LPT - Operation Manual
Rev. E | 2021.03
A bump test will help you determine if a sensor requires calibration. If the sensor still does not
respond as it should after a successful calibration, it probably requires replacing.
6.2 General Safety Warnings
The LPT is intended for indoor use, permanently mounted at a height that is appropriate for the
type of gas being monitored. See Section
6.5 Sensor Mounting Heights
. The LPT should be protected
from extreme weather conditions.
The LPT requires no assembly and virtually no maintenance other than regular calibration of the
integral and/or remote sensors and ensuring that excess water or dust is not somehow entering
the enclosure and physically damaging the circuit board or internal components. There are no
serviceable elements other than the calibration instructions outlined in this manual. There are no
replaceable components except the sensors.
6.3 Protection Against Electrical Risks
Disconnect all power before servicing. There may be multiple power sources. Power supply must
have a building installed circuit breaker / switch that is suitably located and easy to access when
servicing is required and should be labelled as LPT supply (disconnecting power to the LPT).
Appropriate markings should be visible at the circuit breaker / switch that is supplying power to
the LPT.
This device may interfer with pacemakers. Modern pacemakers have built-in features to protect
them from most types of interference produced by other electrical devices you might encounter in
your daily routine. If you a have a pacemaker, follow your healthcare provider’s instructions about
being around this type of equipment.
