A smoke detection device for use in a portable device such as a mobile terminal. The smoke detection device comprises a light emitter and a light detector disposed on different locations on the portable device so that when smoke or an intruding object is presence in the light path of the light emitter outside the device housing, it causes the light emitted by the light emitter to be scattered or reflected. When the light detector senses the scattered or reflected light, it can cause an alarm signal to be produced by the portable device. The emitted light can be in the infrared region so that the detection is independent of the ambient light. Alternatively, the light emitter is operated in a pulsed mode. Additional light emitter and light detectors can be disposed on the portable device for proximity sensing in addition to smoke detection.

A networked system of addressable alarms notifies citizens of conditions within a community, A control center is communicably linked via the network to alarm devices such as smoke detectors in controlled environments such as buildings in order to alert citizens of conditions outside of the controlled environment, which may be situations requiring an emergency response. The alarm devices may also be capable of sending local status information (e.g., fire alarms, security alarms, etc.) to the control center so that the control center can respond as necessary to any local emergencies.

A smoke detector system wherein a smoke alarm which is turned “on” by the sensing of smoke is turned “off” for a predetermined period of time using a disable signal transmitted by a remote controller and an indicator light is turned “on” to indicate that the alarm is turned “off”, and wherein after the predetermined period of time, the alarm is returned to a normal state and the indicator light is turned off. Thus, when the smoke detector alarm is turned “on” by an erroneous or non-lethal sensing of smoke, a housekeeper can readily turn “off” the alarm for the predetermined period of time and see by the indicator light that the alarm is off for that period of time. Advantageously, the remote controller comprises a container having a permanent magnet and the remote controller is physically apart from the detector so that the controller can be conveniently stored, for example on a refrigerator door for quick use and storage.
