At a glance
- Hydrogen at 1000ppmThe gas detected is Hydrogen (H2) at 1000ppm on a factory calibrated detector.
- Modbus RTU Digital LinkThe detector puts out Modbus RTU on an RS 485 Modbus line.
- Twin Power RelaysTwo relays carry 5 A across 24 V DC / 240 V AC contacts.
- VSC and VSM4 VisibilityOperating status of the Modbus version reaches VSC and VSM4 through their integration.
- Microbore Tube FittingThe head takes VESDA-E VEA micro bore tube sized 6 mm (1/4”) OD, with VEA tubes entering the flexible tubing by 15mm (0.6 in) or more.
- Sealed Detector BodyRated IP65, Type 4 (NEMA 250), the polycarbonate (charcoal colour) enclosure runs to 113 x 113 x 59 mm at 500 g.
Description
Battery rooms, fuel storage areas and confined spaces are among the settings for XCL-VEA-H2-RM, which places hydrogen measurement in-line within the VESDA-E VEA microbore tube network.
Its polycarbonate housing, charcoal in colour, spans 113 x 113 x 59 mm at 500 g and holds an IP65, Type 4 (NEMA 250) rating. Ambient limits are −20 °C to +50 °C in use and 0 °C to +30 °C in store. Integral alarm status LEDs indicate locally, and a Bluetooth 4.0 (Bluetooth Low Energy) link reaches a compatible smart device up to 10m off (mobile device dependent).

EN/UL/IEC61010-1 conformity sits alongside CSA-C22.2 No. 61010-1-12 certification; EN 50270 covers EMC while RED, FCC and BT SIG cover radio, and AS 1668.2 also applies. XCL-XRL-SC-H2 renews the sensing element, and XCL-VEA-CAL, XCL-FILTER, XCL-M20-CG and XCL-COVER complete the service set.
XCL-VEA-H2-RM is a hydrogen gas detector covering 1000ppm, factory calibrated and placed in-line in a VESDA-E VEA microbore tube network using flexible tubes. It joins VESDA-E VEA micro bore tube sized 6 mm (1/4”) OD, and every VEA tube enters the flexible tubing by 15mm (0.6 in) or more.
Output is digital: a Modbus RTU stream on an RS 485 Modbus line, backed by two relays that carry 5 A across 24 V DC / 240 V AC contacts. Remote visibility comes from VSC and VSM4 integration covering Modbus version detector operating status, and the detector also drops into PLCs, HVAC, BMS or FACP.
The Modbus supply window runs 9 to 32V DC around a nominal 24 VDC, with 24V AC 50/60Hz as the alternative; the 24V DC inrush figure is 850 mA and adding relays draws a further 0.6W total. Pluggable rising clamp terminals accept 0.5 to 1.5 mm² conductors, humidity is allowed across 0 to 99% (non-condensing) and pressure across 95 to 110 kPa.
