last night my alarm went off while disarmed. This made me jump out of bed because it only meant one thing - burst pipe or fire.
In checking it out - the RE-219 sensor reported a freeze condition in the space it monitors. The sensor is mounted about 3 feet off the ground on a wood shelf made of 2x4’s with a wire running to the floor for the water probes. The room had a temperature of at least 50 degrees - I could not make a steam breath no matter how hard I tried. Unfortunately I have no way to measure the temp in the room - but let’s say it was warmer there than it was in my interior staircase immediately above the space (leaky 110 year old house!).
So the obvious things are - faulty RE-219 sensor; the wood of the frame of the shelves got so cold it set off the sensor (unlikely - it is wood after all) - or?
Is there any place I can look to see the technical detail of the alarm condition? I believe that once cold is achieved the sensor simply kicks relay open - so doesn’t report a temp. If this is incorrect, how can I find the temp?
Is there a way to set the temp to a specific level in the sensor?
Right now I have it disabled in the panel. After the alarm went off once and I investigated, I turned off reporting. It went off again 15 minutes later. At that point I disabled it completely.
Thanks in advance!
