Wireless CXT Controller

Introduction

Detcon Site Sentinel CXT Controller is a SmartWireless® gas detection and control system that provides operator interface to the network and real time status display of all network devices. The Site Sentinel CXT is compatible with Detcon’s Model RXT transceivers and CXT gas detectors. Flexible and expandable, a Site Sentinel network can include up to 32 devices and consist of any combination of wireless and/or wired sensors, one or more Site Sentinel control panels, and alarm warning devices.

Command functions include alarm reset, alarm acknowledge, alarm test and radio silence. In normal operation the control panel provides real time display of gas concentrations or the status of other field devices; battery charge levels, network RF signal quality and any number of fault diagnostic conditions affecting either an individual field device or the entire network. These fault conditions are displayed on the control screen.

Options include audio alarm, visual alarm, external alarm port, alarm reset switch and up to 4 external wired sensor inputs. Standard features include a power-in port and power switch.

The control panel is rated for Class 1, Division 2; Groups A, B, C, D hazardous areas. Operator interface is non-intrusive via magnetic contact switches located behind the glass lens cover. This advanced design takes advantage of a low power LCD with back light and ultra low power components. Power is provided by an internal rechargeable battery and/or 11.5 to 30VDC. Operating time is 1-2 months before recharge is required. An optional solar charging panel can be used to extend operating time for virtually any application.
