Question 1

How do you splice in more wires to create a dual sensor using the one box?  Want to put 1 box and 2 sensors in a tight location.

Accepted Answer

For the price, why splice wires, the leads can be extended to 6 feet.  What I would recommend is to place the sensor on a sheet of paper towel.  Any moisture will wick up to the contacts.  Also you can cover a bigger area where just a corner of the paper towel will transfer the liquid by capillary action to the contacts.

Question 2

is it easy to reset

Accepted Answer

To reset all you have to do is dry the leads and it will stop alarming. Please contact us directly if you are in need of further assistance at 800.911.0466 ext 3. We are open M-F 9-5 CST and would love to assist you.

Question 3

if the battery is low, will it give you some sort of audible/intermitten beep warning (like a smoke alarm)?

Accepted Answer

I am going to buy this and a 9v battery eliminator that plugs in(about $10). Never have to worry about batteries. If a Sump is involved maybe a very small UPS could be a solution(about $30). There is a mini ups on Amazon. You can get a 9v battery clip and wire up. 
Good 9V batteries aren't cheap either.
 Consider what repairs could cost.

Question 4

what is size of sensor

Accepted Answer

2-1/2" X 1" X 1/8" plastic plate.  there are 2 metal discs a little smaller than a dime fixed to that plate. There is a 10 feet long wire would up inside the case that attaches the sensor to the case. The case has 2 holes on the back to mount on wall if you want to do that. There are two mounting holes in the sensor plastic plate if you want to mount that, such as with any tiny screws you happen to have. The instructions say you can splice up to 100 feet of wire onto the 10 feet wire in order to have the alarm somewhere far away from where the sensors are placed. Teeny tiny wire is OK to use since the voltage is only 9 volts.
