1.0 Introduction
The Setra Lite provides a simple, cost-effective, and accurate way to measure and display
room differential pressure in areas that previously require manual verication. For local staff
managing area, Setra Lite visual and audible alarms. The light ring displays green or red,
showing a clear indication of room conditions. For the facility manager, using the Lite means
the frequency of preventative maintenance walk-by inspections can be reduced because
Setra Lite is monitoring the space.
Setra Lite has many features found only in larger, more complex room pressure monitors.
These include a bright light ring that can be seen at an angle or down a hallway, a digital
display of the pressure value that is always-on or momentary, an alarm delay for door entry,
and POS or NEG room mode. The Setra Lite sensor has Setra’s accuracy and reliability that
you can trust.
Setra Lite is about the size of a standard light switch and just as simple to install. It ts in a
single-gang US electrical box, international 86-box or international round back-box, and is
powered by 24VAC or 24VDC. Additional mounting options are available for temporary spaces
or replacement of existing pressure monitors. The reference side pressure pickup is integral
with the Lite faceplate. An analog output provides the building management system with the
pressure signal for any additional trending or alarming needed.
The Setra Lite also integrates seamlessly with the Setra Flex environmental monitor. Mount
Setra Lite at additional doors that enter the space and use an on-screen badge to display its
value.
1.1 Intended use
Setra Lite is designed to sense and indicate the pressurization status of critical environments,
including cleanrooms and sensitive hospital areas (sterile bronchoscopy rooms, and other
USP 800 compliant pressurized spaces). Setra Lite is designed to provide an intuitive visual
and/or audible indication of the status of the room and can also be tied into other devices via
analog output.
1.2 Display and LED light ring
Setra Lite features an LED light ring that will glow red and/or audibly alarm if room pressurization
exceeds the congured alarm threshold. With a simple press of the front lens of the unit, the
LCD displays the current differential pressure and silences the audible alarm. Conguration of
the unit can be performed on the device via buttons located behind the removable front lens.
The unit can be put into and taken out of “Standby” mode by pressing the front lens 3 times
in quick succession.

3.0 Rough-in installation (Wall Mount)
For Setra Lite to be installed correctly, the rough-in phase of the project must be completed
properly. This section will outline the specic considerations the Installer must pay attention
to so that the nal wiring and commissioning will go smoothly.
3.1 Installer Provided Materials
The following is a list of parts required and supplied by installer for Setra Lite:
1. Power (18-22 AWG recommended) and signal wire
2. 1/8 in. ID silicon tubing to run from the room(s) Pressure Pickup Port(s) to the Setra Lite
monitor or external sensors. (Standard monitor only)
3. 24 VAC or VDC transformer, capacity rated for number of Setra Lite units powered
4. Single-gang electrical box, if opting not to install directly into wall

3.2 Prepare wall for mounting - Permanent installations
1. Cut a 2" hole in the wall for the Setra Lite base unit or install 1-gang electrical box
Note: Be sure to install electrical box in correct orientation based on purchased
conguration (Portrait or Horizontal)
2. Cut a 1" to 2" hole or install 1-gang electrical box for each Pressure Pickup Port (RPS),
either horizontal ceiling mounted or vertically mounted high on a wall surface
Standard: Install RPS either horizontal ceiling mounting or vertical mounted high on a
wall surface
Dual Alert: Cut a 2" hole in the wall. Install pressure pickup port on opposite side of the
wall from base unit in portrait or landscape orientation based on purchase conguration
3. Run all wiring to the Setra Lite electrical box
3.4 Considerations to avoid kinked or damaged tubing
Pull tubing runs in a manner that protects the tubing from being damaged, cut, or crimped. Any
break or bend in the tubing may affect the integrity of the pressure signal. DO NOT TIGHTEN
STRAIN RELIEFS at the electrical boxes so that they crimp the tubing. Leave the strain reliefs
open enough so that the tubing can slide in and out of the box with a few inches of play.
During tubing installation and prior to use, tape the open ends of the tubes closed to prevent
contamination during construction.
During nal installation of the Pressure Pickup Port, careful observation should be made of
how the tubing gets pushed back into the wall for nal faceplate mounting.
3.3 Plumbing
For the standard Lite
, a Pressure Pickup Port (RPS) is installed in the primary monitored room and Setra Lite is
installed in the reference area (typically a hallway). For the Inside Room Lite ("IR" on the
startup screen under the Setra logo), the Pressure Pickup Port (RPS) should be installed in the
reference area and the Setra Lite is installed inside the primary monitored room. 1/8” ID soft
platinum-cured silicon tubing is typically used to bring the pressure signal from the Pressure
Pickup Port to the pressure tting on the back of Setra Lite.
Note: Caution should be taken to locate the Pressure Pickup Port and Setra Lite at least
six (6) feet from air turbulence that may originate from air supply diffusers, slot diffusers,
mobile equipment cooling fans, or other devices that may exhaust air in the direction
of the ports. Air velocity blowing directly on these ports can cause inaccurate pressure
measurement.

4.0 Installing Lite base unit (Permanent installations)
1. Connect pressure tubing from the
Pressure Pickup Port to the port on the
back of Setra Lite.
2. Connect wiring for power and analog
output (if required) per section 7.0
Dual Alert: This variant will have an
additional wire lead connected to the
back of the unit.
Thread the wire lead through the wall and
into the pressure pickup port box or hole
on the opposite side of the wall.
3. As you push the Setra Lite unit into the
electrical box, push the tubing into the
conduit tube or into the wall cavity.
4. Push Setra Lite into the enclosure and
secure with two (2) mounting screws.
Note: Setra Lite should be installed, powered and operational for 30 minutes for warmup
and acclimation for one-time pressure sensing stabilization. If necessary, after the warmup,
units can be re-zeroed. Setra Lite contains a small air valve to allow for one-touch zeroing
via the conguration menu.
5. When the home screen appears, Setra Lite
can be congured via 3 buttons located
below the LCD display on the circuit
board. See section 8.0 for conguration
instructions and details.

6. Prior to installing the faceplate, be sure
the rubber seal is properly installed on the
back of the faceplate.
7. Install the faceplate by rmly pressing it
into place over the base unit housing.
Note: Press the plate in at a slight angle,
leading with the bottom edge.
8. After conguration is completed align and
engage the top two snaps. Then, align
and install the front lens to the faceplate
by inserting top snap rst, followed by
the bottom snap. Left and right snaps are
alignment only.

2. Secure the mounting plate with provided
mounting hardware based on installation
type (Direct wall or electrical box)
5.1 Standard Monitor and Quick Mount Pressure Pick Up Port Install
Note: The base unit should be fully installed. Tubing and wire lead from back of base unit
should be threaded into the box or hole prepared for the dual alert pressure pickup.
5.0 Pressure Port Installation
1. Install the supplied silicone tube (with integrated external spring) and attached barbed
tube adapter on the rear face of the RPS unit onto the end of the 0.25” eld tubing. This
short length of tubing is used as a safety to prevent any kinking inside tight spaces. Add
your typical run of 1/8”ID x1/4"OD tubing between the pressure pickup and the Setra Lite.
2. Screw RPS into electrical box or wall.
During nal installation of the Pressure Pickup Port, careful observation should be made of
how the tubing gets pushed back into the wall for nal faceplate mounting.
5.2 Dual Alert Pressure Pick Up Port Install
1. Thread the tubing and wire lead through
the mounting plate.
