S3849R454B - R-454B Gas Detector 0-20% LEL, Infrared sensor - SMART3-H LITE
S3849R454B SMART3-H refrigerant gas detectors are employed to detect refrigerant R-454B compounds (%LEL) in non classified areas.
Designed to meet with cost effective requirements, SMART3-H-L allow to monitor A1 and A2L refrigerant gasses in hotel and building applications. Three mode status LEDs offer a visual indication of the detector' status while an internal buzzer activates to warn of any fault or alarm condition.
The detectors employ a unique cost-effective IR sensor and provide RS485 communication and two pre-set relay outputs.
The detectors are rated to IP 42 and are available at 12-24 Vdc
