to the required length as per the sampling
network design. Ensure that cuts are square.
Flexible Tubes
Flexible tubes may be used in duct applications or in places where conventional pipes cannot be easily installed. It is
recommended that 3/4" (19mm)OD, 1/2" (12.7mm) ID Polyethylene flexible piping is used with an adapter to enable
connection into the inlet port of the detector enclosure. Flexible tubing is available in 50 ft (15 m) and 25 ft (7.5m)
coils. Refer to Section 3.10.1 on page 23 for ordering information.
3.2 Fixings
The normal fixing methods are pipe clips, saddle clamps or even tie wraps. Fixing centers are typically 5 ft (1.5 m)
apart.

3.3 Sampling Holes
Sampling holes can either be pre-drilled or drilled in situ. Use a low speed drill with a sharp drill bit to prevent debris
from entering the pipe. Always blow compressed air through the pipe after drilling to clear any debris before final
connection to the equipment.
Sampling Holes for Open Area Applications
l The installer can drill the necessary holes in sampling probes and exhaust pipes either prior to or during
installation, as per the sampling pipe network design.
l In standard configuration, with pipe hanging from ceiling, holes should be placed underneath, so the smoke can
easily rise up into the hole.
l It is important that the correct diameter sampling holes be drilled, as this affects system performance and
efficiency.
l Sampling holes must be drilled at 90 degree angles to the pipe.
l Attach adhesive labels to identify the sampling points.
Sampling Holes for Duct Applications
l The installer can drill the necessary holes in sampling probes and exhaust pipes either prior to or during
installation, as per the sampling pipe network design.
l Sampling holes must be oriented facing away from the airflow.
l Sampling probes and exhaust tubes must be matched with the same number of holes, each with the same
diameter.
3.4 End Cap
Legend
A End Cap
B Sampling Hole
Figure3-1: End cap with hole drilled in center
End Cap for Open Area Applications
l The end of the pipe must be capped with an end cap and not be left open.
l The end cap typically has a sampling hole drilled in its center to control airflow. For pipes with only a few
sampling holes, it is recommended that the end cap hole be same size as the sampling holes along the pipe. The
hole in the endcap is included in the total number of holes.
Refer to Section 3.9 on page 17 for approved configurations.
End Cap for Duct Applications
l End caps without sample holes are required for both sample and exhaust tubes.

3.5 Bends
90 degree elbows may be used for making turns in the 3/4" CPVC sample pipe network. The total number of 90
degree elbows in a single pipe run must be kept to 10 or less to maintain acceptable system performance.
Figure3-2: 90° elbow bend
3.6 Capillary Tubes
For above ceiling or concealed open area applications, capillary tube air sampling can be used.
Note: The maximum allowable length for a capillary tube is 10 feet.

G Label
Figure3-3: Capillary Tube
3.7 Exhaust
Where the VPR-SD1 is located outside the protected area, consideration must be given to returning the exhaust air
to the protected environment to balance pressure differences that may exist between the two areas. In the majority
of applications, this is not necessary as pressure differences are minimal.
Examples of where the exhaust should be returned to the protected area include:
l where pressure differences exceed 50 Pa from where the detector is located outside the protected area.
l where there are hazardous substances inside the protected area, for example hospital operating theatres,
laboratories.
Pipe of the same specification as the sampling pipe runs should be used and its length limited to a maximum of 30ft
(10m) to avoid significant reduction in the airflow. Care should be taken to position the new exhaust outlet where it
cannot be accidentally or deliberately blocked.
Return air pipes need to be as short as possible to minimize the effect of airflow resistance in the return air pipe
network.

3.9.1 Open Area Sampling Pipe Network Design
The VPR-SD1 supports a number of pre-engineered pipe network designs.These designs incorporate suction
pressure and transport time considerations.
Caution: The performance of this system is dependent upon the pipe network. Any extensions or modifications
to the designed installation may cause improper operation. The operational effects of such changes
shall be verified. Any changes must be carried out in accordance with the pre-engineered pipe
networks defined in this document.
The pre-engineered designs assume the following constraints:
1. All sampling points are open holes.
2. For branched designs, the pipes should be balanced, be of equal length and have an equal number of sampling
holes along each branch.
The pre-engineered pipe network designs provide:
l Transport Times: <120 Seconds
l Suction Pressure: Greater than or equal to 115 Pa
l Sampling Point Sensitivity: <=3 %/ft (10 %/M)
The information below shows the parameters for pre-engineered designs.

3.10.2 Duct Pipe Network Installation
Rules
1. While not mandatory, it is recommended that when possible locate probes a minimum of six duct widths
downstream from bends or inlets. Such locations ensure that air flow is non-turbulent and that smoke is properly
mixed with air in the duct for maximum detector/sensor efficiency.
Note: Installation of a duct detector/sensor to a round duct is the same as shown in Figure3-11 and
Figure3-12.
2. Position the probes so that dampers do not restrict air flow at the probe location (Figure3-10).
Figure3-10: Probe Placement - Location of Dampers
Figure3-11: Probe Placement - Bend or Inlet Locations
Figure3-12: Probe Placement - Air Return Inlet Locations
3. Position the probes on the return or supply duct of the equipment’s air handling system. However, probes should
NOT be installed in the return air damper branch (Figure3-10).
4. Position the probes on branch lines if close identification of the alarm source is required.
5. Position the probes on the downstream side of filters to sense fire in filters. However, should the filters block,
sufficient air flow may not be available for proper detector/sensor operation (Figure3-10).
6. Whenever possible, position the probes where they can be conveniently observed.
7. Position the probes in return air ducts ahead of mixing areas.
8. Do not position the probes next to outside air inlets unless you want to monitor smoke entry to the handling
system from an adjacent area.
9. Position the probes upstream of air humidifiers and cooling coils.

Notes:
l The sample and exhaust tubes should be installed in a location of relatively non-turbulent air flow and within the
intended opening velocity range of 0-4000 feet per minute (0 to 1220 m/minute). It is recommended that
measurements of airflow and examination of engineering specifications that define expected duct air velocities
under all conditions and that measured velocities do not exceed the airspeed rating of the detector to be used.
This is done to determine if a location is suitable for duct sampling operation. An Alnor Instrument Co. (Chicago)
Model 6000P Velometer or equivalent (not supplied) may be used to check the duct air velocity.
l The sampling and exhaust holes must be oriented facing out of the airflow. Refer to Section 3.3 on page 14 for
further information.
l There must be at least 1 hole for every 1 foot of the inlet probe.
l The inlet probe and outlet probe must have equal number of same diameter of holes in order to have a balanced
airflow in the pipe network.
l Do not drill holes in the flexible tubes.
3.10.3 Duct Inlet Probe and Exhaust Pipe Installation
1. Mark the location of the mounting plates.
2. Drill or cut-out 2.0" in - 2.2" (50 mm - 55 mm) holes in the duct wall.
3. Cut the flexible tubes to the correct length. If longer than 3 feet, ensure the opposite end is supported on the duct
wall. This will maintain sample probe integrity across all duct air velocities.
4. Install the duct mounting plate - insuring that the plate covers the hole cut in duct in step 2 above.
5. Install the end caps to the inlet sampling probe and exhaust pipe.
6. Insert the sample probe through the compression fitting in the duct probe mounting plate.
7. Loosen the pipe compression adaptor coupling and insert the end of the sample tube. Tighten the compression
nut until the elbow is secure to the sample tube.
8. Repeat steps 2 thru 6 for the exhaust probe.
9. Insert the flexible tube to the elbow connector for the inlet and exhaust tubes. Tighten until the tube is secure.

3.10.5 Flexible Tube / CPVC Pipe Installation
1. Check the pipe network design documents of the given application to gather the size, configuration and
mounting specification of the pipes.
2. Measure and mark the spots specified for the pipe mounting clips.
3. Secure the mounting clips to the specified locations.
4. Temporarily join the flexible tubes/CPVC pipes and secure them on the mounting clips.
5. Insert the inlet and exhaust pipe to the VPR-SD1.
6. Test the operation of the system.
7. After successful completion of the test, tighten all the flexible tube connectors until secure. If CPVC pipes are
used, bond the pipes together using suitable adhesive. Do not use adhesive on the VPR-SD1 inlet and outlet
port connections.

4.3 Parameters
The Fan Speed, Flow Limits and Flow Sensitivity need to be set for each installation prior to Flow Calibration and
testing. It is not possible to provide the settings for all possible installations but the following guidelines should
assist in the commissioning of the unit.
4.3.1 Fan Speed
The Fan Speed should be set as high as possible to achieve the fastest transport time from the sampling point to the
detectors, this is especially important for longer pipe lengths and for installations that must conform to the
requirements of NFPA 72 - a transport time of 120 seconds (max). There is, however, a balance to be achieved
between performance and the power requirements for the system and reference should be made to the current
consumption figures in the specifications prior to setting this value.
4.3.2 Flow Delays
By default, an increase or decrease in flow beyond the FLOW HIGH and FLOW LO limits will result in a FLOW
FAULT after a delay of approximately 30 seconds. Once the flow is returned to a normal level, the fault condition will
be cleared within 18 seconds.
In environments where the sampled airflow may be affected by sudden temperature or pressure changes, or if there
is a risk of physical interference of the sampling point (e.g. prison cell applications) then it may be necessary to
increase the delay between when flow limit has been exceeded and instigating a FLOW FAULT condition.

4.3.3 Flow Sensitivity
This setting determines the system's responsiveness in reporting blocked sampling points or broken pipes. The
number of sampling points and fan speed are the main factors to consider for this setting.
The following table shows typical settings for a variety of standard fan speed and hole quantity combinations. Other
speed and hole combinations should be verified by testing during commissioning.

Sampling
Method
Open Area 1 - 2 sample holes per pipe 6 - 9 5
Duct 2 - 3 sample holes 6 - 9 5
Duct 4 - 5 sample holes 6 - 9 7
Duct 5 or more sample holes 6 - 9 9
Notes:
1. Fan speeds must be adjusted to suit specific pipe networks to transport requirements (max 120 seconds).
2. Duct Applications must have inlet and exhaust probes matched for number of holes.

5 Testing
Note: Testing should only be carried out by qualified personnel. To prevent unwanted alarms, ensure that the proper
authorities have been informed and that the unit has been isolated from the fire alarm system.
Note: In cases where the control panel provides an alarm test facility, this may be used in place of the following
alarm tests.
5.1 Point Detectors
Open Area Application Testing
l With the unit powered up and top cover removed the detectors can be tested for alarm functionality using
methods described by the manufacturer (for example, aerosol spray).
l An airflow test may also be performed at this time as the detector should report a low flow fault with the top
cover removed.
Duct Application Testing
1. Unplug the test port plug (A).
2. Spray 3 to 5 second bursts of smoke from the aerosol smoke tester.
3. The point detector must go into alarm within 10 seconds. If the detector fails to go into alarm, perform
troubleshooting. Refer to Chapter 7 for further information.
4. Insert the rubber plug back into the test port hole to avoid an airflow fault.
5.2 System
The installed system must be checked with the top cover securely fitted.
For open area applications, smoke should be introduced to the furthest sampling point from the VPR-SD1 system on
each branch of the pipe.
The choice of smoke source is dependant on the installation but in all cases the smoke must be present for the
duration of the test - some aerosol sprays for point detectors may not work on aspirated systems. Manufacturers
recommended test method(s) for the specific detector mounted in the VPR-SD1 should be followed.
If it is possible to get close to the sampling point then a basic "Go / No-Go" functional test can be carried out with
smoke matches or lighted paper etc.
Ensure that the system complies with manufacturer's instructions and all local and national code requirements.

6 Maintenance
Maintenance should only be carried out by qualified personnel. To prevent unwanted alarms, ensure that the proper
authorities have been informed and that the unit has been isolated from the fire system.
Caution: When installing or servicing the unit, ensure that the operator is safely grounded so as to prevent
electro-static discharge (ESD) damage to the unit.
Notes:
l Prior to carrying out any work or maintenance on the VPR-SD1, take the necessary steps to advise the
monitoring authority that power may be removed and the system disabled.
l Point detectors should be serviced in accordance with the manufacturer's recommendations.
l The system must be tested in accordance with inspection, test and maintenance specifications as stated in
NFPA 72.
6.1 Air Inlet Filter Replacement Procedure
With normal use, the filter element will eventually become contaminated with dust particles, impeding airflow, and it
is recommended that the filter element (order code VPR-SDFILTER) is changed every six months or as necessary.
The frequency of filter replacement depends on environmental conditions. For example, where the detector is placed
in extreme environmental conditions, the filter should be changed every three months.
1. Remove the transparent cover using the special tool provided to unscrew the tamper proof fasteners.
2. Lift out the foam filter element from the filter tube using tweezers or long nosed pliers.
3. Fit a new filter element. Ensure that the filter is not compressed during fitting and that it is positioned flush with
the top of the filter tube.
4. Replace the transparent cover.
