## Description

The Sensaphone 400 Monitoring System offer small-business owners, vacation property owners, and other property managers an easy and inexpensive way to monitor a remote facility. These systems notify you if they sense undesirable temperatures or other conditions. When the system is connected to a standard telephone line, you can record custom “Alert Condition” notifications and receive alarm messages in your own voice. This system can set off a local alarm if a phone line is cut and control a thermostat to adjust site temperature between two set points. Nonvolatile memory retains system settings in the event of power loss. You can call in by phone to get the status of each monitored condition. The system will also allow you to listen in to sounds on site.

## Questions & Answers

**Q: Can the temperature controller be used to turn the heat up to 117-127 degrees fahrenheit if that’s what i want it to do and my hvac output is capable?**
A: For use exclusively with the Sensaphone 400 and 800, this is a "setback" thermostat with an LCD readout. It lets you enter the desired setpoint for both your "away" and "home" temperatures. A control signal, sent from your Sensaphone, switches between these two settings. Product Number: FGD-0064

**Q: Can unit be used with internet phone systems?**
A: The Sensaphone 400 has an analog phone connection so it can be used on VOIP systems as long as you can use any analog phone on them. If you need to use digital phones on the system the Sensaphone will not be able to work.

**Q: Does 400 Sensaphone replace a 1104 model? Will the sensors hook up the same?**
A: The 400 is the replacement model for the old 1104. Any sensors you had on your 1104 should be able to hook up the same way to the 400.

**Q: In order to use this unit, do we need to order sensors?**
A: No, you can use it right away to monitor temperature, power failure & smoke alarm sound. You can add sensors as needed
