Use of optical reflectance proximity detector in battery-powered devices
Various methods, systems, and devices for identifying a condition of a battery-powered device are presented. For example, a device may include a smoke detection sensor that detect smokes and, in response to detecting smoke, generate a smoke detection signal. The device may include test circuitry that tests an aspect of the battery-powered device. The device may include an audio output device that outputs a sound in response to the test circuitry determining a particular condition is present. The device may include a proximity detector that monitors for a wave movement of an object within a distance of the battery-powered device and generates a proximity detection signal when the proximity detector detects the wave movement performed by the object within the distance of the smoke detector device.
SMOKE DETECTOR WITH INTEGRATED SENSING
A smoke detector and method for testing a smoke detector are provided. The smoke detector includes a housing defining a chamber, an emitter, and a receiver. The housing includes an inlet port and an outlet port configured to allow an airflow to pass through the chamber. The emitter is configured to emit light into the chamber. The receiver is configured to receive light reflected by ambient materials in the airflow passing through the chamber. The smoke detector includes an entry point and an exit point, defining a channel therebetween. At least a portion of the airflow passes through the channel. The channel is in fluid communication with a sensor. The sensor is configured to detect at least one of a pressure differential and a mass flow of the airflow. The smoke detector and method for testing the smoke detector enable in situ testing of the smoke detector.
Method and apparatus for testing fire alarm initiating devices
According to systems and methods for testing alarm initiating devices of a fire alarm system, a control panel of the fire alarm system is placed into test mode. Then, during a walkthrough test, an inspector activates an inspector-activated mechanism of a device. This sends a test mode signal to the control panel, which places the device into a test mode. The inspector or inspector then manually activates the device. The control panel initiates a fire alarm condition in response to a received device signals while the control panel not initiating a fire alarm condition when the device signals are indicative of a fire if the device signals were from alarm initiating devices in the test mode. Alternatively, the control panel places a group of alarm initiating devices into test mode on a rolling basis. As the inspector tests the devices, additional devices are added to the group and previously tested devices are returned to normal operation mode.
