Description
The Crowcon XSafe is the safe-area member of the Xgard fixed detector family — the same robust junction-box design as the hazardous-area Xgard types, built for areas that are not classified as hazardous, so it carries no hazardous-area certification. This page lists two XSafe builds in one dropdown.
The X Safe Bright (XSB) configurations bring the Xgard Bright platform to safe areas, with a bright OLED display, non-intrusive calibration with a magnetic wand, 4-20mA and RS-485 Modbus RTU outputs, alarm and fault relays and optional HART, plus long-life sensor options including MPS, infrared and PID across toxic gases, carbon dioxide and volatile organics. The classic XSafe configurations are the original safe-area flammable-gas detector for methane or propane at 0-100% LEL, using a catalytic bead (pellistor) sensor with a choice of 3-wire 4-20mA (mA) or 3-wire mV bridge (mV) output for a control panel, and every classic configuration is NON CERT, exactly as stated in the dropdown. Every configuration on this page is a safe-area build, so none of them may be installed in a classified hazardous location.
How to read the configuration code: XSB codes are X Safe Bright builds — housing (A1 = aluminium M20, A3 = aluminium M20(1/2), S1 = stainless steel M20, S2 = stainless steel 1/2" NPT), the 03 safe-area block, then comms (HA/HB/HC = HART fitted, ZA/ZB/ZC = no HART), R = relays fitted, and the gas code. Classic codes (C011xxx / C019xx) are the original XSafe — mA or mV output, methane or propane, M20 or 1/2" NPT — and are NON CERT. Every configuration in the dropdown also spells out its build, gas and range in full.
Common Applications:
Battery & Energy Storage • Warehousing • Water & Wastewater • Chemical Plants • Manufacturing • Commercial Buildings

- Safe-area, non-certified design — for areas that are not classified as hazardous; no ATEX, UL or CSA hazardous-location approval applies to any configuration on this page
- Two builds in one product: X Safe Bright (XSB) display transmitters and classic XSafe mA / mV detectors
- XSB: bright OLED display with non-intrusive calibration and setup via magnetic wand — no need to open the housing and no hot-work permit
- XSB: 3-wire 4-20mA (sink or source) and RS-485 Modbus RTU outputs, with alarm and fault relays as standard and HART 7 on the configurations that state it
- XSB: long-life sensor options — MPS and infrared flammable sensors (10+ years) and PID for volatile organics — minimise sensor replacements
- XSB: electrochemical sensors for toxic gases including hydrogen sulfide, chlorine, chlorine dioxide, ammonia, nitrogen dioxide, nitric oxide, sulfur dioxide, hydrogen cyanide, hydrogen peroxide and ozone
- Classic XSafe: catalytic bead (pellistor) sensor for methane or propane, 0-100% LEL
- Classic XSafe: 3-wire 4-20mA (mA) or 3-wire mV bridge (mV) output to suit the control panel
- Universal Xgard junction box — sensors and sinters are plug-in, so replacement takes minutes, and many spares are common across the Xgard family
- Wall or ceiling mounting with no additional brackets; accessories available for duct mounting, sampling and remote gassing
