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.
