Unmanned system (US) for smoke detector testing
Methods, devices, and systems for an unmanned system (US) for smoke detector testing are described herein. In some examples, one or more embodiments include a test kit, a processor, and a memory having instructions stored thereon which, when executed by the processor, cause the processor to perform a test procedure on a projected beam smoke detector in a facility using the test kit and communicate a result of the test procedure to a smoke detector network associated with the facility.
ALARM SYSTEM COMPONENT WITH UNPOWERED EVENT DETECTION
A component 10 for use in an alarm system includes a component controller 12 and an offline configuration module 14. The offline configuration module 14 includes a passive RFID tag and is configured to receive and store an indication of at least one configuration parameter wirelessly transmitted to the configuration module.

Smoke detector device with secondary detection chamber and filter
Devices, systems, and methods for providing a smoke detector device with a secondary detection chamber and filter are described herein. One smoke detector device includes a first smoke detecting chamber, a first light source, a first light sensor, an air movement device to move at least some of the particulate into an inlet of a second smoke detecting chamber, a filter material positioned such that the particulate must pass through the filter material to enter the second chamber, the second chamber formed therein to receive particulate from the first chamber, a second light source, and a second light sensor to determine whether smoke particles are present in the second chamber.
Fire detection system diagnostic systems and methods
A tool for performing diagnostics on a fire detection system includes an induction coil which includes two halves that may be selectively opened and closed to surround a wire in the system and sense current through the wire. A diagnostic module and a conduit provide communication of data of the sensed current between the induction coil and the diagnostic module. The diagnostic module is configured to decode the data to interpret communications sent through the wire.
TEST LAMP FOR MULTI-SPECTRUM MID-IR FLAME DETECTORS
Methods and systems for testing a flame detector include receiving, at a trigger sensor of the flame detector, a coded trigger signal from a test lamp and performing a self-test operation of the flame detector in response to detection of the coded trigger signal. The flame detectors may include a trigger sensor configured to detect a trigger signal received from an external source. The trigger sensor has a field-of-view and sensitivity that is the same a flame detection sensor of the flame detector. The flame detector will perform a self-test operation when the trigger signal is received at the trigger sensor. Test lamps include a light source configured to emit light and a controller configured to control the light source to generate and output a trigger signal, wherein the trigger signal is configured to cause the flame detector to perform the self-test operation.
Smoke sensor with test switch and method of operation thereof
A smoke sensor with test switch and a method of operation thereof are disclosed. The smoke sensor is an example of a fire alarm initiation device that is deployed in a building, and is part of a fire alarm system at the building. Fire alarm initiation devices include a fire detection system for detecting an indication of fire, a normally deactivated test switch that is activated during testing of the device, and a controller. The controller senses the activation of the test switch, and in response, prevents the device from sending an alarm message upon the fire detection system detecting the indication of fire. In one example, the test switch is a magnetic reed switch that is activated when a hood of a test tool is placed over the device, the hood including a magnet that comes within proximity of the magnetic reed switch to activate the switch.
Self-testing fire sensing device
Devices, methods, and systems for a self-testing fire sensing device are described herein. One device includes an adjustable particle generator and a variable airflow generator configured to generate an aerosol density level sufficient to trigger a fire response without saturating an optical scatter chamber and the optical scatter chamber configured to measure a rate at which the aerosol density level decreases after the aerosol density level has been generated, determine an airflow rate from an external environment through the optical scatter chamber based on the measured rate at which the aerosol density level decreases, and determine whether the self-testing fire sensing device is functioning properly based on the fire response and the determined airflow rate.
Self-testing hazard sensing device
Devices, methods, and systems for a self-testing hazard sensing device are described herein. One device includes a sensor, a wire dipped in a material, a controller configured to provide a current to the wire to heat the material and generate aerosol and/or carbon monoxide, and an airflow generator configured to provide the aerosol and/or carbon monoxide to the sensor. The controller configured to determine whether the self-testing hazard sensing device is functioning properly using the aerosol and/or carbon monoxide provided to the sensor.
