ABSTRACT:
A security system includes a sensor and a control panel that receives transmissions from the sensor. The sensor has a user-operable testing actuator that tests a condition sensing device in the sensor. A method of operating the sensor includes generating, in response to actuation of the testing actuator in the absence of a predetermined condition, a transmission from the sensor including information indicating that a test of the sensor has been conducted. The method further includes receiving by the control panel, in response to actuation of the testing actuator in the presence of the predetermined condition, a transmission from the sensor indicating that the control panel should not report to a monitoring station.
