Smoke detector mounted on a ceiling. A smoke detector is a device that senses smoke, typically as an indicator of fire.Smoke detectors/alarms are usually housed in plastic enclosures, typically shaped like a disk about 125 millimetres (5 in) in diameter and 25 millimetres (1 in) thick, but shape and size vary.
Kidde (/ ˈ k ɪ d ə / [2]) is an American multinational company that manufactures and distributes fire detection and suppression equipment, as well as smoke and CO alarm units. Kidde is one of America's largest manufacturers of smoke alarms [3] [4] and fire safety products. [5]
Fire alarm systems are required in most commercial buildings. They may include smoke detectors, heat detectors, and manual fire alarm activation devices (pull stations). All components of a fire alarm system are connected to a fire alarm control panel. Fire alarm control panels are usually found in an electrical or panel room.
An optical beam smoke detector is a device that uses a projected beam of light to detect smoke across large areas, [1] typically as an indicator of fire. [2] They are used to detect fires in buildings where standard point smoke detectors would either be uneconomical [ 3 ] or restricted for use by the height of the building.
This pattern, which is also used for smoke alarms, is named the Temporal-Three alarm signal, often referred to as "T-3" or "Code-3" (ISO 8201 and ANSI/ASA S3.41 Temporal Pattern) and produces an interrupted four count (three half second pulses, followed by a one and one half second pause, repeated for a minimum of 180 seconds).
On September 4, 1992, BRK recalled all hardwired smoke alarms under the series 1839I and 2839I due to testing programs determining that corrosion could form on the alarm horn's electrical contacts, causing the piezo to fail to make any noise. [6] In May 2006, First Alert combination smoke alarms were recalled due to draining batteries rapidly. [7]
An aspirating smoke detector (ASD) is a system used in active fire protection, consisting of a central detection unit which draws air through a network of pipes to detect smoke. [1] The sampling chamber is based on a nephelometer that detects the presence of smoke particles suspended in air by detecting the light scattered by them in the chamber.
The operation of single interlock systems are similar to wet systems except that these systems require that a "preceding" fire detection event, typically the activation of a heat or smoke detector takes place prior to the "action" of water introduction into the system's piping by opening the pre-action valve which is a mechanically latched ...
