The Sensaphone temperature alarm and power alarm has many powerful and useful features. You can set the sensitivity or duration of an alarm condition, depending on your needs. Or you can turn them on or off. (For example, you can set the power alarm sensor to notify you when power is out for anywhere between 1 and 199 seconds consecutively. Or you can disable power notification completely if outages are a routine event you don't need to be warned about.)  As well, by adding accessories, such as the water bug,  your sensaphone can detect the presence of water, perhaps due to pipe rupture or leakage.  This is especially great for monitoring sump pits.  Other Sensaphone accessories available will enable you to monitor break-ins through windows or doors, overheating of your home computer and humidity changes at a remote location. 

Model 400 temperature alarm accommodates up to four external sensors. Model 800 accommodates up to eight external sensors — ideal if you want to add multiple sensors to use your Sensaphone as a "silent" security alarm with magnetic contacts for doors and windows and pressure sensitive mats. (You can also connect multiple sensors in a series connection to a single terminal on any model.)

When an alarm condition occurs, the dialer calls up to four (Model 400) or eight (Model 800) phone numbers that you choose. The alerted person on the other end of the line receives a voice message, describing the status of the power, temperature, backup battery supply and status of each of the sensors. He or she can then listen in to sounds in the home or business to help determine the problem.

Installation is simple. Just plug the console into an electrical outlet, connect it to your phone and set it up, using easy-to-follow instructions. No monthly monitoring fees to pay. This product is a must to protect your home or seasonal property or operate a greenhouse in cold weather.
