It is comparable to a digital communicator, but instead of transmitting signals over the telephone lines, it transmits radio signals to the central monitoring station using the control channel of the AMPS cellular phone network.

  • Page 25 The disadvantage to this selection is that the radio will not transmit when the battery fails. If it is possible to budget 400mA to the 7845CZ or if drawing that amount of current for 3 seconds is not a problem, then the response to the current limit question should be NO.
  • Page 26 The 7845CZ performs a battery test under load on a periodic basis. During this test, if the battery drops below 5.7V, a low-battery message is generated to indicate that the battery should be replaced.
