Do you want to know how hot or cold it is at your desert retreat or mountain cabin, and have the ability to switch on the AC or heat before you arrive? How about being notified if a leak is detected in your home or office, or if your freezer full of albacore and wahoo from your 5-day overnighter looses AC power? When connected to a phone line, all this is possible with the Sensaphone Monitoring System.
The Sensaphone monitoring system is a fully-programmable, environmental monitoring system with the ability to dial up to four telephone numbers. Up to four sensors (zones) can be connected to the Sensaphone. Temperature limits are easily programmed, and a variety of external sensors are available for just about any application. When a zone is triggered by one or more of the sensors, the Sensaphone dials out, identifies itself through a user-recorded voice message, and recites the status of that zone. The user can also call in to the premise where the Sensaphone has been installed to obtain the current status.
The Sensaphone “out-of-the-box” can monitor the following:
- High sound levels
- AC power failure (the Sensaphone has a battery backup)
- Local temperature (via a factory installed thermistor on Zone 1)
- “Listen-In” capability
Additional external sensors can extend the monitoring capabilities to include:
- Intrusion detected by magnetic contacts, motion detectors, or pressure mats
- Water leaks and seepage
- Remote temperature
- Other conditions requiring unique monitoring solutions
In addition to being able to monitor a premise, control is possible through the use of an on-board relay. The Form-C relay can be controlled via telephone to directly switch on or off a low voltage device, such as a thermostat, or to indirectly control larger appliances or devices requiring higher power through the use of an external heavy-duty relay.
In the case of a set-back thermostat, applying 12 VDC to the thermostat will cause the ‘stat to switch between two pre-set temperature settings. For example, if the mountain cabin is vacant, preset the temp to 45 degrees. When the weekend rolls around and it’s time to head for the hills to play in the snow, call the Sensaphone, apply 12 VDC to the ‘stat via the relay to use an “occupied” setting of , let’s say, 70 degrees. Periodically call the Sensaphone at the cabin to verify that the temperature is indeed rising…it’ll be toasty warm when you get there! Check out the diagram below to see how a set-back thermostat is connected to the Sensaphone Monitoring System.
The installation of a Sensaphone Monitoring System, be it in your home, computer server room, greenhouse, wine cellar, walk-in humidor, priced tropical fish habitat, or any application requiring a stable environment, is a very effective and practical solution on being able to keep an eye on things. It’s like having your very own watchman on duty that never sleeps or leaves his post, all knowing, ready to call you at the first sign of trouble.
