Product Description

2 in 1 RV CO & Propane Gas Detectors

R502 Detector adopts two independent and highly sensitive sensors specifically designed for RVs.It is used to detect carbon monoxide & propane gas leak in Motorhome Travel Trailer, Motor Coach, Truck Camper, RV and other similar applications.

Step 1: Enter into 180s Warm-up period

Power on. The buzzer beeps “Di” twice, two red lights will flash and the green light will always be on. The display will show “-”. Please wait three minutes for sensor preheating.Note : Don’t apply gas to test during the warm-up process because the gas won’t be detected.

Step 2: Normal working

Once the warm-up process is finished, the two red red lights will be off, and the green power indicator will remain on. The display will show “0”.Note : Don’t paint, don’t apply abrasive solvents or other cleaners. Chemicals can permanently damage or temporarily contaminate the sensor inside.

Step 3:CO concentration ≥100ppm or gas concentration ≥ 5% LEL will trigger the alarm.

When the carbon monoxide concentration is equal to or higher than 100PPM, the detector will sound an alarm and the carbon monoxide red alarm indicator will flash.When the carbon monoxide concentration is more than 10 (10000ppm), the number on digital display will be changed into letter A.When the gas concentration is equal to or higher than 5%LEL, the detector will sound an alarm and the gas red alarm indicator will flash.When the gas concentration is more than 10 (=10% LEL, 5000ppm), the number on digital display will be changed into letter A.

Step 4: Get after service support when two Red Lights will Flash on

If the two red lights will flash or Digital Display will show ERR (abbreviation of error), which means sensor has lost efficacy and can’t finish data collection.Engineers on staff from factory help to answer any questions you have related to products usage of natural gas, propane, methane, and sewer etc.
