Introduction
This manual will assist you in the installation of the FAILSAFE Module (SKU
SS-PCB-GEN2) into existing handheld or panel mount Nuvair Pro Alarm analyzer
powered externally. This manual will also help customers understand the
function of Nuvair Pro Alarm analyzers equipped with a factory-installed
FAILSAFE Module.
The Nuvair Pro Alarm analyzer series are gas analyzers with alarms (visual
and/or audible) that activate when user-defined set points (low and/or high)
are violated.
Be sure to read the entire manual.

Module Description
As originally designed, most Nuvair Pro Alarm analyzers are:
- Manually controlled by an On/Off button on the front of the analyzer control panel.
- Equipped with a relay that can activate or disable external devices.
Some customers with a compressor-integrated analyzer want the compressor to shut down automatically if analyzer power is interrupted or the analyzer goes into alarm. In response to customer requests, Nuvair developed the FAILSAFE Module. Adding the FAILSAFE printed circuit board (PCB) to your existing Pro Alarm analyzer will automatically disable compressor power if:
- Analyzer power is interrupted, or
- Analyzer goes into alarm.
The FAILSAFE Module can be installed on the following on Nuvair Pro Alarm analyzers originally equipped with these power configurations:
- Wall plug-in
- DIN power
The FAILSAFE Module is not compatible with any battery-powered Pro Alarm
analyzer.
By installing the FAILSAFE Module, the analyzer will automatically power on
when compressor power is turned on.
The FAILSAFE Module can be purchased separately by existing Pro Alarm analyzer
owners, or the analyzer can be returned by the customer to the Nuvair
production facility in California (USA) for installation.
WARNING
This manual describes how a customer can install the FAILSAFE Module to
existing Pro Alarm handheld or panel mount analyzers. To complete this
installation, the customer must have a rudimentary knowledge of, access to,
and the ability to use and understand:
- Electronic components
- Small Phillips screwdriver
- Solder, and
- Soldering iron.
DANGER
Failure to properly install the FAILSAFE Module will result in the Pro Alarm
analyzer not functioning properly. An improperly operating analyzer will not
alarm and will not alert users that dangerous gas conditions exist. Exposure
to dangerous gases will result in significant injury or death.
