Key Features
  • 1, 2 or 3 channel operation with internal and/or remote sensor configurations
  • Modbus® RS-485 RTU communication
  • LCD display
  • 24 VDC power
  • 4-conductor daisy chain network wiring
  • Standard water / dust tight, corrosion resistant enclosure (drip proof)
  • IP54 rated with optional splash guard installed.

The LPT-P is an economical, three channel, digital transmitter that is designed to be part of a gas detection system 
for enclosed parking facilites/parkades and vehicle repair shop applications. It can be configured with a single and/or
dual internal electrochemical Carbon monoxide (CO) and/or Nitrogen dioxide (NO2) sensor and/or one catalytic
combustible ESH-A Remote Sensor.
The LCD display provides at-a-glance gas readings for each channel along with alarm and communication status. 
Navigating the menu can be done unobtrusively with a magnetic wand or by using the internal programming buttons.
The LPT-P is not a standalone gas detection device, it operates on a local area network (LAN) using Modbus® 
RS-485 RTU serial communications with a Controller, a control panel, Direct Digital Control system (DDC) or a Building
Automation System (BAS). The LPT-P does not have an internal alarm or relay.
The LPT-P comes in a standard water / dust tight, corrosion resistant ABS/ polycarbonate enclosure with a hinged, 
secured door. With the optional splash guard installed, the enclosure is IP54 rated and ideal for use in water spray
or wash down applications.
