LPG/Gas Vapor Monitor with Alarm
With Solenoid Contoller & Remote Sensor
The GD20B Gas Vapor Monitor detects gas vapors at 10%, 20% or 30% of the concentration required for an explosion (LEL or Lower Explosive Limit). The desired sensitivity can be selected from the front panel and stored in the non-volatile memory. When activated, the built-in 85dB alarm will sound and it will remove power to your LPG solenoid. The alarm will continue to sound as long as the sensor detects a dangerous concentration of gas vapor or until the "wait button" is pressed. If the alarm is silenced by the use of this button, the GD20B will automatically arm the alarm again as soon as the gas vapor has subsided.
An instruction manual and all mounting hardware is provided.
Spare gas sensor assembled with 16-ft cable (5 meters) can be ordered separately - Sku# 709674.
