<p>A detector for a flow condition within a pipe, and a transmitter that transmits a signal in response to the sensed flow condition. The detector may include a tamper sensor that senses a tamper condition, and an enrollment device that senses a user-initiated stimulus different from the sensed condition and the tamper condition. The transmitter transmits an enrollment signal when the user-initiated stimulus is sensed, the enrollment signal including an identification code associated with the detector for enrolling the detector. The use of a transmitter permits communication of a sensed flow condition to a remote control panel without the need for additional wiring and conduit hardware. The incorporation of a tamper sensor ensures the integrity of the detector against efforts to disable its sensing or communication capabilities.</p> |
