The Sensaphone combines modern electronic solid state technology with your existing telephone system to provide an around the clock monitoring and alarm system. While you are absent from your greenhouse, the Sensaphone monitors ambient conditions and three electrical contacts. In the event of AC power failure, 6 "D" batteries (not included) take over for up to 15 hours. When greenhouse conditions fall outside the parameters you have established, the Sensaphone will call up to 4 telephone numbers in sequence until a telephone is answered. The answering party has 30 seconds to call the Sensaphone back to deactivate this calling feature. The Sensaphone requires a dedicated telephone line. It will not call the line it is attached to, or to a "party-line". You can call the Sensaphone at any time to verify the conditions in your greenhouse. When it answers your call, it will reply in synthesized English with the same information previous described, plus the values of the high and low ambient temperature parameters programmed. The Sensaphone comes with a 'local temperature sensor' that will read the temperature at its location. To get the Sensaphone to report the current temperature within the greenhouse, you should purchase the waterproof 'Remote Temperature Sensor'. This will allow you to read temperatures as far as 250' away from the Sensaphone location. (Bell Wire is not included.)
