1. An apparatus comprising:
- a housing, the housing carrying a selected externally accessible port;
an ambient condition sensor carried by the housing; and
control circuits in the housing, coupled to the sensor, the control circuits include modulation circuits, responsive to a predetermined condition, which generate one of a frequency modulated or an amplitude modulated signal at the port.

Abstract
An ambient condition monitoring system includes a plurality of detectors such as smoke detectors, gas detectors, or fire detectors. Each of the detectors has two sets of input/output ports. One port can communicate with a system control unit. The second port can communicate with a local wired network to which is coupled a plurality of output devices. The output devices can be activated by the respective detector using a modulated control signal.
