Technical Description – Site Sentinel CXT Wireless Controller
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.
A Closer Look
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.
Depending on the application and the types of flames most likely to be encountered in a facility, personnel can choose from a wide range of detector offerings to meet the facility’s detection needs. Detectors include Single IR, Triple IR (IR3), Multi IR, UV, UV/IR2.5μm, UV/IR4.5μm and Ultra-Fast UV/IR detectors. As an additional option, detectors can be ordered with or without built-in test (BIT) capability.
