Description

The LPT-B is a full featured, 3 channel, BACnet® transmitter for use in non-hazardous, non-explosion rated, commercial and light industrial applications. It is available with a wide range of internal and/or external sensors and sensor types including electrochemical, catalytic and PID TVOCs.

The LPT-B may be configured to operate as a standalone fixed system or be part of a digital network. It offers a BACnet® MS/TP output signal for communicating with a Controller or Building Automation System, an audible internal alarm, one SPDT dry contact relay, LCD display with user selectable functions, temperature compensation and thermal resetting fuses all in a RoHS compliant package.

The LPT-B comes in a standard water / dust tight, corrosion resistant ABS / polycarbonate enclosure with a hinged, secured door. It is IP54 rated with the optional splash guard installed which provides protection in water spray or wash down applications.

The LPT-B is not compatible with CETCI’s Controllers. It is intended to be used alone or integrated into an existing BACnet® network.
