Introduction; Intended Use; Display And Led Light Ring - Setra Systems Lite Installation & Operating Manual

1.0 Introduction

The Setra Lite provides a simple, cost-effective, and accurate way to measure and display
room differential pressure in areas today that require manual verification. For local staff
managing area, Setra Lite has a light ring that is 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 fits in
a single-gang US electrical box, international 86-box or international round back-box, and
is powered by 24VAC or 24VDC. 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 visually 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 design provide an
intuitive visual indicator 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 and LED light ring that will glow red if room pressurization violates the
configured alarm threshold. The design of the light ring allows the room status to be visible
from a distance, even from down a hallway. With a simple press of the front lens of the unit,
the LCD displays the current differential pressure. Configuration 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.
