Fire Alarm Sensor

[BottomLine]

I need to replace on of the fire sensors in the engine room that was causing the alarm bell to ring constantly. My alarm system which was installed at the factory has "Sea Alarm II" engraved on the front.
I searched but couldn't find anything under that name. I did fine a site for "Aqua Alarm" which has components similar to my system. They offer two replacement fire sensors. One goes off at 135 degrees and the other at 195. My sensor doesn't have any markings on it and I don't see anything in the owner's manual which indicates what temperature the sensors will set the alarm ringing. Any thoughts on 135 or 195?

Check with Danny at High Tide Marine. I ordered some from him.

Thanks Jack. I called him and he said he buys them from Aqua Alarm. These are the ones that are about 5 in. in diameter.
