Our solonoid panel also is a smart gas-sniffing device with a remote sensor in the bilge
and an optional second zone for another location. It doesn't just sense propane, but other dangerous gasses and vapors and will emit an audible alarm
and immediately shut off the solonoid if it is on. The solonoid is controlled by an on/off switch on the panel.
We leave the panel on whenever we are on the boat
. As well as a separate CO detector panel, but aleays shut off the solonoid using the button on the panel when we are done cooking.
I just checked the power consumption
of our solonoid and it is closer to 7 watts, not 5 as I said above. That's a lot of juice. But the sniffer panel itself draws an additional 5 watts even when the solenoid is off (or even physically disconnected from the circuit) because that gas sensor in the bilge is a power hog I guess, and whatever electronics
are active inside panel itself. I bet if we added a second sensor to zone 2 on the panel it would draw even more power.
I am not happy with this electrically inefficient gas sensor & panel but I guess that is the price
to pay for safety
. I suppose I could put a switch in line with the power feed to turn off the entire panel when we are not using the LP but then we would lose the protection of the explosive fume detector. It will detect many other explosive gasses such as gasoline, alcohol, acetone, various paint
thinners, butane and other stuff that might be stored aboard and could possibly spill in a locker and make its way to the bilge if they were heavier than airnornthe biat was really closed-up tight. It will even alarm
if it senses a lot of hydrogen gas such as if the batteries
are being excessively overcharged. But hydrogen is lighter than air so there would need to be a lot of it built up in a closed-up boat
for it to trip a sensor down in the bilge.
The instructions that come with the device say to keep it powered up whenever the boat is occupied:
"CAUTION: NO POWER ON/OFF SWITCH IS PROVIDED FOR THIS UNIT. TO
FUNCTION AS INTENDED, THE S-2A MUST BE CONNECTED TO A CORRECT
POWER SOURCE, AND FOR MAXIMUM EFFECTIVENESS, BE POWERED AT
ALL TIMES WHILE ABOARD. IF POWER IS ON AND LEFT UNATTENDED FOR AN
EXTENDED PERIOD OF TIME, BATTERY
POWER MAY BE DIMINISHED."
