Question: How many places can i monitoring and how far? can i connect with other sensors like motion?
Document: Amazon credited my account and were very polite in the e-mail they sent, but I would rather have the item. Free shipping is not such a good deal after all. I will explore other options for monitoring my sump pump system. Happy with my shopping experience ?????? Nope....... Will I come back ? Only if it is to my advantage with price, etc. Probably not. Too many places have a better shipping system.
Most telephone answering systems costing 1/2 to 1/3 the price of this unit provide examples of a far more sophisticated and easy to use interface.This phone-out alarm actually works, and since there seems to be nothing else on the market that has a better interface or lower price, I'm keeping it. But that doesn't mean that I have to like it -- I really don't.
Works as advertised. I have a sump pump in an office location where we had water damage that cost over $10,000  (sump pump failed)  Purchased this after that incident, and have been notified several times that the power was out. It calls up to 3 numbers, works like a charm, and has paid for itself many times over.
I let the unit continue for 1 hour and every 20 minutes a tone alarm would sound. If your sump pump fails and you miss the alarm because you are at the far end of the house, then you basement would be flooded by the time you heard the next one. I would also like a 0 time option like the other reviewers. I belive this 20 min.
The hardest part about being hundreds of miles from your second home is not knowing what's going on there. Sure you could get an Internet connection and hook up sensors and cameras and monitor it from elsewhere but the expense of all that just didn't make sense to us.
Set up was not complicated and so far it has tested out just fine. No actual alarms yet. I would recommend this item.
Unit works well so far. However I have ordered 2 units and both came with batteries that would not work. Please fix.
This product is great for home protection. It covers power, flood, and freeze protection. I have a good setup with this unit and hope to share it with other people.First I was able to buy 2 additional water sensors so that it could monitor each sump pump. I ran a telephone wire to each sump pump and then connected it with the sensor.
Reliance does not list extra water sensors on their webpage, but you could just use the end of the second phone cord as the sensor, as long as you separate the conductors in the same manner as the one from the factory.The THP201 has switches for selecting pulse or tone type phone dialing, and for selecting either a 5 minute or 30 minute delay between sensing an alarm and calling you about it.
Cheap solution for data center monitoring compared to other at $$$ more. I've deployed in several locations and am happy with the product.
