The P-1B-R Propane Fume Detector is an effective means to monitor propane fumes in a compartment or leaking fuel systems. The system uses a sensor, located in a place of interest, and a central display unit that notifies you of the state of the system.
There are 3 LEDs located on the Display Unit for each channel on the system. The Green LED, located at the top, indicates that the system is operational. The Yellow LED, located in the center, indicates that there is a Fault in the system. This is to notify the user to check the connections and wire runs of the sensors. There may be a break in the wiring or a disconnected sensor on that channel.
The Red LED, located at the bottom, indicates a fume buildup of 20% of the LEL (Lower Explosive Limit) which is considered an alarm. The alarm horn will sound when the Red LED is illuminated
The alarm status will continue as long as the fume level remains at an elevated level. The alarm horn may be silenced by pressing the “Check/Reset” button. The alarm will reactivate after 30 seconds as long as the Detector remains in alarm status. The problem should never be considered corrected as long as the Red LED is illuminated.
