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 (Figure1-1) 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.
Figure1-1: VPR-SD1 Detector Enclosure
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:
lThis equipment must be installed by a qualified installer in accordance with all local and national code
requirements.
lThe detector assembly must be installed at an accessible position to facilitate maintenance and testing.
lEnsure 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.
lEnsure that the exhaust pipe is free from any obstacles at all times.
lDo not mount the detector assembly close to a heat source.
lMount 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.

FireNET Vapor VPR-SD1 Product Guide Hochiki America Corporation
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
lThe 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.
lIn standard configuration, with pipe hanging from ceiling, holes should be placed underneath, so the smoke can
easily rise up into the hole.
lIt is important that the correct diameter sampling holes be drilled, as this affects system performance and
efficiency.
lSampling holes must be drilled at 90 degree angles to the pipe.
lAttach adhesive labels to identify the sampling points.
Sampling Holes for Duct Applications
lThe 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.
lSampling holes must be oriented facing away from the airflow.
lSampling probes and exhaust tubes must be matched with the same number of holes, each with the same
diameter.
3.4 End Cap

Legend
AEnd Cap
BSampling Hole
Figure3-1: End cap with hole drilled in center
End Cap for Open Area Applications
lThe end of the pipe must be capped with an end cap and not be left open.
lThe 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
lEnd caps without sample holes are required for both sample and exhaust tubes.
